is the answer yess girl

we are given

[tex]\frac{17}{40}[/tex]

we can use long division method

Firstly, we will try to make denominator either 10 , 100 , 1000 , 10000 form

and then we can put decimal accordingly

Here , we are given 40 in the denominator

[tex]40 \times 25=1000[/tex]

so, we will multiply both top and bottom by 25

[tex]\frac{17}{40}=\frac{25\times 17}{25\times 40}[/tex]

[tex]\frac{17}{40}=\frac{425}{1000}[/tex]

now, we can put decimal to three places because we have 1000 in bottom

so, we get

[tex]\frac{17}{40}=0.425[/tex]...............Answer

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.

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 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.

For this case, the generic equation of a vertex shaped parabola is given by:

[tex]y = a (x-h) ^ 2 + k\\[/tex]

Where the vertex coordinates are (h, k)

Comparing with the given equation:

 [tex]f (x) = (x + 1) ^ 2 - 3\\[/tex]

It is observed that h = -1 and k = -3 to obtain the form of the generic equation.

To find the axis of symmetry we derive the given function:

[tex]f '(x) = 2 (x + 1)\\[/tex]

We equate this derivative to zero and clear the value of x

[tex]2 (x + 1) = 0\\[/tex]

[tex]x = -1\\[/tex]

Therefore the vertice of the parabola is:

[tex](h, k) = (-1, -3)\\[/tex]

And the axis of symmetry is:

[tex]x = -1\\[/tex]

Answer:

Graphic 3

The graph third represents the vertex and axis of symmetry of the function f(x) = (x + 1)² - 3 option third is correct.

Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

We have a function:

f(x) = (x + 1)² - 3

The above function is a quadratic function or parabolic function.

The vertex form of the function:

f(x) = (x - h)² + k

On comparing:

h = -1, k =  -3

(h, k) = (-1, -3) is the vertex of the function.

Axis of symmetery:

x + 1 = 0

x = -1

Thus, the graph third represents the vertex and axis of symmetry of the function f(x) = (x + 1)² - 3 option third is correct.

The original number is 3.

I actually began with the guess-and-check method, but seeing as that won't always work, let's go over the formal way. To get the original number, you first need to determine how many times the number was squared.

To make it simple, let's use x to focus on the exponents. The number was squared 3 times, so x^2, x^2, x^2. Basically, you need to multiply. 2 * 2 * 2 = 8. So, now find the 8th root of 6561 (depending on the calculator, you can just input it). You should come up with 3. Let me know if this part confuses you.

To find the next 2 numbers, you just need to continue the pattern.

6561^2 = 43,046,721

43,046,721^2 = 1,853,020,188,851,841

To my knowledge, which means this could be wrong, they're both perfect squares. Since the number to get them both were whole numbers, they should both have a square root that equals a whole number.

Original number (3): Not a perfect square (3 is not the square of any integer). First intermediate number (9): A perfect square (9 is the square of 3). Final number (6561): A perfect square (6561 is the square of 81). So, the only perfect square in the sequence is the first intermediate number, 9.

Here's why:

Original number: Starting with an unknown number, let's call it x. Squaring it gives us x^2.

First intermediate number: Squaring x^2 again, we get (x^2)^2 = x^4.

Final number: Finally, squaring x^4 one last time, we reach the given number, 6561: (x^4)^2 = x^8 = 6561.

Now, let's backtrack to find the original number x:

Since 6561 is the square of 81, and 81 is the square of 9, we can conclude that the original number x must be the square root of 9, which is 3.

Therefore, the sequence of numbers you provided is indeed correct:

Original number: 3 (squared to get 9)

First intermediate number: 9 (squared to get 81)

Final number: 81 (squared to get 6561)

2 ≤  2w +4 ≤ 12

Subtract 4 from all 3 terms:

-2 ≤ 2w ≤ 8

Divide all 3 terms by 2:

-1 ≤ w ≤4

Answer: The answer could be 34.

Step-by-step explanation: Since he used an average of 15 gallons per race we can divide 51 by 3 which gives us 17 and since it's average it doesn't have to be exact. Then we multiply by 17*2 which give us 34 and that's our answer. Im sorry if I'm incorrect I tried my best! Hope this helps!

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.

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.
