Hey!
We're finding the permitter.
This is defined as the distance around an object, and with squares and rectangles is:
P = 2L+2W
which basically simplifies to "you're adding all the sides".
Therefore, we have:
P= 5+5+3+3 =
10 + 6 =

of the 75 boys in the 7th grade class, 25 participate in at least one sport . of the 120 girls in 7th grade class 30
hoa [83]

Answer:

"No, the relationship is NOT proportional"

Step-by-step explanation:

<u>Complete Question:</u>

Of the 75 boys in the 7th grade class, 25 participate in at least one sport. Of the 120 girls in 7th grade class 30 participate in at least one sport. Is this relationship proportional?

We have to see the ratio of each and if they are equal (after reducing), we can say they are proportional.

Boys:

25 participate in atleast 1 sport and there are total of 75. Hence, ratio is

25 : 75 = 1 : 3

Girls:

30 particiapte in atleast 1 sport and there are toal of 120. hence ratio is:

30 : 120 = 1 : 4

So, the relationship is NOT proportional

Instructions: Find the volume of each figure. Round your answers to the nearest tenth, if necessary.
Ilia_Sergeevich [38]

The volume of the cone is  84.9 km³

<h3>How to find the volume of a cone?</h3>

Volume of a cone = 1 / 3 πr²h

where

  • h = height
  • r = radius

Therefore,

radius = 3 km

height = √9.5² - 3²

height = √81.25

height = 9.01387818866

height = 9.014 km

Volume of a cone = 1 / 3 × 3.14 × 3² × 9.014

volume of the cone = 254.732197612 / 3

volume of the cone = 84.9107325372

volume of the cone = 84.9 km³

7.6x = 64
x = 64/7.6
x = <span> <span> <span> 8.4210526316 </span> </span> </span>
So, 3.05 is NOT the solution
