Fred works for $11.25 per hour. His regular hours are 40 hours per week and he gets time and a half for overtime. One week he works 48.5 hours. He wants to calculate his pay. Complete the table. Rate Regular Hours Overtime Hours Total N/A $ $11.25 $ N/A $ Gross $ Unlimited Attempts Remain
Step-by-step explanation:
The first row
Rate per hour is $11.25Number of regular hours is 40Payment for regular hours:
40*$11.25 = $450The second row
Rate per overtime hour:
$11.25*1.5 = $16.875 ≈ $16.88 (rounded up)Number of overtime hours:
48.5 - 40 = 8.5Payment for overtime hours:
$16.88*8.5 = $143.48The third row
Gross payment is the sum of regular and overtime payments:
$450 + $143.48 = $593.48What is the value of 5^2+0.7^2Enter the answer in the box.

Jennifer's bank account is modeled by the following equation where equals the number of months and y equals the balance: y = 24x + 50
Answer:
50
Step-by-step explanation:
Jennifer's bank account started with 50 because that's the y-intercept in the equation (y= mx+b). b is always what you start with.
Answer:
Part A: 50 dollars
Part B: y=28x+60
Part C: Jennifer is wrong
Part D: William will a greater balance
Step-by-step explanation:
A: Jennifer's equation is represented in slope-intercept form, or y=mx+b, where m is how much she earns per month, and b is her initial value, therefore, her initial value is 50.
B: Using the table, we can use y=mx+b as a formula. We first find the slope by doing 88-60=28. Then we see that at month 0, his initial value is 60, leaving us with y=28x+60.
C: Using the slopes for both equations, we see the William's balance is growing by 28, 3 more than Jennifer's 25.
D: We can plug in 12 for x for both equations. 25(12) + 50 = 338 28(12) + 60 = 396
Which function has a greater y-intercept?
A. F
B. P
C. The functions have the same y-intercept.
Answer:
The table / first one
Step-by-step explanation:
The y-intercept is when x, or t, is 0. For the graph the y-intercept is -2 and the table has a y-intercept of -1.5
-1.5 > -2
Hence our answer.

Answer:
B (0,2)
Step-by-step explanation:
y-intercept means where the line crosses the y-axis. The y-axis is the vertical line. Coordinate points are recorded as (x,y). The y-intercept is (0,2). Aka, when x = 0, y = 2.
Mary used the equation 292 = 5h + 192 to determine her
salary at the restaurant last week. Which situation does this
equation best represent?
Answer:
Mary worked 10 hours last week and received $192 in tips for a total income of $292.
Step-by-step explanation:
I don't see any answer options. The best I can assume is that h stands for hours. If so, Mary makes $5/hour. The 1932 doesn't have units, but I'll assume it is $. The $192, I'll guess, is her average weekly tip income. The difference between 292 and 192 is $100, so that would mean Mary worked 20 hours last week. Her tip income is almost double her salary.

if it 7:40 and you add 50 minutes what time would it be now
Answer:
8:30
Step-by-step explanation:
From 7:40 we need 20 min to get to 8:00
From 8:00 we add 30 min and get 8:30.
(20 min + 30 min = 50 min)
Answer: 8:30am/pm time
Step-by-step explanation:
7:40am/pm time + 50 minutes
7:40am/pm time after 10 minutes = 7:50am/pm time | 7:40am/pm time + 10 minutes = 7:50am/pm time
7:40am/pm time after 20 minutes = 8:00am/pm time | 7:40am/pm time + 20 minutes = 8:00am/pm time
EX: Because after :59 minutes/seconds you increase the hour or minute by 1 which then would be 1:00 hour/minute
7:40am/pm time after 30 minutes = 8:10am/pm time | 7:40am/pm time + 30 minutes = 8:10am/pm time
7:40am/pm time after 40 minutes = 8:20am/pm time | 7:40am/pm time + 40 minutes = 8:20am/pm time
7:40am/pm time after 50 minutes = 8:30am/pm time | 7:40am/pm time + 50 minutes = 8:30am/pm time
An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece. What is the length of the shorter piece of wire? Enter your answer as a number only (no letters or symbols). Do not include units.
The length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.
Given to us
An electrician needs to cut a 49 m piece of wire into two pieces so that one piece is 5 m longer than the other piece.
What are the two equal parts of the wire?We know that the length of the wire is 49 m, therefore, to cut the wire in two equal parts divide the total length of the wire by two,
[tex]\dfrac{49}{2} = 24.5[/tex]
Thus, the length of each side will be 24.5.
What is the length of the shorter piece of wire?Since we need to cut the wire such that one side of the wire is 5 less than the other, we already know the length of the equal sides deduct (5/2) from both sides to create a difference between the length of the wire.
Length of the shorter wire = 24.5 -2.5 = 22.5
Length of the longer wire = 22.5 + 5 = 27.5
Hence, the length of the shorter wire that the electrician cuts so that the difference between those two is of 5 m is 22.5.

a=6, b=2
Step-by-step explanation:
Use simplification into substitution
[tex]\frac{a}{3} =1+\frac{2}{b}[/tex]
[tex]a=3(1+\frac{2}{b})[/tex]
[tex]a=3+\frac{6}{b}[/tex]
We can now plug this value of a into the second equation.
[tex]\frac{3+\frac{6}{b} }{4} +\frac{3}{b} =3[/tex]
Get rid of fractions in the numerators and/or denominators
[tex]\frac{3b+6}{4b} +\frac{3}{b} =3[/tex]
Then we can match the denominators
[tex]\frac{3b+6}{4b} +\frac{12}{4b} =3[/tex]
Combine
[tex]\frac{3b+18}{4b} =3[/tex]
Divide both sides by three
[tex]\frac{b+6}{4b} =1[/tex]
Get rid of fractions
[tex]b+6=4b[/tex]
Single out b

Which set of lengths CANNOT form a triangle? A. 16, 18, 20 B. 13, 14, 23 C. 8, 6, 5 D. 14, 20, 3
just a quick addition to the great reply above, Check the picture below.
notice on the picture atop, if we lay the 14 side on top of the 20 side, the slack is just 6, however we get a flat-line not a triangle, so the red side must be greater than 6 for that.
on the picture below, if we had the two small sides to open to a flat line, they add up to 17, no way to fit a side of 20 there, so the red side must be less than 17.
the average of a list of 6 numbers is 20. if we remove one of the numbers the average of the remaining numbers is 15. what is the number that was removed
Answer:
Solution,
Average of 6 numbers=20
Total of 6 numbers=6 x 20=120
When one number is removed,
the average of 5 numbers=15
the total of 5 numbers=15x5=75
Now,
the number that was removed=120-75=45
Hence, 45 was the number.
