Answer:
25 seconds
Step-by-step explanation:
The radius of a hailstorm varies directly
with the amount of time that it was in a cloud.
Radius = k x Time (in the cloud)
k is the constant of proportionality
R = k x T
0.5 = k x 10
k = 0.5/10
k = 0.05
Formula: R = 0.05 x T
1.25 = 0.05 x T
Time = 1.25/0.05
Time = 25 seconds.
Hope this helps :) !
Step-by-step explanation:
the volume of a cube is
side³.
since the volume is 27 m³, the individual side lengths are then the cubic root of 27 = 3 m.
the surface area is 6 squares of 3×3 = 9m², so in total
9 × 6 = 54 m²

Example Equation of an ellipse with horizontal major axis with center at (0,0):
x%5E2%2Fa%5E2%2By%5E2%2Fb%5E2=1
For given problem:
b=20
b^2=400
a=30
a^2=900
equation: x%5E2%2F900%2By%5E2%2F400=1
y%5E2%2F400=1-x%5E2%2F900
