Answer: 9/25 or 36%
Step-by-step explanation:
72 + 28 + 62 + 38 = 200
There are 200 people in total and 72 are youngsters who like sport cars.
So, the number of youngsters who like cars out of the total number of people is 72/200.
Now, find a greatest common divisor. In this case, the greatest common divisor is 8.
72 / 8 = 9
200 / 8 = 25
9/25 (fraction)
25 * 4 = 100
9 * 4 = 36
36/100 = 36% (percentage)
The measurement of D can be anyone one of these but where's the rest of the problem like a pic or the measurements of any other angles?
Since 15 workers did 8 hours of work, the total amount of work needed is 120 hours. Half of this job would be 60 hours. Then divide this amount by the 5 workers doing the job. This would make the job 12 hours
Answer:
C, -4
Step-by-step explanation:
slope=change in y/change in x
![\frac{2 - y}{5 - ( - 10)} = \frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20-%20y%7D%7B5%20-%20%28%20-%2010%29%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B5%7D%20)
![\frac{2 - y}{5 + 10} = \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20-%20y%7D%7B5%20%20%2B%2010%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B5%7D%20)
multiply both sides by 2/5
![2 - y = \frac{2}{5} (5 + 10)](https://tex.z-dn.net/?f=2%20-%20y%20%3D%20%20%5Cfrac%7B2%7D%7B5%7D%20%285%20%2B%2010%29)
simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4
![2 - y = 2 + 4](https://tex.z-dn.net/?f=2%20-%20y%20%3D%202%20%2B%204)
![2 - y = 6](https://tex.z-dn.net/?f=2%20-%20y%20%3D%206)
bring y to the other side by adding y on both sides
![2 = 6 + y](https://tex.z-dn.net/?f=2%20%3D%206%20%2B%20y)
subtract 6 on both sides
![2 - 6 = y](https://tex.z-dn.net/?f=2%20-%206%20%3D%20y)
so y is -4
