Answer: 39
Step-by-step explanation:
180-(39+102)
180-141
39
Do you have 1 7/8 divided by one half. With dividing you multiply by the reciprocal of 1/2 which is 2/1. Before you do that change 1 7/8 into a mixed number which is 15/8. 15 x 2= 30, 8 x 1=8. New fraction is 30/8. Now as a mixed number it is 3 6/8 which simplifies to 3 3/4. So your answer is D
Here, we may use Geometric Progression
The sequence follows as:
27, 18,12,...
The first term (a)= 27
27/18 = 18/12
common ratio = 1.5
Let fourth term be x
Therefore , 12/x = 1.5
=> x= 12/1.5 = 8
Vol. of a rect. prism is V = L*W*H.
Here, that vol. is V = (2.5 ft)(1.5 ft)(4 ft) = 15 cubic feet (answer)
Note: volume (not valume).
