The remaining angles of the parallelogram are 60°, 120°, and 120°.

In a parallelogram, opposite angles are equal and consecutive angles are supplementary. This means that:

- Angle A = Angle C
- Angle B = Angle D
- Angle A + Angle B = 180°
- Angle C + Angle D = 180°

Given that angle A = 60°, we can use the above properties to find the remaining angles:

- Angle C = Angle A = 60°
- Angle B + Angle A = 180° => Angle B + 60° = 180° => Angle B = 180° - 60° = 120°
- Angle D = Angle B = 120°

Therefore, the remaining angles of the parallelogram are 60°, 120°, and 120°.

Answer:

f(x) = (x + 3)(x - 4) / (x + 3)

Step-by-step explanation:

In order for a rational function to have a hole at x = 4 and a vertical asymptote at x = -3, the denominator must be equal to zero at x = 4 and the numerator must be equal to zero at x = -3. This can be accomplished with the following expression:

f(x) = (x + 3)(x - 4) / (x + 3)

Step-by-step explanation:

1 ft = 12 in

so,

36 in = 36/12 = 3 ft

24 in = 24/12 = 2 ft

therefore, the area of the rectangle is

3×2 = 6 ft²

Answer:

31.08 billion

Step-by-step explanation:

If the shoe sales for a certain company were 25.9 billion, and the sales are projected to increase by 20%, we can calculate the projected amount by adding the increase to the original sales:

Projected sales = Original sales + (Increase percentage × Original sales)

Plugging in the values we have:

Projected sales = 25.9 billion + (0.20 × 25.9 billion)

Projected sales = 25.9 billion + 5.18 billion

Projected sales = 31.08 billion

Therefore, the projected amount of shoe sales for the company is 31.08 billion.

Answer: The estimated probability of generating a 3 using the random number generator is 1/3, since there are 3 possible outcomes and each is equally likely.

The actual probability of generating a 3 is also 1/3, since the generator is equally likely to generate any of the 3 possible integers.

Therefore, the difference between the estimated and actual probability of generating a 3 is:

1/3 - 1/3 = 0

So there is no difference between the estimated and actual probability of generating a 3.

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 equation 4x - 3y > 12 can be graphed by finding two points that satisfy the inequality. For example, you could use the points (0, 4) and (3, 0). Then, you can plot the points on a graph and draw the line that passes through them. This line is the graph of the inequality. You can also put the equation into slope-intercept form by rearranging the equation to y = (4/3)x - (4/3). The graph of y = (4/3)x - (4/3) is the same as the graph of the original inequality.

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.

As a result, if the two angles' measurements are (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.

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.

The fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is 2/5

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.
