Answer:
15,840 feet.
Step-by-step explanation:
We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.
Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.



Therefore, Maureen walked 15,840 feet.

Answer:
A
Step-by-step explanation:
Answer:
Use 49 ounces of the 14% allow and 41 ounces of the 23% alloy.
Step-by-step explanation:
Each ounce of the 14% copper contains 0.14 ounce of pure copper.
Each ounce of the 23% copper contains 0.23 ounce of pure copper.
Each ounce of the 18.1% copper contains 0.181 ounce of pure copper.
Use x ounces of the 14% and y ounces of the 23% to make 90 ounces of 18.1% alloy.
x+y = 90
y = 90-x
0.14x + 0.23y = 0.181·90
0.14x + 0.23(90-x) = 16.29
0.14x + 20.7 - 0.23x = 16.29
-0.09x + 20.7 = 16.29
4.41 = 0.09x
x = 49
y = 90-x = 41
Use 49 ounces of the 14% allow and 41 ounces of the 23% alloy.
