Again I need help, sorry but thank you!
musickatia [10]

Answer:

B)13 pints

Step-by-step explanation:

SO first we find the unit rate

We know that in 90 minutes (hour and a half), the water leaked 6 pints form 2;30 to 4

Now So we can divide to find unit rate

6/90=1/15

So 1 pint for every 15 minutes

And now we want to know the amount it takes from 2:30 to 6:30 which is 4 hours

40 hours is 240 minutes

SO we can divide now

240/15=16

SO 16 pints leaked but the question asked for remaining water in container

So 29-16 is 13

So B)13

What is the scale factor in the dilation ?<br><br>1/6<br><br>1/3<br><br>3<br><br>6​
anzhelika [568]

Answer:

3

Step-by-step explanation:

<u>1) Find two corresponding lengths between the image and the pre-image</u>

Pre-image (bottom side) = 3 units

Image (bottom side) = 9 units

We can use any corresponding lengths for this step.

<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>

9 units ÷ 3 units

= 3

Therefore, the scale factor of the dilation is 3.

I hope this helps!
