In a science experiment the temperature of a liquid is first read at 11.15am. If the temperature is read every 12 hours, at what time will the eight temperature reading be taken?
If the temperature is read every 12 hours, then the eighth temperature reading will be taken at 11.15 pm three days after the first reading.
What is temperature?Temperature is a measure of the degree of hotness or coldness of a substance or object, typically measured using a thermometer in degrees Celsius or Fahrenheit.
If the temperature is read every 12 hours, then the time interval between two consecutive temperature readings is 12 hours.
To find the time of the eighth temperature reading, we need to add 12 hours for each of the previous seven temperature readings:
First reading: 11.15 am
Second reading: 11.15 am + 12 hours = 11.15 pm
Third reading: 11.15 pm + 12 hours = 11.15 am (next day)
Fourth reading: 11.15 am (next day) + 12 hours = 11.15 pm (next day)
Fifth reading: 11.15 pm (next day) + 12 hours = 11.15 am (two days after the first reading)
Sixth reading: 11.15 am (two days after the first reading) + 12 hours = 11.15 pm (two days after the first reading)
Seventh reading: 11.15 pm (two days after the first reading) + 12 hours = 11.15 am (three days after the first reading)
Eighth reading: 11.15 am (three days after the first reading) + 12 hours =

will the product of 2 numbers increase or decraese and by what percent if one of them is increased by 50% and the other one is decraesed by 50%
Answer: Let's assume the two original numbers to be x and y.
If one of them is increased by 50%, then the new value will be 1.5x, and if the other one is decreased by 50%, the new value will be 0.5y.
The product of the two new numbers will be:
1.5x * 0.5y = 0.75xy
So, the new product is 0.75 times the original product. This means the product of the two numbers has decreased by 25%.
To summarize:
If one number is increased by 50% and the other number is decreased by 50%, the product of the two numbers will decrease by 25%.

What is 2.655 as a mixed number in its simplest form. Please show your work.
In response to the question, we may say that Hence, 2 131/200 is the decimal mixed number in its most basic form.
what is decimal?The decimal number system is frequently used to express both integer and non-integer quantities. Non-integer values have been added to the Hindu-Arabic numeral system. The technique used to represent numbers in the decimal system is known as decimal notation. A decimal number consists of both a whole number and a fractional number. The numerical value of complete and partially whole quantities is expressed using decimal numbers, which are in between integers. The full number and the fractional part of a decimal number are separated by a decimal point. The decimal point is the little dot that appears between whole numbers and fractions. An example of a decimal number is 25.5.
We must separate the whole number and fraction components of 2.655 in order to change it into a mixed number. The integer portion of the decimal, which is 2 in this instance, represents the full number.
We take the total number and divide it by the decimal to determine the fractional portion.
2.655 - 2 = 0.655
The combined number is therefore 2 and 655/1000.
By dividing the numerator and denominator by their largest common factor, we may reduce the fraction to its simplest form and so make it easier to understand. The highest common factor between 655 and 1000 in this instance is 5.
655 ÷ 5 = 131
1000 ÷ 5 = 200
Hence, 2 131/200 is the mixed number in its most basic form.

bag. You randomly choose a piece of paper from the bag.
a. What is the probability that you choose an N?
b. What is the probability that you choose an A?
c. What is the probability that you choose an E?
Answer:
A maybe
Step-by-step explanation: sorry if wrong
a. There are three N's in PENNSYLVANIA. The probability of choosing an N can be calculated as follows:
Probability of choosing an N = (Number of N's in the word) / (Total number of letters in the word)
Probability of choosing an N = 3 / 12
Probability of choosing an N = 1 / 4
Therefore, the probability of choosing an N is 1/4.
b. There are two A's in PENNSYLVANIA. The probability of choosing an A can be calculated as follows:
Probability of choosing an A = (Number of A's in the word) / (Total number of letters in the word)
Probability of choosing an A = 2 / 12
Probability of choosing an A = 1 / 6
Therefore, the probability of choosing an A is 1/6.
c. There is only one E in PENNSYLVANIA. The probability of choosing an E can be calculated as follows:
Probability of choosing an E = (Number of E's in the word) / (Total number of letters in the word)
Probability of choosing an E = 1 / 12
Therefore, the probability of choosing an E is 1/12.
Two vessels are pulling a broken-down ship toward a boathouse with forces of 750lb and 630lb. The angle between the forces is 34.5°. Determine the magnitude of the equilibrant force.
The magnitude of the equilibrant force is 938.893 lb
How to find the equilibrant forceWe can use the concept of vector addition to solve this problem. The equilibrant force is the force that is needed to balance out the two given forces, so that the net force on the broken-down ship is zero.
Let's represent the two given forces as vectors A and B, with magnitudes of 750 lb and 630 lb, respectively. The angle between them is 34.5 degrees.
|C|^2 = |A|^2 + |B|^2 - 2|A||B|cosθ
where
θ is the angle between the two forces.
Substituting the given values, we get:
|C|^2 = (750 lb)^2 + (630 lb)^2 - 2(750 lb)(630 lb)cos(34.5°)
Simplifying this expression, we get:
|C|^2 = 562500 + 396900 - 945000 * cos(34.5°)
|C|^2 = 881520.0752
Taking the square root of both sides, we get:

The graph of f ( x ) = − 1 /2 ( 1 /2 ) ^x − 3 + 5 is shifted downwards 5 units, and then shifted left 3 units, stretched vertically by a factor of 4 , and then reflected about the x -axis. a . What is the equation of the new function, g ( x ) ? g ( x ) = b . What is the y -intercept? ( , ) c . What is the domain? d . What is the range?
Answer: a. To shift the graph of f(x) downward 5 units, we subtract 5 from the function: f(x) - 5. To shift it left 3 units, we replace x with x + 3: f(x + 3) - 5. To stretch it vertically by a factor of 4, we multiply the entire function by 4: 4[f(x + 3) - 5]. Finally, to reflect it about the x-axis, we take the negative of the function: -4[f(x + 3) - 5]. Therefore, the equation of the new function g(x) is:
g(x) = -4[1/2^(x+3) - 5]
b. To find the y-intercept, we set x = 0 in the equation of g(x):
g(0) = -4[1/2^(0+3) - 5] = -4[1/8 - 5] = -4[-39/8] = 195/2
Therefore, the y-intercept is (0, 195/2).
c. The domain of g(x) is all real numbers, since there are no restrictions on x.
d. To find the range of g(x), we first observe that the function is decreasing and asymptotic to y = -5 as x approaches infinity. This means that the range of g(x) is all real numbers less than or equal to -5.

describe how a graph would look for the solution set for the inequality in problem 5. describe what the solution means and how the price of the balloons bought will affect the amount in the budget.
A)
i) the inequality to show the number of ballons that the dance committee can buy is: 0.80b + 65 ≤ 125
ii) solving the inequality above, we arrive at b ≤ 75
B) The graph is attached accordingly.
C) See the description of the solution below.
Let's start by defining our variables. Let b be the number of balloons that the dance committee could buy.
The cost of b balloons is $0.80b. We want to make sure that the cost of the balloons plus the amount already spent on decorations ($65) is less than or equal to the budget of $125. So we can write the following inequality:
0.80b + 65 ≤ 125
Now we can solve for b:
0.80b + 65 ≤ 125
0.80b ≤ 125 - 65
0.80b ≤ 60
b ≤ 75
Therefore, the dance committee can buy up to 75 balloons to stay within their budget.
To graph the solution set, we can plot b on the horizontal axis and shade the region to the left of b = 75, since b must be less than or equal to 75.
The solution set represents all possible values of b that satisfy the inequality. In this case, the solution set is b ≤ 75, which means that the dance committee can buy up to 75 balloons and still stay within their budget.
As the number of balloons increases, the cost of the balloons also increases, and the amount of money left in the budget decreases.
Therefore, the more balloons the dance committee buys, the less money they will have left for other decorations or expenses.

What is the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5
Answer:
the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30 = 8 and 39/40.
Step-by-step explanation:
To find the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5, we need to first add the two summands:
4 and 2/3 + 5 and 2/5
To add these mixed numbers, we first need to find a common denominator. The least common multiple of 3 and 5 is 15.
4 and 2/3 can be written as an improper fraction with denominator 3:
4 and 2/3 = 4 x 3/3 + 2/3 = 12/3 + 2/3 = 14/3
5 and 2/5 can be written as an improper fraction with denominator 5:
5 and 2/5 = 5 x 5/5 + 2/5 = 25/5 + 2/5 = 27/5
Now we can add the two fractions with a common denominator of 15:
14/3 + 27/5 = (14 x 5)/(3 x 5) + (27 x 3)/(5 x 3) = 70/15 + 81/15 = 151/15
So, the sum of 4 and 2/3 and 5 and 2/5 is 151/15.
Now we can subtract 1 and 1/2 from this sum:
151/15 - 1 1/2
To subtract mixed numbers, we first need to convert 1 and 1/2 to an improper fraction:
1 and 1/2 = 1 x 2/2 + 1/2 = 2/2 + 1/2 = 3/2
Now we can subtract the fractions with a common denominator of 15:
151/15 - 3/2 = (151 x 2)/(15 x 2) - (3 x 15)/(2 x 15) = 302/30 - 45/30 = 257/30
Therefore, the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30.
15. The equation of a circle is x² + y2 = 64. A point on the circle has coordinates (x. √28). Determine the possible
values of x. You must show work to receive credit.
Answer:
±6
Step-by-step explanation:
To find the possible values of x for a point on the circle with equation x² + y² = 64, we can substitute the given y-coordinate of √28 into the equation and solve for x:
x² + (√28)² = 64
x² + 28 = 64
x² = 64 - 28
x² = 36
Taking the square root of both sides, we get:
x = ±6
Therefore, the possible values of x for a point on the circle with coordinates (x, √28) are x = 6 and x = -6.

Megan flies a drone in a circular path around an object that is 180 feet west and 180 feet north of her position. The drone's path takes it over a point that is 220 feet east and 230 feet south of her.
Find an equation for the drone's path. (Assume Megan is located at the origin, with the horizontal axis running east-west and the vertical axis running north-south)
The drone's path follows the equation __________
When the drone passes due north of Megan's position, it will be ___________ feet north of her (round your answer to three decimal places).
To find the equation of the drone's path, we can first find the coordinates of the center of the circle that the drone is flying around. We can do this by finding the midpoint between the two points the drone passes over:
Midpoint in the x-direction: (220 ft - 180 ft)/2 = 20 ft to the right of the origin.
Midpoint in the y-direction: (230 ft - 180 ft)/2 = 25 ft above the origin.
Therefore, the center of the circle is located at (20, 25) ft.
The radius of the circle can be found by calculating the distance between the center of the circle and either of the two points the drone passes over:
Radius: sqrt((20-(-180))^2 + (25-180)^2) = sqrt(40000 + 15625) = 205 ft (rounded to the nearest whole number)
So the equation for the drone's path is:
(x - 20)^2 + (y - 25)^2 = 205^2
To find how far north of Megan's position the drone is when it passes due north, we can substitute x = 0 into the equation:
(0 - 20)^2 + (y - 25)^2 = 205^2
400 + (y - 25)^2 = 42025
(y - 25)^2 = 41625
y - 25 = +/-sqrt(41625)
y = 25 +/- 204.06
So the drone is either 229.06 ft north or 22.94 ft south of Megan's position when it passes due north. Rounded to three decimal places, the answer is 229.06 ft north.
A driver was fined for speeding in 100km/h zone driving 14km in 7m
Calculate the average speed of the car
Answer:
120km/h
Step-by-step explanation:
Distance=14km
Time =7m
A driver was fined for speeding in 100km/h
∴ we convert time into hours
Time =(7/60)h
Average speed of the car = total distance ÷total time

Given f(x) = 2x2 + 9x − 1 and g(x) = −x − 4, identify g(f(−3)).
Answer:
g(f(-3)) = 6.
Step-by-step explanation:
To obtain the value of f(-3), we must first determine g(f(-3)), which requires changing x in the expression for f(x) to -3:
f(x) = 2x^2 + 9x - 1
f(-3) = 2(-3)^2 + 9(-3) (-3) - 1\s= 2(9) (9) - 27 - 1\s= 18 - 27 - 1\s= -10
Knowing that f(-3) = -10 allows us to replace it in the expression for g(x):
g(x) = -x - 4
g(f(-3)) = g(-10) (-10)
Now, if we replace x in g(x) with -10, we obtain:
g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6
Hence, g(f(-3)) = 6.
Answer:
g(f(-3))=6
Step-by-step explanation:
To calculate g(f(-3)), we must first determine the value of f(-3), and then we must insert that value into g(x) to obtain the result.
By adding x = -3 to the formula for f(x), we may obtain f(-3).
f(-3) = 2(-3)
² + 9(-3) - 1
f(-3) = 2(9) - 27 - 1
f(-3) = 18 - 28
f(-3) = -10
Knowing that f(-3) = -10 allows us to replace it in the formula for g(x):
g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6
Hence, g(f(-3)) = 6.

Reread "Nothing Gold Can Stay."
Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.
Which words best help the poet convey a mood of thoughtfulness and sadness?
Question 4 options:
hardest hue to hold
early leaf's a flower
first green is gold
only so an hour
The phrase "hardest colour to hold" from Robert Frost's poem "Nothing Gold Can Stay," is the line that the poet uses to best encapsulate his thoughtfulness and sadness. The Option A is correct
What is meant by the phrase "hardest colour to hold"?These lines convey a message that goodness and beauty are transient and challenging to cling onto. As the reader considers the fleeting nature of life and the transitory nature of the things we hold dear, this concept may cause them to feel melancholy and reflective.
Although phrases such as "just so an hour," "early leaf's a flower," and "first green is gold" also emphasized an impermanence and fleetingness, but the phrase "hardest colour to hold" makes this point the most strongly.

It took 57 liters of water to fill a small swimming pool. There are approximately 3.8 liters in 1 gallon. Which measurement is closest to the number of gallons of water it took to fill the swimming pool?
A: 14 Gallons
B: 10 Gallons
C: 16 Gallons
D: 15 Gallons
The correct option is (D) i.e. It took 15 gallons of water to fill the swimming pool.
What is Measurement?
Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, volume, and many others. It is used to quantify and describe the properties of objects and phenomena in the natural world, as well as in many fields of science, engineering, commerce, and everyday life.
Measurements are typically made using standard units, such as meters for length, kilograms for mass, seconds for time, and so on.
We are given that, there are 3.8 liters in 1 gallon.
So, we can say that,
1 gallon = 3.8 liters
Now, It took 57 liters of water to fill a small swimming pool
we can convert it into gallons as follows:
1 gallon = 3.8 liters
1 / 3.8 gallon = 1 liter
57 / 3.8 gallon = 57 liters
So, 57 liters = 15 gallons of water.
Hence, (d) is the correct option.

Which of the following equations is the best model for a line of fit for the data?
ŷ = −1.34x + 21.5
ŷ = 1.34x + 21.5
ŷ = −0.75x + 17
ŷ = 0.75x + 17
The correct option is (a) ŷ = -1.34x+21.5 , that is the best model to fit the scatter plot.
What is Scatter plot?A scatter plot (or scatter chart, scatter graph) uses dots to represent values for two(2) different numeric variables. The position of each dot on horizontal and vertical axis indicates values for an individual data point.
The model of the equation best for the plot is,
ŷ = -1.34x+21.5
At point (1,20),
ŷ = -1.34x+21.5
20 = (-1.34 × 1) + 21.5
20 ≈ 20.15
At point (3,19),
ŷ = -1.34x+21.5
19 = (-1.34 × 3) + 21.5
19 ≈17.45
At point (5,15),
ŷ = -1.34x+21.5
15 = (-1.34 × 5) + 21.5
15 ≈ 14.75
The model ŷ = -1.34x+21.5 is giving the best estimation.

What is In 5 + ln 7 + 2ln 6
Answer: The answer to this equation is In (252) + 5.
Step-by-step explanation:
To solve this equation, you will need to first apply the logarithm power identity.
Now evaluate the exponent.
5 + In (7) + In (6^2)
5 + In (7) + In (36)
Apply the logarithm power identity again to the rest of this equation.
5 + In (7) + In (36)
5 + In (7 x 36)
After that, simplify the expression.
-Multiply the numbers & rearrange the terms
5 + In(7 x 36)
In(252) + 5
Therefore, your answer for this equation would be In(252) + 5.

A town's population is currently 20,000. If the population doubles every 34 years, what will
the population be 68 years from now?
Answer:
Here, given
present population = 20000
according to question,
population gets double every 34 years
i.e P = 20000 × 2
= 40000
now,
P = 40000
T = 68-34 = 34
ie, again p is double
so, P = 40000×2
= 80000
Hence, the population after 68 years from now is 80000
