Answer:
Length = 120 ft
Total cost = 1500$
Step-by-step explanation:
First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.
10,800 ft^2 / 90 ft = 120 ft.
we can check this by plugging the length of 120 ft into the formula:
120 ft * 90 ft = 10,800 ft^2.
Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):
120 * 12.50 = $1500
Answer:
Sessions needed= 12
Step-by-step explanation:
Giving the following information:
Total hours= 12 hours
Practice= 3/4= 0.75 of an hour
Already practiced= 3 hours
<u>First, we need to determine how many minutes does she practice each session:</u>
Minutes per session= 0.75*60= 45 minutes
<u>Now, we divide the total practice in minutes required for the minutes per session:</u>
Sessions needed= (9*60) / 45
Sessions needed= 12
