Answer: Robert and Chris can skate 10 miles in 45 minutes.
Step-by-step explanation:
Let's start by finding the unit rate.
Robert and Chris can skate 
of a mile in 1 minute. Now we can multiply both by 45 to see how far the can go in 45 minutes.
45x1=45
The can skate 10 miles in 45 minutes.
Answer: A
Step-by-step explanation:
The fourth choice - 5/104.
In one cube, there are 3 even numbers - 2,4,6. For two cubes, the total probability is 36.
3*3 / 36 = 9/36
For letters, there are five vowels over 26 letters = 5 / 26
Multiply the two probabilities to get the probability of rolling two even numbers and selecting one of the vowels.
9/36 * 5/26 = 5/104
Answer: 80 dollars
Step-by-step explanation:
You can find a percentage with one of two ways.
For hundreds like this, oftentimes it's quicker and more simple to think of it as just 100. The proportion from 100 to 500 is just 5. 16% of 100 is 16. So, multiply 16 * 5. You would get 80.
The second method is you can use 0.16 * 500. It's the more conventional method, and you get 80, like the last method.
The probability is 3/6 (1/2) as there are 3 prime numbers on a dice (2,3,5) and also 3 odd numbers on a dice (1,3,5)
