Answer 1

Answer:

x = 43.5°

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the angles and equate to 360

x + x + 72 + 111 + 90= 360

2x + 273° = 360° ( subtract 273° from both sides )

2x = 87° ( divide both sides by 2 )

x = 43.5°

Answer 2

Answer:

Sum of the angles around a given point is 360°.

[tex]x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = \frac{87}{2} \\ \boxed{x = 43.5°}✓[/tex]

★ x=43.5° is the right answer.

Read Bagheera’s words in this passage from The Jungle Book.

"O Akela, and ye, the Free People," he purred, "I have no right in your assembly; but the Law of the Jungle says that if there is a doubt which is not a killing matter in regard to a new cub, the life of that cub may be bought at a price. And the Law does not say who may or may not pay that price. Am I right?"

"Good! Good!" said the young wolves, who are always hungry. "Listen to Bagheera. The cub can be bought for a price. It is the Law." . . .

"To kill a naked cub is a shame. Besides, he may make better sport for you when he is grown. Baloo has spoken in his behalf. Now to Baloo's word I will add one bull, and a fat one, newly killed, not half a mile from here, if ye will accept the man's cub according to the Law. Is it difficult?"

A. There are 300 fish in a pond. 50 fish are tagged. If you catch one fish out of the pond, what is the probability that your fish is tagged? Write your answer in a fraction and a decimal. Explain and show your work.


B. Suppose you catch 100 fish out of this pond. How many of these fish would you expect to be tagged? Explain.

Answers

Answer:

B. 50

Step-by-step explanation:

Answer:

The probability is 16.6%

And if you catch 100 fish, you should expect at least 17 of them are tagged.

Step-by-step explanation:

Let A be the event of catching a tagged fish:

[tex]P(A) = \frac{50}{300} = \frac{1}{6} = 0.166[/tex]

Now if you catch 100 fish, each one has the probability of 1/6 and each event is independent of the other.

[tex]N = \frac{1}{6} * 100 = 16.6[/tex]

how fast does the squirrel run? if you help me ill mark you brainliest​

Answers

Answer:

The squirrel runs 11 miles per hour.

Explanation:

Speed can be found from the the slope of the graph of distance over time. From this graph the easiest point to calculate this on is the two endpoints. Slope is rise/run. In this graph Y has increases by 11 miles (rise) at the point where time has increased by one hour (run). So the speed can be found with 11 miles/ 1 hour which equals 11 miles per hour.
