Find the area of these triangles please! Greatly appreciated if you do.
Answer:
11. 35 ft²
12. 24 cm²
13. 18 ft²
14. 28 in²
15. 9 in²
Step-by-step explanation:
11. A= (b×h)÷2
= (10×7)÷2
= 70 ÷ 2
= 35 ft²
12. A= (b×h)÷2
= (8×6)÷2
= 48 ÷ 2
= 24 cm²
13. A=(b×h)÷2
=(9×4)÷2
= 36 ÷ 2
= 18 ft²
14. A=(b×h)÷2
=(7×8)÷2
= 56 ÷ 2
= 28 in²
15. A=(b×h)÷2
=(3×6)÷2
= 18 ÷ 2
= 9 in²
Good luck ^_^

A 6-POUND BAG OF CANDY COSTS $11.28 WHAT IS THE COST PER POUND? 10
Answer:
$1.88
Step-by-step explanation:
11.28 / 6 = 1.88
Answer: $1.88
Step-by-step explanation:
We have 6 pounds of candy that cost 11.28, and we need to find the unit rate.
If we want to find the unit rate, or the cost per pound, we can use the equation 11.28 ÷ 6.
We can then divide each side by 6, or solve the equation.
11.28 ÷ 6 = 1.88.
Therefore, the each pound of candy costs $1.88.
what is the value of 18-3 k ÷9 when k=4
Answer:
16.6666666667
Step-by-step explanation:
Answer: 50/3 or 16 2/3 or 16.67
Step-by-step explanation:
Given
18-3k÷9
Substitute [k] value into the given expression
18-3k÷9
=18-3(4)÷9 ⇒ Substitute the value
=18-12÷9 ⇒ Expand the parenthesis
=18-4/3 ⇒ First do division
=54/3-4/3 ⇒ Convert an integer into a fraction
=50/3=16 2/3=16.67

Answer:
book x 8
Step-by-step explanation:
A set of cards contains cards numbered 1 – 8. Mrs. Jacob’s class is conducting an experiment in which a card is drawn from the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?
Answer: 125
The best prediction for the number of times a 4 will be drawn from the pile is:
A set of cards contains cards numbered 1 – 8.
So, the theoretical probability that 4 comes up is:
Ratio of Number of favorable outcome( outcome of 4) to the total umber outcome(i.e. 8 )
Hence, Theoretical Probability that 4 is drawn=1/8
Now, out of 1000 trials the best prediction of number of times 4 is drawn is:
(The probability of drawing 4)×(Number of experiments or trials)
=(1/8)×1000
=125

In the diagram, each shape has a value and the sums of the shapes in each of the first three rows is given. Find the sum of the shapes in the fourth row.
Answer:
26
Step-by-step explanation:
2 squares + 3 circles = 31. So, the sum of the squares is divisible by two, and the sum of the circles is divisible by 3. Then, I used trial and error to figure out that the square's value is five, and the circle's value is seven. 5 + 7 + 7 = 19. 27 - 19 = 8. The triangle's value is eight. 5 + 7 + 12 = 24. It works. 15 + 7 + 4 = 26

Explain how you change a decimal to a fraction.
Answer:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Scores turned in by an amateur golfer at the Bonita Fairways Golf Course in Bonita Springs, Florida, during and are as follows: 2018 Season: 74 78 79 77 75 73 75 77 2019 Season: 71 70 75 77 85 80 71 79 a. Use the mean (to the nearest whole number) and standard deviation (to decimals) to evaluate the golfer's performance over the two-year period. Mean Standard deviation Mean Standard deviation b. What is the primary difference in performance between and
Answer:
Step-by-step explanation:
The mean for 2018 scores is:
[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]
[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]
[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]
[tex]\mathbf{M ean ( \overline X) = 76}[/tex]
The standard deviation for 2018 scores is:
[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]
[tex]s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1} }[/tex]
[tex]s = \sqrt{\dfrac{30}{7} }[/tex]
s = 2.07
The mean and standard deviation for the year 2018 scores is:
2018
Mean 76
Standard deviation 2.07
The mean for 2019 scores is:
[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]
[tex]M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}[/tex]
[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]
[tex]\mathbf{M ean ( \overline X) = 76}[/tex]
The standard deviation for 2019 scores is:
[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]
[tex]s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1} }[/tex]
[tex]s = \sqrt{\dfrac{194}{7} }[/tex]
s = 5.26
The mean and standard deviation for the year 2019 scores is:
2019
Mean 76
Standard deviation 5.26
Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.
Thus, the variation in scores was higher in 2019.

Answer:
Step-by-step explanation:
There are six sides, in this case they are all equal square faces.
A=6s^2, s, side length is 5.5 so
A=6(5.5)^2
A=6(30.25)
A=181.5 cm^2
Solve the equation.
-3(3n + 4) = 6
Answer:
n=-2
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(3n+4)=6
Step 1: Simplify both sides of the equation.
−3(3n+4)=6
(−3)(3n)+(−3)(4)=6(Distribute)
−9n+−12=6
−9n−12=6
Step 2: Add 12 to both sides.
−9n−12+12=6+12
−9n=18
Step 3: Divide both sides by -9.
−9n
−9
=
18
−9
n=−2
Answer:
n = -2
Step-by-step explanation:
-3(3n + 4) = 6; multiply -3 to both 3n and 4.
-9n - 12 = 6; add 12 on both sides.
-9n = 18; divide -9 on both sides to isolate the variable n.
n = -2

⅚of the number of pupils in a class is 4 greater than three-quarters of the number in the class .find the number of pupils in the class
Answer:
48 pupils
Step-by-step explanation:
let the number of people in the class be x
⅚ of the number of pupils in a class is expressed as ⅚x
4 greater than three-quarters of the number in the class is expressed as 3/4x+4
Equating both expressions
⅚x = 3/4x + 4
5x/6 - 3x/4 = 4
(10x-9x)/12 = 4
x/12 = 4
x = 4*12
x = 48
Hence the number of pupils in the class is 48 pupils
your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents left a $31.29 tip. What percent of the bill was the tip?
Answer:
[tex]\%Tip = 13.04\%[/tex]
Step-by-step explanation:
Given
[tex]Tip= \$31.29[/tex]
[tex]Bill = \$208.60[/tex]
Required
Determine the percentage of the tip
First, we calculate the amount paid
[tex]Amount = Tip + Bill[/tex]
[tex]Amount = \$31.29 + \$208.60[/tex]
[tex]Amount = \$239.89[/tex]
The percentage of the tip is then calculated using:
[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]
[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]
[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]
[tex]\%Tip = \frac{3129}{239.89} \%[/tex]
[tex]\%Tip = 13.04\%[/tex]

12. Given a right triangle with the length
of one leg equal to 9 centimeters and
the length of the hypotenuse equal to
15 centimeters, what is the length of
the other leg?
F 6 cm
H square root of 306 cm
G 12 cm
J 144 cm
Answer:
G. 12 cm
Step-by-step explanation:
Length of one leg of right triangle = a = 9 cm
Length of hypotenuse = c = 15 cm
Length of the other leg = b = ?
Applying pythagorean theorem, c² = a² + b², we have:
15² = 9² + b²
15² - 9² = b²
144 = b²
b = √144
b = 12

a train travels 16 miles in 20 minutes how many minutes would 12 miles be
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
Answer:
It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.
On a bicycle, Eddie can travel 20 miles in 4 hours. How many hours does it take Eddie to travel 1 mile?
Answer:
1 mile = 0.2 hours
Step-by-step explanation:
Given that,
Eddie can travel 20 miles in 4 hours.
We need to find how many hours does it take Eddie to travel 1 mile.
20 mile = 4 hours
1 mile = (4/20) hours
= 0.2 hours
So, to travel 1 mile will take 0.2 hours.
