Find the rate of change from 2012 to 2016
A. -10.5 students per year
B. 10.5 students per year
C. -11.25 students per year
D. 11.25 students per year
Answers
Answer:
D. 11.25 students per year
Step-by-step explanation:
rate of change
[tex] = \frac{400 - 355}{2016 - 2012} [/tex]
[tex] = \frac{45}{4} [/tex]
=11.25
The rate of change from 2012 to 2016 is 11.25 students per year.
Therefore, the correct answer is D.
Given that a graph is showing the number of students in a class.
We need to find the rate of change from 2012 to 2016.
Also, from the graph we can see the number of students in 2012 and 2016 was 355 and 400 respectively.
To find the rate of change from 2012 to 2016, we can use the formula:
Rate of change = (Final value - Initial value) / Time interval
In this case, the initial value is the number of students in 2012, which is 355, and the final value is the number of students in 2016, which is 400.
The time interval is 4 years (from 2012 to 2016).
Plugging these values into the formula, we get:
Rate of change = (400 - 355) / 4
= 45 / 4
= 11.25
Therefore, 11.25 students have changed between 2012 and 2016 with this rate of change.

Answer:
The answer is C. But I got 350.82
Step-by-step explanation:
The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48
The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82
Then we add up all the areas 302.82+48 to get 350.82
Because this answer is slightly different I would assume it is C.

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.
a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.
Answers
Answer:
Equation: y=(-1/20)x+12.
Slope: -1/20
Y-intercept: (0, 12)
Step-by-step explanation:
Let x=the number of gallons of gas in Christopher's car.
If we start with 12 gallons, we have the equation: y=(-1/20)x+12.
This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

No.
Step-by-step explanation:
72 times 0.15=10.8
72-10.8=61.2
No. Taylor doesn't have enough.
You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.

3. What is the difference between discounting a $45,000 car by 25% versus marking up the price of the car by 25%?
4. How much would you pay for the discounted price of the car including 8.875% sales tax?
5. How much would you pay for the marked up price of the car including 8.875% sales tax?
6. If Thomas helped you buy the car that was on sale in question #3, he is entitled to a 6% commission at Sherman Auto Mall. How much commission will he earn for the car that was "on-sale" in #3?
Answers
see below
Step-by-step explanation:
2.) $230 x 28% = $64.40
$230 - $64.40 = $165.60 sales price
3.) $45,000 × 25% = $11,250
$45,000 - $11,250 = $33, 750 discount price
$45,000 + $11,250 = $56,250 mark up price
$56,250 - $33,750 = $22,500 answer
4.) $33,750 x 8.875% = $2995.31
$33,750 + $2995.31 = $36,745.31 with tax
5.) $56,250 x 8.875% = $4,992.19
$56,250 + $4,992.19 = $61,242.19 with tax
6.) $33,750 x 6% = $2,025.00 Tom's commision

Answer:
1) c and d
2) 44
3) a and c
1: if 96 is the 100% price and 32% is what you need to find, it is 32 out of 100. 0.32 is the same, as well as 32/100.
2: if you divide the shape into different pieces, i find it easier to find the area. 9 x 3 = 27. 4 x 2= 8. 3 x 3 = 9. 27+8+9=44.
3: the ratio 8:20 can be simplified down to 2:5 which makes A true. if the ratio is originally blue:red, then for c, 10:4 is the same as 4:10 since it states red to blue instead of blue to red, meaning c is also true.
Answer:
1. C and D.
2. 34
3. A and C
Step-by-step explanation:
1. All you have to do is solve each equation in order to see which ones are equal to the same answer
A. 32 * 96 = 3072
B. 3.2 * 96 = 307.2
C. 0.32 * 96 = 30.72
D. 32/100 * 96 = 30.72
Both C and D have the same answer.
2. Add up all the sides
9+6+5+4+3+3+2+2= 34
3. Look at each answer carefully.
A. There are 2 blue cubes for every 5 red cubes. True
B. When the game has 56 cubes in all, there are 40 red cubes. False

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.

Answers
Answer:
12 sales
Step-by-step explanation:
Let x represent the number of sales each man had.
For Salesman A, he earns $65 per sale; this is 65x.
For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.
Since their pay was equal, set the two expressions equal:
65x = 40x+300
Subtract 40x from each side:
65x-40x = 40x+300-40x
25x = 300
Divide both sides by 25:
25x/25 = 300/25
x = 12
