If PQRS is a parallelogram and PQ=9x+1 and RS=13x-11, solve for x.

Answers

Applying the definition of a parallelogram, the value of x in the length of the sides of the given parallelogram is: x = 3.

What is a Parallelogram?

A parallelogram is a quadrilateral that has two pairs of opposite sides that are congruent to each other.

Given the following:

PQ = 9x + 1RS = 13x - 11

Find x by creating an equation:

PQ = RS (congruent sides)

Substitute

9x + 1 = 13x - 11

Combine like terms

9x - 13x = -1 - 11

-4x = - 12

x = 3

Therefore, applying the definition of a parallelogram, the value of x in the length of the sides of the given parallelogram is: x = 3.

The surface area of a cylinder is approximately 640.56 square meters. The radius of the cylinder is 5 meters less than the height of the cylinder. To the nearest whole meter, what are the radius and height of the cylinder?

Answers

the radius is approximately 6 meters,

height is approximately 11 meters

The radius of cylinder = 6 meter.

The height of cylinder = 11 meter.

What is cylinder?

A cylinder is a "three-dimensional object with two round flat bases and one curved side. It has a curved surface in the middle. The base and the top surface are identical".

According to the question,

Surface area of the cylinder = 640.56 m²

Let the height of the cylinder = x meters

Let the radius of the cylinder = (x-5)meters

Formula for surface area of cylinder = 2πrh ( where 'r' is the radius of the cylinder and 'h' height of the cylinder)

640.56 = 2(3.14)(x-5)(x)

640.56/(6.28) = x² - 5x

x² - 5x =102

x² - 5x - 102 =0

using quadratic equation, [-b±√(b² - 4ac)]/2a.

b = -5; a=1; c=102

x =[-(-5) ±√(-5)² - 4(1)(102)]/2

 = [5 ± √433]/2

x = 11 and -7

since x=-7 neglect negative value, we get x=11.

The height of the cylinder is 11 meters

The radius of the cylinder is  (11 - 5) = 6 meters.

Hence, The radius of cylinder = 6 meter.

The height of cylinder = 11 meter.

Which pairs of rational numbers are equivalent?

Remember that two numbers A and B are equivalent if:

A = B

The first pair given is:

-0.5 and (-1/2).

We know that 1/2 = 0.5, then (-1/2) = -0.5

So we conclude that

-0.5 and (-1/2) are equivalent.

Another equivalent pair is:

11/20 and 0.55

To check this, you can just solve the fraction in your calculator, you will see that:

11/20 = 0.55

Then 11/20 and 0.55 are equivalent.

The final equivalent pair is:

-1/50 and -0.02

Because:

-(1/50) = -(0.02) = -0.02

Then -1/50 and -0.02 are equivalent.

So far, Ricardo has scores of 13, 17, 19 and 21 points for the first four rounds of a dice game. What does he need the total score to be for the next two rounds combined in order to achieve an average score of 20 points per round for all six rounds?

Answers

Answer:

40 points

Step-by-step explanation:

The score for the first four rounds of the game is 13, 17, 19, and 21 points.

Let [tex]S_5[/tex] and [tex]S_6[/tex] be the scores of the fifth and sixth games respectively in order to achieve an average score of 20 points per round for all six rounds.

[tex]\text{Average score} = \frac{\text{Sum of the scores of all the rounds}}{\text{Total number of the rounds}}[/tex]

[tex]\Rightarrow 20=\frac{13+17+19+21+S_5+S_6}{6}[/tex]

[tex]\Rightarrow 20\times6=80+S_5+S_6[/tex]

[tex]\Rightarrow S_5+S_6=120-80=40.[/tex]

Hence, the combined score of the fifth and sixth rounds are 40 points.

and 4 is -0.0000002

Obviously the one of the negative numbers is the smallest. The bigger number with the negative sign is more negative because it is farther away from one on the number line. Therefore 2 is the smallest. That makes 4 the second smallest. 3 is larger than 1 because there are less zeros to the first non-zero digit. That places the order from least to greatest as:

Answer:  see proof below

Step-by-step explanation:

Given: A + B + C = π                →      A + B = π - C

                                                         B + C = π - A

Cofunction Identities:       sin [(π/2) - A] = cos A

                                          cos [(π/2) - A] = sin A

Sum to Product Identity:   sin A - sin B = 2 cos [(A + B)/2] · sin [(A - B)/2]

Pythagorean Identity:       cos²A + sin²A = 1    →   cos²A = 1 - sin²A

Even/Odd Identity:           cos (-A) = -cos(A)

Proof LHS → RHS:

LHS:                      cos [(B + C) - A] - cos [(A + C) - B] + cos [(A + B) + C]

Given:                   cos [(π - A) - A] - cos [(π - B) - B]  + cos [(π - C) - C]

                         =  cos (π -2A) - cos (π -2B) + cos (π -2C)

Cofunction:          cos (-2A)  - cos (-2B) + cos (-2C)

Even/Odd:            -cos (2A) + cos (2B) - cos (2C)

Double Angle:     -(2cos²A - 1) + cos (2B) - cos (2C)

                           = 1 - 2cos²A + cos (2B) - cos (2C)

Sum to Product:    1 - 2cos²A - 2sin(B+C) · sin (B-C)

Cofunction:             1 - 2cos²A - 2sin A · sin (B - C)

Pythagorean:         1 - 2(1 - sin²A) - 2sin A · sin (B - C)

Answer:

C. Natural Numbers

Step-by-step explanation:

Before we determine what groups [tex]\sqrt{100}[/tex] fits into, we must simplify it.  We get the number 10, which is much easier to categorize.  Out of the four options, the natural numbers are the smallest group, containing only the numbers we use to count (i.e. 1, 2, 3, 4 ...).  We know that 10 fits into this category because 10 is a non-zero whole number.  Since the natural numbers contain 10 and are the smallest subset, the answer is C.

As a note: 10 will also fit into the whole numbers and rational numbers since all natural numbers are parts of these two groups as well.  These groups contain more numbers, however, making them larger than the natural number set so we can eliminate them.  10 is also not an irrational number since we can accurately define it with a fraction.
