Area of a Square: A = x²Step-by-step explanation:
Step 1: Define
Side length = 5 in
Step 2: Solve for A
Substitute: A = (5 in)²Evaluate: A = 25 in²And we have our final answer!
Answer:
25 inches squared.
Step-by-step explanation:
Since we know a square has 4 sides of equal length, and one of the sides has been given to us (5 inches), it's safe to assume the rest of the sides are the same. To find the area, we multiply length x width (5 x 5) to get 25 inches squared. Hope this helps! xx

If Amerie earn $120 in interest in 5 years on money that was invested at 6%, find the original principal.
Answer:
Original principal = 400
Step-by-step explanation:
Given:
Interest amount = $120
Rate = 6%
Time = 5 years
Find:
Original principal
Computation:
Interest amount = Original principal x Rate x Time
120 = Original principal x 6% x 5
Original principal = 400

Answer:
8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.
9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.
10. For A: y = (1/4)x
For B: y = (2/5)x
11. For A: 3 miles
For B: (24/5) miles, or 4 and (4/5) miles.
12. Can't see the entire problem sorry.
Step-by-step explanation:
9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.
10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.
11. x represents the time, so just substitute x as 12 in the equation.
For a concert 5,000 tickets were sold, and the proceeds were $72,000. Tickets for children 16 and younger were $10, adults were $20, and seniors 60 and older were $15. There were 3 times more children than seniors at the concert. What system of equations represents the number of children, c, adults, a, and seniors, s, that attended the concert?
Answer:
The answer is:
[tex]( c + a + s) = 5000\\\\(10c + 20a + 15s) = 72000\\\\c = 3s[/tex]
Step-by-step explanation:
Ticket number sold = 5000
Ticket revenue Selling = 72,000 dollars
Kids 16 and younger tickets = $10
adults=$20
senior citizens= 60
Old = $15
Let:
Children's number, c ;
Ownership, a;
The aged, s,
Also at the event, there were 3 times many more kids as the senior citizens; c=3 total amount attendees= 5000
5,000= (c + a + s)
Total wages or income
72000= (10c + 20a + 15s)
The equation r = 4sin(θ) represents a circle. What is the radius of the circle, and what is the symmetry of the graph?
Answer:
The radius is 2 units, and the graph is symmetric about the line Theta = StartFraction pi Over 2 EndFraction. Its A
Step-by-step explanation:
Which equation is equivalent to 7-2(3x+4)=8x
A -6x+15=8x
B-6x-1=8x
C15x+20=8x
The equation that is equivalent to the expression 7-2(3x+4)=8x is
-6x - 1 = 8x.
Option B is the correct answer.
We have,
To find the equation that is equivalent to 7-2(3x+4)=8x, simplify the given equation by applying the distributive property and combining like terms.
7 - 2(3x + 4) = 8x
First, distribute the -2 to the terms inside the parentheses:
7 - 6x - 8 = 8x
Combine like terms:
-6x - 1 = 8x
Thus,
The equation that is equivalent to the expression 7-2(3x+4)=8x is
-6x - 1 = 8x.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 4 to 5. If there were 4160 no votes, what was the total number of votes?
Answer:
The total number of voters was 7488
Step-by-step explanation:
Let us solve this question using the ratio method
∵ The ratio of yes votes to no votes was 4 to 5
∵ There were 4160 no votes
∵ We need to find the total number of votes
∵ The total of the ratio = 4 + 5 = 9
→ By using the ratio method
→ YES : NO : Total
→ 4 : 5 : 9
→ x : 4160 : y
→ By using the cross multiplication
∵ 5 × y = 4160 × 9
∴ 5y = 37440
→ Divide both sides by 5 to find y
∵ [tex]\frac{5y}{5}[/tex] = [tex]\frac{37440}{5}[/tex]
∴ y = 7488
∵ y represents the total number of voters
∴ The total number of voters was 7488

Cesar, Carlos, David, and Edwin decided to have a push-up contest. The following table describes the push-up speeds of the four boys. Which boy has the fastest speed?
Answer:
Edwin (55 push-ups per minute)
Step-by-step explanation:
We need to find the actual number of pushups per one minute in order to compare them on the same base (per ONE minute). So we do"
Cesar: 200 / 4 = 50 pu/min
Carlos: 240 / 5 = 48 pu/min
David: 150 / 3 = 50 pu/min
Edwin: 110 / 2 = 55 pu/min
Therefore, Edwin is the fastest since he does more pushups per minute.
