Lelechka [254]

Answer:

The T = \frac{18}{m} best models the amount of time it takes him to finish with kelvin cycling .

Option (A) is correct.

Step-by-step explanation:

As given

Kevin cycles 18 miles every morning as part of his exercise.

The time it takes him to complete the distance varies inversely as the speed at which he rides.

Time \propto \frac{1}{Speed}

Time = \frac{Distance}{Speed}

As m miles per hour is represented the speed.

T is the time taken by Kevin cycle for morning exercise .

Distance = 18

Putting the values in the above

T = \frac{18}{m}

Therefore the T = \frac{18}{m} best models the amount of time it takes him to finish with kelvin cycling .

Option (A) is correct.

mario62 [17]

Answer:

(x+1)(17a-1)

Step-by-step explanation:

We are given that

17ax+17a-x-1

We have to factorize the given expression.

Pair up the terms

(17ax+17a)+(-x-1)

Now, taking common factor

17a(x+1)-1(x+1)

Taking common (x+1)

(x+1)(17a-1)

Now, we get

(x+1)(17a-1)

This is required factors of given expression.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at miles 90 per
algol [13]
So the eastbound train travels at 90 miles per hour in the complete opposite direction to the westbound equivalent, which travels at 80 miles per hour. Therefore, per hour, they get 170 miles away from each other. Since we are working out how long it would take for them to be 204 miles apart:

204 / 170 = 1.2 Hours, or 1 hour and 12 minutes.

Hope I helped!
