if L is parallel to M, find the value of each missing variable(s)

Answers

Answer:

5. x = 13

6. x = 11; y = 3

Step-by-step explanation:

5. (9x + 2)° = 119° (alternate interior angles are congruent)

[tex] 9x + 2 = 119 [/tex]

Subtract 2 from each side

[tex] 9x + 2 - 2 = 119 - 2 [/tex]

[tex] 9x = 117 [/tex]

Divide both sides by 9

[tex] \frac{9x}{9} = \frac{117}{9} [/tex]

[tex] x = 13 [/tex]

6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)

[tex] 9x + 25 = 13x - 19 [/tex]

Collect like terms

[tex] 9x - 13x = - 25 - 19 [/tex]

[tex] -4x = -44 [/tex]

Divide both sides by -4

[tex] \frac{-4x}{-4} = \frac{-44}{-4} [/tex]

[tex] x = 11 [/tex]

(13x - 19)° + (17y + 5)° = 180° (linear pair)

[tex] 13x - 19 + 17y + 5 = 180 [/tex]

Plug in the value of x and solve for y

[tex] 13(11) - 19 + 17y + 5 = 180 [/tex]

[tex] 143 - 19 + 17y + 5 = 180 [/tex]

Collect like terms

[tex] 129 + 17y = 180 [/tex]

Subtract 129 from both sides

[tex] 129 + 17y - 129 = 180 - 129 [/tex]

[tex] 17y = 51 [/tex]

Divide both sides by 17

[tex] \frac{17y}{17} = \frac{51}{17} [/tex]

[tex] y = 3 [/tex]

A box contains 7 red, 14 yellow, 21 green, 42 blue, and 84 purple marbles. A marble is drawn at random from the box. Find the odds against drawing a purple or yellow marble.


A. 5 to 7


B. 5 to 12


C. 2 to 7

Answers

Answer:

B

Step-by-step explanation:

Here, we are to find the odds against drawing a purple or yellow marble.

Mathematically, the odds against drawing a particular marble color = 1 - the probability of drawing that particular marble color

probability of drawing a purple colored marble = number of purple colored marbles/total number of marbles

= 84/(84 + 42 + 21 + 14 + 7) = 84/168 = 1/2

So the odds against drawing a purple colored marble = 1 - 1/2 = 1/2

The odds against drawing a yellow marble color = 1 - probability of drawing a yellow colored marble

Probability of drawing a yellow colored marble = number of yellow marbles/total number of marbles = 14/168 = 1/12

So the probability of drawing a yellow colored marble or purple colored marble = 1/12 + 1/2 = 7/12

Now, the odds against drawing either of the two = 1 - the probability of drawing either of the 2 = 1 -7/12 = 5/12

or simply put 5 to 12

your cell phone plan cost $24.99 per month plus $0.12 for each text message you send or receive. you have a most $30 to spend on your cell phone bill. what is the maximum number of text messages that you can send or receive next month?

10 points ​

Answers

Answer:

The maximum number of text messages you can send per month would be 41.

Step-by-step explanation:

1. First, you want to create an inequality from the word problem.  You know that $24.99 is a constant, so we won't put any variables next to it.  You also know that each text message is $0.12, so that would need a variable since it can change each month.  You also know that you can spend $30 maximum each month, so that goes on the other side of the inequality.  Your inequality will look like this:  0.12x+24.99≤30 (x is the number of text messages).

2. Second, you want to solve for x.  To do this, subtract 24.99 from each side.  After this, the equation is 0.12x≤5.01

3. Now, divide each side by 0.12.  Now your inequality is x≤41.75.  This represents how many text messages you can send per month without going over 30.

4. Finally, you have to realize that is impossible to send exactly 41.75 text messages.  So, you have to round down to 41 to get an even number of text messages, and that's your answer!

Hope this helps!  Feel free to ask any questions :)

an angle of 60° in 17.3 s. The linear velocity
of the pendulum is 1.32 ft/s. Determine the
length of the pendulum.

Answers

Answer:

  21.81 ft

Step-by-step explanation:

For an arc of measure α and radius r, the arc length is ...

  s = r·α . . . . . . where α is in radians

Then the linear speed is ...

  s' = r·α'

Here the rate of change of arc angle is (π/3)/(17.3) rad/s, so the radius can be found to be ...

  r = s'/α/ = (1.32 ft/s)/((π/3)/17.3 rad/s) = 1.32·3·17.3/π ft

  r ≈ 21.81 ft

The length of the pendulum is about 21.81 feet.
