The height of a cone with a diameter of 12 m whose volume is 340 m^3 is 9m

The height of a cone is calculated using the formula:

h = 3V/πr 2

Where h = height of the cone

V = volume of the cone

r = Radius of the cone

But note that radius, r = diameter divided by 2

r = 12 ÷ 2 = 6m

Volume = 340 m^3

Substitute the values into the formula

h = 3 × 340 ÷ 3.14 × 6 × 6

h = 1020 ÷ 113.04

h = 9m

Therefore, the height of a cone with a diameter of 12 m whose volume is 340 m^3 is 9m

The percentage of students who have grade point averages between 1.28 and 3.92 is therefore 99.7%.

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.6 and a standard deviation of 0.44.

Using the empirical rule, the percentage of the students who have grade point averages between 1.28 and 3.92 is 99.7%.

The empirical rule, which is often known as the three-sigma rule, states that in any normal distribution of data, the following percentage of data will be within one, two, or three standard deviations of the mean:-

68.27% of the data will lie within one standard deviation of the mean.- 95.45% of the data will lie within two standard deviations of the mean.- 99.73% of the data will lie within three standard deviations of the mean.

For this question, we want to know what percentage of students have grade point averages between 1.28 and 3.92, which is two standard deviations below and above the mean.

Using the empirical rule, we know that approximately 95% of the data will fall within two standard deviations of the mean, so 95% of the students will have grade point averages between (2.6 - 0.88) = 1.72 and (2.6 + 0.88) = 3.48. However, we want to know what percentage of students fall within the range of 1.28 to 3.92, which is slightly beyond two standard deviations from the mean. Since the empirical rule only provides estimates, we can assume that the additional percentage of students who fall beyond two standard deviations from the mean is roughly 2.5% on each side.

Therefore, the percentage of students who have grade point averages between 1.28 and 3.92 is approximately 95% + 2.5% + 2.5% = 99%.

She spent 7 minutes on her math homework.

Step-by-step explanation:

The number is -14 because it is even and less than -12. The absolute value of -14 is between 9 and 15. These conditions fulfill all the given clues.

Jia has given three clues about the number she's thinking of. The first clue is that the number is even, which means it is a multiple of 2. The second clue is that the number is less than -12. This means that the number is a negative number and it lies between -12 and -9 (because the absolute value of a number between -12 and -9 is between 9 and 12). The third clue is that the absolute value of the number is between 9 and 15. This condition is only satisfied by the number -14, which is even, negative, and has an absolute value between 9 and 15. Therefore, the answer is -14.

Based on the given clues, the number Jia is thinking of must be an even number that is less than -12 and whose absolute value is between 9 and 15. The only number that meets all three criteria is -14, which is an even number, less than -12, and has an absolute value of 14, which falls between 9 and 15. Therefore, we can conclude that Jia's number is -14.

The largest possible volume of the box is 480 cm³.

Given that 2400 square centimeters of material is available to make a box with a square base and an open top.

To find the largest possible volume of the box, we need to maximize the volume. We can express the volume of the box in terms of its side length.

Let's say the side length of the square base is x cm. The area of the square base will be x² square cm. Since the box has no top, we can say that its height is also x cm. So, the volume of the box can be expressed as,

V(x) = x² × x = x³ cubic cm

We know that 2400 square cm of material is available to make the box. The material is used to create the sides of the box. The box has 5 sides - four walls and a base. The area of the four walls will be the same. So, the total area of the four walls can be expressed as, 4xh = 4x², where h is the height of the box.

Subtracting this area from the total available material, we get the area of the base, which is equal to the area of the remaining material, 2400 - 4x² = x²

Simplifying, 5x² = 2400x² = 480

Volume of the box, V(x) = x³cubic cm

Substituting x = 12 in the expression for V(x), we get the maximum volume of the box, 480 cm³. Therefore, there is a maximum volume of 480  cm³ for the box.

Step-by-step explanation:

There are 12 coins, such that 6 are real, weighing 10 grams each, and 6 are fake, weighing 9 grams each. you have a scale that shows the exact weight of the coins on it. one of the two coins that were left out is heavier and the other is lighter.

Take 4 coins out of the pile and put them on one side of the balance scale. Take another 4 coins out of the pile and put them on the other side of the balance scale.

If both sides of the scale are equal, you know the remaining 4 coins contain the two coins of different weights you are looking for. In that case, take two coins out of the remaining 4 and weigh them on the balance scale. If they balance each other, the other two coins must be the ones of different weight. On the other hand, if the two coins on the balance scale don’t balance, you can be certain that one is real and the other is fake. In that case, you have already found the two coins you were looking for.

If the balance scale does not balance in the first weighing, you will know that the two coins of different weights must be contained in the group of 4 that is heavier or the group of 4 that is lighter. Remove two coins from the heavier pile, and place them on one side of the scale, and keep the other two on the other side. If the balance scale is still unbalanced, it means that the coin that is heavier is one of the two coins on the heavier side of the scale, and the coin that is lighter is one of the two coins on the lighter side. If the balance scale is now balanced, it means that one of the two coins that were left out is heavier and the other is lighter.

The cost per game ticket is 0.75. The solution has been obtained by using the linear equations.

What is a linear equation?

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. Several variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables.

We are given that Clayton and Iris purchase admission to a carnival plus a number of game tickets.

Let the admission cost be 'x' and cost per game ticket be 'y'.

Since, Clayton purchases 10 game tickets and spends $19.50 so, we get an equation in two variables as:

x + 10y = 19.50

Similarly, Iris purchases 15 game tickets and spends $23.25 so, we get first order equation as:

x + 15y = 23.25

Now, on subtracting the first equation from the second, we get

⇒ 5y = 3.75

⇒ y = 0.75

Hence, the cost per game ticket is 0.75.

The area of the shaded region of the ring is approximately 1600.36 square feet.

A circle's size may be determined using both its radius and diameter. The circumference of a circle, measured from centre to centre, is its diameter. The radius is the separation between any point on a circle's perimeter and its centre. In other words, the diameter is equal to the radius's length times two. This connection may be mathematically expressed as d = 2r, where d is the diameter and r is the radius. While the radius is frequently employed in computations involving circles, such as determining the area or circumference, the diameter is frequently used to describe the size of a circle.

The area of the circle is given by the formula:

A = πr²

For the inner circle we have:

radius = 36/2 = 18

A = π(18)²

For the outer circle we have:

radius = 44/2 = 22 ft.

A = π(22)²

Now, the area of the shaded portion is:

A = π(22)² - π(18)²

A = π(484) - π(324)

Substituting 3.14 for π we have:

A = 1600.36 square feet

Hence, the area of the shaded region is approximately 1600.36 square feet.

Answer: The transformation r y=x reflects the point (x, y) across the line y = x, and the transformation T -3,3 translates the point (x, y) three units to the left and three units up. To find the image point of (-8, 2) after these transformations, we can follow these steps:

Apply the reflection r y=x to the point (-8, 2):

(-8, 2) reflects to (2, -8).

Apply the translation T -3,3 to the reflected point (2, -8):

(2, -8) translates to (-1, -5).

Therefore, the image point of (-8, 2) after the transformation r y=x T -3,3 is (-1, -5).

Considering the definition of perpendicular line, the correct answer is option 2.: the equation of a line perpendicular to y = 2x + 5 and passing through the point (8,2) is y= -1/2x +6.

A linear equation o line can be expressed in the form y = mx + b

where

Perpendicular lines are lines that intersect at right angles. If you multiply the slopes of two perpendicular lines, you get –1.

The line is y= 2x +5

where:

If you multiply the slopes of two perpendicular lines, you get –1. So:

2× slope perpendicular line= -1

slope perpendicular line= (-1)÷ 2

slope perpendicular line= -1/2

The line passes through the point (8, 2). Replacing in the expression for perpendicular line:

2= -1/2× 8 + b

2= (-4) + b

2 +4 = b

6= b
