Answer:
Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
Step-by-step explanation:
Given:
Radius of the Earth = 3,960 miles
Find:
Surface area of Torrid Zone (cylinder shape) = ?
Computation:
We know that, distance between two tropics is 3,250 miles.
So, Height = 3,250 miles
Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
Answer:
The 2nd, 3rd and last ones work.
Step-by-step explanation:
-27÷9 is -3. Positive no. ÷ Negative no. = Negative number
So you now need to find which of the answers have -3 as the answer.
The first one won't work since it's answer will be positive.
18/-6= -3 so this works.
The next one won't work since it's quotient will be a positive number.
27/-9 = -3 this also works.
The next one won't work since it's quotient will also be a posititve number.
-9/3 = -3 this also works.
Hope this helps:)

Step-by-step explanation:
An equation is formed of two equal expressions. The cost of a new book is $7.43, while the cost of an old book is $8.86.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the cost of 14 used books is $124. Therefore, the cost of a single used book is,
Cost of single used book(u) = 124/14 = $8.86
Also, the cost of 12 used books and 4 new books is $136. Therefore, the equation can be written as,
12u + 4n = 136
12(8.85) + 4n = 136
106.2 + 4n = 136
n = $7.43
Hence, the cost of a new book is $7.43, while the cost of an old book is $8.86.

Hi there,
9. Which of the following is the value of x in the solution to the
system of equations given below?
8 + 2x = 5y (1)
4x - y = 2 (2)
▪ (1)
y = ( 8 + 2x ) ÷ 5
▪ (2)
4x - [( 8 + 2x ) ÷ 5] = 2
( 20x - 8 - 2x ) ÷ 5 = 2
20x - 8 - 2x = 2 × 5
20x - 2x = ( 2 × 5 ) + 8
18x = 10 + 8
18x = 18
x = 18 ÷ 18
x = 1
The answer is : A. 1
