Answer:

It would take Brennan 4 track practice runs.

Step-by-step explanation:

He has already run 16 miles and needs to run 28 in total. If we are counting the 16 in the 28 miles, he would need to run only 12 more to reach his goal. And if he runs 3 miles a run, it would take him about 4 runs to finish his 28-mile goal.

(28-16=12 and 12/3=4)

How many three letter permutations can be formed from the first five letters of the alphabet?
Vsevolod [243]

Answer:

There are 60 permutations that can be formed from the first five letters of the alphabet.

Step-by-step explanation:

The number of three letter permutations that can be formed from the first five letters of the alphabet is 5P_{3}.

5P_{3} =\frac{5!}{(5-3)!}

=\frac{5!}{2!}

= 60

Hence, there are 60 permutations that can be formed from the first five letters of the alphabet.

What is the total cost if the shirt cost $40 and 20% off
Eddi Din [679]
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.

40 × 0.20 = 8

So now you would subtract 8 from the cost of 40.

 40 - 8 = 32.

The shirt costs $32.

How would you solve this problem using the order of operations?<br> 8+(5)(4)-(6+10÷2)+55
vovikov84 [41]

Answer:

72

Step-by-step explanation:

Use PEMDAS

Parentheses

Exponent

Multiplication and Division (if it contains both, just go from left to right)

Addition and Subtraction (if it contains both, just go from left to right)

8 + (5)(4) − (6 + 10/2) + 55

8 + 20 − (6 + 10/2) + 55

28 − (6 + 10/2) + 55

28 − (6 + 5) + 55

28 − 11 + 55

17 + 55

72

To solve it step by step with PEMDAS:

Solve within the parentheses

6 + 10/2

10/2 = 5

6 + 5 = 11

Multiply/Divide

(5)(4) = 20

Add/Subtract

8 + 20 - 11 + 55 = 72
