5/8 = .625
531.25 / .625 = 850
850 - 531.25 = $318.75
U divide 330 by 15 and get the quotient then do the same thing to 20 and add the quotients together to solve for x and y
Answer:
2. The change in expected height for every one additional centimeter of femur length.
Step-by-step explanation:
<u>1. The expected height for someone with a femur length of 65 centimeters.</u>
<em>Doesn't make sense, that would be height value when centimeters = 65.</em>
<u>2</u><u><em>. </em></u><u>The change in expected height for every one additional centimeter of femur length.</u>
<em>Makes sense, for every increase in one additional centimeter, we can expect the height to be proportional to the slope.</em>
<u>3. The femur length for someone with an expected height of 2.5 centimeters.</u>
<em>Doesn't make sense, the linear relationship relies on the femur length to get the height.</em>
<u>4. The change in expected femur length for every one additional centimeter of height.</u>
<em>Doesn't make sense, again, the linear relationship relies on the femur length.</em>
Explanation
We are given the following right-angled triangle:
We are required to determine the indicated angle in the given figure.
This is achieved thus:
According to the image, we have:
Therefore, we have:
Hence, the answer is:
