To find the measure of an angle in a triangle that is isosceles, you can use the fact that the two equal sides of the triangle are congruent to each other.  The measure of each of these angles can be found by subtracting the measure of the third angle from 180 degrees.

Determine which two sides of the triangle are equal in length (these are called the "congruent sides").

Find the measure of the angle opposite one of the congruent sides. This angle is called the "base angle."

Subtract the measure of the base angle from 180 degrees. This will give you the measure of the other two angles in the triangle (since the three angles in any triangle must add up to 180 degrees).

For example, if the measure of the base angle is x degrees, then the measure of the other two angles would be (180-x) degrees.

The measure of angles in an isosceles triangle can be found using the Triangle Angle Sum Theorem. This theorem states that the sum of the angles in any triangle is 180 degrees. Therefore, if you know two of the angles in the triangle, you can find the third angle by subtracting the sum of the two known angles from 180.

To find the measure of an angle in a triangle isosceles, you can use the Triangle Angle Sum Theorem. This theorem states that the sum of the angles in any triangle is 180 degrees. Therefore, if you know two of the angles in the triangle, you can find the third angle by subtracting the sum of the two known angles from 180.

Let's look at an example. Suppose you have an isosceles triangle and you know that two of its angles measure 50 degrees and 60 degrees. To find the measure of the third angle, you would subtract 110 (the sum of the two known angles) from 180. This gives you 70 degrees as the measure of the third angle.

In addition to the Triangle Angle Sum Theorem, you can also use the Isosceles Triangle Theorem to find the measure of an angle in an isosceles triangle. The Isosceles Triangle Theorem states that the angles opposite the two equal sides of an isosceles triangle are equal. This means that if you know one of the angles in the triangle, you can determine the measure of the other two angles, since they will both be equal to the measure of the known angle.

Answer:

We can start by finding the total number of learners who participate in jogging and cycling by multiplying the ratio by the total number of learners. Let's say x is the number of learners who jog. Then, the number of learners who cycle is 2x.

The total number of learners who jog and cycle is 125, so:

x + 2x = 125

3x = 125

x = 125 / 3

x = 41.67

Since x represents the number of learners who jog, there are 41.67 learners who jog. Since the number of learners who cycle is 2x, there are 2 * 41.67 = 83.33 learners who cycle.

Since these are whole numbers of learners, we round up to the nearest whole number to get 42 joggers and 83 cyclists.

The number of students participating in each of the sports will be 75 for jogging and 50 for cycling.

Solution:

Let's assume that the number of students who participated in jogging will be 3x and those in cycling will be 2x

Given,

3x + 2x = 125

5x = 125

So, x = 25

Therefore, the number of students in jogging will be 3*25 = 75 and in cycling will be 2*25 = 50

The equivalent expression that is most useful to find the year where the population is minimum is, 8(x-11)^2+56

A quadratic equation is an algebraic expression of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a, b are the coefficients, x is the variable, and c is the constant term

Given an expression that represents the population from 1998 to 2018,

\(8x^2-176x+1024\)

Let,

\(y=8x^2-176x+1024\)

Which is an upward parabola,

Since, the minimum value of an upward parabola,

\(y=a(x-h)^2+k\)

is find at x = h,

From equation (1),

\(y=8x^2-176x+1024\)

\(y=8x^2-176x+968-968+1024\)

\(y=8(x^2-22x+121)+56\)

\(y=8(x-11)^2+56\)

By comparing,

The population is minimum at x = 11. ( that is after 11 years since 1998 )

Hence, the equivalent expression that is most useful to find the year where the population is minimum is,8(x-11)^2+56

(1) The general solution to the differential equation (2xy^3 - excosy)dx + (3x^2y^2 + exsiny)dy = 0 is given by x^2y^3 - excosy + C = 0 where C represents the constant of integration. (2) For the differential equation (y + x^2 - y^2 - 2y)dx + (x + x^2 - y^2/2x)dy = 0

(1) To solve the differential equation (2xy^3 - excosy)dx + (3x^2y^2 + exsiny)dy = 0, we need to check if it is exact. We can do this by verifying if the partial derivative of the term with respect to y is equal to the partial derivative of the term with respect to x.

Taking the partial derivative of the term with respect to y, we get:

∂/∂y(2xy^3 - excosy) = 6xy^2 + exsiny

Taking the partial derivative of the term with respect to x, we get:

∂/∂x(3x^2y^2 + exsiny) = 6xy^2 + exsiny

Since the partial derivatives are equal, the differential equation is exact.

To find the solution, we integrate the term with respect to x, treating y as a constant:

∫(2xy^3 - excosy)dx = x^2y^3 - excosy + C(y)

Here, C(y) represents the constant of integration with respect to y.

Next, we differentiate the integrated term with respect to y and equate it to the term involving dy:

∂/∂y(x^2y^3 - excosy + C(y)) = 3x^2y^2 - exsiny + C'(y) = 3x^2y^2 + exsiny

From this, we can conclude that C'(y) = 0, which means C(y) is a constant.

Therefore, the general solution to the differential equation is:

x^2y^3 - excosy + C = 0

(2) To solve the differential equation (y + x^2 - y^2 - 2y)dx + (x + x^2 - y^2/2x)dy = 0, we'll follow a similar approach.

We check if the differential equation is exact by comparing the partial derivatives:

∂/∂y(y + x^2 - y^2 - 2y) = 1 - 2y - 2

∂/∂x(x + x^2 - y^2/2x) = 1 + 2x

The partial derivatives are not equal, indicating that the equation is not exact. In this case, we can use an integrating factor to make it exact.

The integrating factor is given by:

μ = e^(∫(∂/∂y - ∂/∂x)dy) = e^(∫(-1 - 2x)dy) = e^(-y - 2xy)

Multiplying the entire equation by μ, we get:

(e^(-y - 2xy))(y + x^2 - y^2 - 2y)dx + (e^(-y - 2xy))(x + x^2 - y^2/2x)dy = 0

Simplifying and rearranging, we have:

(e^(-y - 2xy))(x + x^2 - y^2/2x - y - 2xy + xy + x^3 - y^2/2)dx + (e^(-y - 2xy))dy = 0

(e^(-y - 2xy))(x^3 - 3xy + x - y^2/2)dx + (e^(-y - 2xy))dy = 0

The year-2 CPI is 102, and the rate of inflation from year 1 to year 2 is 2%.

To calculate the rate of inflation and the Consumer Price Index (CPI) change from year 1 to year 2, we need to follow these steps:

Step 1: Calculate the inflation rate:

Inflation Rate = (Year 2 CPI - Year 1 CPI) / Year 1 CPI

Step 2: Calculate the Year 2 CPI:

Year 2 CPI = (Year 2 Basket Price / Year 1 Basket Price) * 100

Let's calculate the values:

Year 1 Basket Price = $25.00

Year 2 Basket Price = $25.50

Step 1: Calculate the inflation rate:

Inflation Rate = ($25.50 - $25.00) / $25.00

Inflation Rate = $0.50 / $25.00

Inflation Rate = 0.02 or 2%

Step 2: Calculate the Year 2 CPI:

Year 2 CPI = ($25.50 / $25.00) * 100

Year 2 CPI = 1.02 * 100

Year 2 CPI = 102

Therefore, the year-2 CPI is 102, and the rate of inflation from year 1 to year 2 is 2%.

The coordinates of the vertex of the quadratic function are given as follows:

(-3, -24).

Hence the quadratic function is given as follows:

y = a(x + 3)² - 24.

In which a is the leading coefficient.

When x = 3, y = 0, hence the leading coefficient a is obtained as follows:

0 = a(3 + 3)² - 24

There are 39% of all the people on the trip are female students on a school trip.

One to fifteen teachers are assigned to every hundred students.

and there are 7:5 more female students than male students.

Let's say there are x teachers. Students multiply by 15 as a result.

Take the ratio of male to female as 7 years for the male and 5 years for the female.

The total student trip is made up of both male and female pupils.

Thus,

15x = 7y + 5y

15x = 12y

Answer:

Step-by-step explanation:

Since Jess can drive 200 miles on a 1/2 of a tank of gas that must mean he can drive 100 miles with his gas tank only 1/4 full. Since he needs to know how far he can drive with his gas 3/4 of the way full he would just add 200 miles to 100 miles and get 300 miles.

You figure this out by dividing 200 miles by 2 since it is a half way full and you just need to half the amount of miles to get how many miles it is for a fourth of the way full. You would need to find out how much it is for a fourth of the way full since it only says Jess can drive 200 miles on a 1/2 tank of gas. However we need to find out how far he can drive with 3/4 tank of gas. Which you know that you need to find out how much it is for a fourth of a tank of gas or 1/4 since 1/2 is also equal to 2/4 and 1/4 plus 2/4 is equal to 3/4.

To test the difference between two independent population means with two samples, you need to calculate the degrees of freedom (df). Here's a step-by-step explanation:

1. Identify the sample sizes: The first sample has a size of 28 (n1 = 28), and the second sample has a size of 27 (n2 = 27).

2. Calculate the degrees of freedom for each sample: For each sample, subtract 1 from the sample size. For sample 1, df1 = n1 - 1 = 28 - 1 = 27. For sample 2, df2 = n2 - 1 = 27 - 1 = 26.

3. Combine the degrees of freedom: Add the degrees of freedom from each sample together to get the total degrees of freedom: df = df1 + df2 = 27 + 26 = 53.

In this case, you will use 53 degrees of freedom to find the critical value for testing the difference between the two independent population means.

Answer:

Triangle ABC is congruent to triangle DFE.

Let L be the average number of customers in the system (i.e., the length of the line), λ be the arrival rate, W be the average time each customer spends in the system (i.e., the total time in the line plus the service time), and μ be the service rate. Then:

L = λW

We know that the arrival rate is λ = 7/hour and the service rate is μ = 16/hour. We also know that the average waiting time in the line is 19 minutes, or W = 19/60 hours. We can calculate W as follows:

W = Wq + 1/μ

where Wq is the average time a customer spends waiting in the line. Since we don't know the distribution of the arrival and service times, we cannot directly calculate Wq. However, we can use Little's Law again to relate the average number of customers in the waiting line to the average waiting time in the line:

Lq = λWq

where Lq is the average number of customers waiting in the line. We can then substitute this expression for Lq into the equation for W:

W = Lq/λ + 1/μ

W = (λWq)/λ + 1/μ

W = Wq + 1/μ

Solving for Wq, we get:

Wq = W - 1/μ

Wq = 19/60 - 1/16

Wq = 0.2667 hours

Now we can use Little's Law to calculate the length of the line:

L = λW

L = 7/hour x 0.2667 hours

L = 1.8667

Therefore, the length of the line is approximately 1.87 customers. Note that this is an average value, and the actual length of the line can fluctuate above or below this value due to random arrivals and service times.
