Alan made a small four sided table for his office .Two sides of the table are 27 inches long and 36 inches long .If the diagonal
Tcecarenko [31]

Answer:

does NOT have right angles at the corners

Step-by-step explanation:

we are given that the sides of a table are 27" and 36" long.

If we assume the table to be rectangular, then by Pythagorean formula, we can find the diagonal and compare it to the 40" that we are given.

(refer to attached)

diagonal² = 27² + 36²

diagonal² = 27² + 36²

diagonal² = 2025

diagonal = √2025

diagonal = 45 inches

because the diagonal that we found is not the same as the 40" that was given, we can conclude that the table is not a rectangle (i.e does not have right angles at the corners)

Rafi had a board that was 15 1/2 feet long. He cut three pieces off the board that are each 3 7/8 feet long. How much of the boa
sattari [20]

Answer:

Step-by-step explanation:

To answer this question, first we need to figure out how much of the board Rafi cut off.

To do this, we need to multiply the length of each piece by the number of pieces he cut off.

3 7/8 = 3.875

3.875 * 3 = 11.625

Now, because we knew Rafi cut off 11.625 feet off of the board, we just need to subtract this length from the length of the entire board to find the remaining length.

15 1/2 = 15.5

15.5 - 11.625 = 3.875

There is 3.875 feet or 3 7/8 of the board left.
