49
3+4 is 7
and squared is 2
7x7=49
Answer:
Step-by-step explanation:
<em>Perimeter is the sum of side lengths</em>
<u>Let's find the sides first</u>
- AB = √(-2- 2)² + (-4+1)² = 5
- BC = (2 - (-1)) = 3
- CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
- DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
- AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32
<u>Perimeter is</u>
- P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number
Answer:
576 People
Solving:
If the total number of people that downloaded songs from the site ( 100% ) equals "x," and 60% of "x" plus 384 equals "x," 384 must be 40% of "x" to add up to 100% ( the percentage of people "x" represents ).
384 / 40% = 960 = x
x = 0.6 ( x ) + 384
960 = 0.6 ( 960 ) + 384
960 * 60% = 576 people
The answer, when rounded to the nearest tenth is 19.2
First you can get rid of the decimals by multiplying both numbers by 100, this just makes the whole problem easier. Now all that needs to be done is long division:
(In my work I didn’t realize that it said round to the nearest tenth until I had already gotten past what I needed to find)
