1. Answer: 24

<u>Step-by-step explanation:</u>

There are 4 cities to choose from. After visiting the 1st city, there are only 3 cities to choose from, etc (see below).

1st city and 2nd city and 3rd city and 4th city

4 x 3 x 2 x 1 = 24

2. Answer: 30,240

<u>Step-by-step explanation:</u>

There are 10 digits to choose from. After choosing the first digit, there are only 9 digits to choose from (because you can't have duplicate digits in the combination) (see below).

1st digit and 2nd digit and 3rd digit and 4th digit and 5th digit

10 x 9 x 8 x 7 x 6 = 30,240

You can set up a proportion.

Let x be the number of pencils needed.

x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)

Analyze the diagram below and complete the instructions that follow.

Flura [38]

This is an isosceles triangle, so both legs are of length 5√2.

Use the Pyth. Thm. to find the length of the hypotenuse. Square 5√2 and double the result: 25(2) = 50; twice 50 is 100. The square of the length of the hyp. is 100, and so the length of the hyp is sqrt(100), or 10 (answer).
