Explain the Error. A student said the volume of a cylinder with a 3- inch diameter is two times the volume of a cylinder with the same height and a 1.5 inch radius. What is the error?

Answer: square root of 89 units i think so

Step-by-step explanation:

The distance between the points (−2, −4) and (−7, −12) is √89 units.

Among the given options, the correct answer is "square root of 89 units."

To determine the distance between the points (−2, −4) and (−7, −12), we can use the distance formula. The distance formula calculates the distance between two points (x₁, y₁) and (x₂, y₂) in a Cartesian coordinate system.

The distance formula is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Let's substitute the coordinates of the given points into the formula:

d = √((-7 - (-2))² + (-12 - (-4))²)

= √((-7 + 2)² + (-12 + 4)²)

= √((-5)² + (-8)²)

= √(25 + 64)

= √89

Explanation

The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.

(angle ABD) + (angle DBC) = 180

(134) + (2x) = 180

2x = 180-134

2x = 46

x = 46/2

x = 23

Answer: x=23 and the angle relation used was supplementary angles

Step-by-step explanation:

first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Scroll Down Below...

Step-by-step explanation:

Part A: To record an equating defining this position, we can start by canny the total distance camouflaged in d supplementary days. Since the kin drives 350 5 per epoch each surplus era, the total distance marked in d supplementary days is 350d. Adding the beginning 200 5 compelled on the first epoch, the equating enhances:200 + 350d = 1,600Part B: To resolve the equating and find the total number of days the offspring will travel, we need to detach the changeable d. We can start by subtracting 200 from two together hands of the equating:350d = 1,600 - 200350d = 1,400Next, we separate two together parts of the equating by 350 to resolve for d:d = 1,400 / 350d = 4Therefore, the kin will travel for an supplementary 4 days to reach a total distance of 1,600 5.

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

Cube root of 75 + 50 = irrational

Answer:

The x-intercept is (-5, 0).

The y-intercept is (0, 5).

Step-by-step explanation:

To find the x-intercept, we set y = 0 and solve for x:

0 = 5 + x

x = -5

Therefore, the x-intercept is (-5, 0).

To find the y-intercept, we set x = 0 and solve for y:

y = 5 + 0

y = 5

Therefore, the y-intercept is (0, 5).

Answer:

x-intercept is (-5,0)

y-intercept is (0,5)

Step-by-step explanation:

We are given a linear equation and are asked to find the x- and y-intercepts of the equation.

\(\Huge{y=5+x\)

\(\hrulefill\)

In mathematics, the terms "x-intercept" and "y-intercept" refer to points where a graph intersects the x-axis and y-axis. They are important concepts in the study of functions and graphs.

The x-intercept is the point at which a graph crosses or intersects the x-axis. It represents the value of x when y is equal to zero. In other words, it is the value of x when the function or equation is satisfied with y = 0. The x-intercept is often denoted as (x, 0), where "x" is the x-coordinate of the point.

Similarly, the y-intercept is the point at which a graph crosses or intersects the y-axis. It represents the value of y when x is equal to zero. Geometrically, it is the point on the graph where x = 0. The y-intercept is often denoted as (0, y), where "y" is the y-coordinate of the point.\(\hrulefill\)

(1) - Finding the x-intercept

To find the x-intercept, you set y equal to zero and solve the equation for x.

\(y=5+x\\\\\\\text{Let y=0}\\\\\\\Longrightarrow 0=5+x\\\\\\\Longrightarrow \boxed{x=-5}\)

Thus, the x-intercept is (-5,0).

(2) - Finding the y-intercept

To find the y-intercept, you set x equal to zero and solve the equation for y.

\(y=5+x\\\\\\\text{Let x=0}\\\\\\\Longrightarrow y=5+0\\\\\\\Longrightarrow \boxed{y=5}\)

Thus, the y-intercept is (0,5).\(\hrulefill\)

The area of the fragment is \(10cm^{2}\) if each square on the grid has the area of \(1cm^{2}\).

We have been given the area of one square on the grid is \(1cm^{2}\).

We have to find the total area of the fragment.

Let's calculate the total area of the fragment.

We have been given the area of one square in the fragment is \(1cm^{2}\) .

Step 1: Count the number of squares present in the fragment.

Adding the number of colored squares in the row,

= 4 + 3 + 2 + 1

= 7 + 3

= 10

Step 2: Multiplying the number of squares in a fragment by the area of one square.

Now, forming an expression to calculate the total area,

= Number of squares X Area of one square

Substituting the values,

= \(10(1cm^{2} )\)

= \(10cm^{2}\)

Therefore, the area of the fragment is \(10cm^{2}\)

Correct question: Find the area of the fragment, if each square on the grid has an area of \(1cm^{2}\).

The area of the fragment is approximately 10 cm².

Hence, option D is correct.

Use the concept of the triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

Gieven that,

Eeach grid has area = 1 cm²

Since each grid is of square shape,

Therefore,

Heigh of each grid = 1 cm

And the width of each grid = 1 cm

Now from the figure,

The height of the triangle = 4 cm

The width of the triangle ≈ 5 cm

Since knowing that,

Area of triangle = (1/2) x base x height

Therefore,

Area of the shaded region ≈ (1/2)x4x5

Area of the shaded region ≈ 10 cm²

Hence,

The area of the fragment is approximately 10 cm² which is option D.

Answer: The figure that has exactly one line of symmetry is B. Pentagon.

Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.

Using either method, we can see that:

A. Rhombus has two lines of symmetry: one diagonal and one vertical.

C. Rectangle has two lines of symmetry: one horizontal and one vertical.

D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.

B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.

Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.

Since we don't have an image of the rectangular prism or the sketches, we cannot determine the correct answer.

However, in order to find the length of the diagonal of a rectangular prism, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Therefore, if we have a right triangle whose two shorter sides are the dimensions of the rectangular prism, we can use the Pythagorean theorem to find the length of the diagonal.

If any of the sketches do not form a right triangle, or if they do not include the necessary dimensions of the rectangular prism, they cannot be used to find the length of the diagonal.
