An acre is equal to​ 43,560 square​ feet, and there are 5280 feet in a mile. If a farm has the shape of a rectangle measuring 0.9 miles by 1.5​ miles, what is the area of the farm in​ acres?

Given the subset A, the complement of A, A' is  {6}

Given the complement of C, C is {5, 7, 9}

The universal set contains all the elements of the subsets. '  means complement = it means elements that are not in the subset but in the universal set.

To write a set in a roster form, the elements in the set are written in a row within curly brackets - { }. The elements in the set are then separated by commas.

A' = {6}

C = {5, 7, 9}

Answer: y=-37/2

Step-by-step explanation:

y=9x/8 + (-1/2)

y=9x/8 - 1/2

y=9(-16)/8 - 1/2

y=9*(-2) - 1/2

y=-18 - 1/2

y=-(18 + 1/2)

y=-(18 + 1/2)*2/2

y=-(36 + 1)/2

y=-37/2

The required solution would be 46 for a given problem (1).

The required solution would be 1 for a given problem (2).

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

We have been given that A * B= A·B + 1 and A □ B = A + B/2,

⇒ 3 *[(7 □ 3) □ (3*4)].

⇒ 3 *[(7 + 3/2) □ (3·4 + 1)].

⇒ 3 *[(17/2) □ (13)].

⇒ 3 *[17/2 + 13/2].

⇒ 3 *[30/2].

⇒ 3 * 15.

⇒ 3·15 + 1

⇒ 46

We have been given that * represents an operation defined by a*b= a^b +b,

find (1*2)*3.

⇒  a∗b = aᵇ + b

∴ (1 ∗ 2) ∗ 3 = (1²) ∗ 2 =  (1) ∗ 2 = (1)³ = 1

Therefore, the required solution would be 46 for a given problem (1) and

Answer:

  (x, y, z) = (-4, -5, 2)

Step-by-step explanation:

You want the solution to the 3×3 system of equations ...

There are many tools available for solving a system of equations. A typical hand-held graphing calculator offers at least two methods. An online graphing calculator solution is shown in the attachment.

For the attached solution, we defined z in terms of x and y using the second equation. This effectively reduces the system to a 2×2 system, which is easily solved. The same "substitution" method can be used when solving the system by hand.

The graph shows the solution to be (x, y, z) = (-4, -5, 2).

Using z = -4x -4y -34 from the second equation, the system reduces to ...

  3x -y -4(-4x -4y -34) = -15

  19x +15y = -151

and

  2x +3y +5(-4x -4y -34) = -13

  -18x -17y = 157

Writing these equations in general form, we have ...

The "cross multiplication method" gives the solution for x and y as ...

  D = (19)(17) -(18)(15) = 53

  x = (15(157) -17(151))/D = -212/53 = -4

  y = (151(18) -157(19))/D = -265/53 = -5

Then z is ...

  z = -4(-4) -4(-5) -34 = 16 +20 -34 = 2

The solution is (x, y, z) = (-4, -5, 2).

The equation of the given situation for total cost C is C = 3m + 40 where m is the number of miles.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

Given the graph,

Let's say the equation which is representing the situation is

C = (Slope)m + d

Where d is y-intercept = 40

Slope = difference in y's coordinate / difference in x's coordinate

Slope = (70 - 55)/(10 - 5)

Slope = 15/5 = 3

So the equation would be ;

C = 3m + 40

Hence "The equation of the given situation for total cost C is C = 3m + 40 where m is the number of miles".

Step-by-step explanation:

g(x) is the graph of f(x) shifted up 4 units.

The polynomial expression for the area of the room is f(x) = x^2 + 16x + 48.

Here, we are given that the side of the length of the rug = x

Now, the square rug is placed on the rectangular room such that on 2 sides the uncovered floor is 6 meters.

This means that the length of the 2 opposite sides of the rectangle will be (x + 6 + 6) = (x + 12)

Similarly, there is 2 feet of uncovered floor on the other 2 sides, which means that the length of other two opposite sides is- (x + 2 + 2) = (x + 4)

Kindly refer to the diagram below for a better clarity of how we found out the sides.

Now, the area of a rectangle = Length × Breadth

Thus, area of the room = (x + 12) (x + 4)

= x^2 + 4x + 12x + 48

= x^2 + 16x + 48

Thus, the polynomial expression for the area of the room is f(x) = x^2 + 16x + 48

We need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.

Let the amount of 28 % sugar solution be x ml.

We are given that:

10 % sugar solution = 75 ml

Total solution = 75 ml + x ml

We need the solution to be 13 % sugar solution.

So, we get that:

28 % x + 10 % ( 75 ) = 13 % ( 75 + x )

28 x + 750 = 13 ( 75 + x )

28 x + 750 = 975 + 13 x

28 x - 13 x = 975 - 750

15 x = 225

x = 225 / 15

x = 15

Therefore, we need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.

Given that A nail 6 [tex]\frac{1}{3}[/tex] inches long is driven into a board 2 [tex]\frac{2}{5}[/tex] inches thick and asked to find out how much the nail protrudes into the board.

To calculate the nail protrudes, need to subtract the length of the nail and the thickness of the board.

Length of nail protrudes= 6 [tex]\frac{1}{3}[/tex] - 6 [tex]\frac{1}{3}[/tex]

Length of nail protrudes=[tex]\frac{19}{3}[/tex]-[tex]\frac{12}{5}[/tex]

The energy required is 30 watts second.

In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or eliminated.

The voltage of a battery is 12 V and;

The charge is 2.5C.

Now, energy can be defined as the product of voltage and charge.

Therefore,

E = V × C

E = 12 × 2.5

E = 30 watt second

Hence, the energy needed by the 12 V battery to move 2.5 C through the electrical circuit is 30 watts second.

The first flight is 2 hours and second flight is 2 hours and 48 minutes

The two distances are the same (out and back),

so set them equal.

That distance is cover by having one is (rate)(time) equal to other is (rate)(time).

Let,

One time is “x” and the other is “4.8-x.”

One average rate  is 460 per hour

and the other average rate is 500 per hour.

we know , Speed = [tex]\frac{distance}{time}[/tex]

so , distance = speed × time

put in this formula we get the value of X

⇒460 x = 500 (4.8 -x)

⇒460 x = 2400 - 500x

⇒900 x = 2400

⇒x = 2.5 hours for the slower plane.

⇒4.8- x = 2.3 hours for the faster plane.

The formula speed = distance ÷ time can be rearranged, just like any other equation.

Here detail explanation about relation between speed distance and time :

The formula can be rearranged in three ways:

speed = distance ÷ time

distance = speed × time

time = distance ÷ speed

To calculate one of the variables (speed, distance or time) we need the other two.
