Answer:

y = 108°

Step-by-step explanation:

Since AB and CD are parallel lines, then

3x - 12 and 2x + 16 are corresponding angles and congruent, thus

3x - 12 = 2x + 16 ( subtract 2x from both sides )

x - 12 = 16 ( add 12 to both sides )

x = 28

Thus

3x - 12 = 3(28) - 12 = 84 - 12 = 72°

y and 3x - 12 are adjacent angles and supplementary, thus

y = 180° - 72° = 108°

Please help, i’m so behind on my work :(( image attached
gregori [183]

Answer:

5/8

Step-by-step explanation:

28x + 4 can be factorised because 28 is a multiple of 4

so it can become

4(7x+1)

35x + 5 can be also factorised because 35 is a multiple of 5

5(7x+1)

we can now rewrite the expression as

6/4(7x+1) * 5(7x+1)/12

we can “eliminate” the two 7x+1 and simplify 6 with 12

so it remains

1/4 * 5/2 = 5/8

Misha used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the t
kotykmax [81]

To solve this problem, let us first remember that probability is:

Probability = number of successful events / number of total events

 

Now, let us first calculate the probability of getting a blue marble. There are 20 blue marbles out of 50 total marbles, therefore the probability is:

P (blue marble) = 20 / 50 = 0.4

 

Next, let us calculate for the probability of landing tails up. There are 22 tails success out of 50 times the coin was tossed, therefore the probability is:

P (tails) = 22 / 50 = 0.44

 

Finally, since we want to find the Probability of getting blue and Probability of landing tails, we multiply the two:

P (blue and tails) = 0.4 * 0.44

P (blue and tails) = 0.176               (ANSWER)

 

Now if the choices are in fraction:

P (blue and tails) = (20 / 50) (22 / 50) = 440 / 2500
