Jennifer had a 7/8- foot board. She cut off a 1/4 foot piece that was for a project. In feet, how much of the board was left

Answers

Answer 1
Answer:

Answer: There was 5/8 of a foot of board left.

Step-by-step explanation:

Step 1. We need to subtract 1/4 from 7/8. To do this make it where both fractions have the same denominator.

Step 2. The easiest way to do this is to multiply 1/4 by 2.

1/4*2/2=2/8.

Step 3. Now all you got to do is subtract 2/8 from 7/8.

7/8-2/8= 5/8.

Supposed you list the factors of a perfect square why is one factor a square root and not the other factors ?

Answers

No factor of a perfect square is a square root, (unless it's the square root of a perfect-
square number, and then it can be replaced by the number that's the square root of
what's inside the radical).

The  factors of a perfect square are just whole numbers.

256 is a perfect square.

Its factors are 1, 2, 4, 8, 16, 32, 64, 128, and 256. 

My teacher just gave me the sequence 7, 13, 19. He told us that the next answer is not 25. Please help.

Answers

7, 13 , 19.

An arithmetic sequence is one that has a common difference.

13 - 7 = 6.
19 - 13 = 6.

So the next in the sequence is 19 + 6 = 25.

The next in the sequence is 25. 

It is not affected by what any one says. 

Which of the following expressions is equivalent to 6 - (-5)?a. 6 - 5
b.6 + 5
c.-6 + 5
d.-6 + (-5)

Answers
