If you take the square root of every whole number from 1 through 100, how

Lady_Fox [76]

Only numbers 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100 will come out to be whole numbers.

Meaning, that 10 are whole numbers and the other 90 are not.

PLEASE HELP I WILL GIVE BRAINLIEST TO THE FIRST PERSON THAT ANSWER PLEASE

Answer:

$a) x = k \times \frac{1}{y^2} \ , \ where \ k \ is \ a \ constant\\\\b) x = 3, \ when\ y\ =\ 10\\\\c) y = 10, \ when \ x = 3$

Step-by-step explanation:

a)

$x \ \alpha \ \frac{1}{y^2}\\\\x = k \times \frac{1}{y^2}\\\\$ $[ \ where \ k \ is \ a \ constant \ ]$

<em><u>Find k.</u></em>

Given x = 12, y = 5,

$12 = k \times \frac{1}{5^2}\\\\k = 12 \times 25 = 300$

b)

<em><u>Find x.</u></em>

Given y = 10

We have k = 300

$x = k \times \frac{1}{y^2}\\x = 300 \times \frac{1}{10^2} \\\\x= \frac{300}{100} = 3$

c)

<u><em>Find y</em></u>

Given x = 3

We have k = 300

$x = k \times \frac{1}{y^2}\\\\3 = 300 \times \frac{1}{y^2}\\\\\frac{1}{y^2} = \frac{3}{300}\\\\\frac{1}{y^2} = \frac{1}{100}\\\\y^2 = 100\\\\y = \sqrt{100} = 10$
