Which expression converts 45° to radians?

Mathematics
1 answer:
eimsori [14]3 years ago
6 0

Answer:

pi/180°

Step-by-step explanation:

A full circle of 360 degrees is 2 pi radians.

Dividing by 2, 180 degree is pi radians.

180 degrees = pi radians

Divide both sides of the above equation by 180 degrees.

(180 degrees)/(180 degrees) = (pi radians)/(180 degrees)

1 = pi/180°

Since pi/180° equals 1, you can multiply it by a number an not change the value of a number just like 1 time 5 is still 5.

45° * (pi/180°) will convert 45 degrees to radians.

Answer: pi/180°

I need to know what this answer is<br><br><br>3. Write the expression 175 using radicals. ​
Rus_ich [418]

Answer:

5√7

Step-by-step explanation:

What we want to do is first just put the 175 in a sqrt like this:

√175

Next we do prime factorisation to try and simplify further.

         175

      /          \

   25            7

  /     \

5         5

We can figure out that this out √5^2 times 7

we can cancel the sqrt and the squared and simplify to 5√7

So there is your answer, 5√7.

If you have any questions feel free to ask. Also for the prime factorisation the formatting may be off, sorry for the inconvenience and have a good day!

PLS HELP!!!!!! 55 points!!!!!! Create an experiment about the probabilities associated with choosing a candidate for class presi
NemiM [27]

(How to find) Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

(How to solve) Theoretical probability is a method to express the likelihood that something will occur. It is calculated by dividing the number of favorable outcomes by the total possible outcomes. The result is a ratio that can be expressed as a fraction (like 2/5), or a decimal

(How to experiment) Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

(Example) The theoretical probability of an event occurring is an "expected" probability based upon knowledge of the situation. It is the number of favorable outcomes to the number of possible outcomes. Example: Find the probability of rolling a 6 on a fair die.
