the only cube number between 20 and 50 is 27.
Step 1: Find the smallest cube greater than 20.
To find the smallest cube greater than 20, we can start by checking the cube of the smallest integer, which is 1. Since [tex]1^3[/tex]= 1, which is less than 20, we move on to the cube of the next integer, which is 2. We find that [tex]2^3[/tex]= 8, which is still less than 20. Finally, we check the cube of the next integer, which is 3. We find that [tex]3^3[/tex]= 27, which is the smallest cube greater than 20.
Step 2: Find the largest cube less than 50.
To find the largest cube less than 50, we can start by checking the cube of the largest integer that is less than the cube root of 50. The cube root of 50 is approximately 3.68, so the largest integer less than the cube root of 50 is 3. We find that [tex]3^3[/tex] = 27, which is less than 50. Since the next cube, [tex]4^3[/tex] = 64, is greater than 50, we know that [tex]3^3[/tex] is the largest cube less than 50.
Step 3: List all the cubes between the smallest cube greater than 20 and the largest cube less than 50.
Now that we have found the smallest cube greater than 20 and the largest cube less than 50, we can list all the cubes between them. The cubes between 27 and 27 are just 27, so we have:27
Therefore, the only cube number between 20 and 50 is 27.

Describe Triangle?Triangles can be classified based on the lengths of their sides and the sizes of their angles. The three most common types of triangles are equilateral, isosceles, and scalene. In an equilateral triangle, all sides and angles are equal. In an isosceles triangle, two sides and two angles are equal. In a scalene triangle, all three sides and angles are different.
Let's call the two sides of the triangle that the median divides into 9 and 10 "a" and "b", respectively. Then, we can use the formula for the length of a median in a triangle:
median = 1/2 * √(2a² + 2b² - c²)
where c is the length of the third side of the triangle. However, we don't know the length of the third side, so we need to find it. We can use the fact that the median divides the third side into two equal parts:
c/2 = (a + b)/2
c = a + b
Now we can substitute this into the formula for the length of the median:
x = 1/2 * √(2a² + 2b² - (a + b)²)
Simplifying:
x = 1/2 * √(2a² + 2b² - a² - 2ab - b²)
x = 1/2 * √(a² + 2ab + b²)
x = 1/2 * √((a + b)²)
x = 1/2 * (a + b)
x = 1/2 * (9 + 10)
x = 9
So the length of the median is 9 units.

What is a triangle?A triangle is a clοsed, twο-dimensiοnal geοmetric shape that has three straight sides and three angles. It is οne οf the mοst basic shapes in geοmetry and is used extensively in mathematics, science, and engineering.
Tο sοlve fοr x, we can use the Pythagοrean theοrem which states that in a right triangle, the square οf the hypοtenuse (the side οppοsite the right angle) is equal tο the sum οf the squares οf the οther twο sides.
In this case, we can see that the hypοtenuse is 10 cm and οne οf the οther sides is x cm. The remaining side is then (10 - x) cm (since the triangle is isοsceles).
Applying the Pythagorean theorem, we get:
x² + (10 - x)² = 10²
x² + 100 - 20x + x² = 100
2x² - 20x = 0
2x(x - 10) = 0
So x = 0 or x = 10. However, x cannot be 0 since it would not form a triangle. Therefore, the only valid solution is x = 10.
Therefore, the length of the missing side is 10 cm.

Step-by-step explanation:
to graph a line always find 2 points out has to go through. that means the points' coordinates make the equation true.
I usually start with x = 0.
point 1 of equation 1 is then
y = -2×0 + 6 = 6
(0, 6)
point 1 of equation 2 is then
y = (3/2)×0 - 1 = -1
(0, -1)
then I pick a value for x that makes the handling of any fractions easier. like in our case x = 2.
point 2 of equation 1 is then
y = -2×2 + 6 = -4 + 6 = 2
(2, 2)
point 2 of equation 2 is then
y = (3/2)×2 - 1 = 3 - 1 = 2
(2, 2)
oh, so I have found the intersection point right away (point 2 of both equations).
so, let's pick a different point 2 for equation 1, like x = 4
y = -2×4 + 6 = -8 + 6 = -2
(4, -2)
with these 4 points you define the 2 lines, and you have the intersection point at (2, 2).
A population of values has a normal distribution withμ=178andσ=75.2. You intend to draw a random sample of sizen=48. Find the probability that a sample of sizen=48is randomly selected with a mean between182.3and 198.6.P(182.3×M<198.6)=Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exactz-scores orzscores rounded to 3 decimal places are accepted.
The probability that a sample of size n=48 has a mean between 182.3 and 198.6 is approximately 0.9474.
The central limit theorem: what is it?The behaviour of sample means and sums in sizable random samples is described by the central limit theorem, a statistical concept. It asserts that regardless of how the underlying population is distributed, as the sample size grows, the distribution of the sample means and sums will converge to a normal distribution. This theorem is crucial because it enables us to extrapolate population parameters from sample data. Because sample means and variances are simpler to gather and evaluate, we may use them to estimate population means, variances, and other characteristics. Several study fields, including the social sciences, the natural sciences, and business, frequently employ the central limit theorem.
Given that the sample size n = 48.
The mean between 182.3and 198.6 is calculated using the central limit theorem.
The sample mean is given as:
Z = (M - μ) / (σ / √(n))
Substituting the values we have:
Z = (198.6 - 178) / (75.2 / √(48)) - (182.3 - 178) / (75.2 / √(48))
Z = 1.62
Now, Z-score less than 1.62 is approximately 0.9474.
Hence, the probability that a sample of size n=48 has a mean between 182.3 and 198.6 is approximately 0.9474.

Mixes two varieties of saffron X and y the ratio 3:8 if the cost of X is rupees 154 per g and that of y is rupees 121 per gram at what price should he sell the mixture make a profit of 25%
The seller should sell the mixture at Rs. 162.5 per gram to make a profit of 25%.
Let's assume that the quantity of variety X in the mixture is 3x and the quantity of variety Y is 8x. Therefore, the total quantity of the mixture will be 3x + 8x = 11x.
The cost of variety X is Rs. 154 per gram. Therefore, the cost of 3x grams of variety X will be 3x × Rs. 154 = Rs. 462x.
Similarly, the cost of variety Y is Rs. 121 per gram. Therefore, the cost of 8x grams of variety Y will be 8x × Rs. 121 = Rs. 968x.
The total cost of the mixture will be the sum of the costs of the individual varieties:
Total cost = Rs. 462x + Rs. 968x = Rs. 1430x
To make a profit of 25%, the selling price of the mixture should be 1.25 times the cost price:
Selling price = 1.25 × Total cost
= 1.25 × Rs. 1430x
= Rs. 1787.5x
Therefore, the selling price of the mixture should be Rs. 1787.5x to make a profit of 25%. To find the price per gram of the mixture, we need to divide this selling price by the total quantity of the mixture:
Price per gram of mixture = Selling price / Total quantity
= Rs. 1787.5x / 11x

The volume, in cubic centimetres, of a rectangular box can be modelled by the polynomial expression 2x3−11x2−41x+140. Determine an equation to represent the area of the base of the box if the height, in centimetres, is given by 2x−5. [APP 3 marks]
The equation for area of the base of the box will be x² - 6x + 28.
What is Volume ?
In physics and mathematics, volume is a measure of the amount of three-dimensional space occupied by an object or a region. It is often measured in cubic units, such as cubic meters, cubic centimeters, or cubic feet.
The volume (V) of a rectangular box is given by the product of its length (l), width (w), and height (h):
V = lwh
Given that the volume is modelled by the polynomial expression 2x³- 11x² - 41x + 140, we can write:
V = 2x³ - 11x² - 41x + 140
And since the height is given by 2x - 5, we can substitute this expression into the formula for volume:
V = lwh = (lw)(2x - 5)
So we need to find an equation for the area of the base (lw). We can do this by rearranging the formula for volume:
lw = V / (2x - 5)
Substituting the expression for V, we get:
lw = (2x³ - 11x² - 41x + 140) / (2x - 5)
We can simplify this expression by polynomial long division or synthetic division, which gives:
lw = x² - 6x + 28
Therefore, the equation for the area of the base of the box is:
A = x² - 6x + 28, where A is the area in square centimeters, and x is the length in centimeters.

The function f(x) = –5x2 + 13x + 6 represents the height, in meters, of a coin x seconds after it is thrown into the air. What is the maximum height of the coin
The maximum height of the coin is approximately 14.825 meters.
To find the maximum height of the coin, we need to find the vertex of the parabolic function. The x-coordinate of the vertex is given by:
x = -b/2a
where a = -5 and b = 13 are the coefficients of the quadratic function f(x) = -5x^2 + 13x + 6.
Plugging these values into the formula, we get:

In the given triangle the value of the ratios are Sin (P) = 5/13. tan (T) = 12 /5. cos (T) = 5/13.
What are trigonometric identities?Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are several distinctive trigonometric identities that relate a triangle's side length and angle. Only the right-angle triangle is consistent with the trigonometric identities.
The six trigonometric ratios serve as the foundation for all trigonometric identities. Sine, cosine, tangent, cosecant, secant, and cotangent are some of their names. The adjacent side, opposite side, and hypotenuse side of the right triangle are used to determine each of these trigonometric ratios. The six trigonometric ratios are the source of all fundamental trigonometric identities.
Using the trigonometric identities we can write the ratios as follows:
Sin (P) = Opposite side to P / Hypotenuse= 5/13
tan (T) = Opposite side to T / Adjacent side to T = 12 /5
cos (T) = adjacent side to T / Hypotenuse = 5/13.

The trigonometric ratios for cosines indicates that the measure of angle B, m∠B, in the right triangle with hypotenuse side length of 15 units and adjacent leg to ∠B of 12 units, obtained using the trigonometric ratios for cosines is; m∠B ≈ 36.9°
What are trigonometric ratios?Trigonometric ratios relate the lengths of two side lengths of a right triangle and the interior angles of the right triangle.
The cosine of an angle can be obtained from the ratio of the adjacent side to the angle to the hypotenuse side of the right triangle in which the angle is an acute angle, therefore;
cos(θ) = Adjacent side to the angle ÷ Hypotenuse side of the angle
The measure of the length of the adjacent side to the angle x = 12 units
The measure of the hypotenuse side of the right triangle = 15 units, therefore;
cos(x°) = 12/15 = 4/5 = 0.8
The measure of the angle x therefore can be obtained using the arccos function, (cos⁻¹ function) in a scientific calculator as follows;
x = arccos(0.8) ≈ 36.9°
The measure of the angle x is about 36.9°Learn more on the trigonometric ratios of cosines here: https://brainly.com/question/13276558

A triangular piece of fabric has side lengths of 3 inches, 4 inches, and 5 inches. Will it fit in the corner of a rectangular quilt? Explain.
Yes, because it is a right triangle.
Yes, because it is an isosceles triangle.
No, because it is an equilateral triangle.
No, because it is an obtuse triangle.
Answer:
yes because it is a right triangle
Step-by-step explanation:
if you apply the pythagorean theorem a squared plus b squared equals c squared. c being the hypotenuse, the longest side. so 3x3 + 4x4 = 25 and 5x5 is 25. This confirms that it is a right triangle because pythagoras's theorem only works with right triangles. Also, every angle of a rectangle is a right angle (90 degrees) meaning that the triangle will fit in any and every corner! Hope this helped!
