the answer is 12
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
We know that the lowest number on a die is 1 and the lowest number on a card is 2. We can add these two together to find our first sum, 3.
Next, we will add our highest numbers; 6 + 10, which equals 16. Instead of solving for everything in between, since we have found the lowest and the highest and we are only looking for different sums, we can do the following:
16 - 2
You may be wondering why we would do 16 minus two instead of three. This is because three is included as one of the different combinations. The result of this formula is 14, so we know that there are 14 different combinations.
In this question, you're trying to find the unit rate in which the teacher can grade tests.
A unit rate is another word for "rate of change".
This means that we have to find how many tests the teacher could grade in 1 minute.
To find the unit rate, divide 18 by 15
18 ÷ 15 = 1.2
This means that Mr. Rivera can grade 1.2 tests in 1 minute.
Answer:
1.2 tests
