Answer:
The quotient of a number and 9 means n divided 9.
First you are going to solve for f.
6f = -2
you must get f alone so you divide both sides of the equation by 6 which becomes ....
f = -3
now you add the absolute value sign to -3. absolute value is how far away your answer is from 0. -3 is 3 away from zero so f = 3
In 3 hours, the two planes will be 2,700 miles apart.
If in one hour, the planes get 900 miles apart, it will take 3 hours to become 2,700 miles apart.
《----- and -----》 Indicatethe planes moving in opposite directions.
The number indicate the distance traveled.
The amount of times the number is repeated indicates the amount of hours flown (ex.: 50+50+50+50 would indicate 4 hours flown because there are 4 50s in the sequence).
So
《-----300 + 600-----》
=900 miles in one hour
《------300+300 and 600+600-----》
=1,800 miles in 2 hours
《-----300+300+300 and 600+600+600-----》
=2,700 miles in 3 hours
Answer:
$36.25
Step-by-step explanation:
Surface area: 2*l*w+2*w*h+2*h*l
2*2*2.5+2*2.5*0.5+2*0.5*2
10+2.5+2
14.5 sq. ft.
14.5*2.50=36.25
