How do you find the markup rate?
Answer: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%.
Step-by-step explanation:
Answer:
hope this helps!
Step-by-step explanation:
Divide the amount added to the price by the amount the item costs you to buy to find the markup rate expressed as a decimal. In this example, you would divide $2 by $6 to get 0.3333. Convert the markup rate expressed as a decimal to a markup rate expressed as a percentage by multiplying it by 100.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (-9, -1) and (3, – 7).
Answer:
y-4=1(x-6) and y= x 10
Step-by-step explanation:
Which of these lengths is the greatest?
8 feet or 100 inches
Answer:
100 inches is greater..
Step-by-step explanation:
1 foot = 12 inches 8 feet = 96 inches (100 inches is longer than 8 feet ). 100 inches is greater than 8 feet which equals 96 inches.
They both round up to 8 feet, so they're equal.
If you're asking for an exact answer though, it'd be 100 inches since it's 4 inches above 8 feet.

3/4x = 2 1/4
A. 5
B. 3
C. 1
D. 2
Answer:
the answer is B
Step-by-step explanation:
here's why.... 2 times 4 plus 1 is 9 so ... 2 1/4 turns into 9/4 and 3 times 3 is 9 so if u place x with 3 it will be 9/4 therefore the fractions are equal.
Mr. Boyd completed a 3.19 mile walk/ run. For every 5 minutes of walking, he ran for 1.5 minutes. If he completed his workout in 48:52 minutes, how much of that time was spent running?
Answer:
He spent 11.25 minutes running
Step-by-step explanation:
Mr. Boyd completed a 3.19 mile walk/ run.
For every 5 minutes of walking, he ran for 1.5 minutes.
He completed his workout in 48.52 minutes.
Hence, we have the equation:
1.5x + 5x = 48.52 minutes
6.5x = 48.52 minutes
x = 48.52/6.5
x = 7.4646153846
Approximately = 7.5 minutes
Therefore the time spent running = 1.5 × 7.5 minutes
= 11.25 mimutes

1) m2 = 3x - 6
120 X
2.
A) 12
C) -11
B) 10
D) 6
Answer:
A
Step-by-step explanation:
Since the 2 legs are congruent then the triangle is isosceles and therefore the base angles are congruent, that is
∠ 2 = [tex]\frac{180-120}{2}[/tex] = [tex]\frac{60}{2}[/tex] = 30° , thus
3x - 6 = 30 ( add 6 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12 → A
The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters. What is the volume of the rectangular prism in cubic centimeters?
Answer:
V = 288 cm³
Step-by-step explanation:
Given that,
The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters.
We need to find the volume of the rectangular prism. For a rectangular prism, the volume is given by :
V = lbh
Since, lb = A, area of the prism
V = Ah
V = 24 × 12
= 288 cm³
So, the volume of the rectangular prism is 288 cm³.

3. Write an exponential equation for each coin that will give the coin's value, V, at any time, t. Use the formula:
V(t) = P(1 + r)t, where V(t) is the value of the coin in t years, P is the initial investment, and r is the growth rate.
Coin A worth $25 and increase by 7% each year and coin B worth $40 increase by 5% each year
9514 1404 393
Answer:
V(t) = 25(1.07^t)V(t) = 40(1.05^t)Step-by-step explanation:
Put the given numbers into the given formula. It can be simplified a little bit.
Formula:
V(t) = P(1 + r)^t
Coin A
P = 25, r = .07
V(t) = 25(1.07^t)
Coin B
P = 40, r = 0.05
V(t) = 40(1.05^t)
The problem has been started for you. 8 StartLongDivisionSymbol 468 EndLongDivisionSymbol minus 40 = 68. 68 minus 64 to get a remainder of 4 and a quotient of 58. What is the quotient?
Answer:
Quotient = 58
Step-by-step explanation:
We are to find the quotient of the expression using long division method. This is as shown in the attachment.
The expression is expressed as;
468/8
This can be expressed as ;
468/8 = 58 + 4/8
Note that according polynomials are expressed as;
P(x) = Q(x) + R(x)/D(x)
Where;
Q(x) is the quotient
R(x) is the remainder
D(x) is the divisor
Comparing with the expression 58 4/8, you will see that Q(x) is 58.
Hence the quotient when 8 is divided by 468 is 58.

A water tank already contains 55 gallons of water when Baxter begins to fill it. Water flows into the tank at a rate of 8 gallons per minute. Write a linear equation to model this situation. How long it will take to get 127 gallons of water
Answer: 8x+55=127
Step-by-step explanation: it would take 9 mins because there’s already 55 gallons of water in the tank so you subtract that from 127 which is 72 then you divide 72 by 8 and get 9
