Area of Square Formula: A = s²
- <em>s</em> is the side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
A = 225 in²
<u>Step 2: Solve for </u><em><u>s</u></em>
- Substitute in variables [Area of a Square Formula]: s² = 225 in²
- [Equality Property] Square root both sides: s = 15 in
The William's family used the sprinklers for 59 hours.
Because it used 25L per hour so 25/1 is 25 so then you multiply 1475 by 25 and you get 59
= used sprinklers for 59 hours.
The Taylor family used the sprinklers for 73.75 hours.
Because it used 20L per hour so 20/1 is 20 then you multiply 1475 by 20 and you get 73.75
= Used sprinklers for 73.75 hours.
Find the constant of proportionality
Answer:
7/165
Step-by-step explanation:
This is a mixed recurring decimal (the zero is not repeating)
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
Now ,the denominator:
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242......
