The angles in the circle is as follows:

m∠1 = 25 degrees

m∠2 = 12.5 degrees

The angle subtended by an arc of a circle at its centre is twice the angle it subtends anywhere on the circle's circumference.

The measure of an arc is the measure of its central angle. Therefore,

m∠1 = 360 - 160 - 175

m∠1 = 200 - 175

m∠1 = 25 degrees

Therefore, let's find the other angle m∠2.

m∠2 = m∠1 / 2

m∠2 = 25 / 2

m∠2 = 12.5 degrees

Answer:

A

Step-by-step explanation:

The exact answer is ~1.46

The amount paid for the bananas is $1.46.

Option B is the correct answer.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Cost of bananas per pound = $0.39

Cost of 3(3/4) pounds of bananas.

3(3/4) = 15/4

1 pound = 0.39

Multiply 15/4 on both sides.

15/4 pounds = 15/4 x 0.39

3(3/4) pounds = $1.46

Thus,

The cost for 3(3/4) pounds of banana is $1.46.

In a case whereby In 1950, a U.S. population model was y = 151. (1.013)^t-1950 million people, where t is the year, the model predict the U.S. population would be 288 million in the year 2000.

Population models are mechanical theories that link alterations in population structure and density to responses at the individual level (life history features in eco-evolutionary theory or vital rates in demographic theory).

The model was given as y=151x(1.013)^t-1950

where the future time t = 2000

Then we can substitute the given year 2000 as the value of 't'

then we will have y=[151x(1.013)^(2000-1950)] = 288 million

The predicted number of employed graphic designers in 2023 can be calculated by applying the annual growth rate of 9% to the number of designers in 2012. Based on this calculation, it is estimated that there will be approximately 35,889 graphic designers employed in 2023.

1. Determine the initial number of graphic designers in 2012: The question states that there were 23,900 designs in the industry in 2012.

2. Calculate the annual growth rate: The question mentions that the graphic design industry has an annual growth rate of 9%. This growth rate represents an increase of 9% each year.

3. Calculate the growth in the number of graphic designers from 2012 to 2023: To find the growth in the number of graphic designers, multiply the initial number of designers (23,900) by the growth rate (9%) for each year. Repeat this process for each year from 2012 to 2023.

4. Add the growth in the number of designers to the initial number of designers: Sum up the growth in the number of designers for each year and add it to the initial number of designers in 2012.

5. Calculate the predicted number of employed graphic designers in 2023: The sum obtained in step 4 represents the estimated number of graphic designers employed in 2023.

Answer:

Quadrilateral: 20.5 units

Triangle: 8.6 units

Step-by-step explanation:

Quadrilateral:
We can use the following formula to find the perimeter of a quadrilateral.

Perimeter = AB + BC + CD + DA

where AB, BC, CD, and DA are the lengths of the four sides of the quadrilateral.

In your case, the coordinates of the vertices of the quadrilateral are A(-3,-1), B(-3,3), C(2,3), and D(4,-1).

Using the distance formula, we can find the lengths of the four sides of the quadrilateral as follows:

\(AB = \sqrt{(-3 - (-3))^2 + ((-1) - 3)^2} = \sqrt{16} = 4\)

\(BC = \sqrt{(-3 - 2)^2 + ((3) - 3)^2} = \sqrt{25}= 5\)

\(CD = \sqrt{(2 - 4)^2 + ((3) - (-1))^2} = \sqrt{4+16} = 2\sqrt{5}\)

\(DA = \sqrt{(4 - (-3))^2 + ((-1) - 1)^2} = \sqrt{49} =7\)

Therefore, the perimeter of the quadrilateral is:

Perimeter = AB + BC + CD + DA

= \(4+5+2\sqrt5+7=20.5\) units

Triangle

The perimeter of a triangle is the total length of all three sides of the triangle. To find the perimeter of a triangle, we can use the following formula:

Perimeter = AB + BC + CA

where AB, BC, and CA are the lengths of the three sides of the triangle.

In your case, the coordinates of the vertices of the triangle are

E(-4,1), F(-2,3), and G(-2,4). Using the distance formula, we can find the lengths of the three sides of the triangle as follows:

\(EF = \sqrt{(-4 - (-2))^2 + ((1) - (3))^2} = 2\sqrt{2}\)

\(FG = \sqrt{(-2 - (-2))^2 + ((3) - (4))^2} = 1\)

\(EG = \sqrt{(-4 - (-2))^2 + ((1) - (4))^2} = \sqrt{4 + 9} = \sqrt{13}\)

Therefore, the perimeter of the triangle is:

Perimeter = EF + FG + EG

= 4 + 1 + \(\sqrt{13}\)

=8.6 units

Therefore, the perimeter of the quadrilateral is 20.5 units and the perimeter of the triangle is 8.6 units

The central angle of Bathing = 108 degrees.

In the given pie chart,

Since we know,

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle possesses rotational symmetry around the center.

The whole circle is 360 degrees

which represents 100%.

It is given that,

Bathing = 30%

So have need to find 30% of 360 degrees.

Therefore,

Bathing = (30/100)x360

            =  (30/10) x 36

            = 3x36

            = 108

Binh reveived 40 votes

It asked for ratio of Binh’s votes to Davina’s

so the ratio is first Binh's 40 to Davina's 50     that's 40 to 50

It want it in simplest form so you find the greatest common factor of 40 and 50 which is 10.

40/10 and 50/10 is 4 to 5

So the answer is 4:5(The ":"  means  "to")

The ratio of Binh’s votes to Davina’s votes is 4:5

Answer:

20° and 70°

Step-by-step explanation:

complimentary angle sum to 90°

let x be the compliment then the angle is 3x + 10 , so

x + 3x + 10 = 90 , that is

4x + 10 = 90 ( subtract 10 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20

3x + 10 = 3(20) + 10 = 60 + 10 = 70

the 2 angle measures are 20° and 70°

The equation that can be used to calculate the concrete weight, w = k·v, and the 740 pounds weight of 5 cubic feet concrete, gives the value of k (which is the density of the concrete) as 148 lb/ft³

The density of a material is the ratio of the mass of the material to its volume.

(b) The weight, w of the concrete is directly proportional to the volume, v of the concrete

The weight of 5 cubic feet = 740 pounds

The equation that can be used to calculate the weight of a given volume of concrete is; w ∝ v

Where;

k = The constant of proportionality

Which gives;

\(k = \dfrac{w}{v}\)

In a proportional relationship between two variables, one variable is a constant multiple of the other such that the ratio of the two variables is a constant, k, which can be found using the value for the data point in the question;

When the weight is 740 pounds, the volume is 5 cubic feet, which gives;
