a set B consists of all natural numbers (counting numbers) less than or equal to 100. Use set-builder notation to define B.
Arada [10]

Answer:  The required set-builder notation is :

B=\{x:x\epsilon \mathbb{N},x\leq 100\}.

Step-by-step explanation:  We are given to write the following set B in set-builder form :

the set B consists of all natural numbers less than or equal to 100.

In set-builder form, a variable x is used to represent each and every element of the set.

Therefore, the set B in set-builder form can be written as :

B=\{x:x\epsilon \mathbb{N},x\leq 100\}.

Thus, the required set-builder notation is :

B=\{x:x\epsilon \mathbb{N},x\leq 100\}.

A swimming pool containing 2000l of water is 1/16 full. How many litres of water is required to make the pool half full
liq [111]

Answer: 16,000 litres

Step-by-step explanation:

1/16 of the pool is 2000l

8/16 full is 1/2 of the pool full

1/16 = 2000

8/16 = x

Cross multiply

1/16x = 2000 × 8/16

1/16x = 1000

Multiply both sides by 16

x = 16000

To make the pool half full, 16,000 litres is required.
