Valeria drives 500 meters up a hill that makes an angle of 15 degrees with the horizontal. to the nearest tenth of a meter, what horizontal distance has she covered?

Approximately 485 meters

Step-by-step explanation:

We can first construct a right triangle, using the 500 m length of hill as our hypotenuse. Using the fact that the cosine of an angle is the ratio of the adjacent side to the hypotenuse, we see that

where x is the horizontal distance covered. Solving for x, we find this horizontal distance to be

so our answer is approximately 485 m.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

1/800 is the right answer
