For a circle with a radius = 4.3, find the following

Answer:

Each lap is 1.25 miles, so multiply the number of laps with 1.25 to get your answer.

Step-by-step explanation:

1 lap = 1.25 miles

2 laps = 2.5 miles

3 laps = 3.75 miles

4 laps = 5 miles

5 laps = 6.25 miles

6 laps = 7.5 miles

7 laps = 8.75 miles

8 laps = 10 miles

9 laps = 11.25 miles

10 laps = 12.5 miles

Answer: Making them into improper fractions will really help you with subtracting mixed fractions! For example 2[tex]\frac{1}{5} \\[/tex] - 1[tex]\frac{1}{4}[/tex].

Making them into improper fractions will turn the expression into [tex]\frac{11}{5}[/tex] - [tex]\frac{5}{4}[/tex].

Turn the denominators into the greatest common multiple, so the greatest common multiple of 5 and 4 is 20. Meaning you multiply  [tex]\frac{11}{5}[/tex] by 4 and [tex]\frac{5}{4}[/tex] by 5.

You now have [tex]\frac{44}{20} -\frac{25}{20}[/tex], which is much easier to work with. Simply subtract the numerators, and you should get [tex]\frac{19}{20}[/tex].

Minimum Unit Cost = $14,362

Step-by-step explanation:

The standard form of a quadratic is given by:

ax^2 + bx + c

So for our function, we can say,

a = 0.6

b = -108

c = 19,222

We can find the vertex (x-coordinate where minimum value occurs) by the formula -b/2a

So,

-(-108)/2(0.6) = 108/1.2 = 90

Plugging this value into original function would give us the minimum (unit cost):

Step-by-step explanation:

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

The perimeter of a rectangle.

= 2 ( length + width)

The number of 2(3/8) inches tickets to fit into the length of the wall is

154 tickets.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

The perimeter of a rectangle.

= 2 ( length + width)

The wall is rectangular and has a perimeter of 408 ⅜ inches.

This means,

408 (3/8) = 2 (length + width)

3267/8 = 2 (length + width) _____(1)

Now,

The total width of the wall.

= 2 width

Now,

Length of the square stickers = 2 (3/8) inches = 19/8 inches

The number of stickers needed to cover the width of the wall = 18

2 width = 18 x 19/8 inches.

2width = 18 x 19/8

width = 171/8 inches

Now,

From (1) we get,

3267/8 = 2 (length + width)

3267/8 = 2 (length + 171/8)

3267/8 - 342/8 = 2 length

2925/(8 x 2) = length

2length = 2925/(8 x 2)

2length = 2925/8

The number of stickers to cover the total length.

= 2925/8 ÷19/8

= (2925 x 8)/ (19 x 8)

= 154

Thus,

The number of 2(3/8) inches tickets to fit into the length of the wall is

154 tickets.

Step-by-step explanation:

The given equation is,

→ c(d) = 0.24d + 34

Now the required cost will be,

→ c(d) = 0.24d + 34

→ c(206) = 0.24(206) + 34

→ c(206) = 49.44 + 34

Present value of the quarterly payments of $1,635 at 4.2% compounded quarterly over a 3 year period is $18,344

percentage, a relative value indicating hundredth parts of any quantity.

The present value of the quarterly payments of $1,635 at 4.2% compounded quarterly over a 3 year period is calculated as follows:

Present Value = $1,635 × PVIFA ( 4.2%/4 ,3 Years)

Present Value = $1,635 × PVIFA (1.05% ,12)

= $1,635 × 11.21960

= $18,344

The present value of the quarterly payments of $1,635 at 4.2% compounded quarterly over a 3 year period is $18,344

In the velocity - time graph, the value of t is 180 seconds

Velocity-time graph is a plot between Velocity and Time. It shows the Motion of the object that moves in a Straight Line. Magnitude of Velocity at a given instant is equal to its Instantaneous Speed. It is drawn for 1-D motion only and can take both positive and negative values.

The formula of speed by using the distance and time represented as

speed = distance / time

In the velocity time graph, we have we walked back home at constant speed of 2m/s

This can be represented mathematically as

2 = 150 / t - 105

solve for t in the equation

150 = 2(t - 105)

150 = 2t - 210

2t = 150 + 210

What is an example of a unitary method?

A single or distinct unit is referred to by the word unitary. Therefore, the goal of this strategy is to establish values in reference to a single unit.

Obtaining more data, simplifying the model (choosing a simpler technique, reducing the amount of parameters or features utilized, or regularizing the model), or lowering the noise in the training data are all potential remedies for overfitting.

Step-by-step explanation:

The other midpoint is 3+9i in the given complex plane.

Given that,

We know that the middle point is: (-1+i)

And the end point  is: (-5-7i)

We know that the formula to find the middle point is:

(x1+ x2 /2, z1+z2/2)

We wish to find the point x1,z1

So we can write the following equation

x1 + (-5)/2 = -1  --------> 1

and

z1 + (-7i)/2 = i ----------->2

Now we clear x1 from equation (i) and clear z1 from equation (ii)

For equation (i) we have:

-2 = x1 -5

x1 =3

The time saved will be: x - m/k This is a simple exercise in manipulating symbols. Let's take a look at the problem and break it down. "Stanley drives m miles in x hours" This statement immediately gives us 2 variables; "m" to represent how many miles the trip is and "x" for the number of hours it took Stanley to drive that far. Now let's look at the next statement. "How many hours would he save if he drove the same distance at k miles per hour?" This statement gives us another variable "k" for a new speed and gives us the question to answer. How many hours would Stanley save if he made the trip at a different speed. Since we're interested in hours saved, we need 2 different time values. They are 1. How much time did Stanley originally take? 2. How much time will the new speed make Stanley take? Looking at m, x, and k. We can immediately see that x is the original time that Stanley took. So we have that value. But we don't have any value for how long will it take at a new speed. But can we calculate it? And the answer to that is YES. The time it will take is the distance divided by the new speed. And that would be m/k. And since we're looking for savings, we just need to subtract the two time values. So our equation becomes x - m/k where x = original time taken m = distance of trip k = new speed to drive at.
