We know that

[the volume of the stack of books]=[area of each book]*[<span>height of the stack]
</span>area of each book=63 in²
height of the stack=15.75 in
<span>so
</span>[the volume of the stack of books]=[63 in²]*[15.75 in]=992.25 in³<span>

the answer is 
</span>D) 992.25 in³

Answer:

992.25

Step-by-step explanation:

Each rectangular book represents a cross-section of the stack. Using Cavalieri's Principle, the area of a cross-section times the height equals the volume.

V = 63 in2 x 15. 75 in

V = 992.25 in3

Work out 1/2 x 7 giving your answer as a mixed number
irga5000 [103]

Answer:

4\frac{1}{2}

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»»  \frac{1}{2} of 7  <u>OR</u>  7 ÷ 2

So, just solve using either one and you’ll get 4.5 or 4\frac{1}{2}. But since the question wants the answer to be a mixed number, then choose 4\frac{1}{2}.

Hope this helps! :)

jemboy wants to make his 8 meter square pool into a rectangular one by increasing its length by 2m and decreasing its width by 2
mel-nik [20]
Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
 here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
            8^(2) - 2^(2) 
            = 60
