Answer:

x = 35

Step-by-step explanation:

x = 35, because first you have to add all your like factors. Then you'd get 2x + 110 = 180, afterwards you'd subtract 110 from both sides. Then divide 2 on both sides. Leaving you with x = 35.

The angle of elevation to the sun is 24°. What is the length of the shadow cast by a person 1.82 m tall? A. 0.81 m B. 1.99 m C.

Zanzabum

Answer:

C. 4.09 m

Step-by-step explanation:

Let the length of the shadow cast by a person be x m.

$\tan \: 24 \degree = \frac{height \: of \: person}{length \: of \: the \: shadow} \\ \\ 0.4452286853 = \frac{1.82}{x} \\ \\ x = \frac{1.82}{0.4452286853} \\ \\ x = 4.08778693 \: m \\ x = 4.09 \: m$

Help with b please I don’t understand it

galben [10]

Answer:

This is a 25% decrease

Step-by-step explanation:

percent change = (old - new)/old * 100 %

The new price is 15

The old price is 20

Since the new price is less than the old price, it is a decrease

percent change = (20-15)/20 * 100 %

= 5/20 * 100%

=.25 * 100%

= 25%

This is a 25% decrease
