5. <span>15' x 15' x </span>9' = 2025 Cubic Feet<span>. so its 15
6. 1.5 * 2.5 = 3.75; 3.75 * 3 = 11.25 so it 3.75*3
7.Really the only thing that can help you is plunging in the formula

Answer:

Step-by-step explanation:
We know from the graph

and

using the given equation we can solve

subtract 1 from both sides so that k is isolated

You can take 3x as a common factor from them, then it would be:
3x (5+8a) ......so, it's the equivalent form of that...
75 1/3 = 75.33
75.33% = 75.33/100
= 7533/10000
not sure if it can be simplified more than this
