There are 18 + 12 total students.
18 are girls and 12 are boys, since the total is 30 students, that's the amount of probable outcomes, and since there are 12 boys, that's the amount of favorable outcomes, thus
12/30 or 0.4, 0.4 * 100 is 40%.
PQS is congruent to RQS
124/2 = 62°
Answer:
13
Step-by-step explanation:
5^2+12^2=169
25+144=169
sqrt 169 =13
For this case what you must do is to determine the value of r of the given equation:
A = pi * r ^ 2.
Clearing the value of r we have:
r = root (A / pi)
Note that r has two roots:
r1: = + root (A / pi)
r2: = - root (A / pi)
In this case we must ignore the negative root.
Answer:
The formula to find r is
r = root (A / pi)
