Which best explains why (-4) = 4
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.
How many times greater is the value of the 2 in 270,413 than the value of the 2 in 419,427
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.
Which expression has a value equal to 28 divided by 4
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.
how many 1/16 - pound servings are there in a bag of almonds that weighs 3/4 pound
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.
Last week crista spent 2 3/4 hours playing piano. this week she spent 3 2/4 hours playing piano. how much more time did she play piano this week?
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.
