Answer:
49
Step-by-step explanation:
1 is incorrect. to solve for f, you have to get it alone, and right now you have a negative sign in your way.
you can eliminate the negative by dividing both sides by -1:
-f = -100
divide by -1 to cancel out the - in front of f
f = 100
Answer:
0.527
Step-by-step explanation:
Divide 6 by 27 and that will get you to a long number like 0.2222222222 but we can shorten it to 0.222. After this you will divide 11 by 36 leading you to the answer of 0.3055555556 which again will shorten to 0.305. Add both of these solutions together and you will get 0.527 as your answer!
Answer:
He needs 7/24 cup of milk
Step-by-step explanation:
If he needs 5/8 cup of milk and has 1/3 cup, he will need to subtract so see how much more he needs.
5/8 - 1/3
We need to get a common denominator of 24
5/8 * 3/3 - 1/3 *8/8
15/24 - 8/24
7/24
He needs 7/24 cup of milk
Answer:
0.71
Step-by-step explanation:
When a coin is tossed 100 times, it yields heads 71 times and tails 29 times.
So the probability of heads = Number of heads/Total number of tosses
= ![\[\frac{71}{100}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B71%7D%7B100%7D%5C%5D)
= ![\[0.71\]](https://tex.z-dn.net/?f=%5C%5B0.71%5C%5D)
Similarly, probability of tails = Number of tails/Total number of tosses
= ![\[\frac{29}{100}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B29%7D%7B100%7D%5C%5D)
= ![\[0.29\]](https://tex.z-dn.net/?f=%5C%5B0.29%5C%5D)
So the probability that the next flip results in a head = Probability of heads in the toss = 0.71
