The surface area of a swimming pool is 373 square feet. What is it’s surface area in square meters?

jeka57 [31]

The surface area of swimming pool is 373 square feet .

In this question, we have to convert square feet to square meters, that is

$1 feet = 0.3048 meter$

Squaring both sides ,

$1 feet^2 = 0.3048^2 meter^2$

$1 feet ^2 = 0.09290304 meter^2$

And

$373 feet^2 = 373* 0.09290304 meter^2$

$373 feet^2= 34.653meter^2$

The sum of two numbers is 36. Twice the first number minus the second 6. Find the number.

just olya [345]

Answer:

14 AND 22

Step-by-step explanation:

LET THE LARGER NUMBER BE X AND SMALLER BE Y

X + Y = 36 …….1

2X – Y = 6…… 2

WE SOLVE SIMULTANOUSLY

ADDING EQATION 2 AND 1

2X + X + Y + (-Y) = 36 + 6

3X + Y – Y = 42

3X = 42

DIVIDING EACH TERM BY 3

3X/3 = 42/3

X = 14

THEN PUTTING X = 14 IN EQUATION 1

14 + Y = 36

Y = 36 – 14

Y = 22
