1. Length of rectangular area = 120 yards

Width of rectangular area = 120 yards

2. Maximum area = 14,400 square yards.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Total fencing Peter has = 480 yards

Now,

We can say that the total fencing he has in terms of length L and width W of the rectangle will be;

⇒ L + L + W + W = 480

⇒ 2(L+W) =480

Divide both sides by 2 to get

⇒ L+W = 240

Subtract W from both sides so we get L in terms of W;

⇒ L= 240 - W

Since, The area of a rectangle is Length times width.

So, Area = (L × W)

⇒ Area  = (240-W) W

⇒ Area  = 240W - W²

Now, By comparing the equation with an quadratic equation

ax² + bx + c , we get;

⇒ a = -1 and b = 240

Since, Area is maximum when;

W = -b/2a

W = - 240/-2

W = 120

So, for W = 120 yards area is maximum.

Hence, Length of yards = 240 - 120 = 120 yards.

(b) Maximum area of the rectangle can be found by substitute this

W = 120 in the Area equation;

So, the maximum area ,

A = 240 (120) - 120²

A = 28800 - 14400

A = 14400

Hence, Maximum area = 14,400 square yards.

Thus,

1. Length of rectangular area = 120 yards

Width of rectangular area = 120 yards

2. Maximum area = 14,400 square yards.

Answer:

Step-by-step explanation:

The value of x is 10 .

In the question ;

from the given figure , we can see that MS=SL   and KR=RL which means

that R and S are the mid points of sides ML and KL respectively .

The Mid Point Theorem states that

If the line segment adjoining the mid points of any of the sides of the triangle then the line segment is said to be parallel to the third  side and is half of the length of the third side .

which means RS parallel  to KM   and KM/2=RS  ( ... by mid point theorem)

Substituting the values of RS=2x-10 and KM=2x, we get

2x/2=2x-10

2x = 2(2x-10)

2x = 4x -20

4x-2x=20

2x=20

x=10

Therefore , the value of x is 10 .

a)

a) we know that 75% of the HCLT is paid by those folks

b) we only know that many folks pay for the HCLT, but 76% of it is paid by folks making < 120k, namely 76% of the HCLT is paid by them.

The probability of event A is 0.0012 and the probability of event B is 0.0288

There are 7 people and 4 prices.

A) The probability that Ann wins the first prize is 1/7, assuming that all 7 people have the same probability of winnig.

Then Jim is second, now the probability is 1/6 (because we don't count Ann anymore).

Soo wins the third one, with a probability 1/5.

Kira wins the last one, with a probability of 1/4.

The joint probability is the product of all the individual ones:

P(A) = 1/7*1/6*1/5*1/4  = 0.0012

B) Now we just want that Soo, Ann, Ravi, and Hans win, but the order does not matter.

So we have the same probability than above, but now we need to include the permutations of the 4 elements, so we add a factor 4!.

637.5π mm³

EXPLANATION

The volume of a cylinder is the product of its base area and its height. In this problem, the radius of the base of the cylinder is 5 mm, and its height is 25.5 mm. The volume is,

Hence, the volume is 637.5π mm³.

If the side length of the cube is x⁻² inches then the volume of the cube will be x⁻⁶ .

The volume of  the cube with side length "a" can be calculated using the formula

Volume = a³ ,

For Example : if the side length of the cube is 2m , then the volume of the cube will be

Volume = 2³  = 8m³ .

In the question ,

it is given that ,

the  side length of the cube is x⁻² inches ,

So, substituting the value of side length in the Volume formula , we get

volume = (x⁻²)³

The x and y coordinates of the line are utilized to compute the steepness of the line using the slope formula.We are aware that one of a line's most crucial qualities is its slope because it aids in determining the pace of change.

What is the point-slope form of the equation of the line?

A line's steepness can be determined by looking at its slope.Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

Using the formula

m=y2y1/2x1,

which is the change of y over the change of x, determine the slope of the line between (3,5) and (9,1).

Slope is equal to the change in y over the change in x

, or rise over run.

m=change in y /change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

m=y2−y1/x2−x1

To determine the slope, enter the values of x and y into the equation.

m=1−(5)/9−(−3)

m=-4/12

m=12/4

m=3

To replace x1 and y1 in the point-slope form yy1=m(xx1), which is derived from the slope equation

The area of the shaded section, in terms of the radius R, is:

A = 0.67*R^2

On the image we can see a circle where a section with an angle of 120° is not shaded and the rest is shaded.

Remember that the area of a circle of radius R is:

A = pi*R^2

Where pi = 3.14

Particularly, for a section defined by an angle x the area is:

A = (x/360°)*pi*R^2

In this case we have:

x = 360° - 120° = 240°

Then the area, in terms of the radius, is:

A = (240°/360°)*3.14*R^2 = 0.67*R^2

The shortest straight path they must run back to the starting line is the square root of 34 miles.

The distance run by the runners forms a right triangle. A right triangle is a polygon that has three sides. The length, base and the hypotenuse. The hypotenuse is the longest side of the right triangle.

The miles run north is the length, the miles run west is the base and the shortest straight path to the starting line is the hypotenuse.

In order to determine the hypotenuse, the Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

The equation of the function of the agency revenus in terms of x is R(x) = (50 + x) * (100 - 3x)

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

From the question, the given parameters are given as

Number of people = 50

Amount charged per person = $100

The above means that the total charges is

Total = Number of person * Amount charged per person

Rewrite as

Revenue =  Number of person * Amount charged per person

From the question, we have

The charges for each traveller reduces by $3 for each additional person

Let the number of added person be x

So, we have

Revenue =  (Number of person + x) * (Amount charged per person - 3x)

Substitute the known values in the above equation

So, we have

R(x) = (50 + x) * (100 - 3x)

Hence, the agency's revenue R as a function of x is R(x) = (50 + x) * (100 - 3x)

Using the normal approximation to the binomial distribution, there is a 0.0060 = 0.60% probability that at least 12 sales will result from mailing to the 30 prospects.

The z-score of a measure X of a normally distributed variable that has mean given by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for the binomial distribution in the context of this problem are given as follows:

n = 30, p = 0.2.

Hence the mean and the standard deviation for the approximation are given as follows:

Using continuity correction, the probability that at least 12 sales will result from mailing to the 30 prospects is P(X > 11.5), which is one subtracted by the p-value of Z when X = 11.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (11.5 - 6)/2.19

Z = 2.51

Z = 2.51 has a p-value of 0.9940.
