The Clark family has a hallway that perimeter is 10and4/10 then they add that shortens the length of hallway what is the new perimeter? A. 3 3/10 B.6 6/10 C.9 2/10 D.9 8/10

C. 9 2/10

Step-by-step explanation:

Because it measures 10. And we cut 4/10 in length, therefore, this value is decreased twice so that it remains a rectangle.

Then it would be:

10 - 2 * (4/10) = 10 - 8/10 = 9.2

And this 9.2 we can express it as a mixed number as follows:

9.2 = 9 2/10

If we check, we know that 2/10 = 0.2 that added to 9, would be equal to 9.2

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
