A can of beans has surface area 354 cm². Its height is 20 cm. What is the radius of the circular top? The radius of the circular top is cm (Do not round until the final answer. Then round to the nearest hundredth as needed​

Answers

Answer 1
The surface area of a cylinder with height h and a circular top with radius r is given by the formula:

A = 2πr^2 + 2πrh

We know the surface area, so we can use this formula to find the radius of the circular top:

354 = 2πr^2 + 2πrh
354 = 2πr^2 + 40πr
354 = 2πr^2 + 40πr
354 = 2πr(r + 20)

We can now solve for r:

354 = 2πr(r + 20)
177 = πr(r + 20)
177 = πr^2 + 20πr
177 = πr^2 + 20πr
πr^2 + 20πr - 177 = 0

We can use the quadratic formula to find the value of r:

r = (-b ± √(b^2 - 4ac)) / 2a

Where a = π, b = 20π, c = -177

r = (-20π ± √(20^2 - 4(π)(-177))) / (2 * π)
r = (-20π ± √(400π^2 + 708)) / (2 * π)
r = (-20π ± √(708 + 400π^2)) / (2 * π)
r = (-20π ± √(708 + 400 * π^2)) / (2 * π)

Since the radius must be positive, we'll use the positive square root:

r = (-20π + √(708 + 400 * π^2)) / (2 * π)

Using the value of π = 3.14, we can calculate the value of r to be approximately 6.93 cm. Rounding to the nearest hundredth, we get:

r = 6.93 cm (rounded to the nearest hundredth)

the students in mr. juarez's homeroom collected more cans than students in ms. wade's homeroom. write an expression that represents how many more cans were collected.

Answers

The expression that can represent how many more cans were collected is 8n - 7 > 6n + 3, which is in fact an inequality.

An inequality in math is an algebraic expression that represents, well, inequality. It shows a relationship between two values or expression, which aren't equal to each other. It is used to compare two values/expression, showing if one is greater than, less than, or simply not equal to another. Thus, we would use a mathematical symbol of <, >, ≤, ≥, or ≠ to express an inequality.

Since students in Mr. Juarez's homeroom collected more cans than students in Ms. Wade's homeroom do, you can use the symbol > in your inequality. The number of cans collected in Mr. Juarez's homeroom is 8n − 7, while the number of cans collected in Ms. Wade's homeroom is 6n + 3. Therefore, your inequality would be 8n - 7 > 6n + 3.

what are the measures of the angels in the right triangles formed by the two regular pentagons are

Answers

The measures of the angles in the right triangle formed by the two regular pentagons are 18 degrees and 72 degrees.

Right triangles and regular pentagons

The interior angles of a regular pentagon measure 108 degrees each. Therefore, if we have two regular pentagons, the right triangle formed by the two pentagons will have two angles that are equal to 108 degrees each.

These two angles are the complement of each other, meaning they add up to 90 degrees. Therefore, one of the angles in the right triangle formed by the two pentagons is 72 degrees, and the other is 18 degrees.

Answers

Answer:

£ 3125

Step-by-step explanation:

Tax amount on  £ 2665 = 20% of 2665

                                       = 0.2 * 2665

                                       =  £ 533

Rest amount = 3672 - (972 + 2665)

                     = 3672 -3637

                     =  £ 35

Tax amount of  £ 35 = 40% * 35

                                 = 0.4 * 35

                                 = 14

Total tax = 533 + 14

The vertex form of quadratic equation is y = a(x - 0)² + 7 and the standard form of quadratic equation is y = 0x² + 7

What do you mean by Vertex form?

The vertex form of a quadratic equation is an equation written in the form:

f(x) = a(x - h)² + k,

where (h, k) is the vertex of the parabola represented by the equation. The variable x represents the input value, f(x) represents the output value, a represents the coefficient of the x² term, h represents the x-coordinate of the vertex, and k represents the y-coordinate of the vertex. The vertex form of a quadratic equation is useful for easily identifying the location and shape of the parabola represented by the equation, especially if the parabolic function has a vertex that is not at (0,0).

The vertex form of a quadratic equation is given by y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

To find the vertex form of this equation, we need to find the vertex first. To do this, we can average the x-values of the maximum and minimum points in the table, which gives us the x-coordinate of the vertex. In this case, the maximum and minimum points are (1, 7) and (-1, -9), so the x-coordinate of the vertex is (1 + -1)/2 = 0.

Next, we can find the y-coordinate of the vertex by evaluating f(0), which gives us 7.

So, the vertex of the parabola is (0, 7).

Using this information, we can write the vertex form of the equation:

y = a(x - 0)² + 7

To find the standard form of the equation, we need to expand the vertex form and simplify.

y = a(x² - 0x) + 7

y = ax² + 7

We can then find the value of a by using any one of the points in the table. Let's use the point (1, 7):

7 = a(1²) + 7

7 = a + 7

a = 0

So, the standard form of the equation is:

y = 0x² + 7

Using Pythagorean theorem and the vertices given, the two triangle are similar

What are vertices of a triangle

Two triangles are similar if and only if the ratios of their corresponding sides are equal. So, to determine if triangle ABC is similar to triangle XYZ, we need to compare the ratios of corresponding sides.

One way to do this is to calculate the lengths of the sides in both triangles and compare the ratios. For example, the length of side AB in triangle ABC can be found using the Pythagorean theorem:

AB = √((0-(-3))^2 + (10-6)^2) = √(3^2 + 4^2) = √25 = 5

Similarly, the length of side XY in triangle XYZ can be found:

XY = √((2-(-1))^2 + (7-3)^2) = √(3^2 + 4^2) = √25 = 5

Next, we can compare the ratios of corresponding sides AB and XY, BC and YZ, and AC and XZ. If the ratios are equal for all corresponding sides, then the triangles are similar.

In this case, we find that the ratios of corresponding sides AB and XY, BC and YZ, and AC and XZ are all equal, so triangles ABC and XYZ are similar.

Subtract and reduce to lowest terms: 3 1/4 - 1 1/8
A. 2 1/8
B. None
c. 2 0/4
d. 17/8

Answers

The correct answer is option A. 2 1/8 when reduced to the lowest terms.

To subtract 3 1/4 - 1 1/8, we need to convert the fractions to a common denominator. The common denominator for 3 1/4 and 1 1/8 is 8. To convert 3 1/4 to 8, we multiply both the numerator and denominator by 2, resulting in 6/8. To convert 1 1/8 to 8, we multiply both the numerator and denominator by 8, resulting in 8/8.

Now we have two fractions with a common denominator of 8. To subtract them, we subtract the numerators and keep the same denominator. We have 6/8 - 8/8, which is -2/8. To reduce this fraction to the lowest terms, we divide the numerator and denominator by the greatest common factor (GCF), which is 2. -2/8 divided by 2 is -1/4. Finally, we add -1/4 to 1 1/8 to get the answer 2 1/8.

There is a bag filled with 5 blue and 4 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 of the same colour?

Answers

The probability of getting 2 same colour balls in a row = 41/81

Probability:

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us.

Probability of an event P(E)

= [ No of favorable outcomes ]/ Total No of outcomes

Here we have

There is a bag filled with 5 blue and 4 red marbles.  

Number of balls = 5 + 4 = 9  

Marble is taken at random from the bag,

The probability of getting the red ball = 4/9  

The probability of getting the blue ball = 5/9

The color is noted and then it is replaced.

Another marble is taken at random.  

The probability of getting the red ball 2nd time = 4/9  

The probability of getting the blue ball 2nd time = 5/9    

The probability of getting red ball in 2 attempts = (4/9)(4/9) = 16/81

The probability of getting blue ball in 2 attempts = (5/9)(5/9) = 25/81  

Hence the probability of getting 2 of the same color

= 16/81 + 25/81

= 41/81  

Therefore,

The probability of getting 2 same colour balls in a row = 41/81

what is the length of the line? the first quadrant of an x- y- coordinate plane. a line segment extends from two, eight to twelve, two.

Answers

The length of the line segment is approximately 12.04 units. This formula calculates the distance between two points, (x1, y1) and (x2, y2), on the line segment. The formula is as follows: d = √((x2 - x1)^2 + (y2 - y1)^2)

The length of a line segment in a two-dimensional x-y coordinate plane can be found using the distance formula. This formula calculates the distance between two points, (x1, y1) and (x2, y2), on the line segment. The formula is as follows:

d = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, the line segment extends from the point (2, 8) to the point (12, 2). By plugging these values into the formula, we find that:

d = √((12 - 2)^2 + (2 - 8)^2) = √(100 + 36) = √136 = 12.04

So, the length of the line segment is approximately 12.04 units. This formula is useful for finding the distance between any two points in a two-dimensional plane and can be used in various fields such as geometry, physics, and engineering. The formula is based on 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.

what is inequality ?

A relationship of two expresses or integers that is neither equal in mathematics is referred to as an inequality. Furthermore, inequity results from imbalance. In math and science, an inequalities establishes the connection between two ou alors elements. Egality and inequality are not the same. Use the not equal symbol most frequently when two quantities are not equal (). Values of any size can be examined using a variety of inequalities. By changing the two sides until only the variables are left, many straightforward inequalities can be solved. However, a number of factors support inequality: Both sides' 0 are split or added. Exchange the left and the right.
