companies. After how many miles
are the total costs at the
OI two truck rental
two companies equal?
Company A:
Company B:
$20 per day plus $.70 per mile
$45 per day plus S .25 per mile
Answers
Set up the equation and solve for miles:
20 + 0.70m = 45 + 0.25m
Subtract 20 from both sides
0.70m = 25 + 0.25m
Subtract 0.25m from both sides
0.45m = 25
Divide both sides by 0.45
M = 55.56 miles
answer: 55.56 miles ( rounded to nearest hundredth’s)

What is the area of the shaded region below?
Answers
Answer:
Step-by-step explanation:
Remark
The triangle with the shaded region makes exactly 1/4 of the entire circle. So the plan is to find the area of the circle and divide by 4. That gives you the area of the triangle and the shaded region. Then you find the area of the triangle and subtract it from what you just found.
Area of the circle
Area of the circle = pi * r^2
r = 12 cm
pi = 3.14
Area of the circle = 3.14 * 12^2
Area of the circle = 3.14 * 144
Area of the circle = 452.16 cm^2
Area of 1/4 of the circle
Area of 1/4 of the circle = (1/4)*452.16
Area of 1/4 of the circle = 113.04
Area of the triangle
b = r
h = r
b = 12 cm
h = 12 cm
Area = 1/2 b * h
area = 1/2 * 12 * 12
area = 72
Area of the shaded part
Shaded part = area of 1/4 of the circle - area of triangle
Area shaded part = 113.04 - 72 = 41.04
Answer area of shaded part = 41.04

Write f(x)=|x-2| as a piecewise function.
Answers
Answer:
Hi! A piecewise function is a function defined by multiple sub-functions, or pieces of different functions over different intervals. Piecewise definition is a way of expressing the function and is not actually integral to the function itself.
f(x) = |x - 2| is an absolute value function. As a piecewise function, it's written like this:
f(x) = {x - 2, x ≥ 2
{-x + 2, x < 2

Answers
The number of sixty-minute cassette tapes ordered is 288 and the number of CDs ordered is 163.
What are the linear equations that represent this question?1.49a + 4.98b = $1240.86 equation 1
a + b = 451 equation 2
Where:
a = number of sixty-minute cassette tapes ordered b = number of CDs orderedHow many CDs were ordered?Multiply equation 2 by 1,49
1.49a + 1.49b = 671.99 equation 3
Subtract equation 3 from equation 1
568.87 = 3.49b
Divide both sides of the equation by 3.49
568.87 / 3.49

Jason is considering two different jobs that he has been offered and he likes the atmosphere and
other employees equally at both companies.
With the first job he would be an apartment property manager for AMLI Company. This job is
offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he
sets a one year lease up with. The company expects Jason to work all 52 weeks of the year and 40
hours per week. He was told he could expect to set up an average of 5 lease agreements for each
week that he works.
With the second job he would work as water treatment facility manager in Gwinnett County. He
would be paid an annual salary of $46,000 a year, there are no bonuses by he gets a week off.
Both companies deduct for Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and
Federal Income Tax (14%).
AMLI's individual health insurance costs $115 per month. Gwinnett County's health insurance is
only $25 per month for an individual.
Part A: Determine how much Jason will receive in one year after all deductions have been taken
for each company. Show your work neatly.
Answers
The amount of money that Jason will receive in one year after all deductions have been taken for each company is $30,780.5 and $32562.
What is the final amount?With the first job, he would be an apartment property manager for AMLI Company.
This job is offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he sets a one-year lease-up with.
The company expects Jason to work all 52 weeks of the year and 40 hours per week.
He was told he could expect to set up an average of 5 lease agreements for each week that he works.
The amount after one year will be given by an equation
Let y be the amount, x be the number of hours in a week and z be the number of the week.
y = 19x + 40z
The total number of hours in a year will be
x = 2080
Then
y = 19 × 2080 + 40 × 52
y = $ 41,600
The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be
→ 41,600 × 0.938 × 0.988 × 0.97 × 0.86
→ $ 32,160.5
The amount after the insurance will be
Amount = 32160.5 - 115 × 12
Amount = $ 30780.5
With the second job, he would work as a water treatment facility manager in Gwinnett County. He would be paid an annual salary of $46,000 a year, there are no bonuses and he gets a week off.
The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be
→ 46,000 × 0.938 × 0.988 × 0.97 × 0.86
→ $ 35,562
The amount after the insurance will be
Let the number of the worker be 10. Then
Amount = 35,562 - 10 × 12 × 25
Amount = 35562 - 3000
Amount = $32562
