Step-by-step explanation:
To Express fraction as a percentage, convert to a decimal then multiply by 100
= 31/50 = punch 31 ÷ 50 in a calculator, it gives 0.62
To Express in percentage
= 0.62 x 100
=62%

Answer:
2x^2+7
Step-by-step explanation:
Let x=5
2x^2+7
2 ( 5)^2 +7 = 2*25 +7 = 50+7 = 57
(x^3-5)/3
(5^3 -5)/3 = (125-5)/3 = 120/3 = 40
(10x -2)/ (x-3)
(10*5-2)/(5-3) = (50-2)/(2) = 48/2 = 24
Width = w
length = 11w
Pythagoras theorem
a^2 + b^2 = c^2
Let's say the width is a, the length is b, and the distance between corners (call it d) is c
w^2 + 11w^2 = d^2
Collect like terms,
12w^2 = d^2
Simply
12w = d
Answer:
75%
Step-by-Step Explanation:
There are two ways to go about this.
1) We can simply put it as a fraction = 60/80.
Then since a fraction sign also means division, we divide 60 by 80 = 0.75
Then to change a decimal into a percentage, we multiply by 100% = 75%
So our answer is 75%
2) We can simply it after it is put into a fraction = 60/80 = 3/4
It should be common knowledge that 3/4 is 75% depending on what grade you are in.
But there you have it, whichever way you prefer, the answer is always 75%.
Answer:
The ratio of boys to girls to 5:7
Let the number of boys be 5x
Let the number of girls be 7x
5x = 30
x = 6
Now just plug in 6 for the x in 7x
and number of girls 7 x 6 = 42
