Answer: 1.) √121= 11
Step-by-step explanation:
11•11=121
6 pennies, 12 nickels, 8 dimes, 4 quarters = 30 coins
a) add the probability for drawing a dime and drawing a quarter together:
12/30 + 4/30 = 16/30 = 8/15
The probability is 8/15 or 53%
b) multiply the probability for drawing a penny and drawing a nickel:
6/30 x 12/30 = 72/900 = 2/25
The probability is 2/25 or 8%
c) multiply the probability for drawing quarters but take away one of the total coins and the amount of quarters each time:
4/30 x 3/29 x 2/28 = 24/24360 = 1/1015
The probability is 1/1015 or 0.099%

Answer: 23.80
Step-by-step explanation:
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
