120x+45y+50z=C
This equation models this situation where C is the total cost
Answer:
Third option
Step-by-step explanation:
By observing the diagram we can see that the diameter of circular base is 6 inches. The diameter will be sued to find the radius.
r = 6/2 = 3 inches
We can also see from the diagram that lateral height denoted by l is 5 in.
We know that the formula for surface area of a cone is given by:

Comparing it with the options we get that the third option is correct ..
I don’t know it to bad………
1. 13/4
2.60
3. in 36 mins (I don't know about this one)
4.<
5. 3/8< 2/3< 19/24
You need to know the value of X to determine whether or not the equation is true.
