The measure of the smallest angle of a tree with a hill is 60°.

The measure of the greatest angle of a tree with a hill is 120°.

Given:

A tree on a 30° slope grows straight up.

To find:

The measures of the

greatest and smallest angles the tree makes with the hill.

Solution:

In figure drawn:

\(\angle PQR = 30^o\)

AB= Straight three

Construction:

Draw a parallel line CA to QR through point A.

Now,

\(\angle PQR = \angle PAC = 30^o\\\\\angle PAC +\angle PAB = 90^o \text{(Complimentary angles)}\\\\\angle PAB = 90^o -\angle PAC\\\\angle PAB=90^o-30^o=60^o\)

The measure of the smallest angle of a tree with a hill is 60°.

\(\angle PAB + \angle BAQ= 180^o\text{(Supplementary angles)}\\\\ \angle BAQ= 180^o-\angle PAB \\\\ \angle BAQ=180^o-60^o=120^oC\)

The measure of the greatest angle of a tree with a hill is 120°.

Answer:

$58.40

Step-by-step explanation:

Really simple stuff here once you know how percentages work.

10% of 73.00 is 7.30, which means that if we do:

7.30 * 2 that means we have 20%

So, 7.30 * 2 = 14.60

73.00 - 14.60 = $58.40

We can check this by doing

7.30 * 8 = $58.40

Answer:

Step-by-step explanation:

Answer:

the numbers are missing, so I looked for a similar question:

A fence must be built to enclose a rectangular area of 20,000 ft². Fencing material costs $2.50 per foot for the two sides facing north and south and $3.20 per foot for the other two sides. Find the cost of the least expensive fence.

we must first write down the area and perimeter equations, where X = sides facing north and south, and Y = sides facing east and west.

area ⇒ XY = 20000

perimeter ⇒ P = 2X + 2Y

X = 20,000 / Y

now we replace X in the second equation:

P = 2 · 20000/Y + 2Y

P = 40000/Y + 2Y

now we write down our cost equation:

cost = C(y) = (2.50 · 40000/Y) + (3.20 · 2Y)

cost = C(y) = 6.4Y + 100000/Y

to determine the minimum cost we must find the derivative of the cost equation:

C'(y) = 6.4 - 100000/Y²

now, C'(y) = 0

0 = 6.4 - 100000/Y²

100000/Y² = 6.4

Y² = 100000/6.4 = 15,625

Y = √15,625 = 125

this means that Y = 125 feet

X = 20000/125 = 160 feet

perimeter = (2 · 160) + (2 · 125) = 320 + 250 = 570 feet

cost of fence = (320 · $2.50) + (250 · $3.20) = $1,600

Answer:

1) y > x

2) x > 5 > y

3) x ≤ 4  ( or 4 ≥ x )

4) x = y

Step-by-step explanation:

1) 1. y is greater than x

  2. so y > x

2) 1. 5 is less than x and more than y

   2. we can write this like x > 5 > y

   3. you can just squish them together as a shortcut usually: x > 5 and 5 > y      -->      x > 5 > y

3) 1. x is for at most, we can say this as x is less than or equal to 4

   2. this is written as x ≤ 4  or  4 ≥ x

4) 1. x - y = 0 so x and y must be the same value

   2. therefore x = y

Answer:

the collection center should be located at Collection Option (D).

Step-by-step explanation:

To determine the best location for the collection center, you can calculate the average coordinates of the four collection points and choose the location that is closest to this average.

To calculate the average coordinates, you can add the coordinates of each collection point and divide the result by the number of collection points. For example, to find the average X coordinate, you can add the X coordinates of all four collection points and divide by 4. Similarly, to find the average Y coordinate, you can add the Y coordinates of all four collection points and divide by 4.

Using this method, the average coordinates for the four collection points are (5.75,3.25). The collection point that is closest to these average coordinates is Collection Point D, which is located at (7,3). Therefore, the collection center should be located at Collection Point D.

I hope this helps to clarify the process for determining the best location for the collection center. Please let me know if you have any other questions.

You invested $3000 at 3% annual interest rate, and the remaining amount of $4000 - $3000 = $1000 was invested at 4% annual interest rate.

Let's assume you invested an amount, x, at 3% annual interest rate. This means the amount invested at 4% annual interest rate would be $4000 - x.

To calculate the interest earned from the investment at 3%, we multiply x by 3% (0.03). Similarly, the interest earned from the investment at 4% is calculated by multiplying ($4000 - x) by 4% (0.04).

According to the given information, the total interest earned from both investments is $130. So we can set up the equation:

0.03x + 0.04($4000 - x) = $130

Simplifying the equation:

0.03x + 0.04($4000 - x) = $130

0.03x + $160 - 0.04x = $130

-0.01x = $130 - $160

-0.01x = -$30

x = -$30 / -0.01

x = $3000

Therefore, you invested $3000 at 3% annual interest rate, and the remaining amount of $4000 - $3000 = $1000 was invested at 4% annual interest rate.

Answer:

The sample size is    \(n = 68 \)

Step-by-step explanation:

From the question we are told that

    The margin of error is  \(E = 5 \ years\)

     The standard deviation is  \(\sigma = 22\)

From the question we are told the confidence level is  94% , hence the level of significance is    

      \(\alpha = (100 - 94 ) \%\)

=>   \(\alpha = 0.06\)

Generally from the normal distribution table the critical value  of  \(\frac{\alpha }{2}\) is  

   \(Z_{\frac{\alpha }{2} } =  1.881\)

Generally the sample size is mathematically represented as  

   \(n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2\)

=>  \(n = [\frac{1.881 } *  22 }{5} ] ^2\)

=>  \(n = 68 \)

The amount of work done is Option A) 12 N/m

Work done is simply defined as the product of the magnitude of displacement, (d) and the component of the force that in the direction of displacement.

It measures energy transfer that occurs when an object is moved to a distance by an external force which is applied in the direction of the displacement.

Work done on a body is equivalent  to the increase in the energy of the body, because it transfers energy to the body.

The formula for work done is;

W = fd

Where, 'f' is the applied force and d is the distance

Substitute the values

Work done = 6(2)
