Answer:
72.
Step-by-step explanation:
Number of strings with exactly 2 1's
= 9C2
= 9*8/2*1
= 36.
Same for 2 0s
= 36.
Truck is 30% less than bus
40 divided by 1.3 = 30.77
Car is 75% less than truck
30.77 divided by 1.75. = 17.58 feet
Answer:
(Since 3.14 seems more reliable, I'll use that for all four instead)
A: 17.6 ft
B: 81.6 mm
C: 9 cm

This question has this set of answer choices:
a) when the plane cuts three faces of the cube, separating one corner from the others
b) when the plane passes through a pair of vertices that do not share a common face
c) when the plane is perpendicular to the base and intersects two adjacent vertical faces
d) when the plane makes an acute angle to the base and intersects three vertical faces
e) not enough information to answer the question
The right answer is the first choice: a) when the plane cuts three faces of the cube, separating one corner from the others
You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.
