The given quadrilateral WXYZ is a parallelogram.

A parallelogram is a quadrilateral with opposite sides parallel.

The quadrilateral ABCD have congruent opposite sides only when the diagonals are bisect.

Given that the diagonals of quadrilateral WXYZ intersect at point R.

Since the R is the midpoint.

The opposite sides are equal and opposite angles are equal.

Hence we can say that the given quadrilateral WXYZ is a parallelogram.

The magnitude of length BC in the triangle ABC is equivalent to 8.49 units.

Pythagoras theorem states that -

"In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

Mathematically, we can write-

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

Given is that ABC is a right triangle, with right angle at B. Side AC has a length of 13 units. Side AB has a length of 5 units.

Using the Pythagoras theorem in the triangle ABC, we get -

AC² = BC² + AB²

BC² = AC² - AB²

BC² = (AC + AB)(AC - AB)

BC² = (13 + 5)(13 - 9)

BC² = 18 x 4

BC² = 72

BC = √(72)

BC = 8.49 units

Therefore, the length of the side BC is equivalent to 8.49 units.

In a normal distribution, a minimum percentage of 68% is anticipated, while an expected percentage of 60% is lower at 60%.

The standard deviation reveals the degree of data skewedness. It gauges how far away from the mean each observed value is.

According to the given information

8, 12, 27, 32, 45, 57, 61, 73, 82, 94 data points are provided.

Their average  mean is 49.1.

The computed standard deviation is 29.31988.

The lower and upper limits are provided by the following when one standard deviation from the mean is taken into account.

=  [ 49.1 - 29.31988, 49.1 + 29.31988 }

= [ 19.78012 , 78.41988 ]

We can observe that only six points—27, 32, 45, 57, 61 and 73—or 60% of the total—remain within one standard deviation of the mean.

The dimensions of the rectangular prism are:

Length = 4 meters.

Width = 2 meters.

Height = 2 meters.

A rectangular prism of width W, height H, and length L has a volume given by the formula:V = W*H*L

Here we know that: the height and the width are both 2 meters less than the depth, then:W = L - 2H = L - 2 and the volume is 16 cubic meters

Replacing that in the volume equation we will get:16 = L*(L - 2)*(L - 2)It is ratter easy to notice that if we take L = 4, we will get:16 = 4*(4 - 2)*(4 - 2) 16 = 4*(2)*(2)16 = 4*416 = 16 So L = 4 is a solution, then:

W = L - 2W

= 4 - 2 = 2

And also the height is:H = 4 - 2 = 2

The percentage markdown only affects the price of the baseball bat, not the price of the baseball. Therefore, the price of a baseball will remain the same at $12.

One technique to express a number as a fraction of 100 is through the use of percentage. It is typically used to denote a percentage or share of a larger whole, and it is frequently written with the sign "%." For instance, a student who obtains an 80 is referred to as having gotten a "80%" or "80%".

Percentages can be used to compare distinct numbers, to assess change over time, or to establish the proportion of a group or population that fits into a specific category. For example, a survey may state that 60% of respondents said "yes" to a certain question, or that the price of a product has grown by 10% in the last year.

How to solve.

If the price of a baseball is marked down by the same percentage as a baseball bat, then the price of a baseball will not change.

With linear inequalities in two variables, you still have y=mx+b and it still tells you the same thing.

The inequality portion adds two additional layers on top of the y=mx+b line.

If the inequality is > or <, then you draw the line as a dashed line.

If the inequality is ≥ or ≤, then you draw the line as a solid line.

The difference is that points on the > or < line do NOT make the inquality true, while points on the ≥ or ≤ line do.

The other piece is that all the points on one side of the line will also make the inequality true.

If you have "y>mx+b" or "y≥mx+b", then you shade above the line.

If you have "y<mx+b" or "y≤mx+b", then you shade below the line.

So there are three parts:

1. Where is the line?  

2. Is the line solid or dashed?

3. Do you shade above or below the line?

The three graphs are attached.

Answer:

5 hours

Step-by-step explanation:

40=8x

x=5

The number of hours taken for 8 bunnies to eat the same amount of crops will be 5 hours.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

If 5 bunnies can eat all the crops in a garden in 8 hours. The relation between work and time will be inverse. Then the product of the number of bunnies and the number of hours remains constant.

Let 'x' be the number of hours. Then the equation is given as,

8 × x = 5 × 8

Simplify the equation, then we have

8 × x = 5 × 8

8x = 40

x = 40 / 8

x = 5 hours

The number of hours taken for 8 bunnies to eat the same amount of crops will be 5 hours.

Okay, so this question really is a nightmare, because this image is just not possible. Like, literally, Z is or is not the center, you do or do not have enough info. Its a bad question. This is not your fault. If you don't care why its a bad question scroll down to "How could someone get 55°"

If Z is the center, BZ and CZ are radii and equal. Angle CBZ is 60° because

AngleABC + Angle CBZ = 180°

120° + CBZ = 180°

CBZ = 60°

That means AngleC is also 60°. And then, since 180° in a triangle, AngleCZB also must be 60°.

This makes AngleCZD 120°.

But if Z is the center and ArcCD is 115°, then AngleCZD should be 115°.

Contradiction! Angle CZD can't be both 120° and 115° something is wrong here. See image.

How could someone get 55°? Well, it is also not correct but... If ArcCD is 115° then AngleCZD is 115° (if Z is the center) So AngleCZB is 180°-115°, which is 65°.

AngleCBZ is 60°

60° + 65° + C = 180°

125 + C = 180

C = 55°

A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.

Cecil started from Point A and moved according to the expression 10 + (−5) + 19 + 6 + (−19) + 5 + (−10).

Let 'x' be the number of steps in order to return to the starting point. Then the equation is given as,

x + 10 + (−5) + 19 + 6 + (−19) + 5 + (−10) = 0

Simplify the equation, then the equation is given as,

x + 10 − 5 + 19 + 6 − 19 + 5 − 10 = 0

x + 40 − 24 = 0

x + 16 = 0

x = − 16

=4 x $21,000

= $84,000.

Then the percentages of each expenses are applied to find the values, for example, 42% of that is for employee wages, hence:

= 0.42 x 84,000
