Sam places a mirror on the ground, 5 m from the base of a tree. He then walks backwards until he can see the top of the tree in the mirror. He is now standing 0.75 m from the mirror. Sam’s eye level is 1.75 m high. What is the height of the tree?

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
