Answer: The correct option is
(C) 7.7 cm.
Step-by-step explanation: Given that two rectangles are similar. One has a length of 11 cm and a width of 10 cm, and the other has a width of 7 cm.
We are to find the length of the second rectangle.
Let l represents the length of the second rectangle.
We know that the corresponding sides of two similar rectangles are proportional.
So, we must have

Answer:
$491.65
Step-by-step explanation:
The pay for the first 8 hours is $5.40 per hour × 8 hours = $43.20. Hours over 8 are paid at 1.5 × $5.40 = $8.10 per hour. There are at least 8 hours every day for the 6-day week. There are hours over 8 on Monday, Wednesday, Thursday, and Friday totaling 7 hours of overtime.
The amount of sales is more than $3000, so 4% will be paid on $3000, and 5% will be paid on the $1115 in excess of $3000.
So, the gross pay is ...
$43.20 × 6 + 8.10 × 7 = $315.90 . . . . wages
$3000 × .04 +1115 × .05 = $175.75 . . . commission
$315.90 +1.75.75 = $491.65 . . . . gross pay for the week
