What is the answer? What does the symbol mean??

madam [21]

Answer:

6 or -6

Step-by-step explanation:

The symbol √ is the square root symbol.

The square root of a number is a number that when you multiply it by itself you get the first number.

For example:

The square root of 9 is 3 since 3 times itself, 3 × 3, is 9.

The square root of 9 is also -3 since (-3) × (-3) is 9.

The question is asking for the positive and negative square roots of 36.

What number multiplied by itself is 36?

The answer is 6 since 6 × 6 = 36 and -6 × -6 = 36

Answer: 6 or -6

Ivan and Tanya share £150 in the ratio 4:1<br> How much more does Ivan get than Tanya

mina [271]

Answer:

Ivan gets £90 more than Tanya

Step-by-step explanation:

Given that

Total amount = £150

Ratio: 4:1

First of all we have to find the sum of ratio: 4+1 = 5

Now,

Ivan's Share:

$= \frac{4}{5} * 150\\= 120$

Tanya's Share:

$=\frac{1}{5} * 150\\= 30$

Ivan gets £120 and Tanya gets £30

The difference between their shares is the answer.

So,

$= 120-30 = 90$

Hence,

Ivan gets £90 more than Tanya
