X is equal to 10 and y is equal to 2.
Answer:
10 %
Step-by-step explanation:
15 mn = 1/4 h
We have :
![\frac{\frac{1}{4} }{\frac{5}{2} } =\frac{1}{4} \times \frac{2}{5} =\frac{2}{20} =\frac{1}{10}=0.1](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%7B%5Cfrac%7B5%7D%7B2%7D%20%7D%20%3D%5Cfrac%7B1%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7B2%7D%7B5%7D%20%3D%5Cfrac%7B2%7D%7B20%7D%20%3D%5Cfrac%7B1%7D%7B10%7D%3D0.1)
Then the percentage that 15 mn represents of 5/2 h is :
0.1 × 100 = 10 %
Let m = the total number of medals.
To find the total number of medals we can use either of the clues they gave us.
If Tara's team received 8 medals and that was 1/3 of the medals. That must mean that:
m x 1/3 = 8
What number divided by 3 is 8? Well, that is 24. Thus, the total number of medals is 24.
Note: we can check to see if 1/2 of 24 is 12, the total number of medals Jennifer team received, and it checks out!
Michael's initial investment is $45.80, the cost of the share.
Michael Receives $1.71 in dividends.
He receives $47.50 for the stock when he sells it.
His profit on the sale of the stock is $47.50 - 45.80 = $1.70.
His total return on the stock is his total earnings, the dividends plus his profits on the sale of the stock, divided on what he paid initially, $45.80:
(1.71 + 1.70) ÷ 45.80 = .0744 = 7.45%
7.45% return on investment in less than a year, not bad!
Closest answer is 7.7%, not sure why it isn't exactly 7.45 or 7.5%.
Answer is B) 7.7%
