Answer: 7.25
Step-by-step explanation:
436% × ? = 31.61
31.61 ÷ 436% =
31.61 ÷ (436 ÷ 100) =
(100 × 31.61) ÷ 436 =
3,161 ÷ 436 =

An acre is a surface measure, used in agriculture in several countries.
According to the country and the time, it is equivalent to several surfaces.
We will use the following conversion:
1 acre = 43560 feet ^ 2
Thus:
40 acre = 1,742,400 feet ^ 2
The area of the rectangle is:
1,742,400 = (1,200) * (x)
Clearing the other dimension we have:
x = (1742400) / (1200)
x = 1452 feet
Answer:
He needs 1452 feet of fence.
For the two figures to be similar, the missing length must be 30.
<h3 /><h3>What is the missing length?</h3>
For the two figures to be similar, the dimension of each figures must be proportional to each other.
Let the missing length be x.
Hence,
x/25 = 24/20
We cross multiply
x × 20 = 24 × 25
x × 20 = 600
x = 600/20
x = 30
Therefore, for the two figures to be similar, the missing length must be 30.

Answer:
17)-3,0,3
18)-9,-3,9
19)-6, -3, 1, 3
20) -9, -5, -1, 0
21) -4, -3, -2, -1,0
22)-15, -10, -5, 10
Step-by-step explanation:
if your getting confused, just imagine a number line in your head or write one on your paper, that has negative numbers on the left side and positive numbers on the right side
(ex: ....-3, -2, -1, 0, 1, 2, 3....)
remember that the number that is in the left side is always less than the the number on the right side, meaning the number on the right side of the number line is greater than the number on the left side.
