A buisness in the florida keys offers key west jet ski tours for the following rates:Time (in hours) Price (in dollars)3/4 hour $90.001 1/2 hours $130.002 hours $180.00Are the two quantities, time and price, proportionally related? Explain.
Answers
Two quantities are proportionally related if the ratio between them is constant
\(\begin{gathered} \frac{price}{time}=\frac{90}{\frac{3}{4}}=90\cdot\frac{4}{3}=120 \\ \frac{price}{time}=\frac{130}{\frac{3}{2}}=130\cdot\frac{2}{3}=\frac{260}{3}=86\frac{2}{3} \\ \frac{price}{time}=\frac{180}{2}=90 \end{gathered}\)Given that the results are different between them, then the two quantities are not proportionally related

Step-by-step explanation:
To round 6.752 to the nearest tenth consider the hundredths’ value of 6.752, which is 5 and equal or more than 5. Therefore, the tenths value of 6.752 increases by 1 to 8.
For f(x) = √(x+4) , what is the value of the function when x = 8 ? Round to the nearest hundredth.
NEED ANSWER ASAP!!
Answers
Answer:
exact form : 2√3
decimal form : 3.46410161… or 3.46
hope this helps you!
Answer:
The value of the function is \(\sqrt{12}\). Rounded to the nearest hundredth, the answer is 3.46
Step-by-step explanation:
We are given the value of x, so we simply have to evaluate the function:
\(f(x)=\sqrt{x+4}\)
Substitute 8
\(f(8)=\sqrt{8+4}\)
Add in the radical
\(\sqrt{12}\)
The value of the function is sqrt(12).

how do u find weather the system has one solution,no solutiin,solution,infinitely many solutions
Answers
1st case: the system has one solution
For example:
Given this system:
\(\begin{gathered} x+y=5 \\ 2x-y=4 \\ \text{Let:} \\ x+y=5\text{ (1)} \\ 2x-y=4\text{ (2)} \\ \text{ Using elimination method:} \\ (1)+(2)\colon \\ x+2x+y-y=9 \\ 3x=9 \\ x=\frac{9}{3} \\ x=3 \\ y=5-x \\ y=5-3 \\ y=2 \end{gathered}\)graphically, a system has a solution if the two lines intersect, the point of intersection is the solution.
--------------------------------------------
2nd case: the system has no solution
A system has no solution, when the lines are parallel and have different intercepts, for example:
\(\begin{gathered} y=2x+1 \\ y=2x-3 \end{gathered}\)as you can see the lines never cross each other.
3rd case: the system has infinitely many solutions
occurs when one line is a scalar multiple of the other, in other words it is the same line. for example:
\(\begin{gathered} x+y=5 \\ 2x+2y=10 \end{gathered}\)

Observe that

\(\implies (2 + 1) (2^2 + 1) = (2^2 - 1) (2^2 + 1) = 2^4 - 1\)
\(\implies (2 + 1) (2^2 + 1) (2^4 + 1) = (2^4 - 1) (2^4 + 1) = 2^8 - 1\)
\(\implies (2 + 1) (2^2 + 1) (2^4 + 1) (2^8 + 1) = (2^8 - 1) (2^8 + 1) = 2^{16} - 1\)
and so on. More generally, for \(n\in\Bbb N\),
\((2 + 1) (2^2 + 1) (2^4 + 1) \cdots \left(2^{2^n} + 1\right) = 2^{2^{n+1}} - 1\)

#2 Jamal is an apprentice on a boat on Long Island Sound. He is helping the captain collect samples of
marine life for an environmental study, and the captain is teaching him about nautical navigation.
When the boat leaves the environmental station, it will return to its home port 9 nautical miles away.
If
the boat maintains a constant speed of 15 knots (nautical miles per hour), how many minutes will the
trip take?
Answers
Answer:
The trip will take 36 minutes.
Step-by-step explanation:
This question can be solved using a rule of three.
The boat maintains a constant speed of 15 knots (nautical miles per hour). How many minutes it will take to return to its home port 9 nautical miles away?
So in 60 minutes, 15 nautical miles. How many minutes for 9 nautical miles?
60 minutes - 15 nautical miles
x minutes - 9 nautical miles
\(15x = 60*9\)
\(x = \frac{60*9}{15}\)
\(x = 36\)
The trip will take 36 minutes.
Angus earns $8.80 an hour at his Saturday job and $7.50 per hour at his after school job. Last week he earned a total of $127.80. The hours he worked after school were four hours more than he worked on Saturday. How many hours did he work on Saturday?
Answers
Based on equations, Angus worked 6 hours on Saturday and 10 hours at his after-school job last week earning a total of $127.80.
How the hours are determined:The hourly rate at Angus' Saturday job = $8.80
The hourly rate at Angus' after-school job = $7.50
The total earnings last week = $127.80
Let the hours Angus worked at Saturday job = x
Let the hours Angus worked after-school = 4 + x
The total hours worked = x + x + 4
2x + 4
Equations:The total earnings last week 127.80 = 8.8x + 7.5x + 4 (7.5)
127.80 = 8.8x + 7.5x + 30
127.8 - 30 = 16.3x
Hours worked at Saturday Job:x = 6 hours
Hours worked at After-School Job:x + 4 = 10 hours
2x + 4 = 16 (12 + 4)
Check:
Earnings at Saturday job = $52.80 ($8.80 x 6)
Earnings at after-school job = $75.00 ($7.50 x 10)
Total earnings = $127.80

Find an equation for the line below.
Answers
Answer:
y = \(\frac{4}{5}\) x + \(\frac{6}{5}\)
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 4, - 2) and (x₂, y₂ ) = (6, 6) ← 2 points on the line
m = \(\frac{6-(-2)}{6-(-4)}\) = \(\frac{6+2}{6+4}\) = \(\frac{8}{10}\) = \(\frac{4}{5}\) , then
y = \(\frac{4}{5}\) x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (6, 6 ) , then
6 = \(\frac{24}{5}\) + c ⇒ c = \(\frac{30}{5}\) - \(\frac{24}{5}\) = \(\frac{6}{5}\)
y = \(\frac{4}{5}\) x + \(\frac{6}{5}\) ← equation of line
Which of the following is a solution to the inequality below? 10 ≤ h
Answers
Any Value of h that is equal to or greater than 10, including 10 itself, is a solution to the inequality 10 ≤ h.
The inequality given is 10 ≤ h. To find the solution(s), we need to determine which values of h satisfy this inequality.
Let's analyze the inequality:
10 ≤ h
This inequality states that h is greater than or equal to 10. In other words, any value of h that is greater than or equal to 10 will satisfy this inequality.
So, the solution to the inequality is any value of h that is greater than or equal to 10.
To express this in set notation, we can write:
Solution: {h | h ≥ 10}
In interval notation, we can represent the solution as:
Solution: [10, ∞)
This means that the solution to the inequality is the interval starting from 10 and going to positive infinity.
Therefore, any value of h that is equal to or greater than 10, including 10 itself, is a solution to the inequality 10 ≤ h.

Answers
Based on their given probabilities, e would expect the color blue or green to be spun approximately 75 times in this experiment.
How many times can the blue or green color be obtained?To find the expected number of times the color blue or green will be spun, we first need to add their probabilities:
0.25 + 0.125 = 0.375
This means that, on average, we would expect to see blue or green spun 0.375 times for every spin. To find the expected number of times this will happen over 200 spins, we can multiply the probability by the number of spins:

What is the volume of the composite figure? ASAP PLEASE!!!!
Answers
Answer:
74ft³
Step-by-step explanation:
Okay, so it's basically 3 rectangular figures smashed together so:
We'll do the 2 biggest one's first:
the formula for the volume of a rectangular figure is base x height so we first have to find the base:
4 x 3 = 12
So then we just plug our stuff in here:
12 x 3 = 36
Now there's 2 of these rectangles though so:
36 x 2 = 72
Now we're going to do the one in the middle:
1 x 2 = 2
2 x 1 = 2
Now we add that all together:
72 + 2 = 74
So, the volume of the composite figure is 74ft³
