Answer:
The population around the tower is 111,862 people.
Step-by-step explanation:
In order to solve this problem we first need to calculate the area surrounded by the tower, since it's a circle we can apply the following formula:
tower area = pi*r²
tower area = pi*(4.9)² = 75.4296 miles²
For every mile² there are 1483 people, therefore:
population = area*density
population = 75.4296*1483 = 111,862
The population around the tower is 111,862 people.

Identify the function represented by the graph?
Answer:b
Step-by-step explanation: just common sense
To identify the function represented by a graph, one must analyze the slope, intercepts, and shape of the graph. The graph of a constant function is a horizontal line, while the predator-prey cycle would show an oscillating pattern. The potential energy graph in physics can display a double well pattern, while signal transduction might show a cascade over time, and motion graphs represent various types of movement.
Explanation:Identifying the function represented by a graph involves analyzing various elements such as the shape of the graph, its slope, and intercepts, as well as any restrictions on the domain. For instance, when you come across a graph of a function that appears as a straight line, it's crucial to look at the slope and y-intercept to determine the equation of the line. If the graph is a horizontal line, then the function represents a constant value indicating that no matter the change in the independent variable x, the dependent variable y remains the same.
For analyzing a predator-prey cycle, we need to recognize the typical oscillating pattern that represents populations of predators and preys over time. When interpreting graphs showing potential energy in physics, we are often looking at a function that might show the energy levels as a function of position, with critical points determined by solving relevant equations and considering derivatives to find minima and maxima.
In the context of a biological process such as signal transduction, creating a graph would involve plotting the stages of the signaling pathway over time, which would likely result in a plot showing the cascade of events leading from the signal to the final response. When considering the graphs of the position of a moving object over time, we might see different types of curves representing different types of motion, such as uniform motion depicted by a straight line or accelerated motion depicted by a parabolic curve.

only line t and line v
only line u and line v
only lines t, u, and v
By using the congruent angle relationships formed by transversal cutting parallel lines, we can infer that only lines t and v are parallel to line s, as they form corresponding angles of 89 degrees with transversal r, unlike line u, which forms a 91-degree angle.
The information given in the question indicates that a transversal r cuts four lines s, t, u, and v. By the information given for the angles formed by this transversal with each line, we can determine which lines are parallel to line s using the concept of alternate interior angles and corresponding angles, which are congruent if the lines are parallel Since the angle formed by the transversal and line s is 89 degrees and a corresponding angle formed by the transversal and line t is also 89 degrees, we can say that line s is parallel to line t.
Similarly, since another angle formed by transversal and line v is also 89 degrees, it implies that line s is also parallel to line v. However, line u has an angle of 91 degrees formed by the transversal, which does not match the 89-degree angle formed by the transversal with line s, indicating that line u is not parallel to line s. Given this information, the lines parallel to line s are only line t and line v.

Joe wants to buy a skateboard but he doesn't know if he has enough money. The price of the skateboard is $85 and the sales tax is 6%. What will be the total cost of the skateboard?
Answer:
$90.10
Step-by-step explanation:
price of the skateboard = $85
sales tax = 6%
Dollar value of sales tax = 6% of price of the skateboard
= 6% of $85 = (6/100) * $85 = ( 6* 85)/100 = $ 5.10
Total cost of the skateboard = price of the skateboard + sales tax value
substituting the value of price of the skateboard and sales tax value, calculated above, we have
Total cost of the skateboard = $85 + $ 5.10 = $90.10

Six words have 2 vowels and 2 consonants .How many letters are there in 6 words?How many vowels consonants
Answer:
24, 12, 12
Step-by-step explanation:
I do not understand the question, but I believe you gave us how many vowels and consonants are in a word. Then you asked us for how many of them were in 6 words, which is simple math of 4 times 6. I don't get the last part, but I think you asked how many consonants in 6 words, and how many vowels in six words, another simple math question, 2 times 6.
In the English language, 5 letters are typically considered vowels: a, e, i, o, and u, with 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word. To find out how many vowels and consonants there are in six words, we need more information about the specific six words.
Explanation:In the English language, 5 letters are typically considered vowels: a, e, i, o, and u. However, there are 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word.
To find out how many vowels and consonants there are in six words, we need more information about the specific six words. If each of the six words has 2 vowels and 2 consonants, then the total number of letters in the six words would be 6 x (2 + 2) = 24.
We are planning a reception for our daughter. The hall that we are renting charges a $50 cleanup fee. In addition to the cleanup fee, they charge $33 per guest for food and drinks.
If we have $3,300.00 available, what is the maximum number of guest we can invite without going over our budget?
Answer:
98 guests
Step-by-step explanation:
First, you would take the amount of money available, $3,300.00, and subtract the cleanup fee ($50) from that.
You would get $3,250
Next, you divide $3,250 by the amount of money per guest ($33).
Your total is 98.48 repeated
That rounds to 98 people, since you can't go over.

Below is the graph of equation y= |x+2|-1. Use this graph to find all values of x such that...
y<0
To find the values of x such that y is less than 0 in the equation y = |x + 2| - 1, we set y less than 0 and solve for x. The values of x that satisfy y < 0 are x < -1.
Explanation:To find the values of x such that y is less than 0, we need to determine the portion of the graph below the x-axis, since y is negative in that region. Given the equation y = |x + 2| - 1, we can set y less than 0 and solve for x.
Setting y = 0, we have 0 = |x + 2| - 1. Adding 1 to both sides, we get 1 = |x + 2|. When the expression inside the absolute value is positive, the absolute value will be the same. Therefore, we can write x + 2 = 1. Solving for x, we get x = -1.
So, the values of x such that y is less than 0 are x < -1.

You switch the positions of two items on your menu. Chicken tenders sales drop from $800 to $600. Food cost for chicken tenders is 25%. Cheeseburger sales rise from $500 to $700. Food cost for cheeseburgers is 20%. Was this a good move?
a) Yes, gross margin increased
b) No, gross margin decreased
c) Didn't change gross margin
Answer:
yes gross margin increased
Step-by-step explanation:
Final answer:
a) Yes, gross margin increased
Switching the menu items resulted in an overall increase in gross margin by $10, as the $60 increase in gross margin from cheeseburger sales exceeded the $50 decrease in gross margin from chicken tenders. Therefore, this was a good move.
Explanation:
To determine whether switching the positions of two menu items was a good move, we should calculate the change in gross margin for both items. Gross margin is calculated as sales minus the cost of goods sold (COGS) and reflects the profitability prior to accounting for operating expenses.
For chicken tenders, the drop in sales from $800 to $600 represents a $200 decrease. With a food cost of 25%, the COGS for chicken tenders would be 25% of sales. Before the switch, the COGS was $200 (25% of $800), and after the switch, it became $150 (25% of $600). This means that the gross margin for chicken tenders decreased by $50 (from $600 to $550).
For cheeseburgers, the increase in sales from $500 to $700 is a $200 increase. The food cost being 20%, we had an initial COGS of $100 (20% of $500) and a new COGS of $140 (20% of $700). Consequently, the gross margin for cheeseburgers increased by $60 (from $400 to $460).
Comparing the two changes in gross margin, the increase for cheeseburgers exceeds the decrease for chicken tenders by $10 ($60 increase for cheeseburgers minus $50 decrease for chicken tenders). Therefore, the overall gross margin increased as a result of the switch.
The answer to the question is: a) Yes, gross margin increased.
