Answer:
Total number of edges for resulting solid = 12
Step-by-step explanation:
A wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points that are 1 inch from each corner.
We have to find the number of edges in the resulting solid after we cut the edges as told above.
There are two faces along the height which will become sharpened after we take out the cuts.
So the resulting shape would be like that of a cylinder with its both ends pointed.
So total number of edges = 4 + 4 + 4 = 12
Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes
When Sawyer went to sleep it was -2.
Overnight the temperature dropped -15 degrees more.
-2 + -15 = -17
When Sawyer woke up, the temperature was -17 degrees.
