Answer:
58 seconds
Step-by-step explanation:
Given the following :
Elevation of red Kite = 140 ft off the ground
Rising rate = 7 feets per second
Elevation of blue Kite = 315 feets
Rising rate of blue Kite = 4 feets per second
Determine how long will it take for the red and blue kites to be the same height.
Let number of seconds = t
Red Kite = 140 + 7t
Blue Kite = 315 + 4t
Red Kite = Blue Kite
140 + 7t = 315 + 4t
7t - 4t = 315 - 140
3t = 175
t = 175/3
t = 58.333
t = 58s (nearest tenth(

Answer:
Volume= 82.4in³
Step-by-step explanation:
Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid. It's units are always "cubic"
To find the volume of sphere, we will use the following formula of Volume:
Volume = 4/3 πr³
Put the values in the formula:
As we know that the value of π is 22/7 or 3.14
Radius = 2.7
According to the formula:
Volume = 4/3 * 3.14 *(2.7)³
Volume= 4/3* 3.14(19.683)
Volume=4/3(61.80462)
Volume=247.21848/3
Volume= 82.4in³....
