Kira studied data collected on the school basketball team for 1 season she noticed that a player on the team had 13 succesful free throws out of a total of 20

Percent of Total number of successful throw = 65%

Step-by-step explanation:

Given:

Total number of successful throw = 13

Total number of throw = 20

Find:

Percent of Total number of successful throw

Computation:

Percent of Total number of successful throw = [Total number of successful throw / Total number of throw]100

Percent of Total number of successful throw = [13/20]100

Percent of Total number of successful throw = 65%

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!
