We have,
To round 871 to the nearest ten, we look at the ones digit, which is 1.
If the ones digit is 5 or greater, we round up to the next ten.
If the ones digit is less than 5, we round down to the previous ten.
In this case, the ones digit is 1, which is less than 5.
Therefore, we round down.
Rounding 871 to the nearest ten gives us 870.
Thus,
Rounding 871 to the nearest ten gives us 870.

Is 1.47 irrational or rational
Which expression is equivalent to 9x^5+3x(4x^4-3x^2)^2
Answer:
[tex]48x^9-72x^7+36x^5[/tex]
Step-by-step explanation:
The initial expression is:
[tex]9x^5+3x(4x^4-3x^2)^2[/tex]
First expand the squared part (inside the parenthesis):
[tex]9x^5+3x(4x^4-3x^2)(4x^4-3x^2)\\9x^5+3x(16x^8-24x^6+9x^4)\\[/tex]
Then, multiply the terms inside the parenthesis by 3x applying the distributive property:
[tex]9x^5+3x(16x^8-24x^6+9x^4)\\9x^5+48x^9-72x^7+27x^5[/tex]
Finally add terms with the same exponent
[tex]48x^9-72x^7+36x^5[/tex]
Answer:
D. 48x^9-72x^7+36x^5

The table shows the number of balls, by sport, in the gym.
A. The ratio of soccer balls to all balls is 4:25
B. For every 10 balls in the gym, 3 are basketballs
C. None of the above
The ratio of soccer balls to all balls is 4:25.
Given that;
The table shows the number of balls, by sport, in the gym.
Now, We have;
Number of soccer balls = 8
And, Total number of balls = 50
Hence, The ratio of soccer balls to all balls is,
⇒ 8 : 50
⇒ 4 : 25
Thus, We get;
The ratio of soccer balls to all balls is 4:25.

Find the value of x and AB if B is between A and C, AB = 2x, AC = 6x - 5 , BC = 7
The problem deals with the segment addition postulate. By setting up and solving the relevant equation (2x + 7 = 6x - 5), we find that x = 3. Therefore, the length of AB = 6.
Explanation:The subject of this question is segment addition postulate in mathematics. Given that B is between A and C, it implies that AB + BC = AC. From the problem, it's given that AB = 2x, AC = 6x - 5 and BC = 7. Setting up the equation would yield 2x + 7 = 6x - 5. Solving this equation gives us x = 3. Therefore, by substituting x=3 in AB = 2x we find that AB = 6.

A hole was dug 2 3/8 feet deep for a fence post. The fence post is 6 feet long. How far above the ground will the fence post be when it is placed in the hole? Enter your answer as a mixed number, in simplified form, in the box.
PLEASE ANSWER ASAP
[tex]\text{Answer: The fence post will be }3\frac{5}{8}\ feet\text{ far above the ground when it is placed in the hole.}[/tex]
Explanation:
Since we have given that
Length of hole dug for a fence post is given by
[tex]2\frac{3}{8}\ feet=\frac{19}{8}\ feet[/tex]
Length of the fence post = 6 feet
we need to find the length of the fence post above the ground is seen when it is placed in the hole.
So, Length of the fence post above the ground is given by
[tex]6-\frac{19}{8}\\\\=\frac{48-19}{8}\\\\=\frac{29}{8}\\\\=3\frac{5}{8}\ feet[/tex]
[tex]\text{Hence, the fence post will be }3\frac{5}{8}\ feet\text{ far above the ground when it is placed in the hole.}[/tex]

Find the measure of angle KLM.
This is an EXPLAIN YOUR THOUGHTS question which means you need to:
1) include the properties, theorems, etc. that you used to set up an equation.
2) Show the euqation you used to solve for x and thus solve for the angle measure of KLM
The measure of angle KLM is 64⁰
What are supplementary angles?Supplementary angles are two angles whose measures add up to 180⁰ In other words, when placed adjacent to each other, they form a straight line.
From the figure
Given
<J = (6x+4)⁰
<K = (8x + 18)⁰
<KLN = 180 -(20x +4) (supplementary angles)
In Triangle KLN
<J + <K + <L = 180⁰(sum of angles in triangle)
Substitute
(6x + 4) + (8x + 18) = (20x + 4)(sum of 2 int.<s is equal to exterior<)
Simplifying
6x + 8x - 20x = 4 - 4 - 18
14x -20x = -18
-6x = -18
x = -18/-6
= 3
Substitute into (20x + 4) to find the measure of angle KLM
20x +4 = 20(3) + 4
= 60 + 4
= 64⁰
The measure of angle KLM is 64⁰

Subtract -6 4 -6 0 6 4 - -5 5 -4 -1 6 -4
Answer:
The result of the subtraction is [tex]\(57\).[/tex]
Explanation:
To subtract the numbers given, we need to add all the positive numbers and then subtract the sum of the negative numbers.
Positive numbers: [tex]\(6 + 4 + 6 + 4 + 5 + 5 + 6 = 36\)[/tex]
Negative numbers: [tex]\(-6 - 6 - 4 - 1 - 4 = -21\)[/tex]
Subtracting the sum of the negative numbers from the sum of the positive numbers:
[tex]\(36 - (-21) = 36 + 21 = 57\)[/tex]
So, the result of the subtraction is [tex]\(57\).[/tex]
