Question:
The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab
Answer:
Step-by-step explanation:
Given
Required
Determine the height
Area is calculated as:
Make Length the subject
Apply law of indices
7
If m was 1, then it would be
4 +8 = 36, which is not true.
If m was 7, then it would be
28 + 8 = 36, which is true.
If m was 11, then it would be
44 + 8 = 36, which is not true.
If m was 36, then it would be
144 + 8 = 36, which is not true.
Hope that helps!
Ans: $19,793
Compound interest:
A = P(1+6/100)²⁵
= 4100(1+0.065)²⁵
=19,793
D. V = 42 x 6
Volume is length*width*height:
V = lwh
= 6*3*14
= 3*14 *6
= 42*6
