Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.
Answer:
Yes
Explanation: 120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.
15 ⋅ 1.2 = 18.0 = 18
15 hours ⋅ 1.2 = 18.0 hours = 18 hours
This means that Maxine is correct.
C is clicked but I'm not sure if that is the answer I just clicked one. I need the answer to both.
Answer:
I believe that B is the correct answer!
Step-by-step explanation:
The (x+5) can cancel
Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.
Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)
Lastly the (x-5) on the top and bottom will cancel resulting in result B
I hope this helped!
Answer:
B(lol the one you chose randomly was right)
5, sorry I dunno the second number...
Step-by-step explanation:
(x+5)(x+5)(x-5)/ (x+5)^2(x-5)^2
(x+5)^2 gets canceled out
(x-5)/(x-5)^2
1/x-5
MARKING BRAINLIEST PLZ HELP! You are given the following five lines:
Line 1: y=-2x + 9
Line 2: y= 1/2x + 1
Line 3: y= 2x + 2
Line 4: 6x - 3y = 6
Line 5: 4x + 2y = 4
Part A: Which two lines could be used to create a system of equations that has no solution? Explain your answer
Part B: Which two lines could be used to create a system of equations that has many solutions? Explain your answer
Part C: Which two lines could be used to create a system of equations that has one solution? Explain your answer
Part A:
lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.
Part B:
lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph
Part C:
The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.
The Graphs Are Shown Below.

Jaylen used the seat number for each of the 6,500 fans' seats in the stands at a college football game and put the numbers in a computer program. He randomly chose 200 numbers and found that 36 of those people had also purchased a parking voucher. Estimate the number of fans in the stands at a sold-out football game that purchased a parking voucher. Explain.
Answer:
1170 seats
Step-by-step explanation:
Given
[tex]Seats = 6500[/tex]
From the computer program, we have:
[tex]Sample = 200[/tex]
[tex]Voucher = 36[/tex]
First, we calculate the proportion (p) of those that bought the voucher
[tex]Proportion = \frac{Voucher}{Sample}[/tex]
[tex]p = \frac{36}{200}[/tex]
[tex]p = 0.18[/tex]
Using the larger population (i.e. 6500 seats), the esitimate of people that have bought the voucher is then calculated as:
[tex]Estimate= Proportion * Seats[/tex]
[tex]Estimate= 0.18 * 6500[/tex]
[tex]Estimate= 1170[/tex]

What is the equation of a line with slope 4 and passes through point (4,2)?
Answer:
y = 4x - 14
Step-by-step explanation:
Use point-slope form and substitute the values.
y - 2 = 4(x - 4)
y - 2 = 4x - 16
y = 4x - 14

Your fi nancial advisor recommends buying a 10-year bond with a face value of $1,000 and an annual coupon of $80. The current interest rate is 7 percent. What might you expect to pay for the bond (aside from b
Answer:
Bond Price= $1,070.24
Step-by-step explanation:
Giving the following information:
Cupon= $80
Number of periods= 10 years
Face value= $1,000
Interest rate= 7%
To calculate the price of the bond, we need to use the following formula:
Bond Price= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]
Bond Price= 80*{[1 - (1.07^-10)] / 0.07} + [1,000 / (1.07^10)]
Bond Price= 561.89 + 508.35
Bond Price= $1,070.24
Paige has scored 12 soccer goals after playing 5 games. How many games will it take for her to score 72 soccer goals?

If it's hard to see the answers are Pythagorean Theorem, rearrange the previous statement, Pythagorean Theorem, and Expand (b-x)2
Answer:
1) a2 = h2 + x2
✔ Pythagorean theorem
2) h2 = a2 - x2
✔ Rearrange the previous statement
3) c2 = h2 + (b-x)2
✔ Pythagorean theorem
4) c2 = h2 + b2 -2bx + x2
✔ Expand (b – x)2
Step-by-step explanation:
The Pythagorean Theorem could be represented mathematically as follows, Here, c represents the length of the hypotenuse (the longest side), or b or a are the lengths of the other 2 sides. From the equation, you can easily find the value of the 1 side if you have the values of the other 2
1) a2 = h2 + x2
Pythagorean theorem
2) h2 = a2 - x2
Rearrange the previous statement
3) c2 = h2 + (b-x)2
