Karen purchased the DVD

Answer:

Percent markdown = 14%

Step-by-step explanation:

Given:

Original price of DVD player = $175.90

Markdown price of DVD player =$153.77

To find percent markdown.

Amount of mark down $=\textrm{Original price - Markdown price}=\$175.90-\$153.77=\$22.13$

Percent markdown $=\frac{Amount\ of\ markdown}{Markdown\ price}\times100=\frac{22.13}{153.77}\times 100=14.39\%\approx 14\%$

a ladder leans against the sufe of a house. the angle of elevation of the ladder is 70 degrees when the bottom of the ladder is

nekit [7.7K]

Answer:

≈ 35.1 ft

Step-by-step explanation:

The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°

Using the cosine ratio, with l being the length of the ladder.

cos70° = $\frac{adjacent}{hypotenuse}$ = $\frac{12}{l}$ ( multiply both sides by l )

l × cos70° = 12 ( divide both sides by cos70° )

l = $\frac{12}{cos70}$ ≈ 35.1 ( to the nearest tenth )

The ladder is approx 35.1 ft long
