This is the concept of volumes of solid materials, to get the amount of wax needed to make the candle we will require to calculate for the volume of the candle.
volume=πr^2h
since we are given the circumference of the candle we need to get the radius first;
C=πd
C=31.416 cm
31.416=πd
d=31.416/π
d=10.0000 cm
Therefore the radius will be 5 cm.
The volume of the wax required to make the candle will be:
V=πr^2h
V=π*5^2*13
V=1,021.02 cm^3
Answer:
(5, 8)
Step-by-step explanation:
A solution to a system of linear inequalities is a point that, when its x and y values are substituted into both inequalities, makes <u>both</u> of them true. (Knowing this, if a point makes one inequality true but not the other, it is not a solution to that specific system of linear inequalities.)
So, let's plug in the x and y values of (5, 8) into the inequality y > 3x - 7 and solve like so:
However, 8 is equal to 8, not greater than it. So, we know that this point is not a solution to this inequality since it does not make it true, therefore (5, 8) is not a solution to the whole system.
Hope this helps!
Answer:A composite number is divisible by at least three numbers. Every counting number except 1 is either prime or composite. The reason 1 is neither is that it's divisible by only one number, which is 1. Remember the first four prime numbers: 2, 3, 5, and 7.

Answer:
Step-by-step explanation:
In parallelogram, diagonals bisect each other
DP = IP
7x - 8 = 3x
7x = 3x + 8
7x - 3x = 8
4x = 8
x = 8/4
x = 2
NP = YP
3y = 7x - 2
3y = 7*2 - 2
3y = 14 - 2
3y = 12
y = 12/3
y = 4
