Answer:

30240

Step-by-step explanation:

There are ten possible digits (0 to 9). This means 100000 possible zip codes if repeatable. 540 * 56 = 30240 zip codes without any repetitions.

A bicycle wheel has a diameter of 24inches. <br> what is the area of the wheel?

goldfiish [28.3K]

Answer:

$\large\boxed{A=144\pi\ in^2\approx452.16\ in^2}$

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 24in, then the radius r = (24in) : 2 = 12in.

The formula of an area of a circle:

$A=\pi r^2$

Substitute:

$A=\pi(12)^2=144\pi\ in^2$

$\pi\approx3.14$

Then

$A\approx(144)(3.14)=452.16\ in^2$

Find all values of c such that

klemol [59]

Step-by-step explanation:

c/(c - 5) = 4/(c - 4)

By Cross-multiplying,

We have c(c - 4) = 4(c - 5).

=> c² - 4c = 4c - 20

=> c² - 8c + 20 = 0

Since the discriminant is negative,

there are no real solutions for c.

However, there exist complex solutions for c.

Using the Quadratic Formula,

c = [8 ± √(-16)]/2

=> c = 4 ± √(-4)

=> c = 4 ± 4i or c = 4(1 ± i).
