Answer:
Total profits = 49.50n
Step-by-step explanation:
Cost of each quilt = $30.50
Selling price of each quilt = $80
Profits = selling price - cost price
= $80 - $30.50
= $49.50
Profits = $49.50
If n = number of quilts she sells
which expression could be used to represent her total profits?
Total profits = profits of each quilt × number of quilt sold
= $49.50 × n
= 49.50n
Total profits = 49.50n
Here is the work for that problem
Rachel fills 13 water bottles per hour, so she contributes 13R. Alyssa fills 15 bottles an hour, so she contributes 15A, plus 5 for the additional water bottles filled. Thus, the full expression is:
13R+15A+5
Answer:
Brent spent $47.46 on his co-workers
Step-by-step explanation:
7.91 times 6
For this case we have the following function:
f = 1 / (2π√LC)
Clearing L we have:
√LC = 1 / (2πf)
LC = (1 / (2πf)) ^ 2
L = (1 / C) * (1 / (2πf)) ^ 2
Substituting values:
L = (1 / 0.0001) * (1 / (2 * 3.14 * 6.2)) ^ 2
L = 6.596253438
Round to the nearest tenth:
L = 6.6
Answer:
L = 6.6
