A^2 + b^2 = c^2
8^2 + b^2 = 11^2
64 + b^2 = 121
b^2 = 121 - 64
b^2 = 57
b = sqrt 57
b = 7.54 rounds to 7.5 ft <==

Answer: the employee must make sales of $32000
Step-by-step explanation:
Let x represent the total sales that the employee makes in a month.
One employee of a computer store is paid a base salary of $2,000 a month plus an 8% commission on all sales over $7,000 during the month. This means that if the employee makes sales of $x in a month, his total earnings for that month would be
2000 + 8/100(x - 7000)
= 2000 + 0.08(x - 7000)
= 2000 + 0.08x - 560
= 0.08x + 1440
Therefore, for the employee to earn
a total of $4,000 for the month, the amount of sales would be
0.08x + 1440 = 4000
0.08x = 4000 - 1440
0.08x = 2560
x = 2560/0.08
x = $32000
Answer: 31 ft
Step-by-step explanation: Add all of the sides together. So 5 1/3 + 5 1/3 + 10 1/6 + 10 1/6. Convert to the same denominator (6). 5+5+10+10=30. 2/6+2/6+1/6+1/6=1. And 30+1=31
