A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent. A circle is also known as the location of points that are evenly spaced out from the centre. A circle's radius is calculated by measuring it from the centre to the edge.The line that splits a circle into two identical halves is its diameter, which is also twice as wide as its radius.A circle's radius may be measured, making it a basic 2D shape.The inner and exterior parts of the aircraft are separated by the circles.

Answer:

hope this helps.

Step-by-step explanation:

The restaurant would make more money by slicing each pizza into sixths. The restaurant would make $36 more than if they sliced each pizza into fourths.

To determine if the restaurant would make more money by slicing each pizza into fourths or sixths, we need to calculate the total amount of money they would make for each option.

Option 1: Slicing each pizza into fourths

Option 2: Slicing each pizza into sixths

Comparing the two options, we can see that the restaurant would make more money by slicing each pizza into sixths. They would make $144 - $108 = $36 more by slicing each pizza into sixths instead of fourths.

Answer: When Mohammed meets Han Fei, she will be 74.6 kilometers away from San Francisco.

Step-by-step explanation:

First, we need to convert Mohammed's speed from miles per hour to kilometers per hour, as Han Fei's speed is given in kilometers per hour.

40 miles per hour = 64.37 kilometers per hour (approximately)

Now, let's determine how long it will take Mohammed to reach the point where he meets Han Fei:

time = distance ÷ speed

time = 240 km ÷ 64.37 km/h

time ≈ 3.73 hours

So, after 3.73 hours, Mohammed will meet Han Fei.

In that time, Han Fei will have traveled:

distance = speed × time

distance = 20 km/h × 3.73 h

distance ≈ 74.6 km

Answer:

Step-by-step explanation:

648 / 144 = 4.5

The room can accommodate 4.5 students.

Answer:

141 cm^2

Step-by-step explanation:

Given: V = 104 cm3, h = 8 cm

Since V = Bh, where B is the area of the base, and h is the height of a prism, then

B = V/h substitute the given values:

B = 104 cm3/8 cm

B = 13 cm2, which tells us that the long side of the square base equals the square root of 13.

The surface area of a prism = L.A. + 2B, where L.A. is the lateral area of the prism.

L.A. = pH, where p is the perimeter of the base.

Since p = 4(square root of 13) cm, h = 8cm, and B = 13 cm2, we have:

Surface Area = pH + 2B = [4(square root of 13) cm](8 cm) + 2(13 cm2) = 115.38 cm2 + 26 cm2 = 141 cm2

Thus, the surface area of the prism is approximately 141 cm2.

The measure of angles ∠DEM and ∠MEF will be the same which is 41.8 degrees.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Adjacent angle - In math, two points are nearby in the event that they have a typical side and a typical vertex.

EM bisects DEF and ∠DEF = 83.6°. Then the measure of the angle ∠DEM and ∠MEF will be the same. Then we have

∠DEM + ∠MEF = ∠DEF

∠DEM + ∠DEM  = 83.6°

2∠DEM = 83.6°

∠DEM = 41.8°

The measure of angles ∠DEM and ∠MEF will be the same which is 41.8 degrees.

Answer:

354 m

Step-by-step explanation:

to find the height substitute t = 3.5 into the height polynomial

height = - 16(3.5)² + 550 = - 16(12.25) + 550 = - 196 + 550 = 354

Graphically, the feasible solutions represent the points in the x-y plane that are inside the region defined by the three lines, and they can be found by plotting the three lines and shading the region below each line. The feasible solutions are the points in the shaded region that are common to all three.

Let x be the number of cubic yards of mix A used, and y be the number of cubic yards of mix B used. Then the total amount of phosphoric acid, nitrogen, and potash can be expressed as follows:

Phosphoric acid: 20x + 10y >= 460

Nitrogen: 30x + 30y >= 960

Potash: 5x + 10y >= 220

These inequalities represent the minimum monthly requirements for phosphoric acid, nitrogen, and potash. To find the feasible solutions, we need to find the values of x and y that satisfy all three inequalities simultaneously. This can be done graphically by plotting the three inequalities on the same coordinate plane and finding the region that is common to all three.

To plot the inequalities, we can choose convenient values for x and y, substitute them into the inequalities, and find the corresponding values of the right-hand side. For example, if we choose x = 0 and y = 0, then we have:

Phosphoric acid: 20 * 0 + 10 * 0 >= 460

Nitrogen: 30 * 0 + 30 * 0 >= 960

Potash: 5 * 0 + 10 * 0 >= 220

which gives us:

Phosphoric acid: 0 >= 460

Nitrogen: 0 >= 960

Potash: 0 >= 220

These values are all negative, which means that x = 0 and y = 0 do not satisfy the inequalities.

Next, we can choose x = 1 and y = 0, then we have:

Phosphoric acid: 20 * 1 + 10 * 0 >= 460

Nitrogen: 30 * 1 + 30 * 0 >= 960

Potash: 5 * 1 + 10 * 0 >= 220

which gives us:

Phosphoric acid: 20 >= 460

Nitrogen: 30 >= 960

Potash: 5 >= 220

These values are also negative, which means that x = 1 and y = 0 do not satisfy the inequalities either.

We can continue this process until we find values of x and y that satisfy all three inequalities. The feasible solutions are the values of x and y that satisfy all three inequalities, and they are represented by the region in the x-y plane that is common to all three. The feasible solutions can be found by shading the region below each of the lines representing the inequalities, and the set of feasible solutions is the region that is common to all three shaded regions.

The inequality is 25x + 60y + 180 ≤ 2500. x and y are variables.

What is inequality?

In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal symbol (≠)" to indicate that two values are not equal. But various inequalities are used to compare the values, whether it is less than or greater than.

Given that a 180-pound person has a load of boxes to deliver. There are types of boxes. The weight of the first type of box is 25 pound and the second type of box is 60 pounds.

Let x represent the number of​ 25-pound boxes, and let y represent the number of​ 60-pound boxes.

The weight of x number of boxes is 25x

The weight of y number of boxes is 60y

The person carrying the box means he is also in the elevator.

The total weight of the boxes and the person is 25x + 60y + 180.

The elevator can hold a maximum weight of​ 2,500 pounds.

The wight of the boxes and the person must be less than or equal to 2500 pounds.

The length and width of the rectangular board is 27 inches and 23 inches respectively

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the mat be = 184 inches²

Area of Rectangle = Length x Width

Substituting the values in the equation , we get

Let the area of the larger rectangle be = ( 2x - 3 ) ( x + 8 )

Let the area of the smaller rectangle be = ( 2x - 7 ) ( x + 4 )

Now , the area of mat = area of the larger rectangle - area of the smaller rectangle

So , 184 = ( 2x - 3 ) ( x + 8 ) - ( 2x - 7 ) ( x + 4 )

On simplifying the equation , we get

2x² - 3x + 16x - 24 - [ 2x² + x - 28 ] = 184

On further simplification , we get

12x + 4 = 184

Subtracting 4 on both sides of the equation , we get

12x = 180

Divide by 12 on both sides of the equation , we get

x = 15

So , the length of the board = ( 2x - 3 ) = 27 inches
