A rectangular plot of land is to be fenced in using two types of fencing. Two opposite sides will use heavy-duty fencing selling for $4.50 a foot. The two remaining sides will use standard fencing selling for $3 a foot. How much of the heavy-duty and standard fencing should be used so that the greatest area can be fenced in at a cost of $18,000?

Answers

Answer 1

The amount of heavy-duty fencing to be used is 2000 ft for $9000 and the amount of standard fencing to be used is 3000 ft for $9000 in order to make a total cost of $18000.

How do we determine the area of a rectangular plot?

The area of the rectangular plot is denoted by the length multiplied by the width.

Let us assume that the length = x and the width = y.

Area = xy

Then, for two opposite with heavy fencing for $4.50 a foot and the standard fencing for $3 a foot, we have:

2x (4.50) + 2y(3) = 18000  ---- (1)

⇒ 9x + 6y = 18000

Make (y) the subject, we have:

[tex]\mathbf{y = \dfrac{18000-9x}{6}}[/tex]

Replace the value of y with the area of the rectangle, and we get:

[tex]\mathbf{Area =x(\dfrac{18000 - 9x}{6})}[/tex]

Area = x(3000 - 1.5x)

Area = 3000x - 1.5x²

For the area to be maximum, we take the differentiation of the Area:

dA/dx = 0

dA/dx = 3000 - 3x

x = 3000/3

x = 1000 ft

From equation (1)

2x (4.50) + 2y(3) = 18000  

x (4.50) + y(3) = 9000  

1000(4.50) + 3y = 9000

3y = 9000 -4500

y = 4500/3

y = 1500 ft

So, there are (1000× 2)ft = 2000ft heavy duty fencing for $9000, and (1500 ×2)ft = 3000ft standard fencing for $9000 to make a cost of $18000.

The area of the figure in the task content is; 14.28in².

What is the area of the figure in the task content?

The area of the figure in the task content can be evaluated as the area of the semicircle and the rectangle.

Hence, the area of the semicircle is; (3.14/2) × (4/2)² = 6.28in².

The area of the rectangle can be evaluated as; 2 × 4 = 8in².

Hence, the area of the entire figure is; 8+ 6.28 = 14.28in².

Answers

Answer:

please see explanations

Step-by-step explanation:

For the first question,

Sum of angles in a triangle equal180°

3x + 4x + 2x = 180

9x = 180°

Dividing bothsides by 9

9x/9 = 180/9

x = 20

The measure of the interior angles are :

3x = 3(20) = 60

4x = 4( 20) = 80

2x = 2(20) = 40

For the second question,

Let's find x first.

Angles on a straight line equal 180°.

x + 92 = 180

x = 180 - 92 = 88°

To find A note that:

Exterior angle equal sum of opposite interior angles.

A = 88° + 43°

A = 131°

Answer:

m∠R = 112°

m∠S = 112°

m∠T = 68°

Step-by-step explanation:

Quadrilateral QRST is a cyclic quadrilateral.

A cyclic quadrilateral is a quadrilateral drawn inside a circle where every vertex touches the circumference of the circle.  

The opposite angles in a cyclic quadrilateral sum to 180°.

⇒ m∠Q + m∠S = 180°

⇒ m∠R + m∠T = 180°

Given:

m∠Q = 68°m∠R = (3x + 40)°m∠T = (5x - 52)°

Measure of angle Q

⇒ m∠Q + m∠S = 180°

⇒ 68° + m∠S = 180°

⇒ m∠S = 180° - 68°

m∠S = 112°

Measure of angles R and T

⇒ m∠R + m∠T = 180°

⇒ (3x + 40)° + (5x - 52)° = 180°

⇒ )8x -12)° = 180°

⇒ 8x° = 192°

⇒ x = 24

Substituting the found value of x into the expressions for angles R and T:

⇒ m∠R = (3(24) + 40)°

m∠R = 112°

⇒ m∠T = (5x - 52)°

m∠T = 68°

Answer:

Step-by-step explanation:

The given relations between numbers and prices can be used to write a system of equations for the number of each kind of ticket. One equation will describe ticket numbers; the other will describe ticket revenue.

Setup

Let x represent the number of adult tickets, and y the number of student tickets. The given relations can be written as the general-form equations ...

  8x -y -11 = 0 . . . . . . . . . ticket numbers

  5x +3y -895 = 0 . . . . . ticket revenue

Solution

The setup using general form equations lends itself to solution using the "cross multiplication method." Using this method, we define three numbers used in the solution:

  Δ = 8(3) -5(-1) = 24 +5 = 29

  Δx = -1(-895) -3(-11) = 895 +33 = 928

  Δy = -11(5) -(-895)(8) = -55 +7160 = 7105

And the solutions are ...

  x = Δx/Δ = 928/29 = 32

  y = Δy/Δ = 7105/29 = 245

32 adult tickets and 245 student tickets were sold.

It asks how long until they're both saving it serving pizza again. Alright. So we can kind of just write them out and say well, if it's every 20 days, it repeats. Well then in 20 days from now we're going to get pizza again. And then after that another 20 days, so 40 days and then after that another 60 days. Okay. And we're just adding 20 each time. Uh you know, to see when would we get pizza again at the elementary school? Well, we can do the same thing here with middle school. And when are they going to get pizza again? Well, in 15 days from now they would get pizza again and then another 15 days from that. So that's 30 And then 45 and then 60 and then 75 and so on. And the first time that they're going to repeat is well, this is the common factor that are the common multiple that they have, which is 60. This is really just a complicated way of asking what is the least common multiple of 20 and 15. Alright. And your answer is going to be 60. So it'll be 60 days until they serve the same pizza again.
