Answer:
H in terms of c is H = 5c³.
Step-by-step explanation:
Given that:
H = 40 and c = 2
H varies directly to the cube of c.
Which means that,
H ∝ c³
Let,
k be the proportionality constant.
H = kc³
Putting H=40 and c=2

Dividing both sides by 8,

Now,
H in terms of c.
H = 5c³
Hence,
H in terms of c is H = 5c³.
I’m pretty sure the answer is 1
1. 7x + 9 = 48
7x = 58 - 9
7x = 49
X = 7
First, find the volume of the full tank
V= 16*8.5*10.5
V=1428 cubic inches
Then, just find 3/4 of the volume
V2= 1428 * (3/4)
V2= 1071 cubic inches
