Pleaseee i need helppp Michelle wanted to measure the height of her school's flagpole. She placed a mirror on the ground 45 feet from the flagpole, then walked backwards until she was able to see the top of the pole in the mirror. Her eyes were 5 feet above the ground and she was 16 feet from the mirror. What is the height of the flagpole to the nearest tenth of a foot.

14

Step-by-step explanation:

45*5 = 16*x

225/16 = 16x/16

↓↓

14 = x

idk lol

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
