Explanation:
From the tape diagram, we can deduce the following;
*Total number of items = 87
*Number of subdivisions = 5 with one of them being a group of 39
Let's see which of the given stories that the tape diagram can represent;
A) Total number of first graders = 87
Students picked up = 39
Number of groups the remaining students were divided into = 4
We can see from the above that the tape diagram can represent this story
B) Number of children at the show = 87
Number of adults at the show = 39
Total number of people at the show = 87 + 39 = 126
We can see from the above that the tape diagram can not represent this story
C) Number of packs of pencils Lin bought = 87
Number of packs she gave to her teacher = 39
She then shared the remaining packs between herself and 3 friends
We can see from the above that the tape diagram can represent this story
D) Total amount Diego's family spent to a fair = $87
Amount spent on dinner = $39
They spent the remaining spent on 4 tickets
We can see from the above that the tape diagram can represent this story
E) Number of packs of paper clips Adre bought = 4
Number of paper clips in each = 39
Total number of paper clips bought = 39 x 4 = 156
We can see from the above that the tape diagram can not represent this story
Answer:
x =
Step-by-step explanation:
Given,
Squaring on both L.H.S. and R.H.S.
By expanding L.H.S. we get x² + 49
By expanding R.H.S. we get x² + 10x + 25
x² + 49 = x² + 10x + 25
x² will be subtracted:
49 = 10x + 25
Variables are to be arranged:
10x = 49 - 25
10x = 24
x =
∴ x =
So it would be 9 x 3.14 x 10 OR <span>282.6</span>
