Answer:

The missing volume of gas is 6 liters

Step-by-step explanation:

The following data points represent the volume  of gas in each race car driver's tank (in liters):

4,5, 13, ?

Let the missing value be x

Data : 4,5,13,x

Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}

7 = \frac{4+5+13+x}{4}

7 \times 4=4+5+13+x

28=22+x

28-22=x

6=x

Hence The missing volume of gas is 6 liters

yKpoI14uk [10]
Let x represent the amount of money Sophia can spend on party favors. 

x = amount of money Sophia can spend 
$2.75 = amount spent per person
6 = amount of people

Equation:- 

x ÷ $2.75 = 6

Now lets solve for x :-
To solve for x we will use d INVERSE OPERATION of division which is multiplication. Lets do it:-

x ÷ 2.75 = 6
6 × 2.75 = x
6 × 2.75 = 16.50
x = 16.50 

CHECK OUR WORK:-

x ÷ 2.75 = 6
x = 16.50
16.50 ÷ 2.75 = 6
We were RIGHT!!

So, our equation for dis question would be x ÷ 2.75 = 6. When we solve for x, x = 16.50. Sophia can spend $16.50 on her party favors for 6 people. 

Hope I helped ya!! xD

Find the perimeter of this shape<br>​
Margaret [11]
The answer is 257.08m. Explanation: you know that one side of the square in the middle is 50m. This is the same as the diameter of one of the half circles on each side. The perimeter of a circle is the formula C=2(pi)r, where r is the radius. Dividing 50 by two will get you the size of the radius, then just plug it into the equation to find the perimeter of both rounded sides (a full circle). The two circular sides equal 157.08m, so then you just need to add the flat sides, which are both 50m since they’re congruent. 157.08m + 50m + 50m = 257.08m, so the perimeter of the shape is 257.08m.

What is the rate of change of the linear relationship modeled in the table?
Lisa [10]
The correct answer is 3/2.

Slope = Rate Of Change 

Slope Formula:        y₂ - y₁          5 - 2         3
                               -------------- = ---------- = -----
                                   x₂ - x₁          3 - 1         2

I hope that this helps you!

Btw, ₁ and ₂ are subscripts, they do not have anything to do with the actual working of the problem.
