Answer:
Apothem = 3.3 units
Step-by-step explanation:
A regular nonagon has an area of 102.4 and one side length measures 7 units long. Find the apothem. Round to the nearest tenth, if necessary.
The formula to find the area of a polygon when given Apothem and Side length =
A = 1/2 × a × p
Where p = no of sides of polygon × side length
In the above question,
We are given a polygon = nonagon = 9 sides
Side length = 7 units
p = 9 × 7 = 63 units
Area = 102.4 square units
Apothem = a = ?
We substitute into the formula
102.4 = 1/2 × a × 63
102.4 = 63a/2
Cross Multiply
102.4 × 2 = 63a
Divide both sides by 63
a = 102.4 × 2/63
a = 3.2507936508 units
Approximately to the nearest tenth = 3.3 units
Jasmine had $120,000 last year. This year she has $50,000
What is the percentage difference?
The percentage difference if Jasmine had $120,000 last year and this year she has $50,000 is 41.6%.
What is percentage?As it is clear from the term per cent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.
Given:
The last year value = $120000,
The new value of this year = $50000,
Calculate the percentage by the following formula,
Percentage difference = The new value of this year / The last year's value ×100
Substitute value
Percentage difference = 50000 / 120000 × 100
Percentage difference = 41.6%
Therefore, the percentage difference if Jasmine had $120,000 last year and this year she has $50,000 is 41.6%.

You and a friend are racing each other to swim 500 meters. You complete 50 meters in 45 seconds. Your friend completes 150 meters in 2 minutes. Who won the race and by how much?? no links
Answer:
your friend by 50 seconds
Step-by-step explanation:
150 divided by 3 equals to 50 so you would also divide 120 minutes by 3 to get 40
You: 50 meters per 45 seconds
Friend: 50 meters in 40 seconds
50 times 10 equals 500 meters so we will multiply both number of seconds by 10
You:45*10=450
Friend: 40*10=400
450>400 so the friend swims the fastest
450-400= is 50 seconds
So the friend swims the fastest by 50 seconds

Suppose you are asked to find the missing vertex of a rectangle in a coordinate plane. What information will help you determine the missing coordinate?
The information to determine the missing coordinates is given below.
What are coordinates?Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.
Given;
A rectangle is drawn in the coordinate plane.
That means, each vertex has coordinates.
To find the missing vertex of a rectangle in a coordinate plane:
We should have the three known vertices.
Then use the formula,
w = t + v - u for each of the coordinates.
Therefore, the information to determine the missing coordinates is given above.

Which graph best represents the equation y = -2x + 5?
Answer:
B) The top right choice.
Step-by-step explanation:
The graph of the equation y = - 2x + 5 is shown in figure.
Option 2 is true.
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation is,
⇒ y = - 2x + 5
Now,
Since, The equation is,
⇒ y = - 2x + 5
By comparing of the slope - intercept form of the equation of line,
y = mx + b we get;
⇒ Slope = - 2
And, The y - intercept = 5
So, The graph of the equation is passes through the point (0, 5) with slope - 2.

How long she waits in Wellington
From the question:
She takes the 10 30 from Christchurch
So:
[tex]Christchurch\ Depart = 10\ 30[/tex]
This implies that:
She has to wait until Wellington arrives at 11 15
So:
[tex]Wellington\ Arrives= 11\ 15[/tex]
So, the wait time is:
[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]
