13,501 rounded to the nearest ten thousand is 14,000. This is because if you look at the 3, the number next to it is 5, causing it to round up. Numbers 0-4 are rounded down, and numbers 5-9 are rounded up.
Answer:
10,000
Step-by-step explanation:
When we round a number to the nearest ten thousand we check the digit at the thousand place,
If the digit ≥ 5,
The number is rounded to next ten thousand,
If the digit < 5,
The number is rounded to previous ten thousand.
Here, the given number,
13,501,
Digit at thousand place = 3 ( < 5 )
Thus, 13,501 ≈ 10,000 ( nearest ten thousand )
What is the length of the hypotenuse of the triangle of 7ft and 4ft
To find the length of the hypotenuse in a right-angled triangle with sides measuring 7ft and 4ft, use the Pythagorean Theorem: 7² + 4²= c², which gives us the hypotenuse length of approximately 8.06 feet.
The question is asking for the length of the hypotenuse of a right-angled triangle when the lengths of the other two sides are known (7ft and 4ft).
To find the hypotenuse, we use the Pythagorean Theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). The formula is expressed as a² + b² = c².
By applying the Pythagorean Theorem:
72 + 42 = c²
49 + 16 = c²
65 = c²
c = √65 ≈ 8.06 ft
Therefore, the length of the hypotenuse is approximately 8.06 feet.

How do i divide 806 by 9 with long division, im getting 9 remainder 6
The results of a poll indicate that between 33% and 37% of the population of a town visit the library at least once a year.
What is the poll’s margin of error?
Enter your answer in the box.
±___%
Final answer:
The margin of error for the poll, given a range of 33-37%, is ±2%. This means the actual percentage of the town's population that visits the library at least once a year could reasonably be expected to fall within 2% of the poll's reported value, which is 35%.
Explanation:
The margin of error in a poll is a statistic that reflects the degree of accuracy of the poll's results. It indicates how much the actual percentage could differ from the reported percentage in either direction. In this case, the poll indicates a visitation range between 33% and 37%. To calculate the margin of error, you find the difference between the highest value and the mean or the difference between the mean and the lowest value of the range.
In this instance, (37% + 33%) / 2 = 35%, which is the mean. The margin of error is then calculated as either 37% - 35% or 35% - 33%, both resulting in a 2%. Therefore, the poll's margin of error is ±2%.

what is the solution of 3x+8/x-4 >;= 0
The division between two numbers is positive if and only if they have the same sign. So, this fraction is positive if numerator and denominator are either both positive or both negative.
For this reason, you want to study the sign of numerator and denominator separately first.
As for the numerator, you have
[tex] 3x+8 \geq 0 \iff 3x \geq -8 \iff x \geq -\dfrac{8}{3} [/tex]
Similarly, for the denominator you have
[tex] x-4 > 0 \iff x > 4 [/tex]
(note that we used strict inequality for the denominator, since it can't be zero).
So, the sign of the fraction works like this:
If [tex] x \leq -\frac{8}{3} [/tex] both numerator and denominator are negative (or, at most, the numerator is zero if [tex] x = -\frac{8}{3} [/tex]), so the ratio is greater than or equal to zero.If [tex] -\frac{8}{3} \leq x < 4 [/tex] the numerator is positive and the denominator is negative (or, at most, the numerator is zero if [tex] x = -\frac{8}{3} [/tex]), so the ratio is less than or equal to zero.If [tex] x >4 [/tex] both numerator and denominator are positive, so the ratio is greater than or equal to zero.Answer:

A car is purchased for $29500. After each year, the resale value decreases by %35. What will the resale value be after 4 years
Using the exponential decay formula, the resale value of a car initially purchased at $29,500 and depreciating at 35% per year will be approximately $5,266.08 after 4 years.
To calculate the resale value of a car after depreciation, we can use the formula for exponential decay, which is [tex]V = P (1 - r)^t[/tex], where V is the future value of the car, P is the initial purchase price, r is the rate of depreciation, and t is the time in years. In this case, P = $29,500, r = 35% or 0.35, and t = 4 years.
Following the formula, the resale value after 4 years would be:
V = $29,500 (1 - 0.35)⁴
V = $29,500 (0.65)⁴
V = $29,500 (0.17850625)
V = $5,266.08 approximately
Therefore, the resale value of the car after 4 years will be around $5,266.08.

Factor.
9x^4−64y^2
To factor 9x^4 - 64y^2, use the difference of squares formula. The factored form is (3x^2 + 8y)(3x^2 - 8y).
To factor 9x^4 - 64y^2, we can use the difference of squares formula: a^2 - b^2 = (a + b)(a - b). Applying this, we get: 9x^4 - 64y^2 = (3x^2 + 8y)(3x^2 - 8y)
Therefore, the factored form of 9x^4 - 64y^2 is (3x^2 + 8y)(3x^2 - 8y).

Answer:
The width of the room is 20 feet.
The Length of the room is [tex]46[/tex] feet.
Step-by-step explanation:
Lets take the width of the room as [tex]x[/tex] feet
Then the length of the room will be [tex]2x+6[/tex] feet

Therefore,
The width of the room is 20 feet.
The Length of the room is,
[tex]2x+6[/tex] = [tex]2*20+6[/tex] = [tex]46[/tex] feet

2. Option d) 123
3. Options 3 and 4:
Triangle Angle-Sum Theorem
Triangle Exterior Angle Theorem
4. Option c) x=37
Solution:
1. Part A
First, you can find x using the triangle angle-sum theorem: The sum of the interior angles of any triangle must be equal to 180°.
Second, you can apply the vertical angles theorem to find y: the angles opposite by the vertex must be congruent.
Then, the answer is option a) vertical angles theorem and triangle angle-sum theorem.
1. Part B.
First: Triangle angle-sum theorem
The sum of the interior angles of any triangle must be equal to 180°. The interior angles of the triangle in the figure are x°, 30°, and 70°, then:
x°+30°+70°=180°
(x+30+70)°=180°
(x+100)°=180°
x+100=180
Solving for x: Subtracting 100 both sides of the equation:
x+100-100=180-100
x=80
Second: Vertical angles theorem: The angles opposite by the vertex must be congruent:
In the figure, the angles x° and y° are opposite by the vertex, then they must be congruent:
y°=x°
y=x
and x=80, then:
y=80
Answer: Option b) x=80, y=80

Answer: Option d) 123
3.
You can apply the Triangle Angle-Sum Theorem, to find the third interior angle of the triangle. With this angle you can find the exterior <1.
You can apply the Triangle Exterior Angle Theorem to find the exterior <1.
Answer: Options 3 and 4:
Triangle Angle-Sum Theorem
Triangle Exterior Angle Theorem
4. Using the Triangle angle-sum theorem:
The sum of the interior angles of any triangle must be equal to 180°. The interior angles of the triangle in the figure are (2x-9)°, x°, and (2x+4)°, then:
(2x-9)°+x°+(2x+4)°=180°
(2x-9+x+2x+4)°=180°
Adding similar terms:
(5x-5)°=180°
5x-5=180
Solving for x: Adding 5 both sides of the equation:
5x-5+5=180+5
Adding:
5x=185
Dividing both sides of the equation by 5:
(5x)/5=185/5
x=37

Write the slope-intercept form of the equation that fits the conditions.
Perpendicular to y=-1/3x+1
Passes through (5,-2)
How do I solve this??
Answer:
y = 3x - 17
Step-by-step explanation:
Here is the point-slope form of the equation of a line.
[tex] y - y_1 = m(x - x_1) [/tex]
If you are given a slope, m, and a point on the line, (x1, y1), you just plug in the values into the equation above, and you get the equation of the line.
In your problem, you are given a point on the line, (5, -2). Now you need the slope of the line. Your line is perpendicular to the given line. The slopes of perpendicular lines are negative reciprocals. If you know the slope of a line, the slope of its perpendicular is found by flipping the fraction and changing the sign.
The given line has slope -1/3.
Flip -1/3 to get -3.
Now change the sign to get 3.
The slope of the line you need is 3. The line passes through point (5, -2).
Now we use the point-slope equation and we plug in the values we have.
[tex] y - y_1 = m(x - x_1) [/tex]
[tex] y - (-2) = 3(x - 5) [/tex]
[tex] y + 2 = 3x - 15 [/tex]
[tex] y = 3x - 17 [/tex]
What variation is f(x) = 3x

B. Indirect variation
C. Inverse variation
D. Quadric variation
E. None of the above
Direct variation
The equation is written as y=mx+b
The variation f(x) = 3x is A. Direct variation.
The function f(x) = 3x represents a type of relationship called a direct variation. In mathematics, a direct variation can be expressed in the form y = kx, where k is a constant. Here, k is 3. This means that as x increases or decreases, f(x) = 3x changes proportionally. The correct answer is therefore:
A. Direct variationTo further illustrate, consider two pairs of values for x and f(x):
if x = 2, then f(x) = 3(2) = 6,
And if x = 4, then f(x) = 3(4) = 12.
Notice that the ratio f(x)/x = 3 is constant.

Which of the following are measures of complementary angles? A. 50° and 41° B. 100° and 80° C. 77° and 13° D. 35° and 10°
Complimentary angles equal 90 degrees. So the answer would be C because 77+13= 90.
Answer: Two angles are complementary when they add up to 90°
then, doing all the options:
A) 50° + 41° = 91°, so this angles are non complementary.
B) 100° + 80° = 180°, so this aren't complementary, but they are Supplementary (because their addition is 180°) angles.
C) 77° + 13° = 90°, si this angles are complementary
D) 35° + 10° = 45°, this pair is not complementary.
So the only correct answer is C.

The values of x and y have been calculated as [tex]15[/tex] and [tex]12[/tex] respectively making option A the appropriate choice.
In the given question we can see that the angles [tex]62[/tex] degrees and [tex]4x + 2[/tex] degrees are alternate interior angles because they are alternately on the interior side of two parallel lines and transversal. hence, we can calculate x as:
[tex]62 = 4x + 2\\4x = 60\\x = 60/4 = 15[/tex]
Similarly, we can find the value of y as the angles [tex]12y[/tex] degrees and [tex]144[/tex] degrees are alternate interior angles.
[tex]12y = 144\\y = 144/12\\y = 12[/tex]
