Answer:
1 kilometer = 0.621371 mile
mile = kilometer * 0.621371
Step-by-step explanation:
Answer:
calculus, geometry, arithmetic among a few
Step-by-step explanation:
Mathematics is involved in winter Olympics in different aspects like arithmetic which helps in scores, measurements, quantities and motion of the sport like hockey, running.
Scoring in ice skating involves arithmetic operation when an individual element is assigned points and judged on performance level( triple axle is 3 points but overall performance and artistry is measured by the judges).
Another is Calculus which helps to understand the change in acceleration and velocities while each skaters start at zero then win, Lines in Geometry such as the finish/start/sight lines helps players with angles of reflection, measuring angles and angles of incidence.
80, divide 200 by 2.5 and you get 80. Check by multiplying 2.5 and 80, which equals 200
Multiplication should be used here. 30 tens means number ten should be
added 30 times. 10+10+...+10 thirty times, which can be written as 10 x
30 which gives us the number 300. We get the same answer if the value of
10 thirties is required. We can use the same way to get the answer like
the question given in the begging.

Given:
average of five numbers is 16 and four of the number are 12 , 14, 16 and 18
To find:
the remaining number
Solution:
The given numbers are 12,14,16,18
Let the another number be X
Sum of five numbers = 12+14+16+18+X
=60+X
Average of five numbers =16
Average= Sum of observations/no.of
observations
=>16=(60+X)/5
=>(60+X)/5=16
=>60+X=5×16
=>60+X=80
=>X=80-60
=>X=20
Answer:
The fifth number is 20
