1. A plumber charges $50 for a house call in addition to $80
per hour worked. Which equation represents y, the total cost
for x, hours worked?
Answer:
Step-by-step explanation:
Since the plumber charges $50 regardless of how many hours he works, then the equation must be 50 + ....
Since the plumber charges $80 for each hour, then the equation will be y = 50 + 80x.

1. Sarah and Maya both need notebooks and pencils. The equation that represents Sarah's
purchases is y = 13- 3x. The equation that represents Maya's purchases is y = 7 -x. If y
represents the price of notebooks, and x represents the price of pencils, what are the prices of
the notebooks and pencils?
a) pencils: $4 notebook: $3 go to card 4
b) pencils: $6 notebook: $1 go to card 3
c) pencils: $3 notebook: $4 go to card 5
d) pencils: $1 notebook: $6 go to card 7
e) pencils: $4 notebook: $4 go to card 2
Step-by-step explanation:
We have y = 13 - 3x and y = 7 - x.
=> 13 - 3x = 7 - x
=> 2x = 6, x = 3.
Then y = 7 - (3), y = 4.
Hence the price of a pencil is $3 and the price of a notebook is $4. (C)
answer is c) pencils: $3 notebook: $4 go to card 5

What is the area of the sector of the circle when the radius is 10 and the shaded part is 45 degrees
Answer:
We are solving for the area so; A=134.16
Step-by-step explanation:
Here is the formula for finding area of a sector:
A = [tex]\pi r^{2}[/tex] × θ° ÷ 360°
where theta is the angle of the sector you wish to find, and r is the radius of the circle.
Substitute the numbers in and you get:
[tex]\frac{25\pi }{2} unit ^{2}[/tex]
You should find 39.26991 as your answer (or any number rounded according to the value of pi)

Explain why a systems engineer would work for the Federal Aviation Administration and describe his or her role.
Answer 1 (edge correct answer):
One correct answer is that a systems engineer might work in air traffic control designing an air traffic control solution program. The program may be used to train thousands of air traffic controllers to ensure they can perform their jobs effectively.
Answer 2 (answer I made myself)
Explain why a systems engineer would work for the Federal Aviation Administration and describe his or her role.
A systems engineer would work for the Federal Aviation Administration because systems engineers are able to develop systems that manage the many technological systems that are on modern ships, planes, helicopters, etc. A systems engineer's role would be to design requirements, gather data, and develop systems for the project they are working on. Systems engineers are almost always required in projects made by the Federal Aviation Administration. The reason I believe that systems engineers are required in the FAA is because: "In an information technology field, an engineer may work to develop systems in virtually any industry. Health care, education, financial services, and transportation industries need information technology developers, managers, and engineers. In the transportation field, a systems engineer might work in air traffic control for a company that works for the Federal Aviation Administration. A systems engineer would help develop an air traffic control solution program. The program may be used to train thousands of air traffic controllers to be sure they can perform their jobs effectively." This evidence shows how the role as systems engineer has relates to joining with the FAA (Federal Aviation Administration).

A group of college students spent $58.50 for dinner and wanted to leave a 15% tip. Which is the closest to the amount they should leave?
$4
$6
$9
$12
Answer:
9 dollars
Step-by-step explanation:
58.5 times .15 = 8.775 which can be rounded up to 9 dollars
If group of college students spent $58.50 for dinner and wanted to leave a 15% tip. Then $9 is the tip.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
A group of college students spent $58.50 for dinner
The students want to leave a tip of 15%.
We need to find how much they has to leave as tip.
Firstly we have to convert 15% to decimal.
We have to divide 15 by 100
15/100
0.15
Now we have to multiply 0.15 with 58.50 to find the 15% of 58.50
0.15×58.50
8.775
9
Hence, $9 is the tip the students has to leave.

Mikayla subracted 4 from both sides, not add. She was supposed to add so that the -4 can cancel out.

Answer:
We conclude that:
h(f(-1)) = -2
∴ option D i.e. -2 is correct.
Step-by-step explanation:
Given
f(x) = 4x² - 1
g(x) = 1/2x + 5
h(x) = 2(x - 4)³
To determine
h(f(-1)) = ?
In order to determine h(f(-1)) first we need to determine f(-1).
substitute x = -1 in the function f(x) = 4x² - 1
f(-1) = 4(-1)² - 1
f(-1) = 4(1) - 1
f(-1) = 4-1
f(-1) = 3
so
h(f(-1)) = h(3)
now substitute h = 3 in the function h(x) = 2(x - 4)³
h(x) = 2(x - 4)³
h(3) = 2(3 - 4)³
h(3) = 2(-1)³
h(3) = 2(-1)
h(3) = -2
Thus,
h(f(-1)) = h(3) = -2
Hence, we conclude that:
h(f(-1)) = -2
∴ option D i.e. -2 is correct.
