ELEN [110]

Answer:

$331.25

Step-by-step explanation:

Given:

The jewelry center bought a pair of earrings for $250

They are going to mark the price of the earrings up 32.5%

Question asked:

How much will they sell the earrings for ?

Solution:

Cost price of a pair of earrings =  $250

Mark up value = 32.5% of $250

                        = \frac{32.5}{100}  \times 250\\\frac{8125}{100} = 81.25

Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.

Selling price = cost price + mark up value

                     = 250 + 81.25

                     = $331.25

Thus, they sell the earrings for  $331.25

A ladder is placed 8 feet away from a wall. The distance from the ground straight to the top of the wall is 16 feet. What is the
elena-14-01-66 [18.8K]

Answer:

17.89 ft

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

8^2 +16^2 = c^2

64+ 256 = c^2

320 =c^2

Taking the square root of each side

sqrt(320) = sqrt(c^2)

sqrt(64*5) = c

sqrt(64) sqrt(5) =c

8 sqrt(5) = c

17.88854382=c

17.89 ft
