What is the radius, in centimeters, of a circle that has a circumference of 16π?

8
16
32
64

Answers

Answer: The radius equals 8cm

Answer:

8

Step-by-step explanation:

The circumference of a circle is equal to  π , which is a number  ≈ 3.14 , multiplied by the diameter of the circle.

Therefore,  C  =  π d .

We know that the circumference,  C , is  16 π , so we can say that:

16 π  =  π d

We can divide both sides by  π  to see that  16  =  d .

We now know that the diameter of the circle is  16 .

We also know that the diameter has twice the length of the radius.

In equation form:  2 r  =  d

2 r  =  16

r  =  8

Note that since  2 r  =  d , the equation  C  =  2 π r  holds and can be used in place of C  =  π d .

Liz flips a coin 90 times. The coin lands head up 63 times and tails up 27 times. The theoretical probability of the coin landing heads up is ___​%.

Answers

Answer:

50%

Step-by-step explanation:

This question asks for the theoretical probability

In order to find theoretical probability, we find how many outcomes are possible, and how likely each action is.

In this case, we are flipping a coin. There are only two possible outcomes of this, which are heads and tails. Each of these are equally likely, so that would mean the theoretical probability of flipping it and it landing heads up is 50%

Answer:

P(head up) = 70%

Explanation:

P(head up) = 63/90

P(head up) = 7/10

P(head up) = 70%

You are stuck in a big traffic jam on the freeway and you are wondering how long it will take to get to the next exit, which is 1 1/2 miles away. You are timing your progress and find that you can travel 2/3 of a mile in one hour. If you continue to make progress at this rate, how long will it be until you reach the exit? Solve the problem with a diagram and explain your answer.

Answers

Answer:

2.25 hours

Step-by-step explanation:

Because 2/3 as a decimal is 0.66666666666 and of course 1 1/2 miles is 1.5, so you divide 1.5 by 0.66666666666 and then round it to the nearest hundreth. So there you go, hope this helped :)

Rather than combusting hydrogen in the presence of oxygen, the overall reaction (1/2) O2 H2 H2O is actually carried out as two `half-reactions occurring at separate electrodes. To complete the reaction, this forces electrons to pass through an external circuit from one electrode to the other, and this current can be used to do work; e.g., by driving a motor. Typical operating conditions for a solid-oxide fuel cell are 500-900 C and 5-15 bar. Consider a fuel cell in which a pure oxygen stream and a pure hydrogen stream enter at 11 bar and 700 C with stoichiometric flowrates. Assume that these reactants are consumed completely, and that the water generated by the reaction leaves in a third stream at the same T and P. Assume that the fuel cell operates at steady-state with a uniform temperature of 700 C. a) Write simplified first and Give two examples of pioneer species. 3.What is Shirley Chisholm's overall purpose in her speech?A. to discredit the other candidates running for the Democratic nominationB. to persuade people that she is the right choice for the Democratic nominationC. to convince people that she has overwhelming support for the DemocraticnominationD. to pressure people to vote for her for the Democratic nomination A shipment of sugar fills 8 containers.
