Answer:
C = 25 + 50h
Step-by-step explanation:
cost for zero hours is $25, so that is the y-intercept of the graph.
each hours adds a cost of $50, so that is the gradient of the graph. These two values give us our equation in slope-intercept form.

Answer:
x=20 degrees
Step-by-step explanation:
Line y is a perpendicular bisector making a 90 degree angle with the base of the triangle. The Interior Angle Sum Theorem states that the sum of the interior angles of a triangle is always equal to 180 degrees. Add 70 to 90
70+90=160 degrees
Subtract the sum from 180
180-160=20 degrees
One x is equal to 20 degrees. Both x's are equal to 40 degrees.

The average median income for a dentist is $142,740. The average median income for a medical and health service manager is $86,400.
a. What is the average total income for a dentist over 30 years?
b. What is the average total income for a medical and health service manager over 30
years?
c. What is the difference between the earnings over 30 years?
A: For the Dentist, their average income in 30 years is $4,282,200
B: For the Manager, their average income in 30 years is $2,592,000
C: The difference in both their earnings is $1,690,200
Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.
I hope this helps you. :)

-3x-5<10 Equations
Answer:
x>-5
Step-by-step explanation:
First, we need to isolate the variable. To start doing this we can add five to both sides. We now have -3x<15. We then have to divde by -3. When working with inequalites you flip the inequality sign when dividing by a negative number. That then leaves us without answer, x>-5.

The number of machine parts produced at a manufacturing plant is based on the number of parts made in a given day
and the number of hours worked. Let P = 14x + 100 give the number of parts that are produced since the start of the
shift and H = x be the number of hours that are to be worked that particular day. Create the equation that would give
the number of parts produced per hour.
Answer:
The equation that would give the number of parts produced per hour, [tex]P_H[/tex] is given as follows;
[tex]P_H[/tex] = P/H - 100/H
Step-by-step explanation:
The given parameters are;
The number of parts produced is given by the equation, P = 14·x + 100, where x represents the number of hours worked on a particular day
The number of hours worked = H
Therefore, we have;
P = 14·H + 100
At H = 0, P₀ = 100
At H = 1, P = 114
At H = 2, P = 128
Therefore, the rate of change of the number of parts produced with the number of hours spent = The number of parts produced per hour, ΔP/ΔH = [tex]P_H[/tex], is given as follows;
ΔP/ΔH = [tex]P_H[/tex] = (P - P₀)/(H - 0) = P/H - P₀/H = (128 - 100)/(2 - 0) = 14
∴ The number of parts produced per hour, [tex]P_H[/tex] = P/H - 100/H.
find the value of x.
Given m∥n, find the value of x.
Answer:
x = 20
Step-by-step explanation:
The 2 given angles are alternate interior angles and are congruent, thus
7x - 3 = 6x + 17 ( subtract 6x from both sides )
x - 3 = 17 ( add 3 to both sides )
x = 20
• When volleyballs are purchased, they are not fully inflated. A partially inflated
volleyball can be modeled by a sphere whose volume is approximately 180 in). After
being fully inflated, its volume is approximately 294 in. To the nearest tenth of an
inch, how much does the radius increase when the volleyball is fully inflated?
Answer:
The radius increase when the volleyball is fully inflated is 0.5
Step-by-step explanation:
Volume of Partially inflated volleyball = 180 in³
Volume of Full inflated volleyball = 294 in³
We need to find how much does the radius increase when the volleyball is fully inflated?
First we will find the radius of both Partially inflated and Full inflated volleyball. Then we will find increase in radius.
The formula for Volume of sphere is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]
Finding Radius of Partially inflated volleyball
Volume = 180
Putting values and finding radius of Partially inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\180=\frac{4}{3}*3.14*r^3\\4.186r^3=180\\r^3=\frac{180}{4.186}\\r^3=43.0\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{47}\\r= 3.6[/tex]
So, radius of Partially inflated volleyball is r = 3.6
Finding Radius of Fully inflated volleyball
Volume = 294
Putting values and finding radius of Fully inflated volleyball
[tex]Volume=\frac{4}{3}\pi r^3\\294=\frac{4}{3}*3.14*r^3\\4.186\:r^3=294\\r^3=\frac{294}{4.186}\\r^3=70.23\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{70.23}\\r= 4.1[/tex]
So, radius of Partially inflated volleyball is r = 4.1
Now, finding increase in radius by subtracting radius of fully inflated volleyball with partially inflated volleyball
Increase in radius of Fully inflated volleyball = 4.1 - 3.6
Increase in radius of Fully inflated volleyball = 0.5
So, the radius increase when the volleyball is fully inflated is 0.5

Jada walks at a speed of 3 miles per hour. Elena walks at a speed of 2.8 miles per hour. If they both begin walking along a walking trail at the same time, how much farther will Jada walk after 3 hours? Explain your reasoning.
Answer:
Jada will be .6 miles ahead of Elena
Step-by-step explanation:
3 miles per hour times 3 (for the 3 hours) gives you nine miles.
2.8 miles per hour time 3 ( for the 3 hours) give you 8.4 miles.
Subtract 9 by 8.4 to get .6 miles.
A repairman charges an inspection fee plus $16 per hour. A customer with a coupon for 30% off the inspection fee pays $74 for a 2-hour repair. How many hours are worked when a customers pays $124 without a coupon?
Answer:
I want to say that the hours worked was 4. I hope that is right.
Step-by-step explanation:
30% off of $60 is 42
16*2=32 and 32+42=74
124-60=64
16*4=64
so he would have worked 4 hours for $64 and a fee of $60
64+60= 124
Camden is making accessories for the soccer team. He uses 632.25 inches of fabric on headbands for 41 players and 4 coaches. He also uses 361.21 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Camden used 22.86 in of fabric for each player.
What is division?Division is breaking a number up into an equal number of parts.
Given that, Camden uses 632.25 inches of fabric on headbands for 41 players and 4 coaches. He also uses 361.21 inches of fabric on wristbands for just the players.
4 coaches + 41 players = 45 persons
Fabric used for headband for one person = 632.25 / 45 = 14.05 in
Fabric for 41 players = 14.05 × 41 = 576.05 in
Fabric for wristband = 361.25
Total fabric used on players = 361.25+576.05 in = 937.26 in
For each of them = 937.26 in / 41 = 22.86 in
Hence, Camden used 22.86 in of fabric for each player.

Kelly purchased 5 containers of ice cream for a party. Each container holds 8 cups of ice cream. Before the party, her brother ate 2 cups of ice cream. If one serving of ice cream is 23 of a cup, how many servings of ice cream will be left for the party?
Given:
Kelly purchased 5 containers of ice cream for a party.
Each container holds 8 cups of ice cream.
Her brother ate 2 cups of ice cream.
One serving of ice cream = 2/3 of a cup.
To find:
Number of servings of ice cream will be left for the party?
Solution:
We have,
1 container = 8 cups of ice cream
5 containers = 5×8 = 40 cups of ice cream
Her brother ate 2 cups of ice cream. So, remaining cups of ice cream is
[tex]40-2=38[/tex] cups
Now,
[tex]\dfrac{2}{3}[/tex] of a cup = 1 serving
1 cup = [tex]\dfrac{3}{2}[/tex] serving
38 cup = [tex]38\times \dfrac{3}{2}[/tex] serving
= [tex]19\times 3[/tex] serving
= 57 serving
Therefore, 57 servings of ice cream will be left for the party.
