Consider the graph of Angle BAC below.

Suppose angle BAC is reflected over the y-axis. What are the coordinates of angles B’A’C’?

Answer:

x = 17

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

15^2 + x^2 = (sqrt(514))^2

225 + x^2 = 514

Subtract 225 from each side

225-225 + x^2 = 514-225

x^2 =289

Take the square root of each side

sqrt(x^2) = sqrt(289)

x = 17

Answer:

  A) b > 10

  B) none

  C) b ≤ 10

Step-by-step explanation:

For the purpose of this answer, we assume ABC is a triangle if and only if all angles and side lengths have measures greater than 0, and the sum of angles is exactly 180°.

The fact that B = 150° means A+C = 30°. That is, 0 < A < 30°. Taking the sine of A, we have ...

  0 < sin(A) < 1/2

The Law of Sines tells us ...

  sin(A)/a = sin(B)/b

  sin(A) = a·sin(B)/b = 10·(1/2)/b = 5/b

Substituting this into the inequality for sin(A), we get ...

  0 < 5/b < 1/2

  0 < 10 < b . . . . . multiply by 2b (which is > 0)

In order to form a triangle, the value of b must be greater than 10. In that case, there will always be only one value for A:

  A = arcsin(5/b) . .  . . b > 10

__

For b = 10, the "triangle" is a straight line, a disallowed condition. That is A will have no allowed value.

For b < 10, A > 30°, which forces C < 0°. This is also a disallowed condition. So we can say ...

  b ≤ 10, A has no allowed value

_____

The attached diagram shows triangle ABC. Point A can be anywhere on ray BA. As segment c gets longer, angle C increases from near 0 to near 30°. At the same time, angle A decreases from near 30° to near 0°. When b=10, c=0, and the figure is not a triangle. Nor is it a triangle for b < 10.

Answer:

19

Step-by-step explanation:

79, 27, 24, 11, 14, 11​

rearrange the order

from lowest to highest

11, 11, 14, 24, 27, 79

Find the middle.

It is between 14 and 24

Take the average.

Average here = median = (14 + 24)/2 = 38/2 = 19

Final answer:

The median of the data set (79, 27, 24, 11, 14, 11) is found by first arranging the numbers in ascending order, and then taking the average of the two middle numbers, which yields a median of 19.

Explanation:

The median is the middle value of an ordered data set. To find the median, we first need to arrange the numbers in ascending order. The set of numbers given are 79, 27, 24, 11, 14, 11. Arranged in order they are 11, 11, 14, 24, 27, 79.

Since there are 6 values (an even number), we take the average of the two middle numbers. In this case, the two middle numbers are 14 and 24. Hence, we calculate the median as follows:

(14 + 24) / 2 = 38 / 2 = 19.

Therefore, the median of this data set is 19.

The correct fraction of the nachos that Jack and Connor ate together is [tex]\(\frac{1}{2}\)[/tex].

To determine the fraction of the nachos that Jack and Connor ate together, we need to add the fractions of the nachos each one ate.

Jack ate [tex]\(\frac{1}{3}\)[/tex] of the nachos. Connor ate [tex]\(\frac{1}{6}\)[/tex] of the nachos.

To add these two fractions, we need a common denominator. The least common multiple (LCM) of 3 and 6 is 6. So, we convert [tex]\(\frac{1}{3}\)[/tex] to a fraction with a denominator of 6 by multiplying both the numerator and the denominator by 2, which gives us [tex]\(\frac{2}{6}\)[/tex].

Now, we can add the two fractions:

[tex]\[\frac{2}{6} + \frac{1}{6} = \frac{3}{6}\][/tex]

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

[tex]\[\frac{3}{6} = \frac{1}{2}\][/tex]

Therefore, together, Jack and Connor ate [tex]\(\frac{1}{2}\)[/tex] of the nachos.

Answer:

Scale

I small square= 1 unit

For 4,700; 2,000; 3,400; 1,650; 2,800

I small square=100 unit

Step-by-step explanation:

We choose a scale such that all the points can be plotted on the graph.

For 70, 35, 55, 10, 43, 25, 80

the range of data is from 10 to 80

so if we choose I small square= 1 unit, we will be able to plot all the points on the graph.

For 4,700; 2,000; 3,400; 1,650; 2,800

the range of data is from 1600 to 4700

If we choose I small square=100 unit, we will be able to plot all the points on the graph with 1650 plotted in the middle of a small square.

Answer:

530.7?

Step-by-step explanation:

Answer: 530.7m

Step-by-step explanation:

The formula for the area of a circle is [tex]A=\pi r^2[/tex]

From the picture we can see that the diameter of the circle is 26m

The r, or radius of the circle is just half the diameter, thus the radius is 13m

Now that we have all the values of the variables, we can solve for A

Plug in 3.14 for π and 13 for r and solve

[tex]A=(3.14)(13)^2[/tex]

[tex]A=(3.14)(169)[/tex]

[tex]A=530.66m[/tex]

Answer:

The answer length is 10 and the width is 8 or the other way around.

Step-by-step explanation: The garden has a area of 80 square feet and since 10 has 2 more than 8 that the answer.

Final answer:

To find the length and width of the garden, set up the equation for the area of a rectangle: width times (width + 2) equals 80. Solving this gives us the width as 8 feet and the length as 10 feet.

Explanation:

The question asks us to find the length and width of a rectangular garden given that its area is 80 square feet and the length is 2 feet more than the width. We can represent the width with the variable w and then express the length as w + 2. To find the dimensions, we write the equation for the area of a rectangle (length × width):

w × (w + 2) = 80

Solving this quadratic equation gives:

w² + 2w - 80 = 0

Factoring the quadratic equation gives:

(w + 10) × (w - 8) = 0

Therefore, the width w could be 8 or -10. Since a negative width doesn't make sense for a garden, we take w = 8 feet as the width. Consequently, the length is w + 2 = 10 feet.

The dimensions of the garden are 8 feet by 10 feet or vice versa.

Answer:

x = -9.5

y = -2.5

Step-by-step explanation:

to evaluate this linear system of equation, we would say that

let

x = 3y - 2................................................ equation 1

x= -7y + 8.............................................. equation 2

substitute equation 2 into equation 1

3y -2 = 7y + 8

collect the like terms

3y -2 -8= 7y

-10 = 7y -3y

-10 = 4y

divide both sides by 4

-10/4 = 4y/4

-2.5 = y

y = -2.5

put the value value of y into equation 1

x = 3y - 2................................................ equation 1

x = 3(-2.5)  -2

x = -75 - 2

x = -9.5

To estimate the difference 7/8 - 6/11, replace each fraction with 1 or 1/2 based on their proximity to 1 or 1/2. The estimated difference is 1/2.

To estimate the difference 7/8 - 6/11, we need to replace each fraction with either 0, 1/2, or 1. Let's find the estimate for each fraction:

7/8 is closer to 1 because the numerator is close to the denominator. So, we replace it with 1.

6/11 is closer to 1/2 because the numerator is half of the denominator. So, we replace it with 1/2.

Now, we can subtract the estimated values: 1 - 1/2 = 1/2.

Therefore, the estimated difference is 1/2.
