The concepts of percentage, rate, and base can be defined as follows:

In our daily lives, we utilize these three concepts in many different ways, some examples of which are outlined below:

When we go shopping, we frequently come across discounts or sale prices offered as percentages off the original price. For example, if an item was initially $40 but is now available at a discount of 20%, it will be priced at $32.

Rates enable us to measure speed when we are driving or running with unit-based measurements. In addition, rates allow us to compare prices during grocery shopping, where we might need to know the cost per pound of apples and/or calculate interests on investments or loans.

Bases have utility while dealing with ratios or proportions. For instance, if we wish to prepare food for eight people instead of four, one can take the existing recipe as a base and adjust ingredient quantities proportionally.

The formulas P = B × R, B = P / R, and R = P / B are basic calculations that correspond to different values based on the given percentage, rate, or base. For instance, P = B × R allows us to obtain the value of P given the input of B and R.

Meanwhile, B = P / R enables us to get the value of B by punching in P and R much like calculating interest paid out each month in compound-interest cases.

Finally, R = P / B yields the value of R using inputs for P and B. These formulas find rampant use in fields like finance, economics, and mathematics.

According to the information, the distance from your starting point to the library is 4 miles.

To calculate how far do you live from the library we have to assume that the distance from the starting point to the library is "x" miles.

According to the problem, when you are 75% of the way there, you realize you forgot a book. It means you have traveled 75% of the distance, which is 0.75x miles.

Now, you turn around and bike back. When you are 1/3 of the way back, you realize you don't need the book, so you turn around again and bike 3.2 miles to the library.

From the starting point, you have traveled 0.75x miles to the point where you forgot the book, and then you traveled back 1/3 of 0.75x miles, which is (1/3)*0.75x = 0.25x miles.

Now you turn around again and bike 3.2 miles to the library. It means that the distance between the point where you realized you don't need the book and the library is 3.2 miles.

The circles are similar because you can translate Circle 1 using the transformation rule (0, -7) and then dilate it using a scale factor of 3/5.

Translation involves moving an object in a straight line without changing its size or shape. In this case, we can translate Circle 1 7 units down to match the y-coordinate of Circle 2. The transformation rule for this translation is (0, -7), since we are not changing the x-coordinate.

Dilation involves uniformly scaling an object, either making it larger or smaller. We can dilate Circle 1 by a scale factor of 3/5 to make it have the same radius as Circle 2. The scale factor is determined by taking the ratio of the radii:

scale factor = radius of Circle 2 / radius of Circle 1

scale factor = 9 / 15

scale factor = 3/5

The center of dilation is the center of Circle 1, since we want to preserve its position.

Therefore, we can transform Circle 1 into Circle 2 by translating it 7 units down and dilating it by a scale factor of 3/5. The transformation rule is:

The width of the brochure is 3/2 inches and the height is 10 inches.

Let's assume that the width of the brochure is x and the height is y.

The area of the brochure is given as 30 square inches:

xy = 30

The perimeter of the brochure is given as 23 inches:

2x + 2y = 23

We can use the second equation to solve for one variable in terms of the other.

2x + 2y = 23

2x = 23 - 2y

x = (23 - 2y)/2

Now we can substitute this expression for x into the equation for the area:

xy = 30

[(23 - 2y)/2]y = 30

23y/2 - y^2 = 60/2

y^2 - 23y/2 + 30 = 0

We can solve for y using the quadratic formula:

y = [23/2 ± sqrt((23/2)^2 - 4(1)(30))]/(2)

y = [23/2 ± sqrt(529/4 - 120)]/2

y = [23/2 ± sqrt(289/4)]/2

y = [23/2 ± 17/2]/2

y = 10 or y = 3/2

Since the height must be greater than the width, we can eliminate y = 3/2 as a solution.

So, y = 10 and

x = (23 - 2y)/2 = (23 - 20)/2 = 3/2

Therefore, the width of the brochure is 3/2 inches and the height is 10 inches.

Answer:

The silver will cost $1908.5125 to make one solid sphere

Step-by-step explanation:

The formula for the volume of a sphere is:

V = (4/3)πr^3

where r is the radius of the sphere.

Substituting the given value for the radius:

V = (4/3)π(4.5 cm)^3

= (4/3)(3.14)(91.125 cm^3)

= 381.7025 cm^3

The cost of the silver can be calculated by multiplying the volume by the cost per cm^3:

Cost = 381.7025 cm^3 × $5.00/cm^3

= $1908.5125

3. 504,875 shares

4. $10,829,568.75

5. $30,383,377.5

Step-by-step explanation:

1. For the first one, you just need to find 70% of 721,250, which we can do several ways:

If Allen owns 70% of Bull Corp, he owns 0.7 x 721,250 = 504,875 shares.

Therefore, Allen owns 504,875 shares of Bull Corp.

you can use cross-multiplication to solve this problem as well. Here's how:

Let X be the number of shares that Allen owns.

According to the problem, Allen owns 70% of the total number of shares, which is 721,250.
So we can write:

X/721,250 = 70/100

To solve for X, we can cross-multiply:

100X = 70 * 721,250

Simplifying the right-hand side:

100X = 50,487,500

Dividing both sides by 100:

X = 504,875

Therefore, Allen owns 504,875 shares of Bull Corp, which is the same answer we got earlier.

I added a picture below.

2. If Allen paid $21.45 PER share we just multiply that by he amount of shares, which is 504,875:

If Allen owns 504,875 shares of Bull Corp, and he paid $21.45 per share, his initial total investment would be:

Total investment = Number of shares * Price per share

Total investment = 504,875 * $21.45

Total investment = $10,829,568.75

Therefore, Allen's initial total investment was $10,830,093.75.
i added a picture for this too.

3. Just replace the 21.45 with 60.18:

If the shares are now worth $60.18, the total value of Allen's shares would be:

Total value = Number of shares * Current price per share

Total value = 504,875 * $60.18

Total value = $30,383,377.5

Therefore, the total value of Allen's shares now is $30,382,078.50.
