Cleopatra and her brother, Ptolemy, each have cylindrical water clocks (so they drain uniformly), but their clocks have different heights and diameters. Cleopatra’s clock drains from full down to empty in 4 hours and Ptolemy’s does so in 5 hours. After two hours of draining, the water height in both clocks is the same. What fraction of the height of Cleopatra’s clock is the height of Ptolemy’s? After each has been draining for three hours, what fraction of the water height of Ptolemy’s clock is equal to the water height of Cleopatra’s?
The fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is 2/5
What is a Fraction?A fraction is a mathematical concept that represents a part of a whole or a ratio between two quantities. It is typically written in the form of a numerator over a denominator, separated by a horizontal line, such as 1/2, 3/4, or 7/8.
Given that the volume of cylinder = πr^2h
Let's denote the height and radius of Cleopatra's water clock as h_c and r_c, respectively, and the height and radius of Ptolemy's water clock as h_p and r_p, respectively.
Since both clocks drain uniformly, we can use the formula for the volume of a cylinder to relate the height and radius of each clock to the time it takes to drain:
Volume of Cleopatra's clock = [tex]\pi r^2_ch_c[/tex]
Volume of Ptolemy's clock = [tex]\pi r^2_ph_p[/tex]
Since Cleopatra's clock drains in 4 hours, the rate of draining is (Volume of Cleopatra's clock) / (4 hours), and similarly for Ptolemy's clock.
We are given that after 2 hours of draining, both clocks have the same water height.
Therefore, we can set the two rates of draining equal to each other and solve for the ratio of heights:
(Volume of Cleopatra's clock) / (4 hours) = (Volume of Ptolemy's clock) / (5 hours)
hc/hp = [tex](r_p/r_c)^2 * (5/4)[/tex]
After two hours of draining, the water height in both clocks is the same, so we can set the volume of water in each clock equal to each other:
[tex]r^2_ch_c/2 = r^2_ph_p[/tex]
Now, we can solve for the ratio of water heights after each clock has been draining for three hours:
Water height in Cleopatra's clock after 3 hours = [tex]h_c - (3/4)h_c = (1/4)h_c[/tex]
Water height in Ptolemy's clock after 3 hours = [tex]h_p - (3/5)h_p = (2/5)h_p[/tex]
hp= 1/10
Therefore, the fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is:
hp/hc = 1/10/(1/4) = 2/5
And the fraction of the water height of Ptolemy's clock that is equal to the water height of Cleopatra's clock after each has been draining for three hours is:
hc/(2/5)hp = (1/4)/(2/5)(1/10)
= 5/4.
Hence,
The fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is: 2/5
The fraction of the water height of Ptolemy's clock that is equal to the water height of Cleopatra's clock after each has been drained for three hours is: 5/4.

Find the principal argument Arg z when (a) -2/(1 + √3i);
(b) (√3 - i)^6.
The required answer for the expression -2/(1 + √3i) is Arg (z) = 2π/3. The required answer for the expression (√3 - i)⁶ is Arg (z) = π.
The principal argument is the angle created by the line joining the origin, z, and the positive real axis. A complex number with the expression z = x + i y has the argument form [tex]\text{Arg}(z)=\tan^{-1}\frac{y}{x}[/tex] when x > 0.
a) Given z=2/(1 + √3i). First, simplify the given expression,
[tex]\begin{aligned}\frac{-2}{1+i\sqrt{3}}&=\frac{-2}{1+i\sqrt{3}}\times\frac{1-i\sqrt{3}}{1-i\sqrt{3}}\\&=\frac{-2(1-i\sqrt{3})}{1^2-(i\sqrt{3})^2}\\&=\frac{-2-2\sqrt{3}i}{4}\\&=\frac{-1}{2}-\frac{\sqrt{3}}{2}i\end{aligned}[/tex]
Now find, the arg of the above expression. Here, x is -1/2 and y is√3/2. We get,
[tex]\begin{aligned}\mathrm{Arg}(z)&=\tan^{-1}\frac{y}{x}\\&=\frac{\frac{\sqrt{3}}{2}}{\frac{-1}{2}}\\&=\tan^{-1}(-\sqrt{3})\\&=\frac{2\pi}{3}\end{aligned}[/tex]
The required answer is Arg (z) = 2π/3.
b) Given (√3 - i)⁶. We know that,
[tex]\begin{aligned}\sqrt{3}-i&=2\left(\frac{\sqrt{3}}{2}-\frac{1}{2}i\right)\\ &=2\times e^{\left(-\frac{\pi}{6}i\right)\end{aligned}[/tex]
Then,
[tex]\begin{aligned}(\sqrt {3} -i)^6&=2^6\times e^{-\pi i}\\&=-2^6\end{aligned}[/tex]
Here, x is -64 and y is 0. Then, tan⁻¹ (0) = 0 = π.
The required answer is Arg (z) = π.

the measure of 2 angles are (3y+11) and (11 y+15). What is the value of y if the angles are congruent
As a result, if the two angles' measurements are (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.
What is angle?An angle is a geometric figure formed by two rays that have a common endpoint, called the vertex. The rays are also known as the sides or legs of the angle. Angles are typically measured in degrees, with a full circle measuring 360 degrees. Angles can also be measured in radians, which are another unit of angular measurement used in mathematics and physics. One radian is equal to the angle subtended by an arc of a circle that has a length equal to the radius of the circle. The size of an angle is determined by the amount of rotation that occurs between the two rays. This is typically measured relative to the positive x-axis, with counterclockwise rotations being considered positive and clockwise rotations being considered negative. Angles are used in a wide range of mathematical and scientific applications, including geometry, trigonometry, physics, engineering, and architecture. They are also used in many everyday situations, such as measuring the size of an opening or the angle of incidence of sunlight on a surface.
Here,
If the two angles are congruent, then they must have the same measure.
So we can set the expressions for the measures of the two angles equal to each other and solve for y:
3y + 11 = 11y + 15
Subtracting 3y from both sides:
11 = 8y + 15
Subtracting 15 from both sides:
-4 = 8y
Dividing both sides by 8:
y = -1/2
Therefore, if the measure of the two angles is (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.

what is 2pm in military time?
To convert 2 pm in the 12-hour clock format to military time, we add 12 to the hour to get 14, and the minutes remain the same, resulting in a military time of 14:00pm.
In military time, the day is divided into 24 hours, starting from midnight (00:00 hours) and ending at 23:59 hours. Each hour is numbered from 0 to 23, instead of repeating the numbers from 1 to 12 twice in a day.
Military time uses a four-digit number to represent the time, where the first two digits represent the hour and the last two digits represent the minutes.
To convert 2 pm in the 12-hour clock format to military time, we need to add 12 to the hour since 2 pm is in the afternoon and military time does not use the "am" or "pm" designations.

•The remaining students travel to school by bus.
How many students travel to school by bus?
a.651
6.837
c.1209
d.1443
Answer:
a. 651
Step-by-step explanation:
To solve the problem, you can start by finding out how many students bike or walk to school by multiplying the total number of students by the percentage that bike or walk:
1860 x 0.45 = 837
Next, you can subtract the number of students who drive to school to find out how many students travel by bus:
1860 - 837 - 372 = 651
Therefore, the answer is 651, so the option (a) is correct.
Answer:
a. 651
Step-by-step explanation:
We first need to find the number of students that bike or walk.
We can do this by plugging the numbers into this equation:
[tex]\frac{is}{of} = \frac{percent}{100}[/tex]
We know that the percent is 45, and we know the total amount of students, 1860, so we are solving for is.
[tex]\frac{x}{1860} = \frac{45}{100}[/tex] where x = is.
To solve this, we cross multiply:
1860(45) = 100x
83,700 = 100x
837 = x
Now we know that 837 students bike or walk, and 372 drive.
We can calculate how many students travel by bus by subtracting these numbers from the total number of students, 1860.
1860 - 837 - 372 = 651
Therefore, 651 students travel to school by bus.

The single natural logarithm for the expression 4 + ln 2 - ln 4 is ln(2). So, correct option is A.
To express 4 + ln 2 - ln 4 as a single natural logarithm, we can use the properties of logarithms to combine the terms.
First, we can use the rule that ln(a) - ln(b) = ln(a/b) to simplify ln 2 - ln 4:
ln 2 - ln 4 = ln(2/4) = ln(1/2)
Now, we can rewrite the expression as:
4 + ln(1/2)
We can use another logarithmic property, ln(a) + ln(b) = ln(ab), to write this as:
4 + ln(2^(-1))
Simplifying further:
4 - ln(2)
Therefore, 4 + ln 2 - ln 4 can be expressed as a single natural logarithm of:
ln(2^2 / 2) = ln(2)
So, the answer is (a) ln 2.
In general, when simplifying expressions involving logarithms, it's helpful to remember the logarithmic properties and rules, such as the product, quotient, and power rules, as well as the fact that ln(e) = 1.
