I've been waiting for someone to ask this question. It's one of my favorite questions to answer.
percent means out of 100 so 1% = 1/100 and 40%=40/100 or 1/25
so for percent of a number, 'of' means multiply so 40% of 500= 40/100 times 500 or 20000/100 or 200
if you multiply a fraction by its recipricol (the number fliped upside down) the you will get 1 so if you multiply 1/2 by 2/1 then you will get 1
thus
percent is out of 100 so 1%=1/100 25%=25/100
if you represent 45 out of something as 45/x then you multiply it by the reciprocal of the fraction that is supposed to be equal (1/2 =2/4) then you will get 1
so 45/x times reciprocal of 100/25 then you will get 1/1 or 4500/25x
so you divide to find x and get 180
so 45 is 25% of 180
The following is extra
as stated above 'of' can be taken as multiply so
45 is 25% of 180 can be rewriten as
45=25/100 times 180
but we don't know that 180 is the answer so we replace it with x then solve for x
Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
So whatever games he plays you keep adding $2 and add $1 for the amount of shoes he buys
Answer:
it would be C
Step-by-step explanation:
A trapiziod equals 360 degrees in total, so 110+110+70 is 290.
the total degrees 360-290 would give you 70 degrees, so C is correct.
