Answer:
Step-by-step explanation:
n = 3
3(n + 2) = 3(3+2) = 3*5 = 15
1 length is 4.75 feet
42 lengths = x feet Cross multiply
1 * x = 42 * 4.75 Multiply on the right
x = 199.5
amount left = amount started with - amount amount used
Amount left = ???
Amount started with = 240 feet.
Amount used = 199.5 Substitute
Amount left = 240 - 199.5 Subtract
Amount left = 40.5 Answer
Answer: no
Step-by-step explanation:
The ratio is 91/120 because 91 is only divisible by 1, 7, 13, 91 and 120 is not divisible by 7, 13, or 91 so you cannot reduce this ratio
Answer: 1/20
Step-by-step explanation: = 1+8:36= 9 hours and 36 minutes
= 9+ 36/60= 9 3/5 hours
=48/5
Decrease per hour= 12/25 divided by 48/5
= 12/25 times 5/48= 1/20
Ans 1/20
