Standing on the roof of her apartment building, the top of Carla’s head is 15 yards above the ground. She spots a curb 20 yards from the base of the building. What is the height of the flagpole?

9 yards.

Step-by-step explanation:

We would solve for this using proportion

Top of Carla's head / Distance of the curb from the building = Height of the flag/ distance of the flag to the building

Top of Carla's head = 15 yards

Distance of the curb from the building = 20 yards

Height of the flag pole = unknown = X

Distance of the flag from the building = 12 yards

Hence,

15/ 20 = X/12

Cross Multiply

20 × X = 15 × 12

20X = 180

X = 180/20

X = 9

Therefore, the height of the flag pole = 9yards

i dont know

step-by-step explanation:

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!
