Answer:

the answer is 13700m²

Step-by-step explanation:

cut this shape in two parts namely

A and B

from my view it could be cut into 1. two triangles or 2. a triangle and a rectangle

I will pick 2 because it seems much more simpler

let the triangle be A

let the rectangle be B

firstly you have to cut it then separate the shape with name given when dis is done you'll have

for ∆A=length=170-70=100m

but in B the small place is 110m,but the bigger one is 160

so to find height of triangle we say

160m-110m=50m for h of A

so for B we have

length=160m, width of breath=70m

Area of the total shape=area of A + area of B

=1/2(b×h) + (L×B)

=1/2×100×50 + (160×70)

=50m×50m+11200m²

=2500+11200

=13700m²

Answer:

C)  Both pairs of opposite sides are parallel because mPN = mLM = (1/2) and mPL = mMN = - 2.

Step-by-step explanation:

The corners of a rectangle are all right angles.  The two sets of sides are parallel.  In this example:

 PL ║ MN and

 LM ║ NP

To prove that the corners are all right angles, we could compre the slopes of the two lines that form each corner.  They will be perpendicular if they are 90°.

In this example:

PL ⊥ LM and

MN ⊥ NP

So one approach Sherry may have taken is to compare the slopes of all four lines.  To prove the object is a rectangle she could show that:

1.  The sets of parallel lines have equal slopes, and

2.  The sets of perpendicular lines have slopes that are the negative inverse of each other.  (e.g., if a line has slope 5, a perpendicular line will have slope -(1/5))

To prove these points, Sherry probably used a spreadsheet to calculate each line's slopes.  See the attached spreadsheet for how she may have set up the calculations.  The slopes are the Rise/Run for each line.  Rise is the change in y and x is the change in x between the two points.

Note the green cells.  These are the slopes.  Sherry found that:

a)  PL ║ MN and LM ║ NP,  since PL and MN both have slopes of -2; and  LM and NP both have slopes of -0.5

b)  PL ⊥ LM and MN ⊥ NP, since PL and LM and MN and NP both have slopes that are the negative inverse of each other (-2 and -(1/-2) or 0.5)

Without having checked whether any of the other answer options are viable options, Sherry will likely have seen, and done, enough to have chosen option C as proof that quadrilateral PLMN is a rectangle.

The length of the string which is pulled taut as described in the task content is; 100.2 ft.

As evident in the task content; the kite is flying 85 ft off the ground, and the angle of elevation is; 58°.

It therefore, follows from trigonometric ratios that the ratio which holds true is;

sin (58°) = 85 / l

where l = Length of the string.

Therefore;

Multiply both sides by l;

l sin (58) = 85

Divide both sides by sin (58);

l = 85 / sin (58)

I = 100.2 ft (nearest tenth)

Ultimately, the length of the string as described in the task content is; 100.2 ft.

Therefore, the apportionment under Hamilton's method is:

State Apportionment

A             18

B             22

C             13

D             30

E             17

What is Hamilton's method?

To use Hamilton's method, we need to calculate each state's priority by dividing its population by the geometric mean of its current seat and the next higher integer seat.

Then, we assign seats based on priority until we reach the total number of seats (in this case, 100).

State Population Standard Quota

A              5.6                      18

B              6.8                      22

C              3.6                      12

D              3.2                      10

E              5.2                      17

To calculate priorities, we first find the geometric mean of the current seat and the next higher integer seat for each state:

State A: sqrt(18*19) ≈ 18.49

State B: sqrt(22*23) ≈ 22.94

State C: sqrt(12*13) ≈ 12.68

State D: sqrt(10*11) ≈ 10.49

State E: sqrt(17*18) ≈ 17.89

Then, we divide each state's population by its corresponding priority:

State A: 5.6/18.49 ≈ 0.303

State B: 6.8/22.94 ≈ 0.296

State C: 3.6/12.68 ≈ 0.284

State D: 3.2/10.49 ≈ 0.305

State E: 5.2/17.89 ≈ 0.291

We then assign seats based on priority, starting with the highest priority and rounding down to the nearest integer:

State D: 30 seats

State A: 18 seats

State E: 17 seats

State B: 22 seats

State C: 13 seats

This adds up to 100 seats, as required.

Therefore, the apportionment under Hamilton's method is:

State Apportionment

A             18

B             22

C             13

D             30

Complete question:

There are 132 entertainers who do not have red hair.

What is Percentage?

Percentage is a way of expressing a number or quantity as a fraction of 100. It is represented by the symbol "%". Percentages are commonly used to express the proportion or ratio of one quantity to another.

Percentages are widely used in many fields, including mathematics, science, finance, and economics, among others. They are a convenient way to express a relative quantity or change in quantity, and are easy to compare and interpret.

If 12% of the entertainers have red hair, then 100% - 12% = 88% do not have red hair.

To find out how many entertainers do not have red hair, we can calculate 88% of the total number of entertainers:

88% = 88/100 = 0.88

Number of entertainers without red hair = 0.88 x 150 = 132

Therefore, 132 entertainers do not have red hair.

The simplified expression of (x - 4)/2(x - 3) - (x - 1)/2x is -3/(2x).

The given expression (x - 4)/2(x - 3) - (x - 1)/2x can be simplified to;

(x - 4)/(2x - 6) - (x - 1)/2x

To solve this expression, we need to first find a common denominator for the two fractions.

The least common multiple of the denominators 2x and 2x - 6 is;

2x( x - 3)

So we'll multiply the first fraction by (x - 3)/(x - 3) and the second fraction by (x - 3)/(x - 3) to get a common denominator:

((x - 4)/(2x - 6)) · ((x - 3)/(x - 3)) - ((x - 1)/(2x)) · ((x - 3)/(x - 3))

Now we can combine the numerators over the common denominator:

((x - 4)(x - 3) - (x - 1)(x - 3))/(2x(x - 3))

Expanding the parentheses and combining like terms, we get:

(x² - 7x + 12 - x² + 4x - 3)/(2x(x - 3))

Simplifying the numerator, we get:

(-3x + 9)/(2x(x - 3))

Now we can factor out a -3/2 and simplify:

(-3/2) · (x - 3)/(x(x - 3))

The (x - 3) terms cancel out, leaving us with:

Now we have to find the difference quotient of this function, which is given as\[\frac{f(x+h) - f(x)}{h}\]

We are given that \(h ≠ 0\).

So, first let's find \(f(x+h)\).\[f(x+h) = \frac{9}{(x+h)^2}\]

Now we can put both the values of \(f(x+h)\) and \(f(x)\) in the difference quotient.

\[\frac{f(x+h) - f(x)}{h} = \frac{\frac{9}{(x+h)^2} - \frac{9}{x^2}}{h}\]

Let's put the LCM of \((x+h)^2\) and \(x^2\) which is \(x^2(x+h)^2\) in the numerator.

\[\frac{\frac{9x^2 - 9(x+h)^2}{x^2(x+h)^2}}{h}\]

Now, simplify the numerator.

\[\frac{9x^2 - 9(x^2 + 2xh + h^2)}{x^2(x+h)^2h}\]\[\frac{9x^2 - 9x^2 - 18xh - 9h^2}{x^2(x+h)^2h}\]

Now we can cancel out the common factor of 9 from both numerator and denominator.

\[\frac{-2xh - h^2}{x^2(x+h)^2h}\]

Now cancel out h from both numerator and denominator.

\[\frac{-2x - h}{x^2(x+h)^2}\]

The expected loss for the retailer is $2288.4.

The retailer receives some products from three suppliers: S1, S2, and S3. The probability of successfully delivering the products in time by the suppliers are 0.85 for $1, 0.82 for $2, and 0.91 for S3. The manufacturer orders 500 units of a raw material from $1, 120 units from $2, and 156 units from $3. In case of failure to receive the materials in time, the manufacturer will bear $20 per unit for the product supplied by S1, $30 for the product supplied by S2, and $10 for the product supplied by S3. We have to calculate the expected loss for the retailer.

Let's calculate the expected loss for each supplier separately.Expected loss for supplier S1:Number of units ordered from S1 = 500The probability that the product will not be delivered in time = 1 - 0.85 = 0.15The expected loss per unit = $20Total expected loss for the products supplied by S1 = Expected loss per unit × Number of units ordered from S1 × Probability that the product will not be delivered in time= 20 × 500 × 0.15= $1500Expected loss for supplier S2:Number of units ordered from S2 = 120The probability that the product will not be delivered in time = 1 - 0.82 = 0.18

The expected loss per unit = $30Total expected loss for the products supplied by S2 = Expected loss per unit × Number of units ordered from S2 × Probability that the product will not be delivered in time= 30 × 120 × 0.18= $648 Expected loss for supplier S3:Number of units ordered from S3 = 156The probability that the product will not be delivered in time = 1 - 0.91 = 0.09The expected loss per unit = $10Total expected loss for the products supplied by S3 = Expected loss per unit × Number of units ordered from S3 × Probability that the product will not be delivered in time= 10 × 156 × 0.09= $140.4The total expected loss for the retailer = Expected loss for supplier S1 + Expected loss for supplier S2 + Expected loss for supplier S3= $1500 + $648 + $140.4= $2288.4

After calculations, we find that the company saves a total of $12 x 160 = $1,920 per month by having Alex work instead of a paid employee.

In this scenario, the company has three unpaid interns, including P. Alex, who are working in exchange for college credit. This means that the company does not have to pay these interns any salary or wages.

If the company were to hire a paid employee instead of having an intern like Alex work, they would have to pay that employee $12 per hour for the work that needs to be done. This is the amount that the company would have to spend in wages for each hour worked by the employee.

Now, we know that Alex works for the full 8 hours per day, and for 20 workdays in a month. This means that she works a total of 8 x 20 = 160 hours in a month.

Therefore, the total amount of money the company would have to pay a paid employee for the same amount of work that Alex does would be $12 per hour x 160 hours = $1,920.

Since Alex is working for the company without any payment, the company saves the entire amount of $1,920 per month that they would have had to pay a paid employee to do the same work.

The rate of increasing the area of the rectangle is 72cm²/s

We have, The length of a rectangle is increasing at a rate of 5 cm/s and its width is increasing at a rate of 4 cm/s. When the length is 13 cm and the width is 4 cm, we have to find how fast is the area of the rectangle increasing.

The area of a rectangle is given by, A = l × w

Where l is the length and w is the width.

Now we will differentiate the equation with respect to time t.

dA/dt = d/dt (l × w)

dA/dt = l(dw/dt) + w(dl/dt)

We can use this formula to calculate how fast the area of the rectangle increases when the length is 13 cm and the width is 4 cm.

Substituting the given values, l = 13 cm and dl/dt = 5 cm/s w = 4 cm and dw/dt = 4 cm/s

If $1,000 were invested in this stock, what would its value be in 2017 if the stock had increased 3.5% annually?The solution to the given problem is as follows:Calculate the value of the stock when $1,000 was invested in 2014.Using the geometric mean formula,$\text{Geometric mean} = \sqrt[n]{a_1a_2a_3\cdots a_n}$Here, $n = 3$ since the value is given for the years 2014, 2015, and 2016. $a_1 =$ the value of the stock in 2014, $a_2 =$ the value of the stock in 2015, and $a_3 =$ the value of the stock in 2016.

We have to find $a_1$.Solve for $a_1:$\[a_1 = \frac{\text{Geometric mean}}{\sqrt[n-1]{a_2a_3\cdots a_n}} = \frac{\sqrt[3]{1145}}{\sqrt[2]{1.035^2}} \approx 1042.97\]Therefore, the value of the stock when $1,000$ was invested in 2014 was approximately $1,042.97$.

Calculate the value of the stock in 2017.Using the same formula as before, we have:\[\text{Geometric mean} = \sqrt[3]{1042.97 \cdot 1.035 \cdot 1.035} \approx 1,124.54\]Therefore, the value of the stock in 2017 would be approximately $1,124.54$ dollars.Compare the results obtained from the above two parts to the value of $1,000$ of the social media stock.

The value of $1,000$ of the social media stock after three years with a 7% annual increase is given by:\[\text{Social media stock} = 1000 \cdot (1 + 0.07)^3 \approx 1225.04\]Therefore, we can compare the results obtained from the two previous parts to see which one is greater. It is clear that the social media stock value of $1,000$ is greater than that of the conglomerate corporation's stock. Therefore, the correct answer is:The value of the $1,000 invested in the conglomerate corporation's stock in 2014 was less than that of the value of the $1,000 invested in the social media stock. The social media stock would earn $ more than the conglomerate corporation's stock.

Therefore , the solution of the given problem of parallelograms comes out to be s intended, overline DE and overline FB are congruent.

In Euclidean mathematics, a simple quadrilateral of two sets of equal distances is referred to as a parallelogram. In a specific kind of quadrilateral known as a parallelogram, both set of opposite sides are straight and equal. There are four types of parallelograms, 3 of which are each mutually exclusive. Rhombuses, parallelograms, squares, but also rectangles are the four distinct shapes.

Here,

We can use the midpoint theorem and the fact that the opposing sides of a parallelogram are parallel and congruent to demonstrate that overline DE is congruent with overline FB.

The midpoint theory tells us that DE EA because we first know that E is the midpoint of overline AB.

The midpoint theory tells us that BF FC because we also know that F is the midpoint of overline DC.

As a result, overline DE and overline BC are parallel, and overline BF and overline AD are parallel.

DE EA and BF FC resulted in:

=> FC = EA Plus DE (Preserving equality by adding identical lengths)

If we replace FC with EA and DE with BF, we get:

=> BF + FC = DE + DE

If we simplify, we get:

=> 2DE = 2BF

When you divide both parts by 2, you get:

=> DE = BF

We have thus demonstrated that, as intended, overline DE and overline FB are congruent.

Calculating for the upper bound of 71.8:

z2

= (71.8 - 67.2) / 4.6

= 4.6/4.6

= 1

Getting the area under curve between these two z-scores using a table of common normal probability. The normal distribution is symmetric, thus, the area between z1 and z2, can be then subtracted from the area to the left of z2. The Left of z1 is an area of 0.1587 and the left of z2 is an area of 0.8413. Therefore, the area between z1 and z2 is:

= 0.8413 - 0.1587

= 0.6826

Converting this area to a percentage -

0.6826 × 100%

= 68.26%

The standard deviation of the costs is 37 Dhs

The given mean is 173 and 3% of costs exceed 243. We have to calculate the standard deviation of the cost. Therefore, let's first start by calculating the z-score as follows;z-score formula = `(x - μ) / σ`z-score = `243 - 173 / σ`z-score = `70 / σ`We need to find the standard deviation of the costs. Since the z-score formula includes standard deviation, we can first calculate the z-score and then use it to calculate the standard deviation.Using the z-table, we can find the z-score for 3% = -1.88-1.88 = (243 - 173) / σσ = (243 - 173) / -1.88σ = -70 / -1.88σ = 37.23≈ 37The standard deviation of the costs is 37 Dhs. Hence, the correct option is as follows.Option D is the correct option.

The volume of the composite figure can be divided into two separate figures: a cylinder and a half-sphere, with the total volume being 108 cubic centimeters.

The composite figure can be divided into two separate figures: a cylinder and a half-sphere.

The formula for the volume of a cylinder is:

Volume of the cylinder = π[tex]r^2[/tex]h, where r is the radius of the cylinder and h is the height of the cylinder.

In this case, the radius of the cylinder is 3 centimeters and the height of the cylinder is 10 centimeters, so the volume of the cylinder is:

Volume of the cylinder = π[tex](3cm)^2(10cm)[/tex] = 90π [tex]cm^3[/tex]

The formula for the volume of a half-sphere is:

Volume of half-sphere = (2/3)π[tex]r^3[/tex], where r is the radius of the half-sphere.

In this case, the radius of the half-sphere is also 3 centimeters, so the volume of the half-sphere is:

Volume of half-sphere = (2/3)π[tex](3cm)^3[/tex] = 18π [tex]cm^3[/tex]

To find the total volume of the composite figure, we add the volume of the cylinder and the volume of the half-sphere:

Total volume = Volume of cylinder + Volume of half-sphere

Total volume = 90π [tex]cm^3[/tex] + 18π [tex]cm^3[/tex]

Total volume = 108π [tex]cm^3[/tex]

Therefore, the exact volume of the composite figure is 108π cubic centimeters.
