Shelly biked 21 miles in 4 hours. Shellys average speed per hour is 5.25. At the same rate how many hours will it take her to ride 42 miles.

Answers

Answer 1

Answer: 42=5.25x
8=x
It will take her 8 hours

Answer 2

Answer: shelly biked = 21 miles / 4 hours
Shelly's average speed = 5.25 miles / hour
distance to be travelled = 42 miles
Time that would be taken = ?
we know that speed= distance / time
5.25 = 42/time
or time = 42/5.25
time = 8 hours 《《 ANSWER

You roll a pair of fair six-sided dice. The sample space of 36 possible outcomes is shown below. Based on this information, answer the following questions.

Answers

Answer:

All the 36 outcomes are equally likely.

Step-by-step explanation:

The sample space of rolling a single six-sided dice is:

S = {1, 2, 3, 4, 5, 6}

Then the sample space of rolling a pair of six-sided dice is:

S₁ = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)

(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)

(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)

(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)

(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)

(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

All the 36 outcomes are equally likely, i.e. all the outcomes has the same probability of success, $(1)/(36)$ .

The expression 1/2 times(4+8) represent the number of hours Mrs nakos work that last week of school.evaluate the expression to find the number of hours she works that week

Answers

The expression $(1)/(2) * (4 + 8)$ represents the number of hours Mrs. Nakos worked during the last week of school. When expression evaluated, it equals 6 hours. So, Mrs. Nakos worked 6 hours that week.

To find the number of hours Mrs. Nakos worked during the last week of school, you can evaluate the expression $(1)/(2) * (4 + 8)$ step by step:

1. Start by evaluating the expression inside the parentheses:

$4 + 8 = 12$

2. Now, you have the expression $$ (1)/(2) * 12 $.$ To calculate this, multiply 12 by
$(1)/(2)$ since dividing by 2 is the same as multiplying by $$ (1)/(2) $:$
$(1)/(2) * 12 = 6$

So, Mrs. Nakos worked 6 hours during the last week of school.

The expression $(1)/(2) * (4 + 8)$ represents the number of hours worked, and when evaluated, it equals 6 hours. Therefore, Mrs. Nakos worked 6 hours that week.
