Answer:
Height = 250km
Step-by-step explanation:
Given,
rate of rise of ballon 1 = 38 km/h
rate of rise of ballon 2 = 50 km/h
Let the time after which both the ballons will reach same height be 't'.
hence, after 't' hours,
⇒ height of ballon 1 = height of ballon 2
⇒ 38t + 60 = 50t
⇒ 12t = 60
⇒ t = 5 hours
so, the height at which both the ballons will be at the same height will be 250km.
It helps immensely if you know the formula for the area of a sphere.
Area of a sphere = (4 π) (radius)² . . . . . for ANY sphere.
If the radius is 5-ft, then Area = (4 π) (5)² = 100 π = 314.16... square feet (rounded)

I NEED HELP! What are the dimensions of the rectangle shown below? Remember to use the axes on the coordinate grid to help you.
A coordinate grid is shown with scale from negative 14 to 0 to positive 14 on both x- and y-axes at increments of 2. A figure ABCD is shown with A at ordered pair negative 4, 4, B at ordered pair 10, 4, C at ordered pair 10, negative 4, and D at ordered pair negative 4, negative 4.
