Answer:
Part 2) 5 hr
Part 3) $80 and $160
Step-by-step explanation:
Part 2) Equate the two pay equations: 20H = 10H + 50
Subtract 10H from both sides: 10H = 50
Then H = 5.
After 5 hours, each would have earned the same amount.
Part 3) In an 8-hour day, one guy would earn ($20/hr)(8 hr) = $160, and the other guy would earn ($10/hr)(8 hr) = $80.
Answer:
2. 5 hours
3. $80 and $160

The cost of tuition at the college that Lacy wants to attend is $12,500 per year. Lacy’s family will pay 70% of the tuition cost each year. Lacy has two years to save enough money to attend her first year of college. What is the minimum amount that she should save each month in order to have enough money to attend her first year of college?
$156.25
$729.17
$3,750.00
$312.50
Answer:
$312.50
Step-by-step explanation:
1: 12,500 x .70 = 8,750
2: 12,500 - 8,750 =3,750
3: 3,750 ÷ 12 = 312.5
Bye Bye :)
The minimum amount that she should save each month in order to have enough money is $312.5
What is percentage?A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.
Given that, The cost of tuition at the college that Lacy wants to attend is $12,500 per year. Lacy’s family will pay 70% of the tuition cost each year. Lacy has two years to save enough money to attend her first year of college.
The amount Lacy have to pay = (70-30)% of 12500 = 30% of 12500
= 125×30 = $3750
Each month = 3750/12 =32.50
Hence, the minimum amount that she should save each month in order to have enough money is $312.5

USE THE SQUARE ROOT PROPERTY!!!!!
the sides of a square are reduced by 2 inches. the new area is 20 square inches. Set up and solve an equation to find the original length of the square
Answer:
Step-by-step explanation:
x = original length of one side
(x-2)² = 20 inches²
x-2 = ±√20 = ±2√5
x = 2±2√5
2-2√5 is an extraneous solution,
so x = 2±2√5 ≈ 6.47 inches
Ella and Jake love to skateboard. They created a frame for the ramp and then covered it with wood.
How much wood did it take to cover the ramp, including the bottom?
Give an exact answer (do not round).
Answer:
triangle side = 0.54
so both triangle sides = 1.08
and then the sides (1.5 * 3.5) * 2 = 10.5
the last side = 0.9 * 3.5 = 3.15
so add it all 3.15 + 10.5 + 1.08
total area = 14.73 m^2

Here is Laila’s graph from the previous screen.
Write your own equation in the form y=mx+b that could represent Laila’s graph.
Answer:
y=-1/3x+8
Step-by-step explanation:
There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

How many cubes with side lengths of 1/2 does it take to fill the prism?
Answer: 24 cubes
Step-by-step explanation:
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500
