Which angle has its terminal side in the third quadrant?

Answers

Answer:

7π/6.

Step-by-step explanation:

The range in the third quadrant is  π to 3π/2 ( or π to 1.5π) so its not π/3 or 3π/4.

5π/3 = 1.67π so it's not this one.

7π/6 = 1.167π  so it's this one.

ok so it's simple this is the way i learned it.
     ____
32 |672  first see how many times 32 goes into 6 which is 0 so put a 0 above 6

     _0___
32 |672   now you take the remainder from the last one which is 6 and combine it with the 7 so then you see how many times how many times 32 goes into 67 which is 2 so put a 2 over it.
     _02__
32 |672    next once again take the remainder which is 1 and combine it with the next number which is 2 to make 12 then find out how many times that goes into 32 

you basically do that till you get a number without a remainder and when you run out of numbers just put a decimal and zeros after it

You are making 8 cups of fruit punch for a party. You have bottles of 75% fruit juice and 25% fruit juice. How many cups of each type of juice should you mix together to make 8 cups of 50% fruit juice?How many cups of 75% fruit juice?

How many cups of 25% fruit juice?

Answers

Answer:

4 cups of 75% fruit juice and 4 cups of 25% fruit juice should be mixed.

Step-by-step explanation:

Suppose, the amount of 75% fruit juice is x cups.

As the total amount of fruit punch is 8 cups, so the amount of 25% juice will be:  (8-x) cups.

Given that, the percentage of juice in 8 cups fruit punch is 50%

So, the equation will be.........

0.75x+0.25(8-x)= 0.50(8)\n \n 0.75x+2-0.25x= 4\n \n 0.50x+2=4\n \n 0.50x= 2\n \n x=(2)/(0.50)=4

Thus, the amount of 75% fruit juice is 4 cups

and the amount of 25% fruit juice is (8-4)= 4 cups.

Answers

as is customary with this quantity of questions, I will only provide answers and not detailed solutions
so the general thing you need to find the solutions
mode=most repeated number
mean=average
probabilty=(desired outcomes)/(total possible outcomes)
permutations (how many ways can you pick...) if you have the question
'how many ways can you order 3 blocks' you do
3 possible for first slot
2 possible for second since 1 was in firrst slot
1 possible for last so
number is 3 times 2 times 1=6 ways

so if you did have one like
'if you can pick 3 blocks from a selection of 10 blocks, how many ways can you pickthem (order counts'
so 10 in first slot
9 in second
8 in third so
10 times 9 times 8=720 ways



1. first or 11
2. third or 9/20
3. first or 2/15
4. second or 36
5. first or 1680
6. fourth 8.625
7. fourth or no mode
8. third or 2008
