Answer:

117600

Step-by-step explanation:

50 x 49 x 48 = 117,600 ways

You have 50 possible for 1st, 49 for 2nd, 48 for 3rd

or

Permutations 50P3 = 117,600

There are total 59280 ways that can the runners finish first, second and third in a race.

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.

[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]

Where,

[tex]nP_{r}[/tex] is permutation.

n is total number of objects.

r is number of objects selected.

According to the given question

Total number of runners, n = 40

Total number of runners to be selected for first, second and third position  is 3 i.e. r = 3

Therefore,

The number of ways can the runners finish the first, second and third is given by

[tex]40P_{3} = \frac{40!}{((40-3)!} =(40)(39)(38)=59280[/tex]

Hence, there are total 59280 ways that can the runners finish first, second and third in a race.

Step-by-step explanation:

that's all

If 1 share had an initial cost of $0.000007, then 3,000,000 shares would be worth

(3,000,000 shares) × ($0.000007/share) = $21

If the price increases to $0.01 per share, then the same number of shares would have a value of

(3,000,000 shares) × ($0.01/share) = $30,000

So you've gained a net profit of $30,000 - $21 = $29,979, which corresponds to a

$29,979 / $21 = 1,427.57 = 142,757%

increase in value.

Answer: 4.3 × 10^6 meters, and 4.3 × 10^9 millimeters.

Explanation: In order to find the scientific notation of a large number, you want to move the decimal point to the left until you only have one digit to the left of the number, then you can count the spaces you have moved, and this will make the power of 10 that you'll add to the end. This seems a little confusing, but let's look at it through the example.

Step 1) Move the decimal point to the left until there's only one digit to the left of the decimal:

4,300,000 turns into 4.300000

Step 2) Count the number of digits you've moved.

Above, we moved 6 spaces to the left.

Step 3) Add the decimal to the front, and then 10^the number of spaces you moved

4.3 (from step one) × 10^6 (from step two)

= 4.3 × 10^6

It works the same way for the millimeter question, just convert meters into millimeters before you start the problem, and then solve it using the steps above! I hope this helped you :)

The scientific notation in meters and millimeters are

- 4.3 x [tex]10^{6}[/tex] meters

- 4.3 x [tex]10^{9}[/tex] millimeters

It is a way of writing very large or very small numbers where a number between 1 and 10 is multiplied by a power of 10.

Example:

310,000,000 can be written in scientific notation as 3.1 ✕ 10^8.

We have,

Distance = 4,300,000 meters

1 meter = 1000 millimeters

So,

4,300,000 meters = 4,300,000,000 millimeters

We can write 4,300,000 in scientific notation as:

= 4.3 x [tex]10^{6}[/tex] meters

We can write 4,300,000,000 millimeters in scientific notation as:

= 4.3 x [tex]10^{9}[/tex] millimeters

Thus the scientific notation in meters and millimeters are

- 4.3 x [tex]10^{6}[/tex] meters

- 4.3 x [tex]10^{9}[/tex] millimeters

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 204 by 5 and keep only what is to the left of the decimal point:

204 / 5 = 40.8000 = 40

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

204 - (5 x 40) = 4

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 204/5 as a mixed number is:

40

What is 204/6 as a Mixed Number?

Here is the next improper fraction on our list that we converted to a mixed number.

Terminology & Explanation

204 above the division line is called the numerator and 5 below the divison line is called the denominator.

We call the line that separates 204 and 5 the division line. It is also known as the fraction bar or vinculum.

204/5 is an improper fraction because the numerator is greater than the denominator.

A mixed number is an integer (whole number) and a proper fraction.

Answer:

w= -1

Step-by-step explanation:

-1.01 = 1.4(w + 2) - 2.41

add 2.41 to both sides

1.4 = 1.4(w + 2)

divide by 1.4 on both sides

1=w+2

subtract 2 on both sides

-1 =w

The equation that can be used to represent this situation is 8x + 10y = 1600

Let x represent the number of student tickets sold and y represents the number of adult tickets sold.

Since students ticket cost $8 and adult tickets cost $10, and the total ticket sold was $1600, hence this can be represented by the equation:

8x + 10y = 1600
