Answer:
(9/8)^-1 = 8/9
Step-by-step explanation:
To re write without an exponent means we will eliminate it's power.
This fraction came with the power of -1.
And when the power of a fraction or a whole number comes with power of -1 what it simply means it's the inverse of the number.
So let's evaluate the above fraction.
(9/8)^-1 = 1/(9/8)
(9/8)^-1 = 1*(8/9)
(9/8)^-1 = 8/9
I know it’s A. But not sure about the fraction part I’ll solve it later for you
Answer:
-10 2/3
Step-by-step explanation:
-8 x 4
_______ = -32/3 simplified to -10 2/3
3 x 1
Answer:
The least amount of dimensions would be using a 4ft x 4ft base.
Step-by-step explanation:
When looking to maximize area and minimize materials, a perfect square always does this. To prove the point, consider the 4 x 4 box in the answer to say a 16 x 1 box, which would have the same area.
The 4 x 4 box would have 4 sides each of 4 ft. Therefore, it would have 16 feet of sides to construct.
Meanwhile, there would be two sides on the other one that were 16 ft alone.
