Answer:32

Step-by-step explanation:

If Quadrilateral BEAR is inscribed in circle o,then the measure of R is 106 degrees.

A quadrilateral is a four-sided polygon, having four edges and four corners.

The sum of angles of a quadrilateral is 360 degrees.

Angle E is 74 degrees.

Angle A is 92 degrees.

We need to find the angle R.

The angle at B is 90 degrees as it makes right angled.

∠E+∠A+∠R+∠B=360

74+92+∠R+90=360

256+∠R=360

Subtract 256 on both the sides

∠R=360-256

∠R=106 degrees.

Hence, the measure of R is 106 degrees.

Answer:

$64.80

Step-by-step explanation:

First, calculate the sales tax

Convert 8% into a decimal

8/100=0.08

Multiply the decimal by the cost of the game

60*0.08=4.8

$4.80 is just the tax, we have to find the total cost

Add the tax and the cost of the game

60+4.80=64.80

So, the total cost is $64.80

Answer:

D. 21 ft

Step-by-step explanation:

We need to use Power of Points, which basically says that for intersecting chords in a circle (see attachment), a * b = c * d.

Here, we can say that a = x, b = 6, c = 7, and d = 18. Then, we have the equation:

ab = cd

x * 6 = 7 * 18

6x = 126

x = 21

Thus, x is 21 ft.

Hope this helps!

Answer:

Last one: 21 ft

Step-by-step explanation:

x × 6 = 7 × 18

x = (7 × 18)/6

x = 21 ft

Answer:

The answer is C. $510.

I have just took the test.

Option C is correct, Each person receives an amount of $510.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

To calculate the bonus, we need to find the four middle monthly sales values.

Arranging the sales values in ascending order, we get:

17.1, 18.4, 18.9, 21.6, 26.1, 29.2

The four middle values are: 18.4, 18.9, 21.6, and 26.1.

Average= (18.4 + 18.9 + 21.6 + 26.1) / 4 = 21.25

Taking 12% of this value gives:

0.12 x 21.25 = 2.55

The bonus amount to be split among the five salespeople is $2.55. Therefore, each salesperson will receive:

2.55 / 5 = 0.51

Therefore, each salesperson will receive $1 as a bonus.

Hence, Option C is correct, Each person receives an amount of $510.

Step-by-step explanation:

i think this because she only surveyed a very small population of the seventh graders and the more data the more accurate your prediction will be. Hope that helps.

A)The number of students in the seventh grade who would be expected to prefer math to science are: 128

B) The true statement about the inference is (c) Yes, this is a valid inference because he took a random sample of the neighborhood

A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.

here, we have,

A) Given that, the total number of students in seventh grade are: 150 students.

Now he took a sample of 25 students and find that the 85% of the sample prefers math to science.

This means that out of the sample the number of students who prefer math to science is:

= 85 / 100 x 25

= 21.25

Now, out of the total seventh graders the number of students who prefer math to science is:

21.25 x 150 / 25 = 127.5 ≈ 128

B) From the question, we understand that:

Mark draws a random sample of 20 addresses from all 80 of the neighborhood addresses.

The above selection is a random sampling technique

Answer: D

Step-by-step explanation: To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.

Dividing the number of sides by the area of one of the composite figure's sides. and adding the areas of all the forms or faces that comprise the composite figure helps to find the area of a two-dimensional composite figure. Options A and B are correct.

The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.

The area of a two-dimensional composite figure or the surface area of a three-dimensional composite figure may be calculated by;

Dividing the number of sides by the area of one of the composite figure's sides. and add the areas of all the forms or faces that comprise the composite figure.

Answer:

short allele is recessive, tall allele is dominant

Answer:

Step-by-step explanation:

While the h portion of that absolute value represents the side to side movement, the k represents the up and down.  The pointy part of the graph (the vertex) is lowered from its position at y = 0 to y = -2.5

So k = -2.5

The correct value of k is k = -2.5. Hence, option a is correct.

To find the value of k for the function f(x) = |x - h| + k, you can use one of the given points, as all points lie on the graph of the function.

Let's use the point (1, -2.5) with coordinates (x, y).

Plug these coordinates into the function:

-2.5 = |1 - h| + k

Now, you need to find k:

-2.5 = |1 - h| + k

To isolate k, you can solve for k:

k = -2.5 - |1 - h|

Now, let's check which option fits this equation based on the given points:

For h = 1 (as in the point (1, -2.5)), you get:

k = -2.5 - |1 - 1| = -2.5 - 0 = -2.5

So, the correct value of k is k = -2.5.

Final answer:

The volume of the triangular prism is found by multiplying the area of the base (25 sq cm) by the height (6 cm), which results in a volume of 150 cubic centimeters.

Explanation:

The question asks for the calculation of the volume of a triangular prism. The formula to find the volume (V) of a triangular prism is V = base area × height. The base area of the prism is given as 25 sq cm, and the height is 6 cm. Therefore, the volume of the triangular prism is calculated as follows:

V = base area × height

V = 25 cm² × 6 cm

V = 150 cm³

Thus, the volume of the triangular prism is 150 cubic centimeters.

Answer:

  93,675

Step-by-step explanation:

We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.

The number of terms in the sequence (n) can be found from the formula for the n-th term:

  an = a1 +d(n -1)

  (an -an)/d +1 = n

  (252 -997)/(-5) +1 = n = 150

The sum of these terms is the average of the first and last terms, multiplied by the number of terms:

  S150 = (997 +252)/2·150 = 93,675

The sequence sum is 93,675.

y - b = ax² ( divide both sides by a )

[tex]\frac{y-b}{a}[/tex] = x² ( take the square root of both sides ), thus

So,

∠2+∠5

=90+90
