A computer downloads 30 megabits per second for "t" seconds. Write an equation to represent the number of megabits, m, downloaded.

M = 30t

Step-by-step explanation:

Given that a computer downloads 30 megabits per second for "t" seconds. That is, the rate at which the computer downloaded it is 30 megabits/second

Where time = t seconds

To Write anequation to represent the number of megabits, m, downloaded,

Rate = megabits/ time

Where

Rate = 30

Megabits = m

Time = t

Therefore, substitute all into the formula

30 = m/t

Make m the subject of formula

M = 30t

The equation is m = 30t

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
