Answer:
<u>v = √(LT/m)</u>
Step-by-step explanation:
Given :
Multiply both sides with L :
- T × L = mv²/L x L
- LT = mv²
Divide both sides by m :
- LT × 1/m = mv² × 1/m
- LT/m = v²
Take the square root on each side :
- √v² = √(LT/m)
- <u>v = √(LT/m)</u>
1 inch= 2.54 cm
Divide 7 by 2.54.
7/2.54= 2.75591
So, 7 cm is about 2.8 inches. (rounded up)
I hope this helps!

Adam pays for 2/5 of the meal so his father pays for 3/5
3/5 = 52.50
1/5 = 52.50 / 3 = 17.50
so cost of the meal = 5 * 17.50 = $87.50
