Answer:

24

Step-by-step explanation:

Factorial is applicable only for natural numbers and 0.

0! =1 trivially.

FOr other numbers, factorial is defined as 1x2x...n

For example 1! = 1

2! = 1x2 = 2

and so on.

i.e. n! = product of all natural numbers from 1 to n

= 1x2x....n

Using the above

we have n =4

Natural numbers from 1 to 4 are 1,2,3,4

Find the product of these 4 natural numbers to get 4!

4! = 1x2x3x4 = 24

Answer:

She should invest 6976.74 $ principal on daughter's 12th birthday.

Explanation:

  We have  I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.

Here p + I = 12,000 $

   So, I = 12000-p

 Interest rate r = 12% =0.12

 Number of years = 18 - 12 = 6 years.

Substituting

   12000-p = p x 0.12 x 6

  p + 0.72 p = 12000

  1.72 p = 12000

   p = 6976.74 $

So, she should invest 6976.74 $ principal on daughter's 12th birthday.

By subtracting the number of postcards from Canada from the total collection, we find that there are 59 postcards from the United States.

The subject of this problem is subtraction in math. We know that Callie has 83 postcards in total, and 24 postcards are from Canada. The rest are from the United States. We can find out how many postcards are from the United States by subtracting the Canadian postcards from the total collection. So, 83 (total) - 24 (Canadian) = 59 postcards are from the United States.

90 is approximately 37.5 percent of 240.

To find the number that 90 is 37.5% of, we can set up the following proportion:

90 is to x as 37.5 is to 100

This can be expressed as:

90/x = 37.5/100

To solve for x, we can cross-multiply:

37.5 * x = 90 * 100

Now, divide both sides of the equation by 37.5 to isolate x:

x = (90 * 100) / 37.5

Simplifying the expression on the right side:

x = 9000 / 37.5

Dividing 9000 by 37.5:

x ≈ 240

37.5% of 240 is 90.

90 is 37.5% of 240.

Part = (Percentage / 100) * Whole

In this case, we are given the part (90) and the percentage (37.5%), and we need to find the whole.

Whole = Part / (Percentage / 100)

Substituting the given values:

Whole = 90 / (37.5 / 100)

Whole = 90 / 0.375

Whole = 240

So, 90 is 37.5% of 240.

A line parallel to this one would need to have the same slope. This line is in the slope/intercept form, and shows us that the slope of this line is 9. Therefore, any line with a slope of 9 would be parallel to y = 9x. For example, the lines y = 9x + 3 and y = 9x - 40 would be parallel to this one.

To find out how long it will take Jim to drive 760 miles at the same pace as before, we divide the total distance by his average speed.

To find out how long it will take Jim to drive 760 miles, we need to determine his average speed and use it to calculate the time. Since we know that he drove 152 miles in 4 hours, we can find his average speed by dividing the distance by the time: 152 miles / 4 hours = 38 miles per hour.

We can use this average speed to calculate the time it will take him to drive 760 miles: 760 miles / 38 miles per hour = 20 hours. Therefore, it will take Jim approximately 20 hours to drive 760 miles if he maintains the same pace.

To earn the total amount by selling 250 magazine subscriptions, we need to calculate the payment for each subscription and then sum them up using the arithmetic series formula. The total earnings will be $6,312.50.

To calculate how much you will earn by selling 250 magazine subscriptions, we need to determine the payments for each individual subscription and then add them up. Based on the given information, the first subscription pays $1.25, and for each additional subscription, the payment increases by 20 cents. We can use a formula to find the payment for each subscription:

Payment = $1.25 + ($0.20 x (n-1))

where n is the number of subscriptions sold. Now, let's calculate the payments for 250 subscriptions:

Now, we need to add up all the individual payments to find the total earnings:

Total earnings = Payment for the 1st subscription + Payment for the 2nd subscription + ... + Payment for the 250th subscription

Total earnings = $1.25 + $1.45 + $1.65 + ... + $49.25

To simplify the calculation, we can notice that the payments form an arithmetic sequence with a common difference of $0.20. We can use the arithmetic series formula to find the sum of the payments:

Total earnings = (n/2) x (first term + last term)

Plugging in the values, we get:

Total earnings = (250/2) x ($1.25 + $49.25) = 125 x $50.50 = $6,312.50

Therefore, you will earn $6,312.50 by selling 250 magazine subscriptions.

By selling 250 magazine subscriptions, you will earn $51.05.

To find out how much you will earn by selling 250 magazine subscriptions, we need to determine the amount you will earn for each subscription. Given that the company pays $1.25 for the first subscription and increases the payment by 20 cents for each additional one, we can set up an arithmetic sequence to calculate the total earnings.

The sequence starts with $1.25 and increases by 20 cents each time. The formula for the nth term of an arithmetic sequence is:

an = a1 + (n - 1)d

where an is the nth term, a1  is the first term, n is the number of terms, and d is the common difference. In this case, a1 = $1.25 , d = 0.20 , and n = 250.

By substituting these values into the formula, we can calculate the total earnings:

a250 = 1.25 + (250 - 1) * 0.20

a250 = 1.25 + 249 * 0.20

a250 = 1.25 + 49.80

a250 = 51.05

Therefore, you will earn $51.05 by selling 250 magazine subscriptions.

Hi!

[tex]13m=12-m[/tex]

[tex]13m+m=12-m+m[/tex]

[tex]14m=12[/tex]

[tex]\frac{14m}{14}=\frac{12}{14}[/tex]

[tex]m=\frac{6}{7}[/tex]

Explanation: First you had to do is add m to from both sides. It gave us 13m+m=12-m+m. Then you can simplify, it gave us 14m=12. You can also divide by 14 from both sides. It gave us 14m/14=12/14. And the answer is going to be m=6/7 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day! -Charlie

The value of m is 0.85

To solve for m in the equation [tex]\(13m = 12 - m\)[/tex], we need to isolate m on one side of the equation. Here's the step-by-step solution:

1. Start with the given equation:

[tex]\[ 13m = 12 - m \][/tex]

2. Add m to both sides of the equation to get all the m terms on one side:

[tex]\[ 13m + m = 12 \][/tex]

[tex]\[ 14m = 12 \][/tex]

3. Now, divide both sides of the equation by 14 to solve for m:

[tex]\[ \frac{14m}{14} = \frac{12}{14} \][/tex]

[tex]\[ m = \frac{12}{14} \][/tex]

The width of the rectangular garden will be 6 feet.

The rectangle is defined as a quadrilateral having four sides and the angle suspended by all the sides is equal to 360 degrees. The perimeter is the sum of all the sides of the rectangle.

Given that the perimeter of a garden is 42 feet. The length is 15 feet.
