66.875 = 66 7/8 as a mixed number
There are two triangles here: ABC and ADF. These triangles are similar, and thus proportional. So, we can set up a proportion between the left side of each triangle and the base of each triangle.
AB / AD = BC / DE
4 / (4 + BD) = 5 / 9
---AD is made up of AB and DB. We know AB, but not BD, so we need to find its value to find the length of AD.
5(4 + BD) = 9 x 4
20 + 5BD = 36
5BD = 16
BD = 3.2
AD = AB + BD
AD = 4 + 3.2
AD = 7.2
Hope this helps!

Sorry, if some are wrong.
What is a ton to start off?
And how many pounds are in a ton
The fractional part would be how many pounds are in the ton
I just figured it out so I’ll answer it on this account lol.
Q1 = 32, Q2 = 45, Q3 = 52
Interquartile range = 52 - 32 = 20
Range = 68 - 21 = 47
