a. a survey of 300 students showed that 225 of them drove to school.
b. a survey of 220 students showed that 154 of them drove to school.
c. a survey of 100 students showed that 65 of them drove to school.
d. a survey of 440 students showed that 330 of them drove to school.

in math class 4 students complete individual surveys to determine the percentage of high school students that drive to school. which two surveys show proportional results

it A and D    :)

Step-by-step explanation:The survey results from A and D are proportional. Both show that 75% of students drive to school.

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

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!
