The length of the side of a quadrilateral are 6 cm, 5 cm, 8cm. and 11cm the perimeter of
the similar quadrilateral is 20 cm.
Find the length of the sides of the second, quadrilateral

Answers

Answer 1

Answer:

Step-by-step explanation:

Let's call the side lengths of the first quadrilateral a, b, c, and d, and the side lengths of the second quadrilateral A, B, C, and D. We are given that the perimeter of the second quadrilateral is 20 cm, and that the quadrilaterals are similar. This means that the ratio of the side lengths of the two quadrilaterals is the same for all four sides. Let's call this ratio r. Then we have:

A + B + C + D = 20 cm

and

A/a = B/b = C/c = D/d = r

We can find the value of r by taking the ratio of any two sides of the quadrilaterals. For example, we can take the ratio of A to a:

A/a = r

Substituting the expressions for A and a in terms of r, we get:

(ra)/a = r

Solving for r, we get:

r = a/a = 1

This means that the ratio of the side lengths of the two quadrilaterals is 1. Therefore, the side lengths of the second quadrilateral are equal to the side lengths of the first quadrilateral. Substituting the given values for the side lengths of the first quadrilateral, we get:

A = 6 cm

B = 5 cm

C = 8 cm

D = 11 cm

Therefore, the side lengths of the second quadrilateral are A = 6 cm, B = 5 cm, C = 8 cm, and D = 11 cm.

Answer:

The area of the triangle is 168 meters

Step-by-step explanation:

Formula to find the area of a triangle:

Area = 1/2 Base x Height

So, first you need to identify the base and the height. The base is 16m + 8m, and the height is 14m. All you have to do is plug in the numbers:

Area = 1/2 (16 + 8) x 14

Then, you solve:

Area = 1/2 (16 + 8) x 14

Area = 1/2 24 x 14

Area = 1/2 336

Area = 168 meters

So, the area of the triangle is 168 meters

It's almost like drawing any other graph. Here, you need to pay attention to the domain on which each piece is defined. You need to add dots where the function is discontinuous to show how the function is defined at the discontinuity.

__

1) The dividing line is at x=2.

To the left of that line, the graph is the constant function y=3.

To the right of that line, the graph is the quadratic function y = (x-3)².

The dots are placed where x=2 (at the boundary between the parts of the function). A solid dot is placed on the end of the horizontal line, since that is the function value at x=2. An open dot is placed on the end of the parabola, since the function is not defined at that point (2, 1).

The graph is shown in the first attachment.

__

2) Here, the dividing line between the pieces is at x=-4. Again, the function is constant to the left of that line. To the right of that line, it is a line with a slope of 2 and a y-intercept of 3. The treatment of dots at the ends of the curve is the same, since the function is defined at x=-4 as the left piece, not the right piece.

The graph is shown in the second attachment.

Expression:

Simplified (combined) expression:​

Answers

Answer:

Total score → (9p + m - 1)

Step-by-step explanation:

Points scored by the football team in quarter 1 = 3p

Score in quarter 2 = (5p + 2)

Points scored in quarter 3 = (p - 4)

Score of quarter 4 = (m + 1)

Total points scored in entire game = 3p + (5p + 2) + (p - 4) + (m + 1)

                                                          = (3p + 5p + p) + m + (2 - 4 + 1)

                                                          = 9p + m - 1

Expression representing the total score by the team in entire game will be,

Paired or independent? To construct a confidence interval for each of the following quantities, say whether it would be better to use paired samples or independent samples, and explain why.

b. The mean difference in height between men and women.
c. The mean difference in apartment rents between apartments in two different cities.
d. The mean difference in apartment rents in a certain town between this year and last year.

Answers

Answer:

Paired or Independent Samples

Quantities   Samples

a.                 Paired Samples because the heights of the identical twins are dependent on each other.

b.                 Independent Samples; the height of men and women are independent of the other.

c.                 Independent Samples; rents in two different cities are not expected to be dependent on each other.

d.                Paired Samples; rent in a certain town between this year and last year are dependent on each other.

Step-by-step explanation:

Paired Samples are used when there is a natural or matched coupling such that a data set is generated in which each data point in one dependent sample is uniquely paired to a data point in the second dependent sample.  In this case, the two samples are dependent on each other.

Independent Samples are used when there is a random selection of samples because their observations are independent.

Required

P(Even)

The even sides are: 2, 4, 6

So:

[tex]P(Even) = P(2) + P(4) + P(6)[/tex]

This is then calculated as:

[tex]P(Even) = \frac{n(2)}{Total} + \frac{n(4)}{Total} + \frac{n(6)}{Total}[/tex]

Replace n(2), n(4), n(6) with their frequencies

[tex]P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}[/tex]

The total frequency is:

[tex]Total =42+51+39+52+44+48[/tex]

[tex]Total =276[/tex]

So:

[tex]P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}[/tex]

[tex]P(Even) = \frac{51}{276} + \frac{52}{276} + \frac{48}{276}[/tex]

Take LCM

[tex]P(Even) = \frac{51+52+48}{276}[/tex]

[tex]P(Even) = \frac{151}{276}[/tex]

[tex]P(Even) = 0.547[/tex] --- approximated

Laurie sold a house and made a commission of $14,050. She charges
her customers a commission fee of 2.5% on the selling price of the house.
How much was the selling price of the house Laurie sold?

Answers

First divide 100 by 2.5 = 40
40x14,050 = $562,000
To verify $562,000x2.5% = $14,050

The selling price of the house Laurie sold is $562,000

The cost of the house is $562000

What are percentages?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”

Given here Laurie  charges her customers a commission fee of 2.5% on the selling price of the house. Let the selling price of the house be x then according to the question we have

2.5% of x = 14,050

             x=  14,050 × 100/2.5

               = $562000

Hence, the cost of the house is $562000

For a polynomial p(x), the value of p(3) is −2. Which of the following must be true about p(x)?

A) x−5 is a factor of p(x).
B) x−2 is a factor of p(x).
C) x+2 is a factor of p(x).
D) The remainder when p(x) is divided by x−3 is −2.

Answers

Answer:

D

Step-by-step explanation:

If the polynomial p(x) is divided by a polynomial of the form x+k (which accounts for all of the possible answer choices in this question), the result can be written as

p(x)/x+k = q(x) + r/x+k

where q(x) is a polynomial and r is the remainder. Since x+k is a degree-1 polynomial (meaning it only includes [tex]x^{1}[/tex] and no higher exponents), the remainder is a real number.

Therefore, p(x) can be rewritten as p(x) = (x+k)q(x) + r, where r is a real number.

The question states that p(3) = −2, so it must be true that

−2 = p(3) = (3+k)q(3) + r

Now we can plug in all the possible answers. If the answer is A, B, or C, r will be 0, while if the answer is D, r will be −2.

A. −2=p(3)=(3+(−5))q(3)+0

−2=(3−5)q(3)

−2=(−2)q(3)

This could be true, but only if q(3)=1

B. −2=p(3)=(3+(−2))q(3)+0

−2=(3−2)q(3)

−2=(−1)q(3)

This could be true, but only if q(3)=2

C. −2=p(3)=(3+2)q(3)+0

−2=(5)q(3)

This could be true, but only if q(3) = −2/5

D. −2=p(3)=(3+(−3))q(3)+(−2)

−2=(3−3)q(3)+(−2)

−2=(0)q(3)+(−2)

This will always be true no matter what q(3) is.

Of the answer choices, the only one that must be true about p(x) is D, that the remainder when p(x) is divided by x−3 is -2.

The final answer is D.

The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 17 ft long, what is the volume?

Use the value 3.14 for π and round your answer to the nearest whole number.

Answers

Answer:

The volume of the cylinder is 120.10 square feet.

Step-by-step explanation:

Given that the radius of a cylindrical construction pipe is 1.5 ft, to determine its volume if the pipe is 17 ft long, the following calculation must be performed, knowing that the volume of a cylinder arises from multiplying the number pi by the radius at square of the cylinder, and that result by the height of the same:

3.14 x 1.5 ^ 2 x 17 = X

3.14 x 2.25 x 17 = X

7.065 x 17 = X

120.105 = X

Thus, the volume of the cylinder is 120.10 square feet.
