A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?

Answers

Answer 1

Answer:

Building to the left is taller.

Step-by-step explanation:

Kindly refer to the attached diagram for the given dimensions.

[tex]\triangle ABR, \triangle PQR[/tex]

AB and PQ be the two buildings.

The car be parked at point R.

[tex]\angle ARB = 50^\circ\ and \\\angle PRQ = 40^\circ[/tex]

Distance of R from building bases:

BR = 49 m

QR = 56 m

Let us use tangent in [tex]\triangle PQR:[/tex]

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan40 = \dfrac{h_1}{56}\\\Rightarrow h_1 = 56 \times 0.839 \\\Rightarrow h_1 \approx 47\ m[/tex]

Let us use tangent in [tex]\triangle PQR:[/tex]

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan50 = \dfrac{h_2}{49}\\\Rightarrow h_2 = 49 \times 1.19 \\\Rightarrow h_2 \approx 58.4\ m[/tex]

So, building to the left is taller.

how many times does 1/4 go into 9/16

Answers

Answer as a fraction = 9/4

Answer in decimal form = 2.25

================================================

Explanation:

1/4 = 4/16 after multiplying top and bottom by 4

We have some number x such that

(4/16)x = 9/16

we can multiply both sides by 16 to clear out the fractions, getting 4x = 9

Then we divide both sides by 4 to get x = 9/4 = 2.25

Is (x-4)

Suppose you walk down a school hallway at a rate of 5 ft/s, and you reach your destination in 20 seconds. How do you write a function that models this situation, and how do you determine the domain?

Answers

Answer:

Step-by-step explanation:

Let's write a equation.

5 ft = 20 seconds

(five feet is reachable in 20 seconds)

Divide both sides by 5.

5/5=1

20/5=4

1 ft = 4 seconds

Let's say the destination is d and f is foot.

d = 4f

the mean of monthly salaries of 15 worker of a company is 2930 .A new worker with monthly salary 3138 join the company.Find the new mean monthly salary of 16 workers​

Answers

Answer: 2943

=======================================================

Explanation:

S = sum of the salaries of the first 15 employees

S/15 = mean of the 15 salaries

S/15 = 2930

S = 15*2930

S = 43950

The 15 workers salaries add to 43950.

If we add on a new 16th salary of 3138, then the sum bumps up to

S+3138 = 43950+3138 = 47088

This is the sum of the 16 workers salaries. Divide this over 16 to get the new average

47088/16 = 2943

The new mean is 2943

It is larger than the old mean because the 16th salary is larger than the mean. Effectively this new salary pulls on the mean to make it larger. With very distant outliers, the mean is pulled a lot which often causes problems. So this is why the median is a better measure of center in those situations. Either that measure of center, or using a trimmed mean works as well.

A wheel has a diameter of 70 cm and completes a revolution in 0.25 seconds at top speed
A) determine the angular velocity, w, in radians per second
B) how far does the the wheel in one minute

Answers

Answer:

8π radians/second527.8 meters

Step-by-step explanation:

A) The angular velocity is the ratio of angular distance to time:

  ω = 1 revolution / (0.25 s) = (2π radians)/(0.25 s)

  ω = 8π radians/second

__

B) The arc length is ...

  s = rθ = rωt

  s = (35 cm)(8π rad/s)(60 s) = 16,800π cm

  s ≈ 52779 cm = 527.79 m

The wheel travels about 527.8 meters in one minute.

A room with poor air quality has a particle concentration of 80 units. ​A fan removes 50% of the remaining particles each hour. What is the ​particle concentration, in these same units, in the room after 2 hours? ​​

Answers

Answer:

20 units

Step-by-step explanation:

Initial particle concentration = 80 units

Particles removed each hour = 50% of the remaining particles

To find:

Particle concentration after 2 hours = ?

Solution:

Particles removed in 1 hour = 50% of remaining particles

i.e. Particles removed in 1 hour = 50% of initial concentration

Particles removed in 1 hour = 50% of 80 = 40

Particles removed in next 1 hour = 50% of remaining particles

i.e. Particles removed in next 1 hour = 50% of concentration after 1 hour

Particles removed in next 1 hour = 50% of 40 = 20

Total particles concentration removed in 2 hours = 40 + 20 = 60 units

Therefore, particle concentration after 2 hours = Initial concentration - Total particle concentration removed in 2 hours

= 80 - 60 = 20 units

The width of a rectangle measures (3.1s-1.6)(3.1s−1.6) centimeters, and its length measures (7.2s-4.6)(7.2s−4.6) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle? A. −6.2+10.3s B. −12.4+20.6s C. 1.5s+2.6 D. 5.2+3s

Answers

Answer:

B.  -12.4 + 20.6s.

Step-by-step explanation:

Perimeter = 2*length + 2 * width

= 2(3.1s - 1.6) + 2(7.2s - 4.6)

= 6.2s + 14.4s - 3.2 - 9.2

= 20.6s - 12.4

= -12.4 + 20.6s.

[tex]\boxed{-12+20.6s}[/tex]

To find the perimeter of a shape, we add length + width + length + width (or length * 2 + width *2). So we would multiply the width, (3.1s - 1.6), and the length, (7.2s - 4.6), by 2, and then add them together to find the perimeter.

2(3.1s - 1.6) + 2(7.2s - 4.6)

This is equal to:

6.2s + 14.4s - 3.2 - 9.2

Simplified, this is equal to:

20.6s - 12.4

(We have to switch it around, but this answer is equal to option b.)

-12.4 + 20.6s

Tip: To simplify an equation, you add like terms. Like terms are numbers that have the same variables or exponents; for example, -4 and 3 are like terms, as well as 5^2 and 8^2. (Keep in mind, the variables and/or exponents have to be the same if you combine the like terms. Numbers with different variables and exponents can never be combined!)

For a sale, a store decreases its prices on all items by 25%. An item that costs $120 before the sale now costs $120 - 0,25($120). Use the distributive property to write an equivalent expression for the items cost now

Answers

Answer:

[tex]Cost = \$120 * 1 - \$120 * 0.25[/tex]

Step-by-step explanation:

Given

[tex]Cost = \$120 - 0.25(\$120)[/tex]

Required

Solve using distributive property

[tex]Cost = \$120 - 0.25(\$120)[/tex]

[tex]\$120[/tex] can be rewritten as [tex]1(\$120)[/tex]

So:

[tex]Cost = 1(\$120) - 0.25(\$120)[/tex]

Factorize:

[tex]Cost = \$120(1 - 0.25)[/tex]

Now, we can apply distributive property on the expression;

[tex]Cost = \$120 * 1 - \$120 * 0.25[/tex]

Hence, the above is an equivalent expression.

Solving further, we have

[tex]Cost = \$120 - \$30[/tex]

[tex]Cost = \$90[/tex]

Please help! I have very limited time to answer, but I am really stumped!

Answers

Answer:

A

Step-by-step explanation:

So we have the function:

[tex]f(x)=y=\sqrt[3]{x-2}+8[/tex]

To find the inverse of the function, we can flip x and y and then solve for y. Therefore:

[tex]x=\sqrt[3]{y-2}+8[/tex]

Solve for y to find our inverse.

Subtract 8 from both sides:

[tex]x-8=\sqrt[3]{y-2}[/tex]

Cube each side. The right cancels:

[tex](x-8)^3=y-2[/tex]

Add 2 to both sides:

[tex]y=(x-8)^3+2[/tex]

Therefore, our inverse is:

[tex]f^{-1}(x)=(x-8)^3+2[/tex]

Explain how you could use the construction tool or a compass and straightedge to create a line segment that is twice as long as A and B

Answers

Step 1) Plot point C that is not on segment ABStep 2) Draw a straight line through point C (convention usually has this line parallel to AB but it doesn't really matter)Step 3) Adjust the compass to be the width of AB. So one end of the compass is at point A, and the other end of the compass is at point B.Step 4) Keeping the same compass width, transfer the compass to the line through point C. Place the nonpencil part at point C. Then draw an arc that intersects the new line.Step 5) The intersection of the arc and line forms point D.

So far, segment CD is the same length as AB. So we can say AB = CD.

Let's keep going

Step 6) Place the nonpencil part of the compass at point D and draw another arc to intersect line CD. Make sure you do not intersect at point C, but rather the point on the other side of D. Call this point E. Step 7) Use a marker or pen to highlight everything from C to E. So you'll highlight segment CE. Erase everything else.

Segment CE is composed of CD and DE, both of which are equal to AB. In other words, AB = CD = DE. Because CD = DE, and the two segments add up to CE, this must mean that CE is twice as long as CD. Therefore, CE is twice as long as AB.

. The Barnaby Corporation issued 2,700,000 shares of stock at its beginning to shareholders.
How many shares must a shareowner own to have a majority of the shares?

Answers

Answer:

1,350,001 shares

Step-by-step explanation:

Barnaby corporation issued 2,700,00 shares of stock to its respective shareholders

A shareholder is required to own more than half of the share of the stock of a corporation inorder to have most of it.

This implies that the shareholder must have 50% + 1 inorder to attain the majority shares

Therefore, the number of shares that must by owned by a shareholder to have majority of the shares can be calculated as follows

= 50/100 × 2,700,000

= 0.5×2,700,000

= 1,350,000+1

= 1,350,001 shares
