By ASA or SAS the triangles can be proves congruent.

Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create a similar appearance.

As, from the given figure we can find some equal parts.

First we have two triangles named KOE and LOB

Now, in both triangles

EO = OB  ( given)

<KOE =< LOB (Vertically opposite angle)

Now, we have one side and one angle congruent.

There are two possibilities now either we have another pair of side to make SAS Congruence or we have another angle congruent to make ASA congruence.

So, either KO = OL or

<LBO = <OKE.

1) Let the value of yellow circles = x

Let the value of green butterflies = y

Consider the left string,

3x + y = 15  ----(1)

Consider the right string,

x + 2y = 15 ----(2)

Let us solve the linear equations

(1) *2  => 6x+ 2y = 30 ---(3)

(3) - (2) => 6x+ 2y = 30 - ( x + 2y = 15)

            =>  5x  = 15

            =>   x =  3

Substituting x in (1)

3(3) + y = 15

y = 15- 9

y = 6

The value of yellow circles = 3

The value of green butterflies = 6        

2)  Let the yellow circles = c

Let the green butterflies = b

The linear equations that could be formed are:

Answer:

f(x) = -3x + 4

Step-by-step explanation:

Plug domain into each function and see if it matches any values in the range.

Answer:

7

Step-by-step explanation:

slope = rise/run = (difference in y)/(difference in x)

First, we find a difference in y.

Subtract any two values of y.

For example: 35 - 14 = 21

Now we find the corresponding difference in x.

Now subtract the x values corresponding to those y values in the same order.

-1 in x corresponds to 35 in y.

-4 in x corresponds to 14 in y.

That means your difference in x is the subtraction -1 - (-4) = -1 + 4 = 3

The difference in y is 21.

The difference in x is 3.

slope = (difference in y)/(difference in x) = 21/3 = 7

The number square root of which is 9.2371 is equal to 85.32 and it lies between two integers which are 81 and 100.

What is an integer ?

Integer is the collection of whole numbers and negative numbers. It does not include the fractional part.

It is given that square root of a decimal number is 9.2371 and we have to find out that the number lies between which 2 integers.

We know that the integer 9 is less than 9.2371 , so the square of 9 will be :

9² = 81

And

The square of next integer 10 is equal to 100.

The square of 9.2371 will be equal to :

= (9.2371)²

= 85.32

So , the number is 85.32 and it lies between 2 integers which are 81 and 100.

Therefore , the number square root of which is 9.2371 is equal to 85.32 and it lies between two integers which are 81 and 100.

Answer:

see explanation

Step-by-step explanation:

the equation of a line (linear equation) has slope- intercept form

y = mx + c ( m is the slope (gradient)) and c the y- intercept )

y = 12 + 2x or y = 2x + 12 ← is in slope- intercept form

with gradient m = 2

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

the only graphs in linear form are

y = [tex]\frac{1}{2}[/tex] x and y = 12 - x

the other 2 have an x² term which indicates they are quadratic

The coordinates of the image after 90° about the​ origin is (6, -5)

A 90 degrees rotation denoted by R(90, 0) is a rotation that has the same effect as the 270 degrees counterclockwise of a figure.

The coordinate of the point is given as

(5, 6)

The rotation is given as 90° about the​ origin

So, we have

(x, y) => (y, -x)

Substitute (5, 6) in (x, y) => (y, -x)

So, we have

Answer:

  25 kg

Step-by-step explanation:

The sum of the weights of the small and large sacks is 65 kg. The larger sack weighs 15 kg more. You want the weight of the smaller sack.

Let w represent the weight of the sand in the small sack. Then (w+15) is the weight of the sand in the larger sack. The total weight is 65 kg, so we have ...

  w +(w+15) = 65

Subtracting 15 from both sides gives ...

  2w = 50

  w = 25

The weight of the sand in the small sack is 25 kg.

For 26 rides in a month, a monthly pass should be made, while for rides less than 26 using a one-way ticket will be a cost-effective method

Cost of one way train ticket = $.195

Cost of monthly pass = $50

Monthly pass: It is a prepaid fare card good for one month of limitless travel. This saves cost and time in terms of commuting costs and time of getting the tickets issues

Let x represent the number of rides one takes

Formulating the equation we get:

95% confidence interval for the true population mean watermelon weight. is (69.94, 72.06)

Confidence Interval formula = Mean ± z × Standard deviation/√n

Mean = 71 ounces

Standard deviation = 2.8 ounces

z score = 95% confidence interval = 1.96

Confidence Interval = 71 ± 1.96 × 2.8/√27

= 71 ± 1.96 × 0.5388602512

= 71 ± 1.0561660924

71 - 1.0561660924

Number of oranges = 1×10

= 10  oranges

Number of oranges equal to the number of apples

Number of apples = 10 apples

Number of bananas equal to the twice the number of apples
