Answer:
1289.8089172
Step-by-step explanation:
if you do 90 x 2 = 180 you get the circumference of what would be the complete circle, the formula for area with circumference is A = (C^2/4x3.14) so inserting 180, the answer is 2579.61783439, and half of that is a semi circle so 2579.61783439/2 = 1289.8089172
27 minuets
3/5 of 45 = 27
4/5 of a minuet = 48
18 X 1.48 = 26.64
ROUND = 27
Answer:
No solution
Step-by-step explanation:
(√(2x+3))^2 =(√(2x+33))^2
2x+3 = 2x+33
Answer:
21 cuz it ✅ and if don't think it i don't known what it is
Answer:

Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:

Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:

And now we can find
using the total probability rul given by:

And if we replace the values given we got:

And that would be the final answer.
