Find the measure of one exterior angle of the following polygon:
Nonagon

Answer: $0.12 per pound

Step-by-step explanation:

divide $360.00 by 3, then divide it by 1000, because 1000 lbs is 1 ton

Final answer:

To calculate the price per pound of dirt, divide the total cost of $360.00 by the total weight of 6000 pounds, resulting in a cost of $0.06 per pound.

Explanation:

The student asked how much it would cost per pound if 3 tons of dirt cost $360.00. First, it's essential to know how many pounds are in a ton. There are 2000 pounds in one ton. So for 3 tons, there would be 6000 pounds (3 tons x 2000 pounds/ton).

Next, to find the price per pound, you would divide the total cost by the total weight in pounds. That's $360.00 divided by 6000 pounds, which equals $0.06 per pound.

Therefore, the price per pound of dirt is $0.06.

The approximate measure of the angle formed by the top of the slide and the vertical support is approximately 21.8 degrees.

In trigonometry, the tangent function can help us find the angle in a right-angled triangle. The tangent of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the adjacent side. In this case, the side opposite the angle is the height of the slide (20 feet), and the adjacent side is the length of the slide (50 feet).

Now, we can use the tangent function to find the angle (θ):

tan(θ) = Opposite / Adjacent

tan(θ) = 20 feet / 50 feet

tan(θ) = 0.4

To find the value of θ, we can take the inverse tangent (also known as arctan or tan⁻¹) of 0.4:

θ ≈ arctan(0.4) ≈ 21.8 degrees

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Brett is paid $18.95 per hour.

For 0 to 40 hours a week,

For any hours over 40, Brett makes

= 1.5 ($18.95)

= $28.425/hour

In Week 1:  40 hours x $18.95/hour = $758

2 hours x $28.425/hour = 56.85

Week 2:  36 hours x $18.95/hour = 682.2

let's bear in mind that the cylinder and the cone both have the same volume of 112 cm³, and the same radius, but different heights.

[tex]\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} V=112\\ h=7 \end{cases}\implies 112=\pi r^2(7)\implies \cfrac{112}{7\pi }=r^2\implies \cfrac{16}{\pi }=r^2 \\\\\\ \sqrt{\cfrac{16}{\pi }}=r\implies \cfrac{\sqrt{16}}{\sqrt{\pi }}=r\implies \cfrac{4}{\sqrt{\pi }}=r \\\\[-0.35em] ~\dotfill[/tex]

[tex]\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}\qquad \qquad \begin{cases} r=\frac{4}{\sqrt{\pi }}\\ V=112 \end{cases}\implies 112=\cfrac{\pi \left( \frac{4}{\sqrt{\pi }} \right)^2(h)}{3} \\\\\\ 336=\pi \left( \cfrac{4^2}{(\sqrt{\pi })^2} \right)h\implies 336=\pi \cdot \cfrac{16h}{\pi }\implies 336=16h \\\\\\ \cfrac{336}{16}=h\implies \blacktriangleright 21=h \blacktriangleleft[/tex]

Calculate the radius of the cup using its volume and height. Determine the cone's height by applying the cup's height to the volume formula for a cone after elimination.

The volume of the cup:

The formula for the volume of a cylinder: V = πr²h.

The formula for the volume of a cone: V = (π/3)r²h.

(πr²h)cylinder = ((π/3)r²h)cone

Since the cone has the same radius as the cylindrical cup and given h = 7 cm

Finding the height of the cone by eliminating:

[tex]h_{cylinder}[/tex] = [tex]h_{cone}[/tex]×(1/3)

[tex]h_{cone}[/tex] = 3 × 7 = 21

Therefore, height of cone is 21 cm.

The employers pay their employees based on hourly rates, commission and salary.

Step-by-step explanation:

The employees get their pay based on hourly rates that can range from a minimum hourly rate of say $12 per hour to any maximum figure like $40 per hour.

The final salary is based on the numbers of hours worked multiplied by the hourly rate.

Secondly, the pays are also commission based. That is your base salary plus the commission.

The salary is typical in management positions. These are not hourly based but a lump sum pay.

So, the correct answers are : commission, hourly pay and salary.

Replace x in the equation with the x value from the ordered pair and see if the y value meets the inequality.

y ≤ 2(-9) -7

y ≤ -18 - 7

y ≤ -25

The y value in the ordered pair is 1, so replace y with 1 and see if the inequality is true:

1 ≤ -25

1 is a positive value and the equation equals a negative value, so this is not true, because 1 is greater than -25.

Answer:

Step-by-step explanation:

We have given:

√2x+3 - √x+1  = 1

First of all isolate the square root of the left hand side:

√2x+3 = √x+1 +1

Now take square on both sides.

(√2x+3)^2 = (√x+1 +1)^2

Open the R.H.S by squaring formula.

∴(a+b)^2 = a^2+2ab+b^2

2x+3 = (√x+1)^2 + 2(√x+1)(1)+(1)^2

2x+3 = x+1 +2√x+1 +1

2x+3 = x+2 +2√x+1

Combine the like terms:

2x-x+3-2 = 2√x+1

x+1 = 2√x+1

Take square on both sides

(x+1)^2 = (2√x+1)^2

x²+2x+1 = 4x+4

x²+2x-4x+1-4 = 0

x²-2x-3 = 0

Now solve the quadratic equation:

a = 1 , b= -2 , c = -3

x = -b+/-√b²-4ac/2a

x = -(-2)+/-√(-2)² - 4(1)(-3) / 2(1)

x = 2 +/- √4+12 / 2

x = 2+/- √16/2

x = 2+/- 4 /2

x = 2+4/2     , x = 2-4/2

x = 6/2      , x = -2/2

x = 3      , x = -1

The solutions we get is (3, -1).

6 adults and 11 children.

In order to solve this problem we going to use linear equations.

A group of 17 people went to the concert. There are adults and children in that group x + y = 17 where x are adults and y are children. That group pay $57.50 for tickets, if tickets cost $5.00 for adults and $2.50 for children, then 5.00x + 2.50y = 57.50.

x + y = 17 ---------->  y = 17 - x

Substituting the value of y in the equation 5.00x + 2.50y = 57.50:

5.00x + 2.50(17 - x) = 57.50 solving

x = 6

Substituting x = 6 in the equation x + y = 17

6 + y = 17 solving

y = 11

From a group of 17 people who went to the concert 6 are adults and 11 are children.

Answer:

Base of each triangular face = 4 inches

Height of each triangular face = 6 inches

Step-by-step explanation:

The length of each side of the square base is the base of each isosceles triangle forming the pyramid.

We know from our problem that the ratio of the height of each triangle to its base is 3:2, so [tex]\frac{height}{base} =\frac{3}{2}[/tex]. We also know that the base is a square with sides 4 inches long, since the bade of the square is the base of the isosceles triangle, [tex]base=4[/tex].

Replacing the value of the base in our proportion:

[tex]\frac{height}{base} =\frac{3}{2}[/tex]

[tex]\frac{height}{4} =\frac{3}{2}[/tex]

Multiply both sides by 4

[tex]\frac{height}{4}*4 =\frac{3}{2}*4[/tex]

[tex]height=\frac{3*4}{2}[/tex]

[tex]height=\frac{12}{2}[/tex]

[tex]height=6[/tex]

Answer:

s = 4

Step-by-step explanation:

Solve for s:

8 s - 10 = 34 - 3 s

Add 3 s to both sides:

8 s + 3 s - 10 = (3 s - 3 s) + 34

3 s - 3 s = 0:

8 s + 3 s - 10 = 34

8 s + 3 s = 11 s:

11 s - 10 = 34

Add 10 to both sides:

11 s + (10 - 10) = 10 + 34

10 - 10 = 0:

11 s = 34 + 10

34 + 10 = 44:

11 s = 44

Divide both sides of 11 s = 44 by 11:

(11 s)/11 = 44/11

11/11 = 1:

s = 44/11

The gcd of 44 and 11 is 11, so 44/11 = (11×4)/(11×1) = 11/11×4 = 4:

The flow rate is 2 quarts per minute. There are 4 quarts in a US gallon, so 2 quarts divide 4 quarts per US gallon = 0.5 gallons per minute There are 60 seconds in a minute, so the flow rate is 0.5 gallons per minute divide 60 seconds per minute = 0.0083 gallons per second

Converting 2 quarts per minute to gallons per second requires the use of two conversion factors. First, quarts are converted to gallons by dividing by 4. Then, minutes are converted to seconds by dividing by 60. After performing these steps, it is found that 2 quarts per minute is approximately equal to 0.00833 gallons per second.

The student is asking to convert a flow rate from quarts per minute to gallons per second. There are a few fundamental conversions you need to use to find the answer. Firstly, remember that 1 gallon (gal) is equivalent to 4 quarts (qt). So, to convert the quarts to gallons, divide the quarts by 4. Secondly, there are 60 seconds in a minute; thus, you have to convert the minutes to seconds by dividing by 60.

Let's go step-by-step:

Therefore, 2 quarts per minute is approximately equal to 0.00833 gallons per second.
