One of the key points for two figures to be similar is that the angles are the same.

Since parallelograms have opposite angles equal, and adjacent angles sum up to give 180 degrees. We know that ABC

Angle = 180 - 523 = 127

And this makes the similarity makes the order of similarity here to be

BCD = EFGH

o,

dD = GH

Hope this Helps!!!

EXPLANATION

The first equation is a line with the following slope-intercept form:

Subtracting -4x to both sides:

Dividing both sides by 4:

Simplifying:

The slope is -1 and the y-intercept is -2

Applying the same reasoning to the second equation we get:

Final Answer

Remaining Angle= 102

Answer:

102

Step-by-step explanation:

If you add all of the angles (175+29+54) it gives you 258. As you may already know, a quadrilateral's angles have to all equal 360 combined. When you subtract 360-258, you get 102. Hope this helped! :)

A) none of these

B) only mean because if we replace 32 by 16 sum will decrease and so mean will decrease

C) both mean and median because when we remove some value os starting total sum will decrease and hence mean decrease

median will change because after remove some values total number will decrease and hence value will change

d)Negative skewed

Measures of central tendency are the values that characterize a data set by indicating the data's central location. Mean, Median, and Mode are the three primary metrics for determining central tendency.Mean is the product of the sum of all observations and the total number of observations.

An ordered set's median is its middle or centre value.

The most frequent value in a data set is called the mode.

Given that :32, 38, 42, 42, 43, 44, 46, 46, 47, 47, 49, 49, 51, 51, 51, 51, 52, 53, 53, 53, 53, 53

32, 38, 42, 42, 43, 44, 46, 46, 47, 47, 49, 49, 51, 51, 51, 51, 52, 53, 53, 53, 53, 53

mean = [tex]\frac{sum of observation}{number of observation}[/tex]

mean = [tex]\frac{1046}{22}[/tex]

= 47.54

The median is calculated by sorting the scores into numerical order, dividing the total by two, rounding the result up to get the median position, or using an even number of scores, averaging the median position's value with the following position's value.

here n = 22 which is even

median =[tex]\frac{\frac{n}{2}term +(\frac{n}{2}+1 )term }{2}[/tex]

[tex]\frac{\frac{22}{2}term +(\frac{22}{2}+1 )term }{2}\\ = \frac{11 term + 12 term}{2}[/tex]

= 49

Organize the numbers in a set in whatever order—from lowest to highest or highest to lowest—and then tally the frequency with which each number appears in the group. The mode is the one that shows up most frequently.

mode = 53 as it is repeated more times.

A) none of these

B) only mean because if we replace 32 by 16 sum will decrease and so mean will decrease

C) both mean and median because when we remove some value os starting total sum will decrease and hence mean decrease

median will change because after remove some values total number will decrease and hence value will change

The probability of getting an even number greater than 800 is 0.08

Total outcomes possible when a three-digit number is formed without repetition:

Using the digits 3,4,5,6,7 and 8:

The first digit can be filled in using any of the 6 options

The second digit can be filled using the remaining 5 options

The third digit can be filled in using the remaining 4 options

So, total outcomes possible = 6*5*4 = 120 possibilities

Now, finding even number greater than 800:

The first digit can only be filled by 8 for a number to be greater than 800 which means there is only one option for the first digit

The second digit can be filled using any of the remaining options except 8 which means there are 5 options

The last digit can be filled using 4 and 6 because these are the only even numbers which mean 2 options

Total possible outcomes = 1*5*2 = 10 possibilities

The maximum value of P = 11.

Given: P = -x + 6y

In this question we have to first solve the given system of equations.

Ignore the greater or lesser than sign that is:

y = -2x+ 4 -------- 1

And y = x + 1 ---------  2

On solving these two equations we get;

0= -3x + 3

⇒ -3x = -3

⇒ x= 1

Substituting the value of x in equation 2 we get

y = x+ 1

= 1 + 1 = 2

Thus y = 2 and x = 1

So on putting these values in P = -x + 6y we get

P = - 1 + 6× 2

P = - 1 + 12 = 11

Therefore P= 11.

Using the similar triangle principle, the height of Dixon in feet is 6 feet.

Ariadne's shadow is 15 feet long and Dixon's shadow is 18 feet long.

Ariadne is 5 feet tall.

The height of Dixon can be found using similar triangle principle.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Therefore, using the similar triangle theory,

Let

x = height of Dixon

Hence,

shadow length of  Ariadne / Ariadne height = Dixon shadow length / Dixon height

shadow length of  Ariadne = 15 ft

Ariadne height  = 5 feet

Dixon shadow length = 18 feet

15 / 5 = 18 / x

cross multiply

15 × x = 18 × 5

15x = 90

divide both sides by 15

15x / 15 = 90 / 15

x = 6 ft

Therefore, Dixon height is 6 feet.

What is linear equations?
Linear equations are a subset of first order equations. One homogeneous variable of degree one constitutes a linear equation in one variable (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.

How to Solve?
Solving a linear equation involves determining the answer to a linear equation with one, two, three, or more variables. The answer to a linear equation is the value or values of the variable(s) that are part of the equation. There are six main ways to resolve linear equations. For the purpose of solving linear equations, these methods include the Graphical Method, Elimination Method, Substitution Method, Cross Multiplication Method, Matrix Method, and Determinants Method.

Let the greater of the two numbers be "x" and the smaller one be "y".
Given, x - y = 1200 --(i) & x + y = 6484 --(ii)
Adding (i) and (ii), we get, 2x = 7684 ⇒ x = 3842
Subtracting (i) from (ii), we get, 2y = 5284 ⇒ y = 2642
Thus, the greater number of the two numbers is 3842 and the smaller number is 2641.

The opposite of 0 is 0, the opposite of 7 is -7 and the opposite of 6 is -6.

If we consider a number x, then the opposite of the number x will be equal to -x. In a number line the opposite of a number lying on the positive side always lies on the negative side of number line. Also, the opposite of a number -x is the x that is the number itself. It is given in the question that we need to find opposite of 0, 7 and 6.

Let x = 0, opposite of x is -x.

=> -x = -0

=> -x = 0

Now, let x = 7, opposite of x is -x

If Jacob ran 10 miles in 80 minutes at that he will run the distance of 18.75 miles in [tex]2\frac{1}{2}[/tex] hours

Number of miles that Jacob will run in 80 minutes = 10 miles

Number of miles that Jacob will run in 1 minutes = Number of miles that Jacob will run in 80 minutes/ 80

We know,

1 hour = 60 minutes

[tex]2\frac{1}{2}[/tex] hours = 2.5×60

Given equation:

[tex]\textsf{Apply the product law} \quad \ln x + \ln y=\ln xy:[/tex]

Step-by-step explanation:

A Range is all possible values of a certain variable or piece of information commonly notated by a minimum and maximum. In this example, our variable is the speed traveled by drivers in a road. We are provided a minimum of 30 mph as this is the speed limit, and told that drivers may speed up to a maximum of 3 mph faster ( or 33 mph).

Therefore, our minimum would be 30, maximum would be 33, and Range would be [30, 33].

Brackets are used here because both our minimum and maximum values are included in the range.

y = 1.5x - 7            m = 1.5     b = -7

(y = (1.5)x + (-7) ----> y = 1.5x - 7)

y = -1.5x - 4         m = -1.5      b = -4
