Devon earns $35 per hour for a regular 40-hour work week. Sometimes, he works over 40 hours a week and earns "double time" for the extra hours worked. (That means that his hourly rate for the additional hours over 40 hours per week is double his normal hourly rate.) If Devon works 48 hours in one week, how much would he earn that week?
Answer:
1960
Step-by-step explanation:
40 times 35 = 1400
8 times 2 times 35 = 560
1400+560=1,960$
When Devon works for 48 hours in one week the total amount he earned that week is equal to $1960.
To calculate Devon's earnings for the week when he works 48 hours,
Consider his regular pay for the first 40 hours and then the "double time" pay for the additional 8 hours.
Regular pay for 40 hours: Devon earns $35 per hour for a regular 40-hour work week.
Regular pay = $35/hour × 40 hours = $1400
Overtime pay for the additional 8 hours: Devon works 48 hours in total, so he works 8 hours over the regular 40-hour work week.
For these 8 hours, he earns "double time," which means his hourly rate is doubled.
Double time rate = 2 × $35 = $70/hour
Overtime pay
= Double time rate × Number of overtime hours
= $70/hour × 8 hours
= $560
Total earnings for the week: To find the total amount earned in the week, add the regular pay and the overtime pay.
Total earnings
= Regular pay + Overtime pay
= $1400 + $560
= $1960
Therefore, if Devon works 48 hours in one week, he would earn $1960 that week.

What is y + 3 = 7(x − 2) written in standard form?
Answer:
7 x − y = 17
Step-by-step explanation:
Apply the distributive property.
y + 3 = 7 x+ 7 ⋅ − 2
Multiply 7 by − 2 .
y + 3 = 7x − 14
Rewrite the equation with the sides flipped.
7 x − 14 = y + 3
Move all terms containing variables to the left side of the equation.
Subtract y from both sides of the equation.
7x−14−y=3
Move -14.
7x−y−14=3
Which statement most reasonably explains the hours when zero calls were received? Medera turned the phone off while playing in a soccer game. Medera's phone can only receive 22 calls a day. Medera only receives calls in clusters. Medera lost her phone for two hours.
Answer:
Medera turned the phone off while playing in a soccer game.
Step-by-step explanation:
From the possible scenarios provided the one that would indicate this would be when Medera turned the phone off while playing in a soccer game. This is because since her phone was off it was not getting any phone signal which means that no incoming calls would have been received during that time. When Medara lost her phone for two hours, even though she did not have it on her the phone was still on and connected to a network which means that the calls were coming in.

which statements are true about the polynomial function?
f(x)=x^3+5x^2+6x
Statements given in the Options (3) and (4) are the correct.
Polynomial function given in the question is,
f(x) = x³ + 5x² + 6x
Check all the options whether they are true or false.
Option (1)
f(x) = 0 at x = 2,
Substitute the value x = 2 in the polynomial.
f(2) = (2)³ + 5(2)² + 6(2)
= 8 + 20 + 12
= 40
False.
Option (2)
(x + 2) is a factor of f(x).
If it's true, f(x) = 0 will be true for x = -2
Substitute x = -2 in the function,
f(-2) = (-2)³ + 5(-2)² + 6(-2)
= -8 + 20 - 12
= -20 + 20
= 0
True.
Option (3)
f(-2) = 0
f(-2) = (-2)³ + 5(-2)² + 6(-2)
= -8 + 20 - 12
= 0
True.
Option (4)
f(x) divided by (x - 2) has a remainder of 0.
x - 2)x³ + 5x² + 6x(x² + 7x
x³ - 2x²
7x² + 6x
7x² - 14x
20x
Here, remainder is (20x).
False.
Therefore, Options (3) and (4) are correct.

Solve 24x + 2y = 48 for y.
Answer:
y = 24 - 12x
Step-by-step explanation:
24x + 2y = 48
Get 2y by itself and subtract 24 x on both sides.
24x + 2y = 48
-24x -24x
2y = 48 - 24x
To have y all by itself, divide by 2 on both sides.
2y = 48 - 24x
/2 /2
(You have to divide 2 by everything on the other side so...)
y = 24 - 12x

Select the correct answer. A baseball is hit from an initial height of 3 feet and reaches a maximum height of 403 feet. Which function could be used to model this situation, where is the height, in feet, after t seconds?
Answer:
ΔS = 1/2gt²
Step-by-step explanation:
Given
Initial height of the ball = 3 feet
Maximum height of the ball = 403 feet
To get the function that best suits the situation after t seconds, we will use the equation of motion;
ΔS = ut + 1/2gt²
ΔS is the change in height
u is the initial velocity of the body = 0m/s
g is the acceleration due to gravity = 9.81m/s²
t is the time taken for the ball to reach its maximum height.
ΔS = 403-3
ΔS = 400ft
Substituting the given values into the formula;
ΔS = ut + 1/2gt²
400 = 0 + 1/2(9.81)t²
400 = 4.905t²
t² = 400/4.905
t² = 81.55
t = √81.55
t = 9.03secs
The situation that best model the situation is ΔS = ut + 1/2gt²
ΔS = 0 + 1/2gt²
ΔS = 1/2gt²
