The public library surveyed 220 people about their favorite type of movie. If 25% of the people chose documentaries, how many people chose documentaries?

55 people.

Step-by-step explanation:

Multiply 220 by the percentage in decimal form. To make any percentage to a decimal, simply move the decimal 2 spaces to the left. Now instead of 25, you have 0.25. Multiply this by 220 to get 55. Hope the Helps!

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
