1. What is 125 divided by 10 with a remainder?

5

12.5

12 with a remainder of 5

125

12 with a remainder of 10

When we divide 125 by 10, we get 12 as the quotient and 5 as the remainder. This means that 10 can go into 125 twelve times, with a remaining 5.

Explanation

When we divide 125 by 10, we get 12 as the quotient and 5 as the remainder. This means that 10 can go into 125 twelve times, with a remaining 5.

2. What is 1/2+.25? Give a single number answer with no periods in a fraction form.

To find the sum of 1/2 and 0.25, we need to convert 0.25 to a fraction form with the same denominator as 1/2. Since 1/2 is equivalent to 2/4, we can rewrite 0.25 as 0.25/1 and multiply both the numerator and denominator by 4. This gives us 1/4. Now, we can add 2/4 and 1/4 together, resulting in 3/4. Therefore, the answer is 3/4.

3. An obtuse angle is an angle that is...

Less than 90 degrees.

90 degrees.

More than 90 degrees.

180 degrees.

None of the above.

An obtuse angle is defined as an angle that is greater than 90 degrees but less than 180 degrees. It is not 90 degrees because that is a right angle. An obtuse angle is larger than 90 degrees, but it is not 180 degrees because that is a straight angle. Therefore, the correct answer is that an obtuse angle is more than 90 degrees.

6. List all the whole number factors of 24. Separate with a comma and no period or comma at the end. List the pairs next to each other with the lower factor first, proceeding with 1, 24, 2, etc.

The whole number factors of 24 are numbers that divide evenly into 24 without leaving a remainder. The pairs of factors are listed next to each other, with the lower factor first. Starting with 1, which is a factor of all numbers, we find that 24 divided by 1 equals 24. Moving on to 2, we find that 24 divided by 2 equals 12. Continuing this pattern, we find the factors 3, 4, 6, 8, and 12. Therefore, the correct answer is 1, 24, 2, 12, 3, 8, 4, 6.
