Answer: 2 19/24 hours was spent in practising.
Step-by-step explanation:
During the first hour, they practiced for 5/8 of an hour. During the second hour, they practiced for 2/3 of an hour. This means that the total time for which they practiced in the first 2 hours would be
5/8 + 2/3 = 31/24 hours
During the last two hours, they first practiced for 3/5 of an hour, took a 1/2 hour break and then practiced the rest of the time. This means that the rest of the time for which they practiced is
2 - (3/5 + 1/2) = 2 - 11/10 = 9/10
Therefore, the time they spent practicing in total would be
31/24 + 3/5 + 9/10 = 67/24 =
2 19/24 hours
Answer:
4
Step-by-step explanation:
N=8
If you set 2/3 equal to n/12 then you multiple 3 by 4 to get 12. So you have to multiple 2 by 4 to get N.
Answer:
Distance = abs(-1700)
Distance = 1700 miles
Step-by-step explanation:
NYC is located East of Los Angels.
The Airplane flies from Los Angeles to the left direction from NYC.
Which is negative direction.
Therefore, distance = -1700
Here the distance cannot be negative even though if it flies in negative direction.
Therefore, we use the absolute value.
The absolute value of a number is always positive.
So, distace = abs( -1700)
Distance = 1700 miles.
Hope this will help you understand the concept.
Thank you.
A, B and C but I’m contemplating D too but it’s def not E or F
