The area is found by base x height

To find the missing height in the first one you divide 147 by 15 3/4 and get 9 1/3. 
To find the missing base in the second one you divide 140 5/8 by 11 1/4 and get 12 1/2.
To find the missing height in the third one you divide 151 3/16 by 10 1/4 and get 14 3/4.

A ___________ is always a number where the units from two different quantities are combined to describe the result.
LekaFEV [45]

Answer:

Step-by-step explanation:All other quantities of physical objects can be expressed as combinations of these fundamental quantities. For example, density is volume per mass. It can be expressed as a combination of the fundamental quantities mass (M) and length (L), M/(L × L × L) = M/L3. Similarly, area is a function of length, L × L = L2.

What 2 numbers whose sum is 105.7 the numbers are 19, 85.2, 533, 571, 88.2, 525, 20, 17.5, 400, 261, 20.5 ,125, 7, 23, 901, 30

To make it quickly we can consider only those numbers which will give us a decimal of xxx.7. There are only a few numbers like this: 85.2, 88.2, 20.5.
 
I tried adding 85.2 to 17.5 and it gave me 102.5 - it was close but not close enough :)

So I picked 85.2 + 20.5 = 105.7 and voila :)
