Answer:
7 bottles
Step-by-step explanation:
first, calculate the volume of the total ammount of soloution
750ml + 9(750ml)=7500ml
then divide by 1000 to put the total into litres
7500/1000=7.5L
7.5L goes into 1L exactly 7 times with a remainder of 500ml as the bottles are required to be completely full
) A computer program found that the line LaTeX: c=2t-89c = 2 t − 89 is a good fit for the data. Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees. We predict she will sell 40 cups of lemonade.
Answer:
Number of cups of lemonade = 59 cups
Step-by-step explanation:
Given the linear function :
C = 2t - 89
At temperature of 74° ;
The cups of lemonade as calculated using the linear model:
C = 2t - 89 ; where c = cost of lemonade ; t = temperature.
C = 2(74) - 89
C = 148 - 89
C = 59
A function assigns the values. The prediction that she will sell 40 cups of lemonade that day is wrong.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given that function, c=2t-89, where the number of cups of lemonade is represented by c, and t represents the temperature of the day.
Now, as it is given that the temperature at the day is 74, therefore, the number of cups that will be sold that day can be predicted as,
[tex]c = 2t-89\\\\c = 2(74)-89\\\\c = 148-89\\\\c = 59[/tex]
Hence, the prediction that she will sell 40 cups of lemonade that day is wrong.

Imagine you measure the length of 15 cars, and then sum that length, in order to see how big a parking lot must be. You do this in two different ways. First, you use the same bad tape measure for each car so that your measurement is always 1 cm too long, or always too short, for all of the measurements. For your second attempt, you use a different bad tape measure for each car, so there is an uncertainty of plus or minus 1cm in each measurement. What is your estimate of the total error in the sum of all the car lengths in these two cases
Answer:
± 15 cm
Step-by-step explanation:
In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.
In the second case, the uncertainty or error is also ± 1 cm.
Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm
So, the total error in both cases is ± 15 cm.

Four friends shared 7 chocolate bars. Each of them was given an equal share of the chocolate bars. How many chocolate bars did each person get?
A: 4/7
B : 6/8
C: 1 1/4
D: 1 3/4
We are given:
There were 7 chocolate bars, evenly shared between 4 friends
Number of Bars one person will get:
Number of bars one person will get = Number of Bars / Number of Friends
Number of Bars = 7 / 4
but since this number does NOT match any of the given options, we will convert it to a mixed fraction
The number of bars one person will get will be [tex]1\frac{3}{4}[/tex], written as a mixed fraction.
Therefore, the correct answer is option D
Answer:
4 friends =7 chocolate

The graph of y = 4x2 - 4x – 1 is show
Use the graph to find estimates for
the solutions of
i) 4x2 - 4x – 1 = 0
Answer:
Here we have the equation:
y = 4*x^2 - 4*x - 1
And we should have the graph (you can see it below this answer)
Now we want to find the solutions of:
4*x^2 - 4*x - 1 = 0
These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.
Then we need to find the two values of x at which our graph intersects the x-axis.
In the graph, we can estimate the solutions as:
x = -0.2
x = 1.2
To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:
[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*4*(-1)} }{2*4} = \frac{4+ -\sqrt{32} }{8} = \frac{4 +-5.66}{8}[/tex]
Then the two solutions are:
x = (4 + 5.66)/8 = 11.2075
x = (4 - 5.66)/8 = -0.2075

2. using the previous item it is possible to write the next equation:
5(x+20)=4*20+10*x; ⇒ x=4.
3. the required mass is 4 pounds.

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
