40% of the children in a sports club play badminton. 25% of the children who play badminton also play squash. There are 11 child
Keith_Richards [23]

Answer:

There are 110 children total in the sports club

Step-by-step explanation:

To get this answer, its actually easier than it seems. You might need a calculator however.

First you start with the 11 children who play both badminton and squash, then, you divide that by 0.25 (25%) to get 44.

Next you take 44 and divide it by 0.4 (40%) to get 110.

And there you go! If you want to make sure you got it right simply start with 110 and multiply it by 0.4 then multiply the number/decimal you get by 0.25. You should get 11 to confirm your answer :)

How to do this question plz ​
enyata [817]

Answer:

  x = 10

Step-by-step explanation:

Use the Pythagorean theorem. The sum of the square of the sides is the square of the hypotenuse.

  x² +(√200)² = (√300)²

  x² = 300 -200

  x = √100 = 10

The length of the unknown side is 10 units.

10 times as many as a number is 10 × the number.

10 times as many as 1 ten is 10 × 10 = 100

10 times as many as 1 hundred is 10 × 100 = 1000

Therefore, 10 times as many as 1 hundred is 10 hundreds or

10 times as many as 1 hundred is one thousand.
