Answer:

78,125 ways

Step-by-step explanation:

Since each question has 5 answer options, then each question has 5 ways to answer it, therefore, for each question it would be:

1st question: 5 ways to answer yourself

2nd question: 5 ways to answer yourself

.

.

.

7th question: 5 ways to answer yourself

All the ways would be the total of the multiplication of each question, that is, 5 ^ 7, since there are 7 questions.

5 ^ 7 = 78125

There would be a total of 78,125 ways to answer the exam.

Answer:

5/8 of a mile

Step-by-step explanation:

Let the distance from Post Office to Friend's house =D

7/8 + 5/6 + D =miles - Total distance from Georgia's house to a Friend's house.

42 minutes / 18 minutes per mile =2 1/3 miles - total distance from her house to a friend's house. So, we have:

7/8 + 5/6 + D = 2 1/3, solve for D

[21 + 20] / 24 + D = 2 1/3

41/24 + D = 2 1/3                     subtract 41/24 from both sides

D =2 1/3 - 41/24

D =7/3 - 41/24

D =[56 -41] / 24

D = 15 / 24

D = 5/8 of a mile - the distance between the School and her Friend's house.
