Elena L [17]

Answer:

8,820m

Step-by-step explanation:

Let m be meters

We will have to find the amount of seconds in half an hour

60 * 30

= 1,800

Then we will multiply the meters she walks per second by 1,800

3.4m * 1,800

= 6,120m

1.5m * 1,800

= 2,700m

We add those two together to get the total walked in an hour

6,120m + 2,700m

= 8,820m

What is the percentage increase of a room that is the size of 96 square feet to a room that is 108 square feet?
katrin [286]

Answer:

12.5% increase OR 112.5% Percentage of Change

Step-by-step explanation:

For this problem consider that our original maximum value is 96 square feet, but our new maximum value is 108 square feet. So to find the change as a percentage (in this case the increase) use the following formula:

Percentage of Change = ( New Maximum / Old Maximum ) * 100

So, let's use this formula to find the percentage change of the room.

Percentage of Change = ( 108 / 96 ) * 100

Percentage of Change = (1.125) * 100

Percentage of Change = 112.5

So the percentage of Change is 112.5%. Note, the old maximum is the point of comparison which is 100%.

So to find the increase, we will do 112.5% - 100% to get 12.5%. Hence, we have a 12.5% increase of a 108 square foot room compared to a room of 96 square feet.

Cheers.

Aaron gets paid 152.80 for 8 hours of work how much does he make per hour ?
Dvinal [7]

To find out how much money Aaron makes an hour, all we have to do is divide

152.80 ÷ 8 = 19.1

Let’s check our work:

19.1 x 8 = 152.8

Therefore, Aaron makes $19.10 per hour

Hope this helps!
