Answer:
it will take her 40 seconds to finish the race.
3/8 per minute, would make it 1/8 every 20 seconds. since she only has 2/8 of a mile left to go, 20 seconds +20 seconds = 40 seconds
(if you needed how long it takes her to run the whole race, it's 2 minutes 40 seconds, which would make her the fastest mile runner in the world)

Step-by-step explanation:
The teacher ordered the students in 24 ways.
We have given that the total number of students is 4.
4 students are assigned to give presentations.
We have to find the arrangement of the 4 students.
<h3>What is the arrangement?</h3>
An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)
In a permutation, the order that we arrange the objects n is important.
4 students can be arranged by 4! ways.
Therefore option 3 is correct.
The teacher ordered the students in 24 ways.

Answer:
1.) 5^7 2.) 4^a+b 3.) a^c+d
Step-by-step explanation:
If the exponents are number, you can add the numbers together. Do <u>not</u> add the base numbers. ( Ex: 3 + 4 = 7 )(problem 1)
If the exponents are variables, indicate that you are adding the variables by putting an addition sign between the letters.
