Answer:

The number is 240

Step-by-step explanation:

Is means equals and of means multiply

30 = 12.5% * N

Change to decimal form

30 = .125 N

Divide each side by .125

30/.125 = .125N/.125

240 = N

Factor 48m - 80n. 16mn(3m - 5n) 16(5n - 3m) 16(3m - 5n)

aliya0001 [1]

The correct answer for this would be the last option. The factors of 48m - 80n are 16(3m - 5n). If you try to solve this, the result would be 48m - 80n. 16 x 3m would be 48m and 16 times 5n would be 80n. Hope this is the answer that you are looking for.

Complete Question:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?

A. The distance traveled depends on the number of hours traveled.

B. The number of hours traveled depends on the speed of the train.

C. The speed of the train depends on the distance traveled.

D. The speed of the train depends on the number of hours traveled.

Answer:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. The distance traveled depends on the number of hours traveled

Step-by-step explanation:

As we know the velocity can de defined as the rate of change of position of objects in a particular time. The formula is given by,

$\text {velocity}=\frac{\text {distance}}{\text {time}}$

Here, in the question, rate of speed of train is given as 45 miles per hour. if we keep the velocity as constant one, then distance is directly proportionate to the travelled time

$\text {distance}=\text {velocity} \times \text {time}$

If 'v' is constant,

$\text {distance} \propto \text {time}$

By this we can conclude that, the distance travelled by the train depends on the time taken to travel to it. Hence option A would be the correct one.
