Use a^2 + b^2 = c^2 to get your answer
6^2 + b^2 =7^2
36 + b^2 = 49
b^2 = 13
b= 3.6
3.6 meters apart

Step-by-step explanation:
8)
around the tank = 12 * circumference
circumference = d![\pi](https://tex.z-dn.net/?f=%5Cpi)
c = 30![\pi](https://tex.z-dn.net/?f=%5Cpi)
c = 94.2477796
area around tank = 12 * 94.2477796 = 1130.973355
now top of tank
area of a circle = ![\pi](https://tex.z-dn.net/?f=%5Cpi)
![r^{2}](https://tex.z-dn.net/?f=r%5E%7B2%7D)
*
= 706.858347
add the two surface areas together for the total
706.858347 + 1130.973355 = 1837.832
total surface area = 1837.8 ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is
*
* 10 = 282.7 ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)

Number 7 is two
Number 8 is infinitely many.
Answer:
dogs - 13
cats - 39
Step-by-step explanation:
Let the number of dogs Ma Bernier have be represented with d
She has 3 times as many cats as dogs, the number of cats she has :
cats = 3d
The sum of the cats and dogs is 52
d + 3d = 52
4d = 52
divide both sides of the equation by 4
d = 13
She has 13 dogs
Cats = 3d
= 3 x 13 = 39
