E=9h+1.5(9)(h-40)
e=9h+13.5(h-40), since h=49
e=9(40)+13.5(9)
e=9(40+13.5)
e=9(53.5)
e=$481.50
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
Answer:
171
Step-by-step explanation:
The surface area of a sphere is given by

where r represents the radius.
As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.
