Step 1
Define the variables
Let
x-----> number of erasers
y-----> total cost
we know that
------> this is the linear equation that represent the situation
therefore
the answer is y = 0.84 + (0.38)x
Answer:
150.72 cubic centimeter
Step-by-step explanation:
Given:-
Height of cone (h) = 9cm
Diameter of cone(d)=8cm
radius of cone(r)=
=
To calculate= Volume of cone(
)


Volume of cone(
) 
Therefore paper cone cup can hold 150.72 cubic centimeter of water.
I think C because A and D are Vertically Opposite angles and B is Complimentary angles
