Answer:
Step-by-step explanation:
step 1
Find the volume of the cylinder
The volume of the cylinder is equal to
we have
---> the radius is half the diameter
substitute
step 2
Find the volume of the cone
The volume of the cone is equal to
we have
we have
---> the radius is the same that the radius of the cylinder
substitute
step 3
Find the volume of the plastic object
we know that
The volume of the plastic object is equal to the volume of the cylinder minus the volume of the cone
so
assume
The height of an oak tree (which depends on the age of the tree) is 100
Answer:
Below
Step-by-step explanation:
The equations are:
● y = 8x + 5
● -y = -8x + 5 => y = 8x - 5
Both lines have the same slope wich means that they are parallel
-21 is your answer
it is reflected over the x axis, and the point is on 21 no?
Answer:
Step-by-step explanation:
Let the cost of the item is C.
Case I :
first sale is applied
so, the price of item = one third = C - C/3 = 2C/3
Now coupon is applied
so, the price of item = 
= C/2
case II :
First coupon is applied
so, the price of item = C - C/4 = 3C/4
Now sale is applied
the price of item = 
= C/2
So, it does not matter that either coupon is applied first or the sale is applied first the final cost of the item remains same.
