A farmer has 3000 feet of fencing to use on a new enclosure. The new enclosure will go up against existing fencing so one side does not need additional fencing. If the farmer wants to subdivide the enclosure to have 3 pens, what is the maximum total area the farmer can enclose?

Answers

Answer:

375000 ft^2

Step-by-step explanation:

From the statement that we have that it would be 1 time the length and 2 times the width because one side is not necessary and also we must take into account that it would be divided by 3 equal enclosures therefore we will use 1000 feet (3000/3) so Therefore, the perimeter would be equal to:

1000 = l + 2 * w

we solve for w:

l = 1000 - 2 * w

Also the area is equal to:

A = w * l

replacing:

A = w * (1000 - 2 * w)

A = 1000 * w - 2 * w ^ 2

We derive:

A '= 1000 - 4 * w

Let's equal 0:

1000 - 4 * w = 0

w = 1000/4

w = 250

replacing and we calculate l:

l = 1000 - 2 * 250

l = 500

A = 250 * 500

A = 15,000 ft ^ 2

Which means that for each subdivision the maximum area would be 125000 square feet and the total would be:

125000 * 3 = 375000 ft ^ 2

A bag contains 9 red marbles, 18 orange marbles, 2 yellow marbles, and 5 purple marbles. A marble is drawn at random from the bag. What is the probability that the marble drawn will not be orange?

Answers

Answer:

8/17

Step-by-step explanation:

total balls= 9 + 18 + 2 + 5 = 34

balls drawn should NOT be Orange.

so, 34 - 18 (as there are 18 orange balls)

16 balls

probability= 16/34 = 8/17

answer = 8/17

Which equation is equivalent to the following?
4x^2 + 4y^2 +16x – 24y = 34
Please answer it:(

Answers

Answer:

The correct answer is the third expression.

Step-by-step explanation:

We have the following equation:

[tex]4*x^2 + 4*y^2 + 16*x - 24*y = 34[/tex]

Let's organize it by variables, putting together the ones that have the same letter or no letter at all. We have:

[tex]4*x^2 + 16*x + 4*y^2 - 24*y = 34[/tex]

We can extract the common factor on the left side by dividing them by 4, we have:

[tex]4*(x^2 + 4*x) + 4*(y^2 - 6*y) = 34[/tex]

We need to complete the squares on the parenthesis without changing the value of the equation, to do that we will sum the proper values inside the parenthesis and those multiplied by four on the other side of the equation, we have:

[tex]4*(x^2 + 4*x + 4) + 4*(y^2 - 6*y + 9) = 34 + 16 + 36\\4*(x + 2)^2 + 4*(y - 3)^2 = 86[/tex]

The correct answer is the third expression.

Two hikers start a trip from a camp walking 15 miles due east. They turn north and walk 17 miles to a large pond. How far is the pond from base camp to the nearest tenth of a miles.

Answers

Answer:

22.7 miles

Step-by-step explanation:

The hikers start walking 15 miles due east and then they turn north and walk 17 miles to a large pond.

The shape of their journey can be represented as a right angled triangle, shown below.

To find the distance between the pond and the base camp, we need to find the hypotenuse of the triangle.

We can do this by using Pythagoras theorem:

[tex]hyp^2 = a^2 + b^2[/tex]

where a and b are the other two sides of the triangle. Therefore:

[tex]hyp^2 = 15^2 + 17^2\\\\hyp^2 = 514\\\\hyp = \sqrt{5`4} \\\\hyp = 22.7 miles[/tex]

The pond is 22.7 miles far from the base camp.

Answer:

65 = <JKL

Step-by-step explanation:

There are two expressions that represent the same thing.

The diagram shows that <JKL = 45 + x

The question states that JKL = 3x + 5

The two expressions must be equal since they represent the same thing.

3x + 5 = x + 45

Subtract 5 from both sides

3x + 5 -  5 = x + 45 - 5

3x = x + 40                     Subtract x from both sides

3x - x = x - x + 40

2x = 40                          Divide by 2

2x/2 = 40/2

x = 20

So x + 45 = 20 + 45 = 65

or

3x + 5 = 3*20 + 5 = 60 + 5 = 65

Answers

Answer:

275 ft

Step-by-step explanation:

The formula given to use for the slant height l of the cone is ;

l = (s - πr^2)/π

Now substituting the parameters given in the question, 500 π for area and radius of 15, we have

l = {500π-15^(2)π}/π

l =( 500 π -225 π)/π

l = 275 π/π

The measure of angle 1 is (10 x + 8) degrees and the measure of angle 3 is (12 x minus 10) degrees. what is the measure of angle 2 in degrees?

Answers

Answer:

82 degrees

Step-by-step explanation:

First set 10x+8 equal to 12x-10 to find that the variable is equal to 9. Then solve for 10(9)+8 which equals 98. Since angle 1 is supplementary to angle two and supplementary angles add up to 180 degrees, subtract 98 from 180 to find that your answer is 82 degrees.

When two variables has positive correlation ( When one variable increases by increasing the other) then it reprsesents Positive linear association .When two variables has negative correlation ( When one variable decreases by increasing the other) then it reprsesents Negative linear association .When two variables in which change in one variable does not correspond with constant change in the other variable, then it represents Nonlinear association.If two variables are not interdependent such that if one increasing then there is no proportional change in the other variable, then we say there is no correlation.

Hence, the correct option is D. No association.

what do the following two equations represent? 4x+2y=10 and 4x-2y=-10

Answers

they represent linear equations

The two equations, 4x + 2y = 10 and 4x - 2y = -10, represent a system of linear equations.

Why is this so?

The equations are written in standard form, where x and y are variables, and the coefficients 4, 2, -10, and -2 are constants. Each equation represents a linear relationship between x and y.

The coefficients in front of x and y determine the slope of the line, and the constants on the right side of the equations determine the y-intercept.

Solving this system of equations simultaneously can determine the values of x and y that satisfy both equations, representing the point(s) where the two lines intersect, if they intersect at all.

Maths * Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 4 : 3 : 1 by weight. Henry needs to make 120kg of concrete. He has 55kg of cement, 45kg of sand and 15kg of gravel. Which ingredient is Henry short of?

Answers

Answer:

His 55 kg of cement is 5 kg short of the 60 kg he needs.

Step-by-step explanation:

Let r be a ratio useful in determining how much of each ingredient Henry needs:

4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.

4/8 of the total 120 kg must then be 60 kg made up of cement;

3/8                                 must then be 45 kg made up of sand; and

1/8                                   must then be 15 kg made up of gravel

His 55 kg of cement is 5 kg short of the 60 kg he needs.

-a+(-b) where a= 6.05 and b= 3.611

Answers

Answer:

-9.661

Step-by-step explanation:

In the given equation, a and b are negative. The values of a and b are given. If you insert the values into the given formula, the values become negative because of "-" in front of the a and b values.

-a + (-b)   =   -6.05 + (-3.611)

Because the second value is negative, the plus sign references to adding BOTH negative values together so it is just the same as saying:

-6.05 - 3.611

This gives you -9.661

Answer:

length = 15cm, breadth = 6cm

therefore area = l * b = 15*6 = 90cm^2

second figure is also a rectangle so,

length = 12+6 =18 cm ( or 9+9) , breadth = 9cm

therefore area = l*b =18*9 = 162cm^2

third figure is a semicircle , so

This is accompanied by a contraction of the trachea, making a narrower channel for the expelled air to flow through. For a given amount of air to escape in a fixed time, it must move faster through the narrower channel than the wider one. The greater the velocity of the airstream, the greater the force on the foreign object. X rays show that the radius of the circular tracheal tube contracts to about two-thirds of its normal radius during a cough. According to a mathematical model of coughing, the velocity v of the airstream is related to the radius r of the trachea by the equation v(r)= k (r 0- r) r ^ 2, 1/2 r 0 less than r less than r0where k is a constant and r0 is the normal radius of the trachea. The restriction on r is due to the fact that the tracheal wall stiffens under pressure and a contraction greater than 1/2r0 is prevented (otherwise the person would suffocate). Determine the value of r in the interval [1/2r0, r0] at which v has an absolute maximum.
