Answer:
68
Step-by-step explanation:
I just know I was in class with my teacher
1. You should draw a diagram with the information given in the problem. As you can see in the figure attached, there are two triangles, so, you can calculate the height of the lamp post as below:
h1/b1=h2/b2
h1 is the height asked.
b1=360 cm+ 90 cm
b1=450 cm
h2=160 cm
b2=90 cm
2. When you substitute these values into h1/b1=h2/b2, you obtain:
h1/450 cm=160 cm/90 cm
3. Now, you must clear the height "h1". Then, you have:
h1=(160 cm)(450 cm)/90 cm
h1=72000 cm²/90 cm
h1=800 cm

The answer is: 800 cm
Answer:
A. Part to whole
You are comparing the vanilla ice cream (part of the whole) to the total number of ice cream cups (the whole), so therefore you have a part to whole comparison.
I hope I could help :)
Answer:
x = 3 ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Step-by-step explanation:
Given
=
=
( cross- multiply )
5x = 2(5 + x) ← distribute
5x = 10 + 2x ( subtract 2x from both sides )
3x = 10 ( divide both sides by 3 )
x =
= 3 ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
