A direct variation is a proportional equation. Such as:

For every 3 cookies, linda gets 1 glass of milk. The equation for this is y=3x where y is the glasses and x is the cookies. this is a direct variation. It also has a linear line. Linear means straight. Rate of change and slope are the exact same thing. They are the value of 'm' in y=mx+b

What is the volume of the prism

Scilla [17]

Hey there :)

We know the volume formula of triangular prism
Volume = base x height of prism
= $\frac{1}{2} (base)(height)(height of prism)$

We are given:
The base = 8 in
The height = 15 in
You do not need the 17 in ( it is there to trick you )
The height of the prism = 10 in

Apply the formula,
V = $\frac{1}{2} (8)(15)(10)$
= 600 in³

Your final answer will be the last option

A spherical water tank holds 7,500 ft3 of water. What is the diameter of the tank?

Alisiya [41]

Answer: 2r=d

d=24.28590063

Step-by-step explanation:

vsphere=4/3pir^3

7500=4/3pir^3

times both sides by 3

22500=4pir^3

divide both sides by 4

5625=pir^3

divide bot sides by pi

1790.4931=r^3

cube root both sides

12.142950=r

2r=d

d=24.28590063 ft
