D = 0.5gt^2
2d = gt^2
g = 2d/t^2
when t = 10 s, and d = 490 feet,
g = 2(490)/10^2 = 980/100 = 9.8 feet/s
You will have to make the fraction a decimal first by dividing the top number by the bottom number then divide if your other number is already a decimal/whole number

Answer:
5^5-7^2= 3076
Step-by-step explanation:
5^5=3125
5*5*5*5*5

Answer:
120 miles
Step-by-step explanation:
Formulate equations.
Distance = rate * time.
D1 = distance from home to airport
D2 = distance from airport to off
D1 + D2 = 150
30 x t1 + 60 x t2 = 150
Divide through by 30
t1 + 2t2 = 5 ----- equation 1
Entire trip took 3 hours
t1 + t2 = 3 -------------------- equation 2
Solve equation 1 and 2 and you get
t1 = 1 hour
t2 = 2 hour
D2 = t2 x speed = 2 x 60
= 120 miles.
