As an AI language model, I cannot say that (-4) equals 4 because that is not mathematically correct. (-4) is a negative number and 4 is a positive number. They are not equal to each other unless there is a specific mathematical operation or context involved. Please provide more information on the problem to explain the possible reasoning behind this statement.

The value of each digit in a number is determined by its place value.

In the number 270,413:

- The value of the first 2 (from the right) is 2 units or 2
- The value of the second 2 (from the left) is 2 hundreds or 200

In the number 419,427:

- The value of the first 2 (from the right) is 2 ten-thousands or 20,000
- The value of the second 2 (from the left) is 2 thousands or 2,000

To find out how many times greater the value of the 2 in 270,413 is than the value of the 2 in 419,427, we need to divide the value of the 2 in 270,413 by the value of the 2 in 419,427:

200 ÷ 2,000 = 0.1

Therefore, the value of the 2 in 270,413 is 0.1 times (or 1/10th) the value of the 2 in 419,427.

Alternatively, we can say that the value of the 2 in 419,427 is 10 times greater than the value of the 2 in 270,413.

The expression that has a value equal to 28 divided by 4 is:

28/4

This can also be simplified to:

7

Therefore, the expression that has the same value as 28 divided by 4 is 7.

To find the number of 1/16-pound servings in a 3/4-pound bag of almonds, we need to divide the weight of the bag by the weight of one serving:

3/4 ÷ 1/16

To divide by a fraction, we multiply by its reciprocal (invert and multiply):

3/4 ÷ 1/16 = 3/4 × 16/1 = 48/4

Now we can simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 4:

48/4 = 12

Therefore, there are 12 servings of 1/16 pound in a bag of almonds that weighs 3/4 pound.

To find out how much more time Crista played piano this week, we need to subtract the time she spent playing piano this week from the time she spent playing piano last week:

3 2/4 hours = 3 + 2/4 hours = 3 + 1/2 hours = 3.5 hours

2 3/4 hours = 2 + 3/4 hours = 2.75 hours

3.5 hours - 2.75 hours = 0.75 hours

Therefore, Crista played piano for an additional 0.75 hours, or 45 minutes (since there are 60 minutes in an hour), this week compared to last week.

To find the total hours Crista spent playing piano in both weeks, we need to add the time she spent playing piano last week and the time she spent playing piano this week:

2 3/4 hours = 2 + 3/4 hours = 2.75 hours

3 2/4 hours = 3 + 2/4 hours = 3 + 1/2 hours = 3.5 hours

Total hours = 2.75 hours + 3.5 hours = 6.25 hours

Therefore, Crista spent a total of 6.25 hours playing piano in both weeks.

I apologize, as an AI language model I'm unable to see any drop-down menu. Please provide me with the decimals you want me to help you sort from greatest to least.
Answered by Bot
I'm sorry, as an AI language model I cannot see or interact with a dropdown menu. But, I can help you to order the given decimals from greatest to least:

8.31, 8.3, 8.296, 8.06

Therefore, the order from greatest to least is 8.31, 8.3, 8.296, 8.06.

To divide two fractions, we multiply the first fraction by the reciprocal of the second fraction. Therefore,

4/5 ÷ 3/4 = 4/5 × 4/3

We can simplify 4/5 and 4/3 by dividing both numerator and denominator by their greatest common factor, which is 1:

4/5 = 4 ÷ 1 / 5 ÷ 1 = 4/5

4/3 = 4 ÷ 1 / 3 ÷ 1 = 4/3

Substituting these simplified fractions back in the equation:

4/5 ÷ 3/4= 4/5 × 4/3 = 16/15

Therefore, the result of 4/5 ÷ 3/4 is equal to 16/15.

It is impossible to determine the number of rays in the figure without a visual representation or a more detailed description of the figure. Please provide more information or a visual representation of the figure for me to accurately count the number of rays in the figure.

A triangle by definition has only three sides. Therefore, a triangle cannot have parallel sides because it only has three non-collinear points, which means that any two sides must intersect at one point (the third vertex) and cannot be parallel.
