Answer:

The answer is 100 is four times as large as 25

Step-by-step explanation:

Division compares numbers by telling you how many times larger the first number is then the second number. In this problem, 100/25=4.

Put another way, 25 x 4 = 100. Therefore,100 is four times as large as 25

How many ways can 8 books be arranged on a shelf? Show all of your work for full credit.

Talja [164]

<h3>Answer:</h3>

There are 40,320 ways, in which 8 books can be arranged on a shelf.

<h3>Solution:</h3>

Here, we are to find the number of ways in which 8 books can be arranged on a shelf. The total number of books is 8 and the way of arranging books is also 8.

If one book is placed in the first place, then 7 books will be placed in front of it. If 2 books are placed in the 2nd place, then only 6 books can be placed after that book. This sequence will continue till 1 .

<u>Permutations </u><u>:</u>

A permutation is an arrangement of objects in a definite order.

➲<u> P ( n, r )= n ! / ( n - r ) !</u>

n = total number of objects

r = number of objects selected

The number of ways to arrange 8 books on a shelf will be :

➝ P ( n, r ) = n ! / ( n - r ) !

➝ P ( n, r ) = 8 ! / ( 8 - 8 ) !

➝ P ( n, r ) = 8 ! / 0 !

➝ P ( n, r ) = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 / 1

➝ P ( n, r ) = 40, 320

‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ~ Hence, there are <u>40,320 ways</u> in which 8 books can be arranged on a shelf !

trapecia [35]

Answer:

(a) 3118=61*t

(b) The amount of time the roller coaster is in motion is 51.11 seconds.

Step-by-step explanation:

Speed is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, speed is associated with the change in position of a body over time and can be expressed as:

$speed=\frac{distance}{time}$

Then the distance traveled can be expressed as:

distance=speed*time

(a) If x represents the total time that the roller coaster is in motion for each ride, the average speed is 61 feet per second and the distance is 3118 feet then the expression to represent the situation is:

(b) To calculate the amount of time the roller coaster is moving, you simply need to solve the expression found in (a). Dividing 61 to both sides:

$\frac{3118}{61} =\frac{61*x}{61}$

51.11 seconds=x

<u><em> The amount of time the roller coaster is in motion is 51.11 seconds.</em></u>
