Use a calculator to find that
7.095*2.55 = 18.09225
Then round to the nearest tenth to get 18.1
Why the nearest tenth? Because we want the answer to have 3 sig figs. This is the smallest number of sig figs between the two original numbers (7.095 and 2.55).
Answer: Choice D) 18.1
The board is 12x larger in length than the nails. (Since the width of the board and nails are unknown, I am assuming you mean the length, not area difference)
The volume of the rectangular solid is: 11,960 units³.
<h3>How to Find the Volume of a Rectangular Solid?</h3>
The formula to find the volume of a rectangular solid is: (length)(width)(height).
Given the dimensions as:
- Length = 20 units
- Width = 23 units
- Height = 26 units
Volume = (20)(23)(26)
Volume of the rectangular solid = 11,960 units³.

Answer:
0.1569 = 15.69%
Step-by-step explanation:
If eight calls were placed, and we need to know the probability of exactly two calls were occupied, we need to calculate a combination of 8 choose 2 (all the combinations of 2 occupied calls in the 8 total calls), and multiply by the probability of each case in the 8 calls (2 cases occupied and 6 cases not occupied):
P(8,2) = C(8,2) * p(occupied)^2 * p(not_occupied)^6
P(8,2) = (8*7/2) * (0.45)^2 * (0.55)^6
P(8,2) = 28 * 0.2025 * 0.02768 = 0.1569 = 15.69%
If you are finding the perimeter I believe you would just add up the four sides, getting 46
