You cut a circular hole 1/4 -inch in diameter in a piece of cardboard. With the cardboard 30 inches from your face, the Moon fit

Stolb23 [73]

Answer:

The Moon's diameter is greater than $1,500$ miles

Step-by-step explanation:

we know that

$1\ mile=63,360\ inches$

$1,500\ miles=1,500*63,360=95,040,000\ inches$

$240,000\ miles=240,000*63,360=15,206,400,000\ inches$

by proportion

Find the Moon's diameter

Let

x-----> the Moon's diameter in inches

$\frac{x}{15,206,400,000}=\frac{0.25}{30}\\ \\x= 15,206,400,000*0.25/30\\ \\x=126,720,000\ inches$

Compare

$126,720,000\ inches> 95,040,000\ inches$

therefore

The Moon's diameter is greater than $1,500$ miles

In a group of eighteen people, each person shakes hands once with each other person in the group. How many handshakes will occur

miv72 [106K]

The number of handshakes that will occur in a group of eighteen people if each person shakes hands once with each other person in the group is 153 handshakes

In order to determine the number of handshakes that will occur among 18 people, that is, the number of ways we can choose 2 persons from 18 people.

∴ The number of handshakes = $^{18}C_{2}$

$^{18}C_{2} = \frac{18!}{(18-2)!2!}$

$^{18}C_{2} = \frac{18!}{16!2!}$

$^{18}C_{2} = \frac{18\times17\times16!}{16!\times2!}$

$^{18}C_{2} = \frac{18\times17}{2\times1}$

$^{18}C_{2} = \frac{306}{2}$

$^{18}C_{2} = 153$

∴ The number of handshakes = 153 handshakes

Hence. 153 handshakes will occur in a group of eighteen people if each person shakes hands once with each other person in the group.

Which of the following is the solution to the equation - n/2 + 14 = 0 ?

poizon [28]

The answer is n=28;

1. Subtract 14 from both sides (-n/2 = -14)

2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)

3. Divide by -1 to get n by itself (n = 28)

You could also eliminate step three by multiplying by -2 instead of just 2.

Hope this helps!
