Answer: 36.2
Step-by-step explanation:

Malcolm trains on his kayak every weekend. He paddles upstream (against current) for 3 ½ hours and then returns downstream (with current) in 2hrs 6 minutes. If the river flows at 3km/ h, find:
* The paddling speed in still water
* The distance he paddles upstream.
If Malcolm trains on his kayak every weekend. The speed is 12km/h and the distance is 31.5km.
How to find the speed and distance?Let's call Malcolm's paddling speed in still water "v".
When paddling upstream, Malcolm is fighting the current, so his effective speed is v - 3 km/h. And when paddling downstream, his effective speed is v + 3 km/h.
The time it takes for him to paddle upstream= 3.5 hours
Distance he covers in this time = (v - 3) * 3.5.
The time it takes for him to paddle downstream = 2.1 hours
Distance he covers in this time = (v + 3) * 2.1.
Let set the sum of these two distances equal to each other and solve for v:
(v - 3) * 3.5 = (v + 3) * 2.1
Expanding both sides:
3.5v - 10.5 = 2.1v + 6.3
Subtracting 2.1v from both sides:
1.4v - 10.5 = 6.3
Adding 10.5 to both sides:
1.4v = 16.8
Dividing both sides by 1.4:
v = 12 km/h
So Malcolm's paddling speed in still water is 12 km/h. To find the distance he paddles upstream, we can use the formula (v - 3) * 3.5, which gives us:
(12 - 3) * 3.5 = 9 * 3.5 = 31.5 km
Therefore the distance Malcolm paddles upstream is 31.5 km.

The Perimeter of the pentagon ABCDE is 17 units.
What is Distance Formula?If two points in coordinates plane P(a, b) and Q(c, d) then the distance between these points are
PQ = √(c-a)² + (d-b)²
Given:
The coordinates of Pentagon are A (4, 3), B (7, 3), C (8, 0), and D (2, -3) and E(0, 1).
Using Distance formula
AB = √(7-4)² + (3-3)²
AB = √9
AB = 3
BC = √(8-7)² + (0-3)²
BC = √1 + 9
BC = √10
CD = √(2-8)² + (-3-0)²
CD = √36 + 9
CD = √45
CD = 3√5
DE = √(0-2)² + (-3-1)²
DE = √4 + 16
DE = √20
DE = 2√5

2. 36 inches
Step-by-step explanation: Solve for side b using the Pythagorean therom since this is a right triangle.
[tex]a^2+b^2=c^2[/tex] - Where c is the largest side aka hypotenuse(if you are unsure, look at the side opposite to the right angle)
Substitute the given values to solve for the unknown side

Subtract 81 from both sides
[tex]b^2=144[/tex]
Which means
[tex]b=+-12[/tex]
but since its a triangle in the first quadrant and can only contain positive values, we disregard the negative solution. So b=12.
Lastly, for perimeter, just add all the side lengths together.

A hot-air balloon has a 14
-foot diameter that is being deflated at a rate of 0.25
feet per minute.
How many minutes, x
, will it take before the balloon has shrunk to a diameter of 8
feet?
Answer:
Step-by-step explanation:
The rate of deflation of the hot-air balloon is 0.25 feet per minute. Let's represent the diameter of the balloon at any time t in minutes as D(t).
We know that D(0) = 14 feet (initial diameter) and we want to find x when D(x) = 8 feet.
Using the fact that the rate of change of D with respect to time is -0.25 (negative because the diameter is decreasing), we can set up a differential equation:
dD/dt = -0.25
Separating variables and integrating, we get:
∫(1/D) dD = ∫(-0.25) dt
ln|D| = -0.25t + C
where C is the constant of integration.
Using the initial condition D(0) = 14, we get:
ln|14| = C
C = ln(14)
Substituting this value of C into the equation, we get:
ln|D| = -0.25t + ln(14)
Taking the exponential of both sides, we get:
|D| = e^(-0.25t + ln(14)) = e^ln(14) e^(-0.25t) = 14 e^(-0.25t)
Since we are only interested in the positive value of D, we can drop the absolute value sign:
D = 14 e^(-0.25t)
Now we can solve for x by setting D = 8:
8 = 14 e^(-0.25x)
Dividing both sides by 14, we get:
e^(-0.25x) = 8/14 = 4/7
Taking the natural logarithm of both sides, we get:
ln(e^(-0.25x)) = ln(4/7)
-0.25x = ln(4/7)
x = -4 ln(4/7) / 0.25
x ≈ 6.21
Therefore, it will take about 6.21 minutes for the balloon to shrink to a diameter of 8 feet.

statistics are often calculated with varying amounts of input data. write a program that takes any number of non-negative integers as input, and outputs the max and average. a negative integer ends the input and is not included in the statistics. assume the input contains at least one non-negative integer.Output the average with two digits after the decimal point followed by a newline, which can be achieved as follows:
System.out.printf("%.2f\n", average);
Ex: When the input is:
15 20 0 3 -1
the output is:
20 9.50
The average with two digits after the decimal point followed by a newline is 7.4
An integer is a whole number, either positive or negative, that does not have any decimal points. Non-negative integers are those that are greater than or equal to zero.
To write such a program, we can use a loop to continuously read in integers from the user until a negative integer is entered. We then ignore the negative integer and calculate the maximum and average of the non-negative integers that were entered.
The maximum is simply the largest integer in the set. We can use a variable to keep track of the largest integer as we read in the input. At the end of the loop, the variable will hold the maximum value.
The average is the sum of all the integers divided by the total number of integers.
We add each non-negative integer to the sum and increment the count. At the end of the loop, we divide the sum by the count to get the average.
To output the average with two digits after the decimal point, we can use the printf method, which allows us to format our output. The format string "%.2f\n" specifies that we want to output a floating-point number with two decimal places followed by a newline character.
=> (15 + 20 + 0 + 3 - 1) / 5 = 7.4
In summary, a program that takes any number of non-negative integers as input, and outputs the max and average can be written using a loop, variables to keep track of the maximum, sum, and count, and the printf method to format the output. Understanding the basics of integers and how to perform calculations with them is essential for programming and statistical analysis.

How to calculate the angles of the rectangle.The angles m∠MON and m∠LOM form one of the interior angles of a rectangle, hence they are complementary as they add up to 90°.
we shall solve for x as follows:
2x + 7x + 9 = 90

9x = 90 - 9 {subtract 9 from both sides}
9x = 81
x = 81/9 {divide through by 9}
x = 9
m∠MON = 7(9) + 9 = 72°
m∠LOM = 2(9) = 18°
The angles m∠LOM and m∠POQ are vertical angles formed by the two straight lines MA and LP, hence;
m∠LOM = m∠POQ = 18°
