The area sector of a circle with radius 7 is 9 π/. What is the radian measure θ, the central angle of the sector? Express your answer in exact form.

Answers

Answer 1

Answer:

Radian angle = 1.154

Central angle = 66.123°

Step-by-step explanation:

Area of Sector, A

A = 1/2 * r² * θ ; θ measured in radian

A = 9 π

r = 7

9 π = 1/2 * 7² * θ

9 π = 24.5θ

θ = 9 π / 24.5

θ = 1.154 radian

1 radian = 57.296°

1.154 radian = (57.296 * 1.154)

1.154 radian = 66.123°

A square box lid has an area of 50 square inches. Which is the best estimate of the length of one side?

Answers

Answer: 7.1 inches

Step-by-step explanation:

The area of a square is simply the square of one of its length. Therefore since we are informed that the area of the square box is given as 50 inches².

Then the best estimate of the length of one side will be the square root of 50 which will be:

= ✓50

= 7.1 inches approximately

Mr. Dieter wants to tile the family room in his basement. He has selected a pattern of square tiles that measure 9 inches by 9 inches each. The shape of the floor to be tiled is shown below. a. What is the area of the family room in square feet? b. How many of the 9 inch by 9 inch tiles will it take to cover the floor? (NOTE: You will need to convert the area in Part a from square feet to square inches.) c. If the tile is sold only in boxes of 12 tiles per box, how many boxes will Mr. Dieter have to buy to tile the family room?

Answers

Answer:

146 ft²

21.6 tiles

1.8 boxes

Step-by-step explanation:

Please find attached an image of the family room used in answering this question

the family room has the following shapes : 2 triangles and one rectangle

the area of the family room can be determined by calculating the area of each of the shape and adding the 3 areas together

area of a rectangle = length x breadth

16 x 7 = 112 ft²

Area of a triangle = 1/2 x base x height

Area of the smaller triangle = (1/2) x 4 x 3 = 6 ft²

Area of the bigger triangle = (1/2) x 8 x 7 = 28 ft²

Sum of the areas = 112 + 6 + 28 = 146 ft²

b.

1. First convert the area of the room to inches

1 ft = 12 in

146 x 12 = 1752 in²

2. the next step is to determine the area of the tile

area of a square = length²

9² = 81 in²

3. Divide the area of the room by the area of the tile

1752 / 81 = 21.6 tiles

c. total number of boxes that would be bought = 21.6 /12 = 1.8 boxes

It is translated left 2 units.
It is translated right 2 units.
It is compressed vertically by a factor of 2.
It is compressed horizontally by a factor of 2.

Answers

Answer:

For this transition of equations, the graph of g(x) will be translated left 2 units with respect to the graph of f(x), so your answer choice will be A.

Step-by-step explanation:

In this equation, g(x) is changed by adding 2 and closing part of the equation in parenthases, this results in the translation 2 units left, which can be proven by a graph and my answer.

How do you find the value of x in the triangle?

To find the value of x in a triangle, you need to subtract the sum of the two angles from 180 degrees. Know that the sum of all the angles of a triangle will always equals 180 degrees. Then write down the difference of subtracting the sum of the two angles from 180 degrees and that would equal the value of x.

Find the radius of a circle with an area of 1017.36 in?, Use 3.14 for pi​

Answers

area of a circle = πr², where r = the radius of the circle

We can rearrange the formula to solve for r:

[tex]r=\sqrt{\frac{\mathrm{area}}{\pi}}.[/tex]

Given an area of 1017.36 in² and using 3.14 for our value for π, the radius of our circle would be:

[tex]r=\sqrt{\frac{\mathrm{area}}{\pi}} = \sqrt{\frac{\textrm{1017.36 }\mathrm{in^2}}{3.14}} \\ r = 18 \text{ } \mathrm{in^2}.[/tex]

Rob's first four test scores are 80, 85, 100 and 85. What does he have to score on the last test in order to have a test average of 90?

Answers

Answer:

100

Step-by-step explanation:

85 +80+100+85+x(the unknown),/the number of numbers ie 5

350+x/5=90

350+x=90 * 5

350+x=450

x=450-350

x=100

The score on the last test in order to have a test average of 90 is 100.

Given that, Rob's first four test scores are 80, 85, 100 and 85.

We need to find the score on the last test in order to have a test average of 90.

What is an average?

By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.

Let the score on the last test be x.

Now, average=(80+85+100+85+x)/5 =90

⇒350+x=450

⇒x=100

Therefore, the score on the last test in order to have a test average of 90 is 100.

Answers

Answer:

0.9958

Step-by-step explanation:

P(being correct) = 1/4 = 0.25

Hence, p = 0.25

n = 19

P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

However, to save computation time, we could use a calculator :

Using a calculator,

P(x ≥ 1) = 0.99577

P(x ≥ 1) = 0.9958
