' of ' means ' times '.
0.45 times 'x' = 200
Divide each side by 0.45 : x = 200/0.45
x = 444 and 4/9 .
(45/100)x=200
x=(200*100) / 45=444.4444....≈444.44
Answer: x=444.44
To check
45% of 444.44=0.45 * 444.44≈200

Given:
Side length of larger square = 10 in
Side length of smaller square = 5 in
To find:
The probability that this point is in the shaded area.
Solution:
Area of square formula = side²
Area of larger square = 10²
= 100 in²
Area of smaller square = 5²
= 25 in²
Shaded area = Area of larger square - Area of smaller square
= 100 in² - 25 in²
Shaded area = 75 in²
= 0.75
The probability of point in shaded area is 0.75.
Answer:
0.75

Look at this for a second:
Volume = (length) x (width) x (height)
Divide each side of this equation by (length) x (width), and you have
Height = (Volume) / (length x width)
You have all the numbers on the right side, so you can easily find the height.
set up your equation
Length x Width x Height = Volume
plug in the known factors and simplify L x W x H. Divided the numerical value on both sides. you are left with H

squares are the number times itself so
x time x and (x+1) times (x+1)
so therefor the difference is 31
obviously (x+1) times (x+1) is bigger than x times x so
x times x=(x+1) times (x+1)-31
so you multiply to findn the answer
x times x=x^2
pemdas so multiply
(x+1)(x+1)
use distributive property which si a(b+c)=ab+ac so
(x+1)(x+1)=(x+1)(x)+(x+1)(1)
distribute again
(x+1)(x)=x^2+1x
(x+1)(1)=1x+1
(x+1)(x+1)=x^2+1x+1x+1=x^2+2x+1
so we have
x^2=x^2+2x+1-31
add like terms
x^2=x^2+2x-30
subtract x^2 from both sides
x^2-x^2=x^2-x^2+2x-30
0=0+2x-30
0=2x-30
add 30 to both sides
30=2x
divide both sides by 2
15=x

x+1 is second number
15+1=16
the numbers are 15 and 16
their squares are 225 and 256
the numbers are 15 and 16
