Wanda, the owner of an e-commerce site, buys skateboards for $50 and then sells them on her site for $83. What is the mark-up, as a percentage?

Answers

Answer: 66%

Step-by-step explanation:

Wanda buys the boards at $50 and sells them as $83.

The markup in actual dollar amounts is:

= 83 - 50

= $33

In percentage terms, the denominator will be the cost price:

= Markup / Cost price * 100%

= 33 / 50 * 100%

= 66%

The equation for the price of a baseball card that was bought for 5 dollars and has appreciated 5% yearly. Find the yearly calue of the card 25 years later

Answers

Answer:

The yearly value of the card 25 years later is $16.93.

Step-by-step explanation:

You can use the following formula to find the future value:

FV=PV(1+r)^n

FV= future value

PV= present value= 5

r=rate= 0.05

n=number of periods of time= 25

Now, you can replace the values in the formula:

FV=5(1+0.05)^25

FV=5(1.05)^25

FV=16.93

According to this, the answer is that the yearly value of the card 25 years later is $16.93.

Find the hypotenuse.
(4 Points)

Answers

Answer:

x = 13

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

x = [tex]\sqrt{169}[/tex] = 13

Answer:

a²+b²=c²

5²+12²= c²

25+144=c²

169=c²

[tex] \sqrt{169 =} \sqrt{c} [/tex]
