A gumball machine has different flavors sour apple,grape,orange and cherry . There are six of each flavor. $.50 are put in the m

tamaranim1 [39]

Answer:

30/552

Step-by-step explanation:

In order to solve this problem you need to multiply the probability of getting grape for the first gumball with the probability of getting grape for the second gumball. Since there are 6 grape gumballs and a total of 24 gumballs (6*4). Then the probability of getting grape for the firs one is

$\frac{6}{24}$

Now there are only 5 grape gumballs available and one less in the total supply, therefore the probability of getting grape in the second try is

$\frac{5}{23}$

Finally we multiply them together to find the probability of getting two grapes in a row.

$\frac{6*5}{24*23}$ = $\frac{30}{552}$

If 2xº and (2x - 20) are a pair of adjacent supplementary angles, find the value of x.

kifflom [539]

Answer:

x = 50

Step-by-step explanation:

Since the two angles are supplementary, add them together and set them equal to 180 degrees

2x + 2x - 20 = 180 Combine like terms

4x - 20 = 180

+ 20 + 20 Add 20 to both sides

4x = 200 Divide both sides by 4

x = 50

Hey! Can someone please answer this?

Lelechka [254]

This picture should provide a full answer. What I did was rearrange the equation to get Tan(x) on one side, then in order to get rid of the Tan, I used Arctan, which got us the final answer.
