81
Explanation:
A perfect square has lengths that are all the same, so if one side is 9 the other sides must be 9. Then using the formula to find area (A=LxW) we can multiply 9 x 9 to get a area of 81.
A=9x9
A=81

Answer:
4. x = 50
5. x = 5
Step-by-step explanation:
For question 4:
Multiply both sides: x + 35 = -15Move the constant to the right: x = -15 - 35Calculate: x = -50For question 5:
Move the constant to the right: -3x = -17 + 2Calculate the sum: -3x = -15Divide both sides: x = 5Answer:
4) x= -50
5) x= 5
Step-by-step explanation:
Number 5
Simplifying
-3x + -2 = -17
Reorder the terms:
-2 + -3x = -17
Solving
-2 + -3x = -17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -3x = -17 + 2
Combine like terms: -2 + 2 = 0
0 + -3x = -17 + 2
-3x = -17 + 2
Combine like terms: -17 + 2 = -15
-3x = -15
Divide each side by '-3'.
x = 5
Simplifying
x = 5
Number 4

Mia has applied to be a lifeguard for the summer. The lifeguard job is three days a week with hours and
the table below.
Hours worked
Amount paid
Tuesday

Thursday
8
$70,00
Saturday
5
$43.75
Which statement best describes the hourly rates?
O The two jobs pay the same hourly rate.
The comparison cannot be made with the information given.
O Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Jason's camp counselor job pays a lower hourly rate than Mia's lifeguard job.
Answers
Answer:
The correct statement is (3).
Step-by-step explanation:
Jason's hourly pay rate as a camp counselor for the summer is:
J = $9 / hour.
The table representing Mia's pay as a lifeguard for the summer is as follows:
Days Hours worked Amount paid
Tuesday 6 $52.50
Thursday 8 $70,00
Saturday 5 $43.75
Compute Mia's hourly rate for Tuesday: [tex]\frac{\$52.50}{6}=\$8.75[/tex]
Compute Mia's hourly rate for Thursday : [tex]\frac{\$70.00}{8}=\$8.75[/tex]
Compute Mia's hourly rate for Saturday: [tex]\frac{\$43.75}{5}=\$8.75[/tex]
Thus, Mia's hourly rate as a lifeguard for the summer is,
M = $8.75 / hour
This implies that Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Thus, the correct statement is (3).
Answer:
The answer is C because if u multiply 6 by 9 its 54 that's how much Jason gets for 6 hours while on the other hand Mia for six hours gets 52 dollars.

What is the area of a square in terms of x & y, if one side is 2x-y?
Answers
Answer: (2x-y)^2
Step-by-step explanation:
The area of a square is given by the formula A = s^2.
We know that the length of one side is s = 2x-y. We can substitute this into our area equation:
A = (2x-y)^2
If you need to multiply out the answer:
A = (2x-y)(2x-y)
A = 4x^2-4xy+y^2

The area of the football field is 57,600 square feet. If the width of the field is 4/9 the length,what is the length of the football field ?
Answers
Answer:
360 feet.
Step-by-step explanation:
Let x = length, then the width is 4x/9 feet.
So we have the equation:
x * 4x/9 = 57600
4x^2 / 9 = 57600
4x^2 = 57600 * 9
x^2 = 57600 * 9 / 4
x = √57600 * 3 / 2
x = 240* 3/2
x = 360 feet.

Answer:
$640
Step-by-step explanation:
512/0.2 = 2560 quarters
2560 quarters = 640 US Dollars
Hope this helps !
The total amount that was stolen is 640 US dollars.
How to determine the total amount that was stolen?The weight of the amount is given by;
Weight = 512 ounces
The weight of each quarter will be;
Unit weight = 0.2 ounces
So, the total amount would be;
Total = 512/0.2
Evaluate;
The Total amount = 2560 quarters
1 quarter = $0.25
So, we have:
The Total amount = $0.25 * 2560
Now Evaluate the product
The Total amount = $640
Hence, the total amount that was stolen is 640 US dollars.

Which equation can be used to model the relationship between the number of greenhouses outfitted depending on the number of years since the project began?
Answers
Answer:
Should be something along the lines of:
3,450 = 326x - 310
Step-by-step explanation:
First, let's start with the number of years. Assume the number of years is x. 3262 greenhouses amounts to about 326 greehouses/year. The other number was the existing greenhouses, but we want just how many greenhouses that were built, per the subtraction sign.
