Proportion refers to the equality of two ratios. In other words, when two ratios are set equal to each other, they form a proportion. A proportion is typically written in the form of two fractions separated by an equals sign, such as a/b = c/d. Proportions are commonly used in mathematics to solve problems involving ratios and proportions, such as finding missing values or scaling up or down a given quantity.

Here,

To find out how much each farmer pays, we need to determine the proportion of the total rent that each farmer owes based on the number of sheep they have. First, we need to find the total number of sheep:

120 + 72 + 68 = 260

The first farmer has 120 sheep, which is 46.15% of the total number of sheep (120/260). Therefore, the first farmer owes 46.15% of the rent:

0.4615 x 1600 = 738.40 euros

Similarly, the second farmer has 72 sheep, which is 27.69% of the total number of sheep (72/260). Therefore, the second farmer owes 27.69% of the rent:

0.2769 x 1600 = 443.04 euros

The third farmer has 68 sheep, which is 26.15% of the total number of sheep (68/260). Therefore, the third farmer owes 26.15% of the rent:

0.2615 x 1600 = 418.56 euros

Now, we can find the area of the first cutout:

[tex]s(cutout1) = \frac{\pi \times {r}^{2} \times \alpha }{360°} = \frac{\pi \times {18}^{2} \times 114°}{360°} = \frac{36963\pi}{360°} = 102.6\pi[/tex]

We can also find the altitude of the first triangle using trigonometry:

[tex] \sin(∠obd) = \frac{od}{ob} [/tex]

We also need to find AB by using the Pythagorean theorem:

[tex] {ad}^{2} = {ao}^{2} - {od}^{2} = {18}^{2} - {5.56}^{2} = 293.0864[/tex]

[tex]ad > 0[/tex]

[tex]ad = \sqrt{293.0864} ≈ 17.12[/tex]

[tex]ab = 2 \times 17.12 = 34.24[/tex]

[tex]h1 = od = ob \times \sin(∠obd) = 18 \times \sin(18°)≈5.56[/tex]

Then, we can find the area of the 1st triangle:

[tex]s (1triangle)= \frac{1}{2} \times 5.56 \times 34.24 ≈95.19[/tex]

And we can also find the area 1:

[tex]area1 = s(cutout1) - s(triangle1) = 102.6\pi - 95.19≈225.25[/tex]

Now let's do the same thing with the second area:

[tex]s(cutout2) = \frac{\pi \times {r}^{2} \times \alpha }{360°} = \frac{\pi \times {18}^{2} \times 131°}{360°} = \frac{42444\pi}{360°} =117.9 \pi[/tex]

[tex] \sin(∠obe) = \frac{oe}{oc} [/tex]

[tex]h2 = oe = oc \times \sin(∠obe) = 18 \times \sin(24.5°)≈7.46[/tex]

[tex] {be}^{2} = {bo}^{2} - {oe}^{2} = {18}^{2} - {7.46}^{2} = 268.3484[/tex]

[tex]be > 0[/tex]

[tex]be = \sqrt{268.3484} ≈16.38[/tex]

The area of the shaded segments in the circle is 422.5 square meters

Given that

Radius = 18 meters

Angles = 114 degrees and 131 degrees

The area of the shaded segments is the sum of the area of the individual segments and this is calculated as

Segment area =  (½) × r² × [(π/180) θ – sin θ]

Using the above, we have

Shaded segments = (½) × 18² × [(114π/180) – sin (114)] + (½) × 18² × [(131π/180) – sin (131)]

To approximate the value of log(3)15309 using log(3)7 = 1.7712, we can use the following steps:

Express 15309 as a power of 3:

15309 = 3^x

Take the logarithm base 3 of both sides:

log(3)15309 = x

Use log rules to simplify the expression:

log(3)15309 = log(3)(3^x)

log(3)15309 = x * log(3)3

log(3)15309 = x * 1

log(3)15309 = x

Substitute the value of x by using log(3)7 = 1.7712:

log(3)15309 ≈ 1.7712 * log(3)81 (since 81 is the largest power of 3 that is less than 15309)

log(3)15309 ≈ 1.7712 * 4

log(3)15309 ≈ 7.0848

Therefore, log(3)15309 ≈ 7.0848.

In conclusion MN is approximately 8.73.

How to solve?

In triangle MNK, we know that MN = NK and the angle between them is 110 degrees. Let's call the third angle in this triangle A.

We also know that MK = 5.

Since the sum of the angles in a triangle is always 180 degrees, we can find angle A:

A + 110 + A = 180

2A = 70

A = 35

Now we can use the Law of Sines to find MN:

MN/sin(110) = MK/sin(A)

MN/sin(110) = 5/sin(35)

MN = 5×sin(110)/sin(35)

MN ≈ 8.73

Using compound interest, we can find that at age 59 retirement option 1 will be better than retirement option 2.

Compound interest is computed on the principal and the accrued interest for a given time period. The interest that has accumulated on the principal over time is added to it, and the combined amount acts as the new principal for the subsequent time period. Once more, the interest for the following period is calculated using the total cumulative principal amount.

Compound interest is the term used to describe the method of computing interest employed in all financial and business transactions globally. The benefit of compounding is that it is consistently better than or comparable to other strategies, such simple interest.

At age 59,

Option 1 = 30000 × 34

= $1020000

Option 2 = 15000 (1+12/408) ^34

= 15000 × (1.02) ^34

= 15000 × 1.9606

= $29409.

So, when you retire at 59, option 1 is better than option 2.

The equation of the tangent line to the graph of y = xlnx at the point (2,2ln2) is y = (ln(2) + 1)x - 2ln2 - 2.

A tangent is a straight line or plane that touches a curve or curved surface at a single point, but does not intersect it at that point. The tangent line can be thought of as the instantaneous rate of change of the curve at that point. In calculus, the slope of the tangent line at a point on a curve is defined as the derivative of the curve at that point. The tangent line is often used to approximate the behavior of the curve near the point of tangency.

To find the equation of the tangent line to the graph of y = xlnx at the point (2,2ln2), we need to use the slope-point form of the equation of a line.

First, we find the slope of the tangent line by taking the derivative of the function y = xlnx:

y = xlnx

y' = ln(x) + 1

At x = 2, we have:

y' = ln(2) + 1

So the slope of the tangent line at (2,2ln2) is ln(2) + 1.

Next, we use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where (x1, y1) is the given point, and m is the slope we just found.

Substituting x1 = 2, y1 = 2ln2, and m = ln(2) + 1, we get:

y - 2ln2 = (ln(2) + 1)(x - 2)

Expanding and simplifying, we get the equation of the tangent line:

y = (ln(2) + 1)x - 2ln2 - 2

So the equation of the tangent line to the graph of y = xlnx at the point (2,2ln2) is y = (ln(2) + 1)x - 2ln2 - 2.

X=-10 when the points (-5, 6) and (x, 3) are elements of an inverse variation.

A relationship between two variables known as an inverse variation occurs when one variable increases while the other decreases, resulting in a constant product. Y = k/x, where k is a constant of variation, can be used to explain the relationship between two variables x and y if they are inversely proportional in mathematics.

The fact that their product must be constant allows us to determine the value of x because the points (-5, 6) and (x, 3) are components of an inverse variation.

As a result, x must be 10 to provide the elements of an inverse variation (-5, 6) and (x, 3).

x * 3 = -5 * 6

x = -30/3

x = -10

In conclusion, an inverse variation is a mathematical connection where the product of two variables stays constant.

Step-by-step explanation:

Number of favorable outcomes/Number of trails =4/20 or 1/5

Answer:

1. 33 foot

2. 6.2 foot

Step-by-step explanation:

1.

Let's denote the height of the tree by "h". We can use the tangent function to solve the problem:

tangent of the angle of elevation = opposite / adjacent

In this case, the opposite side is the height of the tree, and the adjacent side is the distance from the tree to the point on the ground where the angle of elevation is measured. So we have:

tan(35) = h / 47

To solve for "h", we can multiply both sides by 47:

h = 47 tan(35)

Using a calculator, we get:

h ≈ 32.9 feet

So the height of the tree to the nearest foot is 33 feet.

2.

Let's call the distance we're trying to find "x". We can use trigonometry to relate the angle and the length of the guy wire to the distance "x". Specifically, we can use the sine function:

sine of the angle = opposite / hypotenuse

In this case, the opposite side is the distance "x", and the hypotenuse is the length of the guy wire, which is 8 feet. So we have:

sin(51) = x / 8

To solve for "x", we can multiply both sides by 8:

x = 8 sin(51)

Using a calculator, we get:

x ≈ 6.2 feet

So the stake is about 6.2 feet from the foot of the stop sign, to the nearest tenth of a foot.

The equation we are to rewrite is:

y = |x − 3| + |x + 2| − |x − 5|, if -2 < x < 3  

Modulus value means that it always gives positive value. Thus:

if x < a, then |x - a| is positive when |x - a | = a -x, which is positive as a is larger than x.

and if x >a, then |x-a| is positive when |x-a| = x - a, which is positive as a is smaller than x.

For  -2 < x < 3,

|x - 3 | = 3 - x, as x <3

| x + 2 | = | x - (-2)| = x - (-2) = x+2 as x> -2

The correct equation to find the measure of ∠CMD is C. 15° + 30° = a; 90° – a = m.

It is formed when two straight lines intersect at a single point, creating two equal and opposite angles.

This is because the angles in a triangle must add up to 180°.

In this case, ∠FMD and ∠BMC are the two angles of the triangle, and the third angle is a right angle.

Therefore, the measure of ∠CMD must be 90°.

To find the measure of ∠CMD, we must first find the sum of ∠FMD and ∠BMC.

This can be done by setting up the equation 15° + 30° = a.

We then subtract this sum from 90° to get the measure of ∠CMD, which gives us the equation 90° – a = m.

Therefore, the correct equation to find the measure of ∠CMD is

On solving the provided question we can say that Based on Sandra's research, there is a 15% probability that a randomly picked bottle is appropriately put AND is a Plastic #4 bottle.

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% since there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many disciplines, including statistics, economics, science, and engineering.

Therefore there are 15 bottles that match both requirements (well arranged and Plastic #4).

The sample has 100 bottles in total.

As a result, the likelihood that a randomly chosen bottle is appropriately put AND is a Plastic #4 bottle is:

P(properly positioned and Plastic #4) = the number of bottles that match both requirements. / The sample's total number of bottles

P(properly positioned and Plastic #4) = 15 / 100

P(properly positioned and Plastic #4) = 0.15 or 15%

This problem involves finding the height of a flagpole using trigonometry. The surveyor measures the angle of elevation from the tripod to the top of the pole and knows the distance from the base of the pole to the tripod. By using the tangent function and the given angle, we can set up an equation that relates the height of the pole to the distance and the angle. We simplify the equation and solve for the unknown height, which gives us an approximate value of 68.53 feet.

the height of the flagpole, we can use trigonometry. Let's call the height of the flagpole "h".

Using the tangent function, we can set up the following equation:

tan(26) = h / (150 + 3)

The 3 feet is added to the distance because the tripod is 3 feet tall.

Simplifying this equation, we get:

tan(26) = h / 153

To solve for "h", we can multiply both sides by 153:

h = tan(26) * 153

Using a calculator, we can evaluate the right side of the equation to get:

h ≈ 68.53

Therefore, the height of the flagpole is approximately 68.53 feet.

Step-by-step explanation:

What is a rectangular prism?

A right rectangular prism is a box-shaped object, that is, a 3-dimensional solid which has six rectangular faces. Rectangular prisms can also be oblique - leaning to one side - but the side faces are parallelograms, not rectangles. A right rectangular prismz is also called a cuboid, box, or rectangular hexahedron. Moreover, "rectangular prism" and "right rectangular prism" are often used interchangeably.

The most common math problems related to this solid are of the type right rectangular prism calc find V or find A, where the letters stand for the Volume and Area, respectively. Let's see the necessary rectangular prism formula and learn how to solve those problems quickly and easily.

How do I find the volume of a rectangular prism?

The rectangular prism volume formula is:

volume = h × w × l,

where h is prism height, w is its width, and l is its length. To calculate the volume of a cardboard box:

Find the box length. For example, it can be equal to 18 in.

Determine its width. Let's say you measured 12 in.

Find out the rectangular prism height. Assume it's 15 in.

Calculate the cuboid volume. Using the rectangular prism volume formula above, we get volume = (18 × 12 × 15) in = 3240 in³.

How do I find the area of a rectangular prism?

The surface area of the cuboid consists of 6 faces - three pairs of parallel rectangles. To find the rectangular prism surface area, add the areas of all faces:

surface_area = 2 × (h × w) + 2 × (h × l) + 2 × (l × w) = 2 × (h × w + h × l + l × w),

where h is prism height, w is its width, and l is its length.

Let's see an example of how to solve the right rectangular prism calc - find A problem. We'll come back to our example with the box and calculate its surface area:

Calculate the rectangular prism surface area. First rectangle area is 15in × 12in = 180in², second 15in × 18in = 270in² and third one 18in × 12in = 216in². Add all three rectangles' areas - it's equal to 666 in² (what a number!) - and finally multiply by 2. The surface area of our cardboard box is 1332in².

Or save yourself some time and use our rectangular prism calculator.

Finally, let's attack the right rectangular prism calc find d (that is, the diagonal) type of problem.

How do I calculate the diagonal of a rectangular prism?

To determine the diagonal of a rectangular prism, apply the formula:

diagonal = √(l² + h² + w²)

where h is prism height, w is its width, and l is its length.
