Ascale drawing of a school bus has a scale of 1/2 inch to 5 feet. if the length of the school bus in 4 1/2 inches on the scale drawing, what is the actual length of the bus

Let 4_1/2 = 9/2 inches as an improper fraction.

(9/2) ÷ (1/2)

(9/2) (2/1)

9 x 5 = 45

The bus is 45 feet in length.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

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!
