We have been given that Naima's pedometer recorded 43,498 steps in one week. Her goal is 88,942 Steps. Naima estimates she has about 50,000 more steps to Meet her goal.

We are asked to find out whether Naima's estimate is reasonable or not.

Let us find the number of exact steps to be completed by Naima to meet her goal.

Steps to be completed by Naima =88942-43498=45444

We can see that Naima's estimate is reasonable as it quite close to 50,000. But we can say that her estimate is not accurate, instead it is slightly over-estimated.

Quadrilateral ABCD is similiar to quadrilateral EFGH. The lengths of the three longest sides in quadrilateral ABCD are 24 feet,
MatroZZZ [7]

The two quadrilaterals are given similar .

In any similar figure sides are in proportion.The second largest side of quadrilateral ABCD is 16 ft .Let the second longest side of quadrilateral EFGH be x ft. These sides will be in proportion to each other .

The second shortest side of quadrilateral EFGH that is GF will be proportional to the third longest side of quadrilateral ABCD that is BC

We can form a proportion with the proportional sides:

\frac{16}{x} =\frac{12}{18}

To solve for x we cross multiply

12x=(16)(18)

12x=288

Dividing both sides by 12 we get

x=24.

The second longest side of quadrilateral EFGH is 24 ft.
