Answer:
The numbers of tickets in advanced sold was 260 and the numbers of tickets at the door sold was 65
Step-by-step explanation:
Let
x ---> the numbers of tickets in advanced sold
y ---> the numbers of tickets at the door sold
we know that
325 tickets are sold
so
----> equation A
$1430 is collected
so
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (260,65)
see the attached figure
therefore
The numbers of tickets in advanced sold was 260 and the numbers of tickets at the door sold was 65
A^2 + b^2 = c^2
4^2 + b^2 = 5^2
16 + b^2 = 25. -16
B^2 = 9
Square root of 9 = 3
B = 3
The other leg is 3cm
Answer:
After the markdown, the cost will be $21.35
Step-by-step explanation:
This is shown by multiplying the original price, 30.50 by 30%, or 0.30 to get 9.15. Next you subject your product from the original price to get the marked down value at 21.35.
Answer:
6x + 4 - 1/100 = 77.5
Step-by-step explanation:
Inc shipping all shirts 77.49
Shirt individual cost = 12.25
We find the division first = 77.49-3.99 = 73.5 = 73 1/2
Then we divide 73.5 / 12.25 = 6
Then we have our equation
6x + 4 - 1/100 = 77.5
Circumference of a circle - derivation
This page describes how to derive the formula for the circumference of a circle.
Recall that the definition of pi (π) is the circumference c of any circle divided by its diameter d. Put as an equation, pi is defined as
π
=
c
d
Rearranging this to solve for c we get
c
=
π
d
The diameter of a circle is twice its radius, so substituting 2r for d
c
=
2
π
r
If you know the area
Recall that the area of a circle is given by
area
=
π
r
2
Solving this for r
r
2
=
a
π
So
r
=

a
π
The circumference c of a circle is
c
=
