Answer:
Step-by-step explanation:
The volume of a cone is given by the following equation:
where 
is the volume of the cone, 
is the radius of the base, and 
is the height of the cone.
In the given problem, we know that 
and 
. Using this, we can find the volume of a single cone:
Since the problem asks how much foam is needed to make 120 cones, we can multiply this result to get our answer:
Answer:
when b=2 , a = -4.2
when b=1.5 , b=-2.5
Step-by-step explanation:
When b = 1.5
When b = 2
Collect like terms and simplify
$3 and $5
Explain:im not good at explaining but that should be the answer
Answer:
Step-by-step explanation:
we know that
The sum of interior angles in a triangle must be equal to 180 degrees
so
solve for x
neverminding the dots or points on the line, we can see that the line is using a solid stroke, is a solid line, as opposed to a dashed one.
A solid line means, "the borderline is included in the inequality", so that means either ⩾ or ⩽, depending on how you'd write the expression.
so we can say
y ⩽ "some expression in x-terms here"
or we can say
"some expression in x-terms here" ⩾ y
basically the same thing.
the cat is red
and
red is the cat
same thing, depends on how you write it.
