A road has a 10% grade (slope).how much does it rise if it is 2 km long?
10% = 1/10
So, it rises 1/10 as far as it runs horizontally: .2km or 200m
an eight sided number cube has the numbers 1,2,3,4,5,6,7 and 8 on it. the number cube is thrown once. What is the probability of 2?

To determine how much the road rises over a 2 km distance with a 10% grade, you can follow these steps:
Step 1: Convert the grade percentage to a decimal. Divide the percentage value by 100. In this case, the grade is 10%, so you divide 10 by 100, which equals 0.1.
Step 2: Multiply the grade percentage (in decimal form) by the length of the road. Multiply 0.1 by 2 km, which equals 0.2 km.
Therefore, the road rises 0.2 km (or 200 meters) over a 2 km distance with a 10% grade.
