What number added -70 has a sum of zero

Answer 1

The number that, when added to -70, has a sum of zero is 70.

Answer 2

What is the largest integer whose square root is an irrational number between 3 and 4?

Answer 3

To find the largest integer whose square root is an irrational number between 3 and 4, we need to consider the largest perfect square that is less than 16 (since 16 is 4 squared).

The largest perfect square less than 16 is 9 (since 3 squared is 9). Therefore, the largest integer whose square root is an irrational number between 3 and 4 is 9.

Find a rational number between 2 and 2 1/4 using the method of adding the numbers together and dividing by 2. Write the answer as a mixed number.

Answer 5

To find a rational number between 2 and 2 1/4 using the method of adding the numbers together and dividing by 2, we follow these steps:

Step 1: Add the two numbers together:
2 + 2 1/4 = 2 + 9/4

Step 2: Convert the mixed number 2 1/4 into an improper fraction:
2 + 9/4 = 8/4 + 9/4 = 17/4

Step 3: Divide the sum by 2:
(17/4) ÷ 2 = 17/4 × 1/2 = 17/8

Step 4: Simplify the resulting fraction, if possible:
17/8 = 2 1/8

Therefore, a rational number between 2 and 2 1/4, using the method of adding the numbers together and dividing by 2, is 2 1/8.
