14.59
To solve, simply plug -7.1 into -Z. Since Z is negative in the equation, it will turn the Z that’s given to us into a negative. Since that Z is already negative, it will now become a positive since that’s what two negatives being multiplied make. This is what your problem will look like:
-(-7.1) + 7.49
7.1 + 7.49 = 14.59

Answer:
The rate of decrease is: 
Step-by-step explanation:
Given

---- We used minus because the rate is decreasing
Required
Rate of decrease when: 
The volume of the cube is:

Differentiate

Make dV the subject

Divide both sides by dt

Given that:
and 



<em>Hence, the rate of decrease is: 43.2mm^3/min</em>
Answer:
x/100 x 8 = 6
8x/100 = 6
x100 x100
8x = 600
Divide by 8 on both sides:
X = 75
Consider a percent out of 100. 'Of' meaning multiplication. 'is' meaning equal to that number.
(unknown number/percent)x/100 x 8(of 8) = 6(is 6)
