To decrease an amount 37% multiply by

if x is the amount =100%

then to decrease the amount by 37% =(100-37)% = 63% of x =x*63/100 =x*0.63

multiply the amount by 0.63

Step-by-step explanation:

0.63

Step-by-step explanation:

if x is the amount=100% then to decrease by 37% multiply by 0.63

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.
