Suppose you're on a game show, and you're given the choice of three doors: behind one door is a sports car; behind all of the others is bicycles. you pick a door, say no. 1, and the host, who knows what's behind the doors, opens another door, say no. 2, revealing a bicycle. he then says to you, "do you want to pick door no. 3? " is it to your advantage to switch your choice?

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other

step-by-step explanation:

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
