Given the figure below, find the values of x and z.

Answers

Answer: x = 2 and z=78

Step-by-step explanation:

Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure). Z is Opposite to 78 angle, so z=78.

Adjacent angles add up to 180 degrees, and 78 and (5x + 92) are adyacents so:

5x + 92 + 78 = 180

5x + 170 = 180

5x = 180 - 170

5x = 10

x = 10/5

x = 2

Circle J is inscribed in isosceles trapezoid ABCD, as shown. Points E, F, G, and H are points of tangency. The length of AB is 10 cm. The length of DC is 20 cm. What is the length, in cm, of BC?

Answers

Answer:

15cm

Step-by-step explanation:

Theorem: All tangents to a circle from the same point are equal.

Sine E, F, G and H are points of Tangency, by the theorem above:

EB=BFFC=GC

The diameter line EC divides the Isosceles Trapezoid into two equal parts.

Therefore:

EB=10/2=5cmGC=20/2=10cm

We then have by the equality above that:

BF=5cmFC=10cm

BC=BF+FC

=5+10

=15cm

Pablo guarda en su cajon 2 pares de medias blancas 4 pares de medias de azules y tres pares de medias negras cual es la probabilidad de que saque medias un par azul si saca las medias sin ver

Answers

Answer:

44.4%

Step-by-step explanation:

The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:

We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.

therefore the probability is:

4/9 = 0.444

Which means that there is a 44.4% chance of drawing a blue pair.

PLS HELP!!!!! WILL MARK BRAINLIEST Jake is moving. He rented the following moving truck. All the boxes that he has are the same size. He wants to determine the maximum number of cube shaped boxes he can fit in the moving truck. Show all calculations and label all work.

Answers

Answer:

He can fit 53 boxes in the moving truck.

Step-by-step explanation:

Dimensions of the container of truck = 15 feet × 7.5 feet × 7.5 feet

The volume of the container of moving truck = Length × width × height

= 15 × 7.5 × 7.5

= 843.75 feet³

Sides of each small square box = 2.50 feet

Volume of the one box = 2.5 × 2.5 × 2.5

                               = 15.63 feet ³

Maximum number of cube shaped boxes he can fit in the moving truck

= [tex]\frac{843.75}{15.63}[/tex]

= 53.98

What is the equation of a line that passes thorough the point (9,-3) and is parallel yo the line whose equation is 2x-3y=6?

Answers

Answer:

y+3=2/3(x-9)

Step-by-step explanation:

2x-3y=6

-3y=-2x+6

y=2/3x-2

This means that any line parallel to it must have a slope of 2/3 as well. Therefore, the equation of this line, in point slope form, is:

y+3=2/3(x-9)

Hope this helps!

Answer:

y = 2/3 - 9

Step-by-step explanation:

1. rearrange the equation

-3y = -2x + 6

y = 2/3 - 2

2. because it is parallel, the gradient will be the same.  substitute into y - y1 = m(x-x1)

y - (-3) = 2/3 (x - 9)

y + 3 = 2/3 - 6

y = 2/3 - 9

Which of the following functions are linear?

y 8 16 24 32 40

A. Function A
B. Function B
C. Function A and Function B
D. None of the above

Answers

Answer:

answer B is the right answer.

Step-by-step explanation:

Function A has the form of y = x² , which is NOT linear but quadratic.

Function B has the form of y = 8/5x which is linear.

So answer B is the right answer .

The function which is linear is Function B which is f ( x ) = ( 8/5 )x

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

Function B

x 5 10 15 20 25

y 8 16 24 32 40

So , for every increase of 5 in x, y increases by 8, which can be written as the equation y = (8/5)x.

f ( x ) = ( 8/5 )x

Hence , the linear function is f ( x ) = ( 8/5 )x

The sum of the numerator and the denominator of the certain fraction is equal to 4,140. When the fraction was reduced, the result was 7 13 . What was the original fraction?

Answers

Answer:

1449/2691

Step-by-step explanation:

We must start from the fraction that is 7/13. Now, we know that it was simplified, with trial and error we can reach the result.

First, let's multiply both by 200:

7 * 200 = 1400

13 * 200 = 2600

1400 + 2600 = 4000

It means that we are missing 140, to reach the objective, that is, we are close, let's try 205 now:

7 * 205 = 1435

13 * 205 = 2665

1435 + 2665 = 4100

We get even closer, only 40 missing, let's try 207 below:

7 * 205 = 1449

13 * 205 = 2691

1449 + 2691 = 4140

We managed to get to the corresponding numbers, therefore the original fraction was 1449/2691
