Yuliya22 [10]3 years ago
5 0

Answer:

4 students

Step-by-step explanation:

We can say that 20 students represent 100 % and that 4 students represent x % of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 % Answer: 4 students is 20 % of 20 students. Hope this helps. Let me know if you need additional help!

sattari [20]

Answer:

89 hours

Step-by-step explanation:

First solve all the deductions.

For each multiply the $10, which you are paid, and the percentage.

For FICA: $10 x 0.0765 = $0.77 per hr

For Fed tax: $10 x 0.12 = $1.2 per hr

For State tax: $10  x 0.08 = $0.8 per hr

Now subtract the remaining pay:

10 – 0.77 – 1.2 – 0.8 = $7.23

Time required = $640 / $7.23 per hr

Time required = 89 hrs

Final answer:

89 hours
