Question

Marissa is standing next to an 18 door tall flagpole that is casting a 12 foot long shadow. If Marissa's shadow is 3.5 feet long, how tall is Marissa

Answer 1

I did this in my head. the answer would be, 5.1428571429.

Answer 2

Answer:

5'3

Step-by-step explanation:

This question will look like this: 18/12  x/3.5. Remember about height/shadow.

You will need to cross multiply 18 and 3.5 and keep 12, x as 12x.

Now it will look like this: 12x=63. Divide that 63 with 12 and you will get 5.25.

Since there is a 5 next to that 2 you add 1 because 5 or higher add one and 5 or lower don't add anything.

You got rid of that 5 and added 1 to the 2, you will have 5'3

Hoped it helped!
