Answer:
Percentage Change | Increase and Decrease
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
Step-by-step explanation:
hopefully this helped and you can find the percent change.

The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle

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.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Salesman A Salesman B Salesman C
s = 0 (0,

s = 1 (1,

s 10 (10,

) (10,

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

There are two unknowns you are trying to find, and you cannot express one in terms of the other. Describe how you could use algebra to solve for the unknowns.
Answer:
When you solve systems with two variables and therefore two equations, the ... of any variable is 1, which means you can easily solve for it in terms of the other ... In the substitution method, you use one equation to solve for one variable and ... Look for a variable with a coefficient of 1 … that's how you'll know where to begin.

What are the answers to these questions??
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
C. The ratio of red to blue cubes is 10:4. True
D. The ratio of all cubes to blue is 28:20. False

Step-by-step explanation:
If the equation is 0=0.64z-z+0.36z and the answer is true for all z what are 2 values to check the solution
Example of what I mean...
Answer:
You can choose trivial values such as [tex]z=0[/tex], but also something like [tex]z=69[/tex] if you feel more daring. Both equations will come out to yield [tex]0=0[/tex], which is obviously true.
Step-by-step explanation:
Because the answer is true for all [tex]z[/tex], any two values can be chosen. It is most often useful to choose easy values of [tex]z[/tex] for these kinds of situations, though.

Step-by-step explanation:
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.
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).

2. What is the sales price for an Xbox 360 that originally sells $230 if it is on sale for 28% off the original price?
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?
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
