The area of the resulting two-dimensional cross-section of the pyramid geometry will be 5 square inches.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

What is an area in math definition

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. Take a pencil and draw a square on a piece of paper. It is a 2-D figure. The space the shape takes up on the paper is called its Area. Now, imagine your square is made up of smaller unit squares

A slice is made parallel to the base of a right rectangular pyramid, as shown.

Then the area of the resulting two-dimensional cross-section will be

Area = 2 in × 2.5 in

Area = 5 in²

A graph of the image of the triangle with vertices (4, 7), (3, 4), and (8, 2) after a transformation with the rule (x, y) → (−x, y) is shown in the image attached below.

In Geometry, a reflection over the y-axis (y = x) is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of this triangle the image coordinates include the following:

(x, y)                               →              (-x, y)

Coordinate A = (4, 7)   →  Coordinate A' = (-(4), 7) = (-4, 7).

Coordinate B = (3, 4)   →  Coordinate B' = (-(3), 4) = (-3, 4).

The volume of a hemisphere with a radius of 44.9 m is approximately 189582.2 cubic meters, rounded to the nearest tenth.

To calculate the volume of a hemisphere, you can use the formula

V = (2/3)πr^3

where V is the volume, π is pi (approximately 3.14), and r is the radius. In this case, r = 44.9 m.

So, (2/3)π(44.9)^3 = 189582.234 cubic meters.

This is the exact volume, but since the question asked for the volume rounded to the nearest tenth, the final answer would be 189582.234 cubic meters. It's worth mentioning that a hemisphere is half of a sphere, thus, the volume of a full sphere with a radius of 44.9 m would be double of this value.

Therefore , the solution of the given problem of linear equation comes out to be  $105 is the total cost

A linear regression model is one that uses the equation y=mx+b. The slope is B, and the y-intercept is m. The preceding sentence is commonly referred to as a "math equation with two variables," despite the fact that both y and x are separate factors. The only variables in bivariate linear equations are two. In all circumstances, the solutions to linear equations' application domains are zero. Y=mx+b is the formula for a single linear equation.

Here,

The first company's equation is y = 10.5x.

Additionally, the second company's equation is y = 7.5x + 30.

Where

number of T-shirts equals x.

y = overall cost

For the overall cost to be the same for both businesses, we have to:

=> 10.5x = 7.5x + 30

=> 10.5 x - 7.5 x = 30

=> 3 x = 30

=> x = 30/3

=> x = 10

To make the T-shirts' prices equal, the volleyball team must purchase 10 from each vendor.

Total for each business:

=> 10.5x = 10.5 (10) = $ 105

OR

Totals for each company are calculated as follows:

=> 7.5x + 30 = 7.5(10) + 30 = 75 + 30

=> $105

Therefore , the solution of the given problem of linear equation comes out to be  $105 is the total cost.

The equation 291 = 359 + 125m represents the given phrase, and the required value of m is 2.33

Algebra is a discipline of mathematics that deals with symbols and the rules that govern their use. These symbols, known as variables in elementary algebra, indicate quantities with no set values. Equations in mathematics express relationships between variables in the same way that sentences indicate relationships between specific words.

The equation 291 = 359 + 125m can be solved for m by subtracting 359 from both sides, resulting in:

291 - 359 = 125m - 359

-68 = 125m - 359

Adding 359 to both sides gives:

-68 + 359 = 125m

291 = 125m

Dividing both sides by 125 gives the solution for m:

291 / 125 = 125m / 125

2.33 = m

So, m is equal to 2.33.

The correct option is A, the linear equation has no solutions.

Here we want to see how many solutions do the equation below has:

(1/4)*(8 - 24x) = 12 - 6x

Now let's try to solve that linear equation, we can start by simplifying the left side:

(1/4)*(8 - 24x) = 12 - 6x

8/4 - 24x/4 = 12 - 6x

2 - 6x = 12 - 6x

Now we can add 6x in both sides, so we will get:

2 - 6x + 6x = 12 - 6x + 6x

2 = 12

That is a false equation, thus, the equation has no solutions.

To find the volume of the cereal box, we multiply the length, width, and height:

12 inches * 7 and 3/4 inches * 2 inches = 96 inches * 7.75 inches * 2 inches = 1458 cubic inches

To find the volume of the pastry box, we multiply the length, width, and height:

3 and 2/3 inches * 3 and 1/2 inches * 2 and 1/3 inches = 3.666 inches * 3.5 inches * 2.333 inches = 25.158 cubic inches

To find the difference in volume between the two boxes, we subtract the volume of the pastry box from the volume of the cereal box:

1458 cubic inches - 25.158 cubic inches = 1432.842 cubic inches

So the difference in volume between the two boxes is 1432.842 cubic inches.

Answer: The average rate of change over the interval 12 < x < 30 is -4/3

Step-by-step explanation:

The average rate of change over an interval is defined as the change in the output (f(x)) divided by the change in the input (x) over that interval. In this case, the interval is 12 < x < 30. To find the average rate of change, we need to evaluate the function at the endpoints of the interval and subtract the value at the start point from the value at the end point, and divide that by the change in x.

Given the table:

f(30) = 16 and f(12) = 40

The average rate of change over the interval 12 < x < 30 is:

(f(30) - f(12)) / (30 - 12) = (16 - 40) / 18 = -24/18 = -4/3

So the average rate of change over the interval 12 < x < 30 is -4/3

It's worth noting that this is only the average rate of change, and the function may have different rates of change at different points within the interval 12 < x < 30.

Since, Four distinct fair coins are tossed. if it is known that at least one of the coins shows a head . The probability that all coins show heads is 3/4.

Probability:

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes for an event. In an experiment with 'n' outcomes, the number of favorable outcomes can be denoted by x. The formula for calculating the probability of an event is:

  Probability (Event) = Favorable Outcome / Total Outcome = x/n

The probability of an event can be calculated using the probability formula by simply dividing the number of favorable outcomes by the total number of possible outcomes. The value of the probability that an event will occur can range from 0 to 1. This is because the preferred number of outcomes can never exceed the total number of outcomes. Also, the resulting favorable number can never be negative.

Given that:

Four District fair coins are tossed.

So, possible outcomes are
