For the given line segment, write the equation of the perpendicular bisector.

Answer:

c. 105 yd^2.

Step-by-step explanation:

First find the slant height (h) of each of the triangular walls:

tan 60 = h /  3.1

h = 3.1 tan 60

= 5.369 yds.

Area of each side = 3.1* 5.369

= 16.645

Total surface area of the pyramid

= 4 * 16.645 + 6.2^2

= 105.02 yd^2.

Answer:

Jody

Step-by-step explanation:

You can either convert 500 seconds to minutes or 8 minutes to seconds to compare. I'll do both.

There is 60 seconds in a minute. To find the total minutes of 500 seconds, divide 500 by 60 → 8.3, which means that Jody practiced for 8.3 minutes.

To find the total seconds of 8 minutes, multiply 60 seconds per minute by 8 minutes → 60 * 8 = 480 seconds which means that Bill practiced for 480 seconds.

Now you can compare. Jody practiced for 500 seconds, or 8.3 minutes. Bill practiced for 480 seconds, or 8 minutes. Jody practiced longer.

Answer:

2 and -1

Step-by-step explanation:

y = x^2 -x-2

To find the x intercept, set y = 0

0 = x^2 -x-2

Factor

What 2 numbers multiply to -2 and add to -1

-2*1 = -2

-2 +1 = -1

0 = (x-2) (x+1)

Using the zero product product property

x-2 = 0    x+1 =0  

x=2          x=-1

Answer:

When a card is chosen at random with replacement five times, X is the number of times a prime number is chosen; When a card is chosen at random with replacement six times, X is the number of times a 3 is chosen.

Step-by-step explanation:

In a binomial distribution, there are only two outcomes, or outcomes that can be reduced to 2.  In the first choice, we either draw a prime number or do not draw a prime number.  In the third choice, we either draw a 3 or do not draw a 3.

There must be a fixed number of trials.  In the first choice, we have 5 trials; in the third option, we have 6 trials.

The trials must be independent of each other.  Since the cards in the first and third options are drawn with replacement, the outcome of one trial does not influence the probability of the next trial.

The probability must be the same for every trial.  This is true of the first and third options.

Hence, the lakes' altitudes varied by 40 feet. To sum up: Average: around -26.3 feet, Average: -18 feet , Zero mode and 30 to 40 ft.

The mean, a statistic of central tendency in mathematics, is the average of a group of numerical values. It is also frequently known as the geometric average. A set of values' mean is calculated by adding up all of the values and dividing the result by the amount of values in the set. The mean can be determined, for instance, if the set of values is 3, 5, 7, 9, and 11, by multiplying the values together and dividing them by the total amount of numbers: Mean = (3 + 5 + 7 + 9 + 11) / 5 = 7 .As a result, 7 represents the set's mean value.

given

The median altitude of the lakes is -18 feet because the middle number is -18.

Mode: To identify the mode, we search the collection for the number that pops up the most often. There is no mode because no number appears more than once in this instance.

Range: To get the range, divide the largest by the smallest number:

Maximum number - smallest number equals the range (-9) - (-49) = 40

Hence, the lakes' altitudes varied by 40 feet. To sum up: Average: around -26.3 feet, Average: -18 feet , Zero mode and 30 to 40 ft.

Final answer:

Jason can cut 12 pieces of sausage from the 6-inch roll, since dividing the roll's length by the thickness of each piece (6 inches ÷ 1/2 inch) yields 12 pieces.

Explanation:

To determine how many pieces of sausage Jason can cut from a roll that is 6 inches long, where each piece is 1/2 inches thick, one would perform a simple division.

The length of the sausage roll (6 inches) is divided by the thickness of each piece (1/2 inch) to find out how many pieces can be cut.

This is a basic fraction division problem that we solve by multiplying the length of the roll by the reciprocal of the thickness of the pieces to be cut.

Calculation

To calculate:
6 inches × 2/1 (which is the reciprocal of 1/2) equals 12.

So, Jason can cut 12 half-inch-thick pieces from the 6-inch roll.

The missing number in the sequence 16...06...68...88...?...98 is 78

From the question, we have the following parameters that can be used in our computation:

16...06...68...88...?...98

When the number are flipped upside down, we have

91....90....89.....88......?.......86

In the above sequence, we can see that -2 is added to the previous term to get the new term

This means that the complete sequence is

Step-by-step explanation:

A transformation of T(a,b) in the equation would give this form:

Answer:

The answer is ellipse; 23° to the nearest degree ⇒ answer (d)

Step-by-step explanation:

* At first lets talk about the general form of the conic equation

- Ax² + Bxy + Cy²  + Dx + Ey + F = 0

∵ B² - 4AC < 0 , if a conic exists, it will be either a circle or an ellipse.

∵ B² - 4AC = 0 , if a conic exists, it will be a parabola.

∵ B² - 4AC > 0 , if a conic exists, it will be a hyperbola.

* Now we will study our equation:

- 9x² + 4xy + 5y² - 40 = 0

∵ A = 9 , B = 4 , 5 = 5

∴ B² - 4 AC = (4)² - 4(9)(5) = -164 < 0

∴ B² - 4AC < 0

∴ If a conic exists, it will be either a circle or an ellipse.

* To find the type of the graph lets check;

- If A and C are nonzero, have the same sign, and are not

 equal to each other, then the graph is an ellipse.

- If A and C are equal and nonzero and have the same

 sign, then the graph is a circle.

∵ A and C have same signs and are not equal

∴ The graph is an ellipse

* If we have term xy ⇒ B ≠ 0

∴ The graph is rotate by angle Ф

* To find the angle of rotation use the rule:

- cot(2Ф) = (A - C)/B

∵ A = 9 , B = 4 , C = 5

∴ cot(2Ф) = (9 - 5)/4 = 4/4 = 1

∴ tan(2Ф) = 1

∴ 2Ф = 45°

∴ Ф = 22.5° ≅ 23° to the nearest degree

* The answer is ellipse; with angle of rotation = 23°

The Zero Product Property in mathematics states that if the product of two numbers is zero, then at least one of the numbers must be zero. You typically use this property when solving quadratic equations by setting each factored term equal to zero and then solving for every variable.

The Zero Product Property is an essential concept in algebra, particularly when it comes to solving quadratic equations. The Zero Product Property states that if the product of two numbers, terms, or factors is zero, then at least one of the factors must be zero. In simple terms, if a * b = 0, then a has to be zero, or b has to be zero, or both.

To use the Zero Product Property, you usually start by setting an equation equal to zero. For example, let's solve the quadratic equation x^2 - 5x = 0. First, you would factor the equation to (x)(x-5) = 0. Now, using the Zero Product Property, we can set each factor equal to zero and solve for x. This gives us x = 0 and x = 5.

Answer:  The correct options are

(B) [tex]x=\dfrac{11+\sqrt{61}}{2}.[/tex]

Step-by-step explanation:  We are given to select the values of x that are the roots of the following polynomial :

[tex]x^2-11x+15.[/tex]

The quadratic equation formed by the given polynomial will be

[tex]x^2-11x+15=0~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

we know that

the solution set of a quadratic equation [tex]ax^2+bx+c=0,~~a\neq 0[/tex] is given by

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}.[/tex]

From equation (i), we have

a = 1, b = -11  and  c = 15.

Therefore, the roots of equation (i) will be given by

[tex]x=\dfrac{-(-11)\pm\sqrt{(-11)^2-4\times1\times15}}{2\times1}\\\\\\\Rightarrow x=\dfrac{11\pm\sqrt{121-60}}{2}\\\\\\\Rightarrow x=\dfrac{11\pm\sqrt{61}}{2}.[/tex]

Explanation: Think of a clock if it rotates 90 degrees counter clockwise it would stop at the number 9. If it rotates 90 clockwise it would stop at 3, then rotate that hand clockwise by 90 degrees one more time it will stop at 6, then 9 at 270 degrees.

Answer:

sorry if im late but this is the answer:

Step-by-step explanation:

Yes, I think they are the same. One revolution is 360 degrees. A 180-degree clockwise rotation is the same as a 180-degree counterclockwise rotation. The sum of the measures is 360. So, moving in a clockwise direction for 270 degrees would end at the same place as moving 90 degrees in a counterclockwise direction.
