Eileen makes her own granola using 1 3/4 cups of oats and 2/3 cup of puffed rice. How many cups of granola does she have?

barxatty [35]

Answer:

2 5/12 cups

Step-by-step explanation:

First, turn 1 3/4 into improper fraction:

1 3/4 = 7/4

Next, Find LCG (least common multiple) of 3 and 4

Multiples of 4: 4, 8, 12, 16, 20, 24

Multiples of 3: 3, 6, 9 , 12, 15, 18

Multiply 7/4 by 3 and 2/3 by 4

7/4 x 3 = 21/12

2/3 x 3 = 8/12

Add both fractions

21/12 + 8/12 = 29/12

Reduce 29/12

29/12 = 2 5/12

So Eileen has 2 5/12 cups of granola

Hope this helps ;)

Emily participates in a trivia quiz show. In each round, 20 points are awarded for a correct answer and 10 points are deducted f

kirza4 [7]

Answer:

1. Emily scored 60 points in the first round

2. Emily scored minus 30 points in the second round

3. Emily's final score is 15 points.

Step-by-step explanation:

1. Let's review all the information given to us to answer the questions correctly:

Points awarded for a correct answer = 20

Points deducted for a incorrect answer = 10

2. Let's calculate the score of Emily in the first round:

Score = 7 * 20 - 8 * 10

Score = 140 - 80

Score = 60

Emily scored 60 points in the first round

3. Let's calculate the score of Emily in the second round:

Score = 4 * 20 - 11 * 10

Score = 80 - 110

Score = - 30

Emily scored minus 30 points in the second round

4. Let's calculate the final score of Emily:

Final score = (Score 1st round + Score 2nd round)/2

Final score = (60 + - 30)/2

Final score = (60 - 30)/2 = 30/2 = 15

Emily's final score is 15 points.
