Which number from the set { 1.324, 1, - 8/21 } is classified as an integer? (1 point)
The number 1 is classified as an integer because integers are whole numbers, without any fractional or decimal parts.
What is the opposite and absolute value of -214
The opposite of -214 is 214. The absolute value of -214 is also 214.
does | - 40| ≠ |40|
No, it is not correct to say that | -40| ≠ |40|. In fact, the absolute value of -40 and the absolute value of 40 are both equal to 40. The absolute value function removes the negative sign from a number, so regardless of whether a number is positive or negative, its absolute value will always be positive.
does | - 40| > |40|
No, it is not correct to say that | -40| > |40|. In fact, the absolute value of -40 and the absolute value of 40 are both equal to 40. The absolute value function removes the negative sign from a number, so regardless of whether a number is positive or negative, its absolute value will always be positive. Therefore, | -40| and |40| are equal.
What does 22+-20 equal
22 + (-20) equals 2.
Represent -5x-4 with a model
A possible way to represent -5x - 4 with a model is by using a number line.
First, draw a horizontal line and mark it with integers. Place a point at 0 to represent the origin.
Then, starting from 0, move 5 units to the left to represent -5x. This indicates that 5x is subtracted.
Next, starting from the point representing -5x, move 4 units further to the left to represent -4. This indicates that 4 is subtracted.
The final point on the number line represents -5x - 4.
-9x(-18)
To represent -9x(-18) with a model, you can use a rectangular array.
Begin by drawing a rectangle and divide it into 9 rows and 18 columns. Each cell within the rectangle represents a product of -9 and -18.
To calculate each product, multiply -9 by -18. The result of this multiplication is 162.
Once you calculate all the products for each cell within the rectangle, you can sum them to find the overall result of -9x(-18). In this case, the sum of all the products will be 162 times the number of cells in the rectangle (9 rows * 18 columns).
So, -9x(-18) equals 162 * (9 * 18).
-30 divided by -6
To divide -30 by -6, you can simply perform the division operation.
Dividing -30 by -6:
-30 ÷ -6 = 5
Therefore, -30 divided by -6 equals 5.
-245 divided by 25
To divide -245 by 25, you can perform the division operation.
Dividing -245 by 25:
-245 ÷ 25 = -9.8
Therefore, -245 divided by 25 equals -9.8.
-108-(-18)(-18)(-18)(-18)(-18)(-18)=0
Describe the relationship between whole numbers, integers, and rational numbers
Whole numbers, integers, and rational numbers are all different subsets of the number system.
Whole numbers are the set of non-negative integers (0, 1, 2, 3, ...), including zero. They do not include any fractions, decimals, or negative numbers.
Integers are the set of whole numbers (including zero) and their opposite (negative numbers). Integers include all negative numbers (-1, -2, -3, ...) as well as zero and positive numbers (0, 1, 2, 3, ...).
Rational numbers are numbers that can be expressed as a fraction, where both the numerator and denominator are integers (whole numbers). Rational numbers include integers, as well as fractions and decimals that can be converted into a fraction. For example, 1/2, 3/4, -2/5, -0.75 are all rational numbers.
In summary, whole numbers are a subset of integers, and integers are a subset of rational numbers. Rational numbers include both whole numbers (integers) and their fractions or decimals.
Actually, the result of the expression -108 - (-18)(-18)(-18)(-18)(-18)(-18) is not zero.
To calculate it correctly, we need to perform the multiplication first:
(-18)(-18)(-18)(-18)(-18)(-18) = -19683
Then, substitute this value back into the original expression:
-108 - (-19683) = -108 + 19683 = 19575
Therefore, -108 - (-18)(-18)(-18)(-18)(-18)(-18) equals 19575, not zero.
