Shelia is going to divide a 36-inch ribbon in piece of 5 equal parts. she says each piece will be 7 inches long. what is sheila's error?

Given that,

The length of ribbon= 36 inch

We know, if Shelia wants to divide the ribbon in 5 equal parts, she needs to divide the length of the ribbon by 5.

So,

The length of the 5 equal parts of the ribbon= 36/5= 7.2 inch

But Shelia got each pieces length equals to 7 inches.

So, There is an error of (7.2-7) 0.2 inches in her calculation.

this is false ^.^ lol

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
