i believe the answer is -3b+21
Answer:
120/97
Step-by-step explanation:
When you're turning a mixed fraction into an improper fraction, you keep the denominator (bottem number) the same, but you times the numerator (top number) by the whole number (non-fraction number/left number)
6 * 20 = 120
Therefore it should be 120/97
This can not be simplified though (if I recall)
Answer:
169π or 530.93
Step-by-step explanation:
The formula for the area of a circle is πr²
Here, the radius is given to be 13.
So, let's just plug it into the formula as r
π x 13²
π x 169
169π
The radius is 169π. If you want to multiply out the π you would get 530.93, which is equivalent of course.
Question, i dont understand what you are asking.
Answer:
1/2
Step-by-step explanation:
The coin is balanced, so if we call p the probability of heads, then p must be equal to 1-p, the probability of tails. Since p = 1-p, then 2p = 1, therefore p = 1/2. As a consecuence, there is a probability of 1/2 that the number of heads obtained is 1, and a probability of 1/2 that the number of heads obtained is 0.
I hope this works for you!
