Answer:
Step-by-step explanation:

90. you can just do 5x12 which is 60. 60x3 is 180 then 180 divided by 2 because a triangular prism is just half of a cube
Answer:
AB
Step-by-step explanation:
Given:
BC = BD
DE is ⊥ to AC.
GB is ⊥ CD.
we need to find the median from the given figure.
Solution:
By Definition of Median which states that;
" a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.."
From the above figure we can see that;
Segment AB bisects the opposite side CD.
Also BC = BD (given)
Hence segment AB is a median.
Amount=number of hotdogs per package times number of packages
amount=8 times P
amount=8P
amount must be equal to or greater than 78 since each guest wants 1 at least
amount<u>></u>78
8P<u>></u>78
(if you wanted to solve, the answer is at least 10 packages)

Answer:
57,001 cm², or 5.7 square meters
Step-by-step explanation:
The surface area of a cylinder is given by the formula ...
A = 2πr(r +h)
A = 2π(14 cm)(14 cm +40 cm) = 1512π cm²
Then 12 cylinders will have an area of ...
12 × 1512π cm² = 18,144π cm² ≈ 57,001 cm²
Rui Feng wants to paint a total surface area of 57,001 cm², about 5.7 square meters.
