Answer:
lifeguarding: 6 hours
tutoring: 10 hours
Step-by-step explanation:
First, to be able to tell apart the two jobs, use the variable x and y for them. use x for lifeguarding and y for tutoring. Since you have the pay per hour, you can create an expression for his pay:
11x + 22y
Then, write a system of equations to be able to find both variables.
If Parker worked a total of 16 hours, then you know that the combined amount of worked hours will be:
x + y = 16
If Parker earned a total of $242, then you know that his combined pay will be:
11x + 22y = $242
Now, you solve the system of equations (IMAGE.A):
First, solve for x:
11x + 22y = 242
11x = 242 – 22y
x = 22 – 2y
Now, plug in the x-value in the other equation:
x + y = 16
22 – 2y + y = 16
22 – y = 16
–y = –6
y = 6
This means that he has worked 6 tutoring hours.
Now, plug in the y-value to find the x-value:
11x + 22y = 242
11x + 22(6) = 242
11x + 132 = 242
11x = 110
x = 10
this means that he has worked 10 lifeguarding hours.
Answer:
10 hours lifeguarding, 6 hours tutoring

Step-by-step explanation:
what is 0.0042 as a fraction in simplest form
Answer:
21/5000
Step-by-step explanation:
0.0042 takes the form of 21/5000 as a fraction.
Answer:
21/500
Step-by-step explanation:
0.0042 = 42/1000, (There is 4 digits to the right of the decimal point)
42 is an even number so, divide by 2 to simplify.
42/2 = 21 and 1000/2 = 500
21/500 is your final answer because 21 is divisible by 7 and 3 but 500 cannot be divided by either of those to get a whole number.
Hope this helps! :)

Answer:
f (x+4) = -5x -18A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
The slope is 0.75 as 3/4 = 0.75
Answer:
Step-by-step explanation:
Only the blue line has a positive slope. So the new line is parallel to the blue line.
Clearly, the blue line goes through the point (0, 3) (this is the y-intercept). Follow this blue line upward and to the right until it intersects the horizontal line at the top of the diagram. We must estimate the x-value of this point of intersection. A good approximation would be 5 1/3.
Now estimate the slope of the blue line. Starting at (0, 3), we move 5 1/3 units to the right (this is the "change in x," or "run") We end up at (5 1/3, 3).
Now, from the horizontal line y = 3 upward to the horizontal line at the very top of the graph, is 5 units. This is the "rise."
Thus, the approximate value of the slope here is
5 5 15
m = rise / run = ---------- = -------------- = ----------- = m

Sanjay consulted three electricians about upgrading the wiring in his home. Each electrician uses a linear formula that incorporates a flat base fee and an hourly rate to determine the cost of service. Those formulas are shown in the table.
Repair Cost Formulas
Electrician
Cost in y dollars for an x-hour service
1
y = 25 x + 30
2
y = 30 x + 25
3
y = 25 x + 20
Which statement is best supported by the table?
Each electrician charges a different hourly rate.
Each electrician charges a different base fee.
All three electricians charge the same hourly rate.
All three electricians charge the same base fee.
Answer: B: each electrician charges a different base fee
Step-by-step explanation:
Answer:
b.Each electrician charges a different base fee:
Explanation:
Each of the equations has two parts:
1- base fee that is independent of any variable (this would be the number that has no variable next to it)
2- an hourly rate depending on the number of hours x (this would be the number that has an x next to it)
For the first electrician:
y = 25x + 30
base fee = $30
hourly rate = $25
For the second electrician:
y = 30x + 25
base fee = $25
hourly rate = $30
For the third electrician:
y = 25x + 20
base fee = $20
hourly rate = $25
Now, let's check the choices:
a.Each electrician charges a different hourly rate:
This is incorrect as electricians 1 and 3 charge the same hourly rate ($25)
b.Each electrician charges a different base fee:
This is correct as all three base fees are different ($30, $20 and $25)
c.All three electricians charge the same hourly rate:
This is incorrect as electrician 2 has a different hourly rate
d. All three electricians charge the same base fee:
This is incorrect as the base fees for the three electricians are different ($30, $25 and $20)

The diagram below represents which percent?
An area model with 4 shaded sections and 1 unshaded section.
4%
45%
75%
80%
Answer:
80%
Step-by-step explanation:
There are 4 shaded sections and 1 unshaded section, so five sections in total.
4 sections are shaded, so the fraction would be 4/5.
Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
Answer:
D. 80%
Step-by-step explanation:
Well, the diagram shows 4/5ths knowing this is more than half we can auto matily mark out the first two A. and B. leaving C. 75% and D. 80% and D. is the best choice (sorry go too lazy to explain...)
