When the tank is tilted, the water level reaches the midpoint of the 60 cm side, which is 30 cm from the bottom of the tank. This means that the height of the water is 30 cm.

To find the depth of the water when the tank is returned to its horizontal position, we need to use the concept of similar triangles. The two triangles formed by the water level and the sides of the tank are similar, because they have the same angles.

Let x be the depth of the water in centimeters when the tank is returned to its horizontal position. Then we have:

(40 - x) / 60 = 30 / 50

Simplifying this equation, we get:

40 - x = 36

x = 4

Therefore, the depth of the water in the fish tank when it is returned to its horizontal position is 4 cm.

The price per foot of the 2-yard rope is $6.36.

To find the price per foot of the 2-yard rope, we need to first convert the length to feet. Since there are 3 feet in a yard, a 2-yard rope is equal to 6 feet.

Next, we divide the total cost of the rope ($22.86) by the length of the rope in feet (6 feet) to get the price per foot:

$22.86 ÷ 6 = $3.81 per yard

To convert this to the price per foot, we divide $3.81 by 3 (since there are 3 feet in a yard):

$3.81 ÷ 3 = $1.27 per foot

Therefore, the price per foot of the 2-yard rope is $1.27 x 5 = $6.36.

The ladder reaches the height of approximately 16.03 feet up the wall. (Rounded to the nearest hundredth of a foot)

We can use trigonometry to solve this problem. Let h be the height up the wall that the ladder reaches, and let θ be the angle that the ladder makes with the ground. We know that the length of the ladder (hypotenuse) is 16 feet and the angle θ is 78 degrees.

We can use the trigonometric function tangent (tan) to find the height h:

tan(θ) = opposite/adjacent

In this case, the opposite side is the height h, the adjacent side is the distance from the ladder to the wall (which is the same as the distance from the wall to Lauren), and the angle θ is 78 degrees. So we have:

tan(78°) = h/x

where x is the distance from the ladder to the wall. Solving for h, we get:

h = x * tan(78°)

We don't know the value of x, but we can use the fact that the ladder is 16 feet long to find it. Using the Pythagorean theorem, we have:

x^2 + h^2 = 16^2

Substituting h = x * tan(78°), we get:

x^2 + (x * tan(78°))^2 = 16^2

Simplifying, we get:

x = 16 / √(1 + tan^2(78°))

x ≈ 3.83 feet

Finally, we can substitute x into our equation for h:

h = x * tan(78°)

h ≈ 16.03 feet

Therefore, the ladder reaches approximately 16.03 feet up the wall. Rounded to the nearest hundredth of a foot, the answer is 16.03 feet.

a. After 10 minutes of hiking, Kiran will have covered a distance of:

distance = rate × time

distance = 0.04 mile/min × 10 min

distance = 0.4 mile

So, his remaining distance on the trail will be:

remaining distance = total distance - covered distance

remaining distance = 1.8 mile - 0.4 mile

remaining distance = 1.4 miles

Therefore, Kiran's remaining distance on the trail after 10 minutes of hiking is 1.4 miles.

b. We can use the same formula to find out how far Kiran will have walked after a certain amount of time:

distance = rate × time

We know that Kiran walks at a rate of 0.04 mile a minute, and we want to find out how much time it will take him to cover the remaining distance of 0.2 mile. So we can rearrange the formula to solve for time:

time = distance / rate

time = 0.2 mile / 0.04 mile/min

time = 5 minutes

Therefore, Kiran will have 0.2 mile left on the trail after 5 minutes of walking.

Therefore, the number of ways to choose a committee of size 10 with at least 2 men is: 961379655

We are to find the number of ways to choose a committee of size 10 with at least 2 men if there are 30 women in the club and 20 men in the club using set difference. We can use the following formulas: (1) A set difference B = {elements of A that are not in B} (2) The number of ways to choose k elements from n elements is represented by nCk.

(3) The complement of an event E is the set of all outcomes in the sample space that are not included in the outcome of E.(4) If E is an event, then P(E) represents the probability of E happening.(5) P(E') + P(E) = 1 (where E' is the complement of E).

To choose a committee of size 10 with at least 2 men, we can first find the total number of committees possible (which includes committees with 0, 1 or 2 men) and then subtract the committees that do not have at least 2 men. So, the total number of ways to choose a committee of size 10 is 50C10. Using the formula nCk = n!/k!(n-k)!, we can write it as follows: 50C10 = 50! / 10!40! = 10272278170.

The number of ways to choose a committee of size 10 with no men is 30C10.Using the formula nCk = n!/k!(n-k)!, we can write it as follows:30C10 = 30! / 10!20! = 30045015. The number of ways to choose a committee of size 10 with exactly 1 man is (20C1) * (30C9).Using the formula nCk = n!/k!(n-k)!, we can write it as follows:(20C1) * (30C9) = 20! / 1!19! * 30! / 9!21! = 47152200.

The number of ways to choose a committee of size 10 with exactly 2 men is (20C2) * (30C8). Using the formula nCk = n!/k!(n-k)!, we can write it as follows:(20C2) * (30C8) = 20! / 2!18! * 30! / 8!22! = 47502000. Therefore, the number of ways to choose a committee of size 10 with at least 2 men is:50C10 - 30C10 - (20C1) * (30C9) - (20C2) * (30C8)10272278170 - 30045015 - 47152200 - 47502000 = 961379655  Ways.

What is trapezoid?

In geometry, a trapezoid is a four-sided polygon that has at least one pair of parallel sides. The parallel sides of a trapezoid are called bases, while the non-parallel sides are called legs.

The image below appears to be a trapezoid with vertices at A(2,2), B(4,5), C(6,5), and D(8,2). There are several ways to obtain this image, but here are two possible methods:

Method 1: Plotting the Points

One way to obtain the image is to plot the points A, B, C, and D on a coordinate plane, and then connect them in the correct order to form the trapezoid. Here are the steps:

Draw a coordinate plane with x and y axes.

Plot the point A at (2,2).

Plot the point B at (4,5).

Plot the point C at (6,5).

Plot the point D at (8,2).

Connect the points A, B, C, and D in the order ABDC to form the trapezoid.

Method 2: Transformations

Another way to obtain the image is to start with a reference trapezoid with known vertices, and then apply a sequence of transformations to obtain the desired trapezoid. Here are the steps:

Start with a reference trapezoid with vertices at (0,0), (2,3), (4,3), and (6,0). This trapezoid has the same shape as the desired trapezoid, but is located in a different position on the coordinate plane.

Translate the reference trapezoid 2 units to the right and 2 units up by adding (2,2) to each vertex. This results in a trapezoid with vertices at (2,2), (4,5), (6,5), and (8,2), which is the desired trapezoid.

(Optional) Rotate or reflect the trapezoid as desired to obtain different orientations or symmetries.

The average of the other two numbers is 16.

This is because the average of 8 numbers is 14, and the average of 6 of those numbers is 12. Therefore, to find the average of the remaining two numbers, you need to find the difference between the average of 8 and the average of 6.

The difference between 14 and 12 is 2. Therefore, if the average of 6 is 12, the average of the remaining two numbers must be 12 + 2 = 16.

To solve this question, you need to use the fact that the average of 8 numbers is 14, and the average of 6 of those numbers is 12. The average of 8 numbers is the sum of all 8 numbers divided by 8. Therefore, if the average of 8 numbers is 14, the sum of all 8 numbers must be 14x8 = 112.

Similarly, the average of 6 numbers is 12, so the sum of those 6 numbers must be 12x6 = 72. The difference between these two sums is 112-72 = 40. This is the sum of the remaining two numbers.

d*tan(θ1) = (d+x)*tan(θ2)

d*(tan(θ1)-tan(θ2)) = x*tan(θ2)

d = x*tan(θ2)/(tan(θ1)-tan(θ2))

Substituting the given values, we get:

d = x*tan(32°)/(tan(6°)-tan(32°))

This is true because coordinates (0.8, 0.6) satisfy the equation x² + y² = 1.

The approximate angle measures needed to intersect at (0.8, 0.6) and each of these new points is 38.66 degrees.

Other points on the unit circle are (0.6, 0.8), (-0.8, 0.6), (-0.6, -0.8), and (0.8, -0.6).

The coordinates (0.8, 0.6) lie exactly on the unit circle because they satisfy the equation x² + y² = 1, which defines the unit circle. Plugging in x = 0.8 and y = 0.6 gives 0.8² + 0.6² = 1, which is true.

To find the angle measure needed to intersect at (0.8, 0.6) and each of the new points, we can use the inverse tangent function. If we let theta be the angle between the positive x-axis and the line connecting the origin and the point of intersection, then we can use the equation tan(theta) = y/x to find the angle. For example, to find the angle needed to intersect at (0.8, 0.6) and (1, 1), we have tan(theta) = 0.6/0.8, which simplifies to theta = arctan(0.6/0.8) ≈ 38.66 degrees.

the probability that the difference between the sample mean and the true population mean will not exceed 0.5 inch is 0.9544

We can use the central limit theorem to approximate the distribution of the sample mean. Since the sample size is large (n=100), the sample mean follows approximately a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size (i.e., 2.5/sqrt(100) = 0.25).

Let X be the sample mean, then we want to find P(|X - μ| ≤ 0.5), where μ is the population mean.

Using the standard normal distribution, we can standardize X as follows:

Z = (X - μ) / (σ / sqrt(n)) = (X - μ) / 0.25

So we want to find P(|Z| ≤ 2), where Z follows a standard normal distribution.

Using a standard normal distribution table or calculator, we find that P(|Z| ≤ 2) = 0.9544.

There are 1960 different ways to distribute 8 identical pieces of candy to the five children, where the twins get an equal amount of candy.

First, distribute the candy to the twins.

Split the 8 pieces of candy into two equal parts for the twins using combinations:

C(8, 4)

This means selecting 4 pieces of candy from the 8 identical pieces for one twin, and the remaining 4 pieces will automatically go to the other twin.

C(8, 4) is calculated as:

[tex]^8C_4 = \dfrac{8!}{4!(8-4)!}[/tex]

     = 8! / (4! * 4!)

     = (8 * 7 * 6 * 5) / (4 * 3 * 2 * 1)

     = 70

Now, you have distributed 4 pieces of candy to each of the twins. Y

In this case, you have 6 pieces of candy to distribute among 3 children, and you can use two dividers (bars) to separate the candy for each child.

This can be represented as:

OO|OO|OO

The two bars split the 6 pieces of candy into three sections for the three children.

So, you have C(6 + 2, 2) ways to distribute the remaining candy:

[tex]^{6+2}C_2 = \dfrac{8!}{2!(8-2)!}[/tex]

         = 8! / (2!(8 - 2)!)

         = 8! / (2! * 6!)

         = (8 * 7) / (2 * 1)

         = 28

Now, the total number of ways to distribute the candy

Total ways = C(8, 4) * C(8, 2) = 70 * 28 = 1960

Step-by-step explanation:

let's assume this triangle's sides are a,b and c.

we know this equation: [tex]a+b > c > |a-b|\\c+b > a > |c-b|\\a+c > b > |a-c|\\a=6\\b=7\\c=9\\13 > 9 > 1--- > which is true\\16 > 6 > 2----- > which is true as well\\15 > 7 > 3------ > it is true,too\\all of this equations are true so, this is a triangle[/tex]

Answer:

To find the simple interest on a principal of $600 at a rate of 2% for a time period of 2 years, we can use the formula:

Simple Interest = (Principal * Rate * Time)

where Rate is the annual interest rate as a decimal, and Time is the time period in years.

In this case, we have:

Principal = $600

Rate = 0.02 (2% expressed as a decimal)

Time = 2 years

So, the formula becomes:

Simple Interest = ($600 * 0.02 * 2)

= $24

Therefore, the simple interest on a principal of $600 at a rate of 2% for 2 years is $24.

Answer: To find the mean of this data set, we need to add up all the heights of lilies and divide by the total number of lilies. We can estimate the heights from the line plot:

There is 1 lily at a height of 18 inches.

There is 1 lily at a height of 19 inches.

There are 2 lilies at a height of 20 inches.

There are 2 lilies at a height of 21 inches.

There are 3 lilies at a height of 22 inches.

There are 0 lilies at a height of 23 inches.

There is 1 lily at a height of 24 inches.

To calculate the mean, we need to multiply each height by the number of lilies at that height, then add up these products, and divide by the total number of lilies:

(1 x 18) + (1 x 19) + (2 x 20) + (2 x 21) + (3 x 22) + (0 x 23) + (1 x 24)

Copy code

                    10

= (18 + 19 + 40 + 42 + 66 + 0 + 24) / 10

= 209 / 10

= 20.9

Therefore, the mean height of lilies in this data set is 20.9 inches. The answer is (B) 20.9.
