Answer:

20%

Step-by-step explanation:

old selling price = $720

new selling price = 720 x (1 - 30%) = 720 x 70% = $504

cost = $420

markup = (504 - 420)/ 420 = 84/420 = 20%

Step-by-step explanation:

      We can use the distance formula to solve.

[tex]\displaystyle d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}[/tex]

[tex]\displaystyle d=\sqrt{(4--3)^2 +(1-2)^2}[/tex]

[tex]\displaystyle d=\sqrt{(4+3)^2 +(1-2)^2}[/tex]

because

8 18.40

5 ?

5×18.40=92

92÷8=11.5

Answer:

£11.50

Step-by-step explanation:

Well to solve this equation you must divide the total cost of the 8 sandwhiches by 18.40

18.40 divided by 8 is 2.30

So that means the cost per sandwhich is £2.30

Then all you have to do is multiply 2.30 by 5

2.30 divided by 5 is 11.50

So the cost of 5 sandwiches would be £11.50

Brief History:

While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. The distance between any point of a circle and the center of a circle is called its radius, while the diameter of a circle is defined as the largest distance between any two points on a circle. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle. All of these values are related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter, and is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as 22/7) and its decimal representation never ends or has a permanent repeating pattern. It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. Interestingly, the proof by Ferdinand von Lindemann in 1880 that π is transcendental finally put an end to the millennia-old quest that began with ancient geometers of "squaring the circle." This involved attempting to construct a square with the same area as a given circle within a finite number of steps, only using a compass and straightedge. While it is now known that this is impossible, and imagining the ardent efforts of flustered ancient geometers attempting the impossible by candlelight might evoke a ludicrous image, it is important to remember that it is thanks to people like these that so many mathematical concepts are well defined today.

Answer:

Rule:  Reflect the figure across the y-axis then translate the reflected figure 4 units to the right.

Step-by-step explanation:

Points of Figure A:

(2, 2)

(8, 4)

(6, 8)

Draw a line at x = 2, then reflect each point across the line

(2, 2) → (2, 2)

(8, 4) → (-4, 4)

(6, 8) → (-2, 8)

Reflection in the y-axis:  (x, y) → (-x, y)

As the y-values of our two figures have not changed, the first part of the rule is: reflect across the y-axis

If we reflect the figure across the y-axis, the points of the reflected figure are:

(-2, 2)

(-8, 4)

(-6, 8)

To bring the reflected figure back to where we want it (reflection in x = 2) we need to translate the figure 4 units to the right:

(-2 + 4, 2) = (2, 2)

(-8 + 4, 4) = (-4, 2)

(-6 + 4, 8) = (-2, 8)

So the final rule is:

Reflect the figure across the y-axis then translate the reflected figure 4 units to the right.

How do you find the speed of a falling object?

Calculate the final free fall speed (just before hitting the ground) with the formula v = g*t = 9.80665 * 8 = 78.45 m/s. Find the distance traveled by the falling object, using the equation s = 0.5 * g * t^2 = 0.5 * 9.80665 * 8^2 = 313.8 m.

The area of a 2D form is the amount of space within its perimeter. The area of the bottom of the box is 64 square inches.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.

Given the radius of the base of the plastic bottle is 2 inches, and there are four bottles arranged as shown below, therefore, the area of the bottom of the box is,

[tex]\rm \text{Area of the bottom of the box} = 8 \times 8 = 64\ in^2[/tex]

Hence, the area of the bottom of the box is 64 square inches.

The probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Total ways of choosing 3 out of 10 = C(10, 3) = 120

Total outcomes = 120

Total favorable outcomes = 3(Joseph, Heidi, and Katy)

Probability = 3/120 = 1/40

Thus, the probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.
