Write 0.31% as a decimal.

= 0.0031

Step-by-step explanation:

"Percent" means "per 100" or "over 100". To convert 0.31% to a decimal rewrite 0.31 percent in terms of per 100 or over 100.

0.31% = 0.31 over 100 or,

0.31%=

0.31 over 100 is the same as 0.31 divided by 100. Completing the division we get:

0.31 ÷ 100 = 0.0031

Therefore, we have shown that

0.31% = 0.0031

Simplified Conversion:

Remove the percent sign % and divide by 100.

0.31 ÷ 100 = 0.0031

Shortcut Conversion:

Move the decimal point 2 places to the left and remove the percent sign %

0.31% becomes 0.0031

step-by-step explanation:

1/4 = .25 / 25%

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
