-9 × -10
When we multiply two negative numbers, the result is a positive number. Therefore:
-9 x -10 = 90
8 ÷ -1
When we divide a number by -1, the result is the opposite (negation) of that number. Therefore:
8 ÷ -1 = -8
Select all three true statements
-4.5 = [ -4.5]
86= [ 86 ]
[ -10 2/3] = 10 2/ 3
-[1/3] = 1/3
[-57] = 57
-4.5 = [ -4.5] is a true statement because the brackets indicate the greatest integer that is less than or equal to the number, so the greatest integer less than or equal to -4.5 is -5.
86 = [ 86 ] is a true statement because the greatest integer less than or equal to 86 is 86 itself.
[-57] = 57 is a true statement because the brackets indicate the greatest integer that is less than or equal to the number, so the greatest integer less than or equal to -57 is -57, but the brackets indicate the absolute value of the number, which is 57.
Therefore, the three true statements are:
-4.5 = [ -4.5]
86 = [ 86 ]
[-57] = 57
Order the numbers from closest to zero to farthest from zero
4.38, [4.5], [-4.6] -[4.9]
The order from closest to zero to farthest from zero would be:
[4.5], 4.38, -[4.6], -[4.9]
The numbers in the brackets represent the greatest integer less than or equal to the number. Therefore, [4.5] is 4 and -[4.6] is -5.
So, the closest numbers to zero are 4 and 4.38, followed by -4.6, and then -4.9 is the farthest from zero.
Your answer is wrong
I apologize for the mistake in my previous response. The correct order from closest to zero to farthest from zero is:
[4.5], 4.38, -[4.6], -[4.9]
The numbers in the brackets represent the greatest integer less than or equal to the number. Therefore, [4.5] is 4 and -[4.6] is -5.
So, the closest numbers to zero are 4 and 4.38, followed by -4.6, and then -4.9 is the farthest from zero.
I apologize again for my mistake and thank you for bringing it to my attention.
Can you order the numbers in a different way
Yes, certainly! Another way to order the numbers from closest to zero to farthest from zero is:
4.38, [4.5], -[4.6], -[4.9]
Here we are ordering the numbers in ascending order, so 4.38 is the closest number to zero, followed by [4.5] which is 4, then -[4.6] which is -5, and finally -[4.9] which is -5.
Which of the following expressions is equivalent to
[ 2/7] 3
Since the brackets represent the greatest integer that is less than or equal to the number, we can first find the greatest integer that is less than or equal to 2/7, which is 0. Therefore, we have:
[ 2/7] 3 = 0 x 3 = 0
So, the expression that is equivalent to [ 2/7] 3 is simply 0.
Can you do answer in a another way
Another way to think about it is:
[2/7] is the greatest integer that is less than or equal to 2/7, which is 0.
So, [2/7] 3 = 0 x 3 = 0.
Therefore, [2/7] 3 is equivalent to 0.
Is ( 2/7) equivalent to
2 x 2/7
3× 2/7
2/7 × 2/7
2/7 × 2/7 × 2/7
(2/7) is not equivalent to any of the expressions given because all the expressions simplify to different values than 2/7. Let's simplify each of the expressions to see why:
2 x 2/7 = 4/7
3 x 2/7 = 6/7
2/7 x 2/7 = 4/49
2/7 x 2/7 x 2/7 = 8/343
Therefore, none of the expressions are equivalent to (2/7).
So what is your answer
(2/7) is not equivalent to any of the given expressions.
5 ^ 3 is bigger than 3 ^ 5
True or false
False.
To compare the values of 5^3 and 3^5, we can calculate their decimal approximations using a calculator:
5^3 = 125
3^5 = 243
Here, we can see that 3^5 is greater than 5^3. Therefore, the statement "5^3 is bigger than 3^5" is false.
Compare the integers-2 and -10 on a horizontal number line which integers is furthest to the right
-2
-10
On a horizontal number line, increasing values are associated with a move towards the right. In this case, -2 is closer to 0 on the number line compared to -10.
So, if we plot -2 and -10 on a horizontal number line, -2 will be to the right of -10 as it's closer to 0 on the number line. Therefore, -2 is the integer that is furthest to the right.
Order the rational numbers from least to greatest
-10, 2, -0.5, 5/16
To order the given rational numbers from least to greatest, let's convert them all to fractions with a common denominator:
-10 = -10/1
2 = 2/1
-0.5 = -1/2
5/16 = 5/16
The common denominator for these fractions is 16. So, we have:
-10/1 = -160/16
2/1 = 32/16
-1/2 = -8/16
5/16 = 5/16
Now, we can arrange these fractions from least to greatest:
-160/16 < -8/16 < 5/16 < 32/16
Simplifying these fractions, we get:
-10 < -0.5 < 5/16 < 2
Therefore, the rational numbers in order from least to greatest are:
-10, -0.5, 5/16, 2.
