1/2 chance per flip
1/2 times 4 is 1/8
its 1/8 chance or 12.5%
1 solution. it can't be 2, and if you solve it, there is a solution, x stays in the equation, so there's 1 solution
The answer is g. 47.1
you use the formula
c= π d
then plug is 15 for d and you should get the answer
No
We know scale factor(k)=y/x
Calculate units as 1 and find k
For left side


Hence its not a copy
