Answer:

Choice B) No.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.

Answer:

  ? = 9

Step-by-step explanation:

The segments of each of the transversals are proportional. On the left side, the bottom transversal segment will be 10 -6 = 4 units in length.

Now we can write a proportion relating right-side transversal segments to left-side transversal segments:

  ?/6 = 6/4

  ? = 6(6/4) = 36/4 = 9

The missing length is 9 units.

Michelle is building shelves for her room. She has a plank 137 inches long that she wants to cut into 7 shelves of equal length.
ipn [44]
I think that each shelf will be 19 inches.  Because 137 divided by 7 is 19 with the remainder of 4.  Half of 4 is 2. Take 2 inches off of each end and that is the 4.  So each shelf is 19 inches.
