Finding the greatest common factor ( or G C F ):
G C F is the largest number that divides evenly into all the numbers.
270 : 90 = 3
360 : 90 = 4
G C F ( 270, 360 ) = 90
Answer:
The solution of the given set in interval form is
.
Step-by-step explanation:
It is given in the question an inequality as
.
It is required to determine the solution of the inequality.
To determine the solution of the inequality, solve the inequality
and, 
Step 1 of 2
Solve the inequality 

Solve the inequality
.

Step 2 of 2
The common solution from the above two solutions is x less than -4 and
.
The solution set in terms of interval is
.
We know that
3600 seconds = 1 hour
Then
3400 seconds = 3400/3600
= 17/18 hours
5280 feet = 1 mile
Then
63360 feet = 63360/5280 mile
= 12 mile
So
Distance covered by Nina in 17/18 hours = 12 mile
Then
Distance covered by Nina in 1 hour = 12/(17/18) miles
= 12.71 miles.
From the above deduction, we can conclude that the speed of Nina is 12.71 miles per hour.
Speed of Sophia is 10 miles per hour. So Nina is the girl that rides at a faster speed.
The cost of water would be $615 as he needs 3 acre-feet of water for 205 acre/ft
The answer is -4 and 21
