in 2005, the total waste generated in a certain country was 3.474x10^9 pounds. also in 2005, the countrys population was 1.23x10

Serggg [28]

Answer:

2824

Step-by-step explanation:

Take the number of pounds and divide by the number of people:

3.474×10⁹ / 1.23×10⁶

Divide the coefficients and subtract the exponents:

(3.474 / 1.23) × 10⁹⁻⁶

2.824×10³

So the country produced about 2,824 pounds of garbage per person in 2005.

In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call $x$ ) and the length of the hypotenuse. This sets you up with the relation

$\sin2^\circ=\dfrac x{1600}\implies x\approx55.84\text{ m}$

In 23, you're given a similar situation, except now you're looking for the angle (I'll call it $\theta$ ) in the triangle opposite the side denoting the height of the airplane. So this time,

$\sin\theta=\dfrac{1500}{5000}=\dfrac3{10}\implies\theta=\arcsin\dfrac3{10}\approx17.46^\circ$
