John is 1 8 meter shorter than Paul, and Paul is 0.25 meter taller than Andrew. If John’s height is 1 3 4 meters, what is Andrew

9966 [12]

Answer:

Andrew's height is $1\frac{5}{8}$ meters

Explanation:

We know that John's height is $1\frac{3}{4}$ meters

We are given that:

John is $\frac{1}{8}$ meters shorter than Paul

This means that:

Paul's height = John's height + $\frac{1}{8}$

Paul's height = $1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8}$ meter

We are given that:

Paul is 0.25 meters taller than Andrew

This means that:

Andrew's height = Paul's height - 0.25

Andrew's height = $1\frac{7}{8} - 0.25 = 1\frac{5}{8}$ meters

Hope this helps :)

There are 100 runners entered in a marathon. How many different groups of three runners can finish in first, second, and third?

Lelu [443]

Any one of the runners could be 1st.
Every runner except for the one that was 1st could be 2nd.
Every runner that wasn't 1st or 2nd could be 3rd.

100*99*98=970200 groups.
This involves permutations because order does matter.

Hope this helps!
