The width of the rectangle with a perimeter of 220 inches is 38 inches.

A rectangle is a 2-dimensional shape with parallel opposite sides equal to each other and four angles are right angles.

The perimeter of a rectangle is expressed as;

P = 2( length + width )

Given the data in the question;

Let x represent the width of the rectangle.

To solve for the width ( x ), plug the given values into the perimeter formula above and solve for x.

P = 2( length + width )

220 = 2( (2x - 4 ) + x )

220 = 2( 2x - 4 + x )

220 = 2( 3x - 4 )

220 = 6x - 8

6x = 220 + 8

6x = 228

x = 228/6

x = 38

Answer:

Step-by-step explanation:

the answer is 46.989

tenths, ones, decimal, hundredths, thousandths

the answer must be greater than 46.98 but less than 47.

Equation that has the specified asymptotes for the translation of y=2/x. x=4 and y=-8  is :

y = 2 / x- 4   -  8

The graph is shifted by that many units in the positive direction if you deduct a constant from your original function's x.

The original function's graph is shifted downward by that many units if a constant is subtracted from the y value.

Your first formula was y=2/x. The vertical asymptote is discovered when the denominator's root is solved for. It is x=0 in this instance, or the y-axis.

And when x changes to ∞, y=2/∞=0. This indicates that the y-axis, or your horizontal asymptote, is at y=0.

After seeing the first graph

Now, you can see the transformation of y=2/x below. As is evident, it has shifted 2 units to the right and 8 units down with vertical asymptote at x=4 and horizontal asymptote at y=−8.

=======================================================

Explanation:

Define the following three events:

Notation like P(A) = 12/20 means the probability of event A (aka picking the plain biscuit) is 12/20 since there are 12 plain biscuits out of 20 total. I'll leave the fraction un-reduced so we can see where the 12 and 20 come from. Going from 12/20 to 3/5 has us lose vital information about the original values.

Notation like AB means a plain biscuit was selected first and then a chocolate biscuit is selected second in that exact order. I'm assuming the first selection is not replaced. This makes the probability of the second selection dependent on the first.

So,

P(AB) = P(A)*P(B given A) = (12/20)*(5/19) = 3/19

P(AC) = P(A)*P(C given A) = (12/20)*(3/19) = 9/95

P(BC) = P(B)*P(C given B) = (5/20)*(3/19) = 3/76

The last step is to add those results to get the probability of event AB, event BC or event AC of occurring. Addition is possible since the events are mutually exclusive.

P(AB)+P(AC)+P(BC) = 3/19 + 9/95 + 3/76 = 111/380

Using a system of equations, it is found that the number of votes that he received for each place is given as follows:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

He received 892 total votes, hence:

x + y + z = 892.

Total of 2029 points, hence:

3x + 2y + z = 2029.

He had 4 fewer than twice as many second-place votes as first-place votes, hence:

x = 2y - 4.

Replacing in each of the first two equations:

x + y + z = 892.

2y - 4 + y + z = 892

3y + z = 896.

3x + 2y + z = 2029

3(2y - 4) + 2y + z = 2029

8y + z = 2041.

Multiplying the first equation by -1, and subtracting the second equation from the first, we have that:

5y = 1145

y = 1145/5

The angle measures for this problem are given as follows:

15. m<2 = 18º.

16. m<1 = 79º.

17. m<UPS = 151º.

18. m<W = 131º.

19. m<1 = 34º.

20. m<1 = 147º.

Using the angle addition postulate, we have that an angle of 90º is split into two angles, angle 1 and angle 2, hence:

m<1 + m<2 = 90º.

We use this equation to solve for x as follows:

7x - 19 + x + 5 = 90

8x - 14 = 90

8x = 104

x = 104/8

x = 13º.

Hence the measure of angle 2 is given as follows:

m<2 = x + 15 = 18º.

1 and 4 are vertical angles, meaning that they are congruent, hence we can solve for x as follows:

6x + 25 = 10x - 11

4x = 36

x = 9º.

Hence the measure of angle 1 is given as follows:

m<1 = 6(9) + 25 = 79º.

Angles 4 and 5 are supplementary, meaning that the sum of their measures is of 180º, hence we solve for x as follows:

3x + 7 + 9x - 43 = 180

12x = 216

x = 216/12

x = 18.

The measure of angle UPS is:

m<UPS = m<4 + 90º = 3(18) + 7 + 90 = 151º.

From the explanation of supplementary angles in item 17, we have that:

m<W + 49º = 180º

m<W = 131º.

Complementary angles are angles whose sum of the measures is of 90º, hence:

m<2 + m<3 = 90º

m<2 + 56 = 90

m<2 = 34º.

Vertical angles are congruent, hence:

m<2 = m<1 = 34º.

The measures of the angles are:

Angles that form a linear pair are supplementary, hence:

m<1 + m<2 = 180

5x - 18 + x = 180

6x = 198

x = 198/6

x = 33.

Then the measure of angle 1 is given by:

Explanation:

Central angle AOC is 144 degrees. This means arc ABC is 144 degrees because the central angle subtends this arc.

The remaining bit of the circle is 360-144 = 216 degrees. If we placed point E somewhere on the edge of the circle, toward the bottom, then major arc AEC is 216 degrees in measure.

Notice how inscribed angle ADC subtends this 216 degree arc. So according to the inscribed angle theorem, angle ADC is half of the 216 degree arc at 216/2 = 108 degrees.

Angle APD = 180 - (angle APC) = 180 - 145 = 35 degrees

------------------------

Focus solely on triangle ADP. We have these interior angles

The three interior angles must add to 180

A+D+P = 180

A+108+35 = 180

A+143 = 180

A = 180-143

A = 37 which is the measure of angle BAD.

Given, the volume of a pine tree shaped like a cone is 3887.2 cubic feet also given that it has a radius of 8 feet,

∴ We can obtain the height of the pine tree by equating given volume with the formula and substituting the value of radius.

So, (1/3)π(8)²h = 3887.2.

(1/3).(3.14).(64)h = 3887.2.

(200.96/3)h = 3887.2.

In the expression, there are two terms with negative exponent. The second base term y has a negative exponent -2/3. The second negative exponent -6 is applied to both base terms.

The rule states that the negative exponent can be solved by reciprocating the base term i.e. a^-x=1/a^x.

Solving the negative exponent for y,

Hence, x^1/2y^-2/3=x^1/2/y^2/3.

Solving the second negative exponent -6 that applies to both terms, applying the same rule i.e. a^-x=1/a^x.

The percentage increase from the boat price of 2600 to 4100 is 57.69%

The given parametes are

Cost price = 2600

Selling price = 4100

The percentage increase in the price of the boat is calculated as

Percentage increase = (Selling price - Cost price)/Cost price * 100%

Substitute the known values in the above equation

So, we have

Percentage increase = (4100 - 2600)/2600 * 100%

Evaluate the difference in the above equation

So, we have

Percentage increase = 1500/2600 * 100%

Evaluate the quotient in the above equation

So, we have

Percentage increase = 0.5769 * 100%
