Answer:
Step-by-step explanation:
As a result of the pythagorean theorem we can say that a^2+b^2=c^2
In this case, we have bc and ab missing side ac. So the equation looks something like this
dont get confused by the ac in the problem i only wrote it like that because ac is the length representation. So 16+ac^2=121 and with algebra we can solve to ac^2=105 or side ac=
1/2
it is a 50/50 chance getting heads
Answer:
The second, third, and fourth answers
Step-by-step explanation:
Answer:
C) 6 to 5
Step-by-step explanation:
if there is 6 new books there is 5 used books (11 - 6 = 5)
so new to used is 6 to 5
4X + 7X = 33
11X = 33
X =3
So, 4*3 = 12, and 7*3= 21
