Answer:
1. Each crayon weights 2 grams.
2. John can make 20 birthday cards in 1 hour.
Step-by-step explanation:
1. First we need to convert Kilograms into grams, to do this, we must multiply the # of Kgs by 1000. Then we need to solve for the mass of the crayon.
Each crayon weights 2 grams.
2. First we need to convert 1 hour into minutes. As there are 60 minutes in an hour, we must multiply the number of hours by 60 to find the minutes. Then we can solve for the number of birthday cards.
John can make 20 birthday cards in 1 hour.

You can solve this problem by using the pythagorean theorem.
Where the a- and b-values represent the sides of the triangle. Since the park is a sqaure, each side is equal. This means that both the a-value and the b-value are the same. Now, you must find the c-value.
145^2 + 145^2 = c^2
21,025 + 21,025 = c^2
42,050 = c^2 *now square root each side of the equation.*
205.06 = c
The length of the diagonal line is 205 meters.
