Step-by-step explanation:

PR and QS and parallel lines and QR is a transversal.

Now,

5y = 55 (alternate interior angles)

y = 55/5

y = 11

Answer:

x < -([tex]\frac{11}{2}[/tex])

Step-by-step explanation:

2(4x + 1) < 3(2x - 3)

8x+2 < 6x-9

2x+2 < -9

2x < -11

x < -([tex]\frac{11}{2}[/tex])

Answer:

Step-by-step explanation:

can u pls mark me brainliest?

Answer:

x=12 ft

Step-by-step explanation:

4/5=x/15

Multiply 5 and x to get 5x, then multiply 4 and 15 to get 60, then you're left with the equation 5x=60. Divide both sides of the equation by five to get 12 :D.

Step-by-step explanation:

Solution :

Population proportion, P = 77%

Sample size is given by n = 55

Sample proportion = [tex]$\frac{x}{n} = \frac{34}{55}= 0.61$[/tex]

Null hypothesis

The population proportion of the fatalities of the drivers that are related to alcohol = 77%

[tex]$H_0 : P = 77$[/tex] %

[tex]$H_0 : P = 0.77$[/tex]

Alternate hypothesis, [tex]$H_a : P < 0.77$[/tex]

Therefore, the test statistics = [tex]$\frac{0.61 - 0.77}{\sqrt{\frac{0.7 \times 0.23}{55}}}$[/tex]

                                                = -3.2

Critical value = -1.64

and the rejection zone : test zone, -1.645

Therefore, we fail rejecting [tex]$H_0$[/tex]

p value 0.0582

rejection zone :: p value , 0.01

So we fail to reject [tex]$H_0$[/tex]

Thus the data does not indicate the population proportion of the drivers fatalities which are related to the alcohols which is less than 77% in the county of Kit Carson.

Answer:

Starnes 2.9

Step-by-step explanation:

Answer:

x = 20

4x = 80°

5x = 100°

Step-by-step explanation:

The given angles are supplementary so their sum is 180°

4x + 5x = 180

9x = 180 divide both sides by 9

x = 20

The value of the angle marked 4x = 4 × 20 = 80°

The value of the angle marked 5x = 5 × 20 = 100°

Answer:

80°, 100°

Step-by-step explanation:

The 2 angles are same- side interior angles and are supplementary, thus

4x + 5x = 180

9x = 180 ( divide both sides by 9 )

x = 20

Thus

4x = 4 × 20 = 80°

5x = 5 × 20 = 100°

-1/3 is closer to 0

3/8 is farther from 0

Answer:

6 visits will it take for the costs to be the same

Step-by-step explanation:

The form of the linear relation is y = m x + b, where

Assume that the number of visits is x, and the total cost is y

∵ Alice’s Athletic Arena requires members to pay $20 to join

→ That means there is an initial amount of $20

∴ b = 20

∵ The members must pay $1.50 for each time they come to work out

→ That means there is a cost for every visit (rate of change)

∴ m = 1.5 dollars/visit

∵ The number of visits = x

∵ The total cost is y

→ Form the linear equation for this situation

∴ y = 1.5x + 20 ⇒ (1)

∵ Roy’s Romper Room requires members to pay $5 to join

∴ b = 5

∵ The members must pay $4 for each time they come to work out

∴ m = 4 dollar/visit

→ Form the linear equation for this situation

∴ y = 4x + 5 ⇒ (2)

∵ The costs to both are the same

→ That means, equate the right sides of (1) and (2)

∴ 1.5x + 20 = 4x + 5

→ Subtract 20 from both sides

∴ 1.5x + 20 - 20 = 4x + 5 - 20

∴ 1.5x = 4x - 15

→ Subtract 4x from both sides

∵ 1.5x - 4x = 4x - 4x - 15

∴ -2.5x = -15

→ Divide both sides by -2.5

∴ x = 6

∴ 6 visits will it take for the costs to be the same

Answer: 18x+16 cm

Step-by-step explanation:

Combine the like terms. 9x+9x = 18x and 8+8=16

Answer: The base is 17 meters long, and the height is 12 meters.

Step-by-step explanation:

The area of a triangle is:

A = b*h/2

where:

b = base

h = height.

For this particular triangle, we have that:

b = 5m + h

A = 102 m^2 = b*h/2

We can replace the first equation into the second one:

b*h/2 = 102 m^2

(5m + h)*h/2 = 102 m^2

(5m + h)*h = 2*102 m^2 = 204m^2

5m*h + h^2 = 204m^2

We can rewrite this as a quadratic equation:

h^2 + 5m*h - 204m^2 = 0

The solutions are given by the Bhaskara formula, the solutions are:

[tex]h = \frac{-5m +- \sqrt{(+5m)^2 -4*1*(-204m^2)} }{2*1} = \frac{-5m+-29m}{2}[/tex]

Then the two solutions are:

h = (-5m - 29m)/2 = -17 m

This is a negative height, that is not really defined, so this will be discarded.

The other solution is:

h = (-5m + 29m)/2 = 12m

This is positive, so this is the option we will use.

Knowing h, we can find the value of b.

b = 5m + h = 5m + 12m = 17m

Then the area is:

A = 12m*17m/2 = 102m^2

Answer: The answer is 1.5

Step-by-step explanation: First you want to add 5x + x which equals 6x. Then you want to add -5+-4 which = -9. Then you add 9 to the -9 to get rid of it. But you have to do it on both sides so you add 9+0 which =9. Finally you divide 9 by 6 which equals 1.5

Answer:

  about 9.80 cm

Step-by-step explanation:

The length of half the segment (h) can be found from the Pythagorean theorem:

  h² +5² = 7²

  h² = 7² -5² = 49 -25 = 24

  h = √24 = 2√6

This is half the segment length, so the whole segment length is ...

  L = 2h = 2(2√6)

  L = 4√6 ≈ 9.7980

The length of the segment is 4√6 ≈ 9.80 cm.

Answer:

y = -5/3x + 6  

Step-by-step explanation:

A line parallel to it would have the same slope which is -5/3 so then you can plug in the points you were given and find b for the line parallel which would be 1 = -5/3(-3) + b and that would simplify into 6 = b so then you know your y intercept and you can now plug it in for the new equation y = -5/3 + 6

Answer:

D = 0.5 + 20x + 0.5v

Step-by-step explanation:

Initial distance covered d1 = 0.5km

If she rode a bicycle for x hours at an average speed of 20 kilometers per hour, then her distance during thus period is,;

Speed = Distance/Time

Distance d2 = speed × time

d2 = 20x

If she ran for 0.5 hour at an average speed of v kilometers per hour, her distance this time will be;

Distance d3 = 0.5v

If her total distance is D, then;

D = d1+d2+d3

D = 0.5 + 20x + 0.5v

Hence an equation that relates D, x, and v is D = 0.5 + 20x + 0.5v
