Answer:

The answer to your question is the height of the lamp is 18.2 ft

Step-by-step explanation:

Data

Street lamp shadow = 31.5 ft

Street sign height = 8 ft

Street sign shadow = 14 ft

Street lamp height = x

Process

1.- To find the height of the lamp use proportions. In this kind of problem, we do not look for the length, but the shadow.

Street lamp height/street lamp shadow = street sign height/street sign

                                                                                                         shadow

Substitution

                                             x / 31.5 = 8 / 14

Solve for x

                                            x = (31.5)(8) / 14

Simplification

                                            x = 254.4 / 14

Result

                                            x = 18.2 ft              

To find the length and height of the lamp, set up proportions using the shadow lengths and given values, then solve for the lamp height and length based on the information provided.

The length of the lamp:

Answer:

  232°

Step-by-step explanation:

There are a couple of ways to find the desired direction. Perhaps the most straightforward is to add up the coordinates of the travel vectors.

  30∠270° +50∠210° = 30(cos(270°), sin(270°)) +50(cos(210°), sin(210°))

  = (0, -30) +(-43.301, -25) = (-43.301, -55)

Then the angle from port is ...

  arctan(-55/-43.301) ≈ 231.79° . . . . . . . 3rd quadrant angle

The bearing of the ship from port is about 232°.

Comment on the problem statement

The term "knot" is conventionally used to indicate a measure of speed (nautical mile per hour), not distance. It is derived from the use of a knotted rope to estimate speed. Knots on the rope were typically 47 ft 3 inches apart. As a measure of distance 30 knots is about 1417.5 feet.

Answer:

Perimeter of the model is approximately 1 m.

Step-by-step explanation:

Given:

Scale factor = [tex]\frac{1}{32}[/tex]

Actual base length of the sailboat (b) = 8 m

Actual hypotenuse length of the sailboat (h) = 13 m

Using Pythagoras theorem, we can find the third side of the right angled sailboat. Let the third side be 'l' m. So,

[tex]h^2=b^2+l^2\\\\13^2=8^2+l^2\\\\l^2=169-64\\\\l=\sqrt{105}=10.25\ m[/tex]

Now, actual perimeter of the sailboat = Sum of all the 3 sides

Actual perimeter = 13 m + 8 m + 10.25 m = 31.25 m

Now, we know that,

Scale factor = Model dimensions ÷ Actual dimensions

So, in terms of perimeter,

Scale factor = Model perimeter ÷ Actual perimeter

[tex]\frac{1}{32}=\frac{Model\ perimeter}{31.25}\\\\Model\ perimeter=\frac{31.25}{32}=0.97\approx1\ m[/tex]

So, perimeter of the model is approximately 1 m.

Step-by-step explanation:

The integral is the area under the curve.  When the curve is above the x-axis, the area is positive.  When the curve is below the x-axis, the area is negative.  The integral equals 0, so we want to find the value of b such that the area of the quarter circle is canceled out by the area of the triangle.

Area of the quarter circle is:

A = π/4 r²

A = 9/4 π

Area of the triangle is:

A = ½ bh

9/4 π = ½ (b − 3) (b − 3)

9/2 π = (b − 3)²

b − 3 = 3√(π/2)

b = 3 + 3√(π/2)

b = 6.760

Answer:

Alex can do the job in 60 days alone.

Step-by-step explanation:

Alex and Brandon working together, they can finish the job of cleaning the school in 15 hours. Brandon alone in 20 hours can finish the job.

So, Brandon can complete [tex]\frac{1}{20}[/tex] part of the job in one hour.

Let, Alex alone can finish the same job in x hours.

So, Alex can complete [tex]\frac{1}{x}[/tex] part of the job in one hour.

So, working together they do [tex](\frac{1}{20} + \frac{1}{x}) = \frac{x + 20}{20x}[/tex] part of the whole job in one hour.

Hence, from the conditions given we can write

[tex]\frac{x + 20}{20x} = \frac{1}{15}[/tex]

⇒ 15x + 300 = 20x

⇒ 5x = 300

⇒ x = 60 days.

Therefore, Alex can do the job in 60 days alone. (Answer)

Answer:

( 1, 7.5 )

Step-by-step explanation:

First I found the midpoint of the G and H coordinates. Then I found the midpoint of that new coordinate and G.

The coordinate of point J is given by the section formula with ratio 1: 3 is (1, 7.5).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of line, etc.

Segment GH has endpoints at G(-2,9) and H(10,3). Point J lies on GH between G and H such that GJ: GH is 1: 3.

Let the coordinate of the J be (x, y).

We know that the section formula is given as

[tex]\rm (x, y) = ( \dfrac{m_1x_2 + m_2x_1}{m_1 + m_2}, \dfrac{m_1y_2 + m_2y_1}{m_1 + m_2})\\\\(x, y) = ( \dfrac{1*10+3(-2)}{1+3}, \dfrac{1*3+ 3*9}{1+3})\\\\(x, y) = ( \dfrac{4}{4}, \dfrac{30}{4})\\\\(x, y) = (1, 7.5)[/tex]

After calculating the initial velocity with which the ball was thrown upwards, the time taken for the ball to reach its peak and fall back to earth was calculated to be approximately 38 seconds.

In order to find out how long the ball will be in the air, we are essentially dealing with an example of free fall in Physics. When the ball reaches its maximum height, its velocity will be zero and it will have spent a certain amount of time t to reach there. But the total time it will be in the air is twice this amount, as it will take the same amount of time to go up and come back down.

Using the second equation of motion, v = u + gt (where v = final velocity, u = initial velocity, g = acceleration due to gravity and t = time), when the ball reaches maximum height, its final velocity (v) is zero. If we rearrange this equation, we get t = (v - u) / -g.

As the problem doesn't state the initial velocity with which the ball is thrown upward, we need to find it first. We can do this by applying the equation of motion: v² = u² + 2gs, where s = displacement. If we set v = 0 at maximum height, the equation becomes u = √(2gs). Given s = 178 m and g = 9.8 m/s², we find u ≈ 186.26 m/s. Substituting these values into our time equation, we get t ≈ 19 seconds for the time to reach maximum height. As mentioned, the ball will take the same time to fall back, hence the total time in air will be around 38 seconds.

Answer:

$1510.32 (Select option closest to this)

Step-by-step explanation:

Given:

-  Siding material cost = $18.50 per square yard

- installation cost = $12.40 per square yard

- width of one side = 22 ft

- height of one side = 10 ft

Find:

- How much should you charge to put siding on the ends of the house

Solution:

- Assuming the the cost of material is also borne by you. Summing the rate of material and installation for both sides for you per square yard:

Total rate for both side = 2*($18.50 per square yard + $12.40 per square yard

 Total rate for both side = $ 61.8 per square yard

- Area covered by a side is:

  Area covered = 10 * 22 = 220 ft^2 * (yard^2 / 9 ft^2) = 24.44 yard^2

- Total amount you will be charging is:

   Total amount = Total rate for both side * Area covered

   Total amount = $ 61.8 per square yard * 24.44 yard^2 = $1510.32

Answer:

The average radius of sun is approximately 9.95 times the average radius of Jupiter.                                

Step-by-step explanation:

We are given the following in the question:

Average radius of Jupiter =

[tex]4.34\times 10^{4}\text{ miles}[/tex]

Average radius of the sun =

[tex]4.32\times 10^{5}[/tex]

Relation between average radius of sun and average radius of Jupiter =

[tex]\displaystyle\frac{\text{Average radius of Sun}}{\text{Average radius of Jupiter}}\\\\= \frac{4.32\times 10^{5}}{4.34\times 10^{4}}\\\\\displaystyle\frac{\text{Average radius of Sun}}{\text{Average radius of Jupiter}} = 9.953917\\\\\text{Average radius of Sun} \approx 9.95\times \text{(Average radius of Jupiter)}[/tex]

Thus, the average radius of sun is approximately 9.95 times the average radius of Jupiter.

To determine how many times greater the Sun's radius is compared to Jupiter, divide the Sun's radius (695,700 km) by Jupiter's radius (71,400 km), resulting in the Sun being approximately 9.75 times greater than Jupiter in size.

The question asks how many times greater the average radius of the Sun is compared to that of Jupiter. To find this, we will divide the Sun's radius by Jupiter's radius. The radius of Jupiter is given as 71,400 km, while the radius of the Sun is much larger at 695,700 km.

Calculating the ratio, we get:

Therefore, the average radius of the Sun is roughly 9.75 times greater than that of Jupiter.

Step-by-step explanation:

Regular polygons have the same number of lines of symmetry as they do sides.

Polygons with an even number of sides have a line of symmetry for each pair of opposite vertices, as well as a line of symmetry through midpoints of opposite sides.

Polygons with an odd number of sides have a line of symmetry for each vertex, passing through the midpoint of the opposite side.

A heptagon has 7 vertices, and therefore has 7 lines of symmetry.

Time required for the pendulum to swing from its position furthest to the right to its position furthest to the left: 1.25 seconds

Step-by-step explanation:

A pendulum is a system consisting of a rod/string connected to a mass which is left free to oscillate back and forth around its equilibrium position, straight vertical.

The period of a pendulum is the time the pendulum takes to complete one full oscillation, that means it is the time the pendulum takes to go from its furthest position on the left to the same position again. It is calculated as

[tex]T=2\pi \sqrt{\frac{L}{g}}[/tex]

where L is the length of the pendulum and g the acceleration of gravity.

The figure in this problem represents the position of the pendulum. We observe that the time it takes for the pendulum to do one complete oscillation is 2.5 seconds.

The time it takes for the pendulum to swing from its position furthest to the right to its position furthest to the left is half the period: therefore, it is

Answer:

Conclusion: The proportion of customers satisfied with the service they receive from the large electric utility company is different from 80%, the claim made by the CEO.

Step-by-step explanation:

To test the claim made by the CEO of a large electric utility company the newspaper must conduct a hypothesis test for one proportion.

Assumption:

The significance level (α) of the test can be assumed to be 5%.

Hypothesis:

[tex]H_{0}:[/tex] The proportion of customers satisfied with the service they receive is 0.80, i.e. [tex]p=0.80[/tex]

[tex]H_{a}:[/tex] The proportion of customers satisfied with the service they receive is different from 0.80, i.e. [tex]p\neq 0.80[/tex]

Decision Rule:

If the p-value of the test is less than the significance level (α) then the null hypothesis may be rejected. But if the p-value  is more than the significance level (α) then we cannot reject the null hypothesis.

Test Statistics:

As the sample size is large, i.e.n = 100 > 30, then according to the central limit theorem sampling distribution of sample proportion will follow the normal distribution.

The test statistic used is:

[tex]z=\frac{\hat p-p}{\frac{\sqrt{p(1-p)}} {n} }[/tex]

Given:

The p-value of the hypothesis test is computed to be 0.894.

That is:

[tex]p-value=0.894>\alpha =0.05[/tex]

This implies that we fail to reject the null hypothesis at 5% level of significance.

Conclusion:

The null hypothesis was failed to be rejected at 5% level of significance.

Thus, concluding that the proportion of customers satisfied with the service they receive from the large electric utility company is different from 80%, the claim made by the CEO.

Answer:

The bus left New York city at 5:10pm

Step-by-step explanation:

First, we need to calculate the total number of hours the bus used to travel from New York to Washington.

Total number of hours traveled

= 2 1/3hr + 1 3/4hr + 5/6hr

= 7/3+7/4+5/6

=28+21+10/12

=59/12

= 4 11/12hours

Converting 11/12hours to minutes we will have 11/12×60 = 55minutes

Therefore the bus traveled for 4hours 55minutes.

If the bus arrived in Washington at 10:05 pm and the bus left New York 4hours 55minutes ago, this means that the bus did left New York at (10.05-4.55)pm i.e 5:10pm

4hours past 10:05pm will be 6:05pm

55minutes past 6:05pm will be 5:10pm

This means that the bus left New York city at 5:10pm
