Hope has 6 nickels (x) and 10 quarters (x + 4).

How many of each coin Hope has if she has 4 more quarters than nickels and they have a combined value of 280 cents. To solve this problem, we can use algebraic equations.

Let's assume the number of nickels Hope has is x. Then, the number of quarters she has would be x + 4.

Now, we need to find the total value of the coins. Each nickel is worth 5 cents, so the total value of nickels is 5x cents. Similarly, each quarter is worth 25 cents, so the total value of quarters is 25(x + 4) cents. The combined value of the coins is 280 cents, so we can set up an equation:

5x + 25(x + 4) = 280

Simplify and solve for x:

5x + 25x + 100 = 280
30x = 180
x = 6

Therefore, Hope has 6 nickels (x) and 10 quarters (x + 4).

The height of the cone is 13.38 units

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the centre of base) called the apex or vertex.

The volume of a cone = 1/3 πr²h

volume = 2016 units³

r = d/2 = 24/2 = 12 units

2016 = 1/3 × 3.14 × 12² h

6048 = 452.16h

h = 6048/452.16

h = 13.38units

The median of 49 is the most accurate to use, since the data is skewed.

Distribution refers to the pattern of variation in a dataset. Specifically, it refers to how the values in the dataset are spread out or clustered together.

The most appropriate measure of center to represent the data depends on the shape of the distribution. In this case, we can see from the histogram that the data is skewed to the right, with a longer tail of higher values.

Therefore, the correct answer is: the median of 49 is the most accurate to use, since the data is skewed. This represents the middle value of the data when it is arranged in order, and is less sensitive to the outliers at the high end of the distribution. Using the median can give a more accurate representation of the typical donations received by the charity.

In order to have a potential value of $12,000 at a simple rate of interest of 8.0% after 6 years, the current value you must invest is therefore approximately $8,108.11.

A formula called Simple Interest (S.I.) is used to determine how much interest will be charged on a certain principal sum of money at a specific interest rate. For instance, if a person borrows Rs. 5000 for two years at a rate of 10 p.a., they will be compelled to pay S.I. on the whole amount borrowed during those two years.

For simple interest, use the formula:

A = P(1 + rt)

where r is the interest rate, t is the amount of time in years, A represents the future value, P is indeed the present value, and so on.

This formula can be changed to account for P:

P = A / (1 + rt)

By entering the specified values, we obtain:

P = 12,000 / (1 + 0.08 x 6)

P = 12,000 / 1.48

P = $8,108.11

Anderson traveled 15 mph to go to the restaurant and 12 mph to get home. Anderson went at 15 mph for 3 hours and at 12 mph for 6 hours. if the entire trip took 9 hours.

    The given speed Anderson, the total time taken, and asked to find the time traveled at each speed:

         Speed, [tex]S_1[/tex] = 15 mph

         Speed, [tex]S_2[/tex] = 12 mph

         Total time, [tex]t[/tex] = 9 hours

         Time traveled with speed 1,

         [tex]t_1[/tex] Time traveled with speed 2, [tex]t_2[/tex]

To solve the given problem, let's use the following formula:

         Total   [tex]t[/tex] (time) = [tex]t_1[/tex] ( time 1) + [tex]t_2[/tex] (time 2)

   Now, time 1 can be represented as

          [tex]t_1[/tex] (time 1) = [tex]d[/tex] (distance) /  [tex]S_1[/tex] (speed 1)

Similarly, time 2 can be represented as:

           [tex]t_2[/tex] (time 2) = [tex]d[/tex] (distance) /  [tex]S_2[/tex] (speed 2)

 Here, we need to find the time traveled at each speed. Let's use these equations to solve the given problem.

      Time traveled with speed 1, [tex]t_1[/tex]  = [tex]d[/tex] /  [tex]S_1[/tex]

      Time traveled with speed 2,  [tex]t_2[/tex] = [tex]d[/tex] /  [tex]S_2[/tex]

As we know the total time, we can find the value of d in terms of [tex]t[/tex].

        So, [tex]d[/tex] =  [tex]S_1[/tex] * [tex]t_1[/tex]  =  [tex]S_2[/tex]  *  [tex]t_2[/tex]

     From the above equation, we can write: [tex]t_1[/tex]  /  [tex]t_2[/tex] =  [tex]S_2[/tex]  /  [tex]S_1[/tex] [tex]t_2[/tex]

                                                                                    =  [tex]t[/tex]  - [tex]t_1[/tex]

     Substitute the value of  [tex]t_2[/tex]  in equation(1):

           [tex]t_1[/tex]  / ([tex]t[/tex] - [tex]t_1[/tex] ) =  [tex]S_2[/tex]  / [tex]S_1[/tex][tex]t_1[/tex]  [tex]S_1[/tex]

                            = ([tex]t[/tex] - [tex]t_1[/tex] ) [tex]S_2[/tex] .[tex]t_1[/tex] . [tex]S_1[/tex] + [tex]t_1[/tex]  [tex]S_2[/tex]

                            = [tex]tS_1[/tex][tex]t_1[/tex]  

                            = [tex]tS_1[/tex] / ( [tex]S_1[/tex] +  [tex]S_2[/tex] ) [tex]t_2[/tex]  

                            =  [tex]t[/tex]  - [tex]t_1[/tex]  

                            = [tex]tS_2[/tex] / ( [tex]S_1[/tex] +  [tex]S_2[/tex] )

To find the equation of a line parallel to y = (1/3)x + 4 and pass through the point (-6, 1), we can use the fact that parallel lines have the same slope. The slope of the given line is 1/3, so the slope of the parallel line must also be 1/3.

Now we have the slope (m = 1/3) and a point on the line (-6, 1), so we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Plugging in the values, we get:
