We have the following system:
Here, a simple solution to find the answer is to graph the two lines and see how many times they intersect.
I've attached a graph, with in red and the other equation in blue.
See that the lines only intersect once, at . This means the system only has one solution.
Step-by-step explanation:
??????????????????????
49/80 is greater than 60% because
if you divide 49 by 80 it is 0.6125 and if you divide 60 by 100 it is 0.6
i can only help you with the volume of #5.
So the volume of a cylinder is = πr²h.
First , put the numbers in the equation.
π(6)² (14)
Next you solve.
π(6)²(14) = 36 (14) π = 504π
V= 504π
