18; 1h30m; 15

Step-by-step explanation:

Part A:

James traveled 45km, you can tell because that is where he stops.

It took him from 2pm to 4:30pm.

You can find this info on the x axis.

That means 45km took him 2.5 hours.

45/2.5=18

James travels 18km per hour.

Part B:

The stop is indicated by the flat part in the graph. This is because when he stops, the distance he is away from home is not changing.

His stop is from 4:30pm to 5pm.

This means that his stop is 1 hour and 30 minutes.

Part C:

James had to travel 45km to get back home. (45-0)

It took him from 5pm to 8pm.

This means that on his journey back, 45km took him 3 hours.

Katen [24]

Answer:

The area of the wall that she will paint in two rolls is 219.8 inches².

Step-by-step explanation:

Given:

Jenny uses a roller to paint a wall. The roller has a radius of 1.75 inches and a height of 10 inches.

Now, to find the area of the wall that she will paint in two rolls.

So, we find the lateral surface area of roller.

Radius (r) = 1.75 inches.

Height (h) = 10 inches.

So, to get the lateral surface area we put formula:

$A_{L} =2\pi rh$

$A_L=2\times 3.14\times 1.75\times 10$

$A_L=109.9\ inches^2.$

Thus, the lateral surface area of the roller = 109.9 inches².

Now, to get the area of wall that she will paint in two rolls we multiply 2 by the lateral surface area of the roller:

$109.9\times 2\\\\=219.8\ inches^2.$

Therefore, the area of the wall that she will paint in two rolls is 219.8 inches².
