Answer:
V = 140 pi ft^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 Bh where B is the area of the base
V = 1/3 (35 pi) * 12
V = 4*35 pi
V = 140 pi ft^3
We cannot approximate pi if we want the exact answer
Answer:
The answer would be
Step-by-step explanation:
the common factor i.e. z gets canceled out
Let's start with what we know:
Mary needs at least $50 to pay back her parents
Currently, she has $10, $12, and $25 in her possession. Let's add those values together and see if they equal $50 or more:
10 + 12 + 25
22 + 25 = $47
Since she only has $47, she needs $3 more to pay back her parents.
0= -3x+9
-9=-3x
3=x
Final answer: x=3
There is only one zero because it is linear, and can therefore only cross the x axis once.
