Subtract a number from the next number.
39 - 45 = -6
Answer: B. -6
Radius = 1.25cm
81cm3 / 20 = 4.05 cm3 per cone
V cone = πr^2 (h/3)
So then 4.05 = π(1.25)^2 (h/3)
Then h/3 = .825 and then
h = 2.475 cm
Part A).
If 100 fish all had the same weight, and they weighed
235 pounds when they were all on the scale at the
same time, then each fish weighed
235 / 100 pounds .
Part-B).
You can find that actual weight with your calculator.
235 / 100 = 2.35 pounds .
Part-C).
If there were only 10 fish but their total weight was still 235 pounds,
then each fish would have to weigh a lot more, to make up the same
weight with only 10 of them.
Now, each fish would have to weigh 235 / 10 pounds .
That number is 235/10 = 23.5 pounds.
If there were only 1/10 as many fish, then in order to add up to the
same total weight, each fish would have to be 10 times as heavy.
Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:
How many times does the line y=-6 intersect with the circle?
We have to find the values of x when 
So
Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.
The given equation is an equation of a circle because it looks similar to the general equation of a circle.
<h3>What is the general equation of a circle?</h3>
The general equation of a circle is:
x² + y² +2gx + 2fy + c = 0...........eq1
Where (-g, -f) is the center of the circle.
c is a constant
Given equation is
3x² +6x + 3y²+7y+4 = 0
Let us take 3 as common
x² + 2x+y²+7/3y + 4/3 = 0
Let us rearrange the equation
x² + y²+2x +7/3y + 4/3 = 0...........eq2
Now look at eq1 and eq2
We got that eq2 is having a similar pattern as eq1.
Therefore, The given equation is an equation of a circle.
