So what you can do is lets say you have to multiply 5/6 by 3 you just make 3 into a mixed number 2 6/6 and multiply it like that.
Surface area of a sphere = 4πr^2
4πr^2=100π
Divide both sides by 4π
r^2=100
r=10
The radius is 10 cm.
Y=-3x+1
So the answer is A. All you're doing is moving the 3x to the opposite side, and because your switching the side, you need to switch the sign. So it's a negative 3x after you solve for y. Solving for y(or any letter) is just getting that letter alone on one side of the equal sign.
Ok if half are female that means 40 than 80 more for each of them because they all produce 80 so 80 times 40 = 3200 your gonna do the same 2 more times because of 3 generations so 3200 times 3 = 9600 in total
Answer: A. You got it! ✔
Step-by-step explanation: All of the others use the "Y" Axis. That's big no-no for this question. Enjoy :)
