b = 45 x 9 what is b ?

Answer:

See answer below

Step-by-step explanation:

In this case, this is just sum, substraction and divisions using the properties or the signus. This is just basic operations using the negative and positive numbers.

To do this easily you just have to remember the following:

1. Numbers with same sign, must be summed and put the sign that have either number.

2. Numbers with different sign, must be substracted and then put the sign of the highest number.

3. If you have a multiplication or division:

- Same signs multiplied or dividied (Either positive or negative), result always positive.

- Different signs multiplied or dividied (positive and negative), result always negative.

Following this simple rules, you'll be able to solve almost any exercise of this.

Now, according to the rules above, let's solve the exercises:

A. (-13) + (-7)

In this case, you have two negative numbers, and one positive sign between them. Apply the 3rd rule. The negative sign remains and then:

-13 - 7

Now 1st rule applied, sum the numbers and let the same sign:

-13 - 7 = -20.

B. (-15) - (-15) = 0.

Applying 3rd rule and then 2nd rule, we have a subtration of -15 + 15.

C. (2) * (-13) = -26

Applying the 3rd rule, we have positive and negative, result always negative.

D. (-44) / 11 = -4

3rd rule applied.

E. (-3) + (-5) + 8 + 25 = 31

Applied 3rd and 1st rule.

I don't understand the f, but you can use the rules here and get the final answer of that one.

Th number of tiles the students need is 512.

The first step is to convert feet to inches

1 feet = 12 inches

The next step is to convert the dimensions of room 111 to inches

8 x 12 = 96 inches

16 x 12 = 192 inches

Now, determine the area of the room and the tiles.

Area = length x width

Area of the room = 96 x 192 = 18,432 in²

Area of the tile = 6 x 6 = 36 in²

Number of tiles needed = 18,432 in² / 36 in² =512

False. The intercepted arc is actually twice the measure of the inscribed angle only if the inscribed angle is an angle at the center. If the inscribed angle is not at the center, the intercepted arc will have a different measure.

So, in general, the relationship between the measure of the intercepted arc and the inscribed angle it was created from depends on the location of the inscribed angle in the circle. This is a long answer, but it provides a detailed explanation of the relationship between the intercepted arc and the inscribed angle in different scenarios.

AN intercepted arc is twice the measure of the inscribed angle it was created from.
In a circle, when an inscribed angle is formed by two chords, it intercepts an arc on the circle. According to the Inscribed Angle Theorem, the measure of the inscribed angle is half the measure of the intercepted arc. Therefore, the intercepted arc is indeed twice the measure of the inscribed angle.

The first relationship states that for any positive value of 'a', 'a' raised to the power of 2 is equal to 'e' raised to the power of 'na'.The second relationship expresses that the logarithm of 1 to the base 'a' is equal to 'x'.

The first relationship, a² = ena, connects the exponential and power functions. It states that for any positive value of 'a', 'a' raised to the power of 2 is equal to 'e' raised to the power of 'na'. This relationship allows us to relate the exponential function, with base 'e', and the power function, where the base 'a' is raised to a fixed exponent.

The second relationship, log_a¹ = x, relates the logarithmic function to the variable 'x'. It states that the logarithm of 1 to the base 'a' is equal to 'x'. This relationship demonstrates the inverse nature of the logarithmic function, where it "undoes" the exponentiation operation. By taking the logarithm of 1 to the base 'a', we find the exponent 'x' that, when 'a' is raised to that exponent, yields 1.

The equation that can be used to determine the cost of one drink is 29.18 = 22 + 2x - 5 where the cost of each drink is $6.9

= $22

29.18 = 22 + 2x - 5

29.18 = 17 + 2x

29.18 - 17 = 2x

12.18 = 2x

x = 12.18 / 2

x = 6.9

Therefore, the equation that can be used to determine the cost of one drink is 29.18 = 22 + 2x - 5 where the cost of each drink is $6.9

There are 30 ways to seat six people around a circular table where two seatings are considered the same when everyone has the same two neighbors without regard to whether they are right or left neighbors.

To solve this problem, we need to use the formula for circular permutations, which is (n-1)! where n is the number of objects to be arranged in a circle. In this case, there are 6 people to be seated around a circular table, so the formula becomes (6-1)! = 5!.

However, we need to adjust this formula to account for the fact that two seatings are considered the same when everyone has the same two neighbors, regardless of whether they are right or left neighbors. To do this, we divide the result of the circular permutation by 2, since each seating has two possible orientations.

So the final answer is (5!)/2 = 60/2 = 30. There are 30 ways to seat six people around a circular table where two seatings are considered the same when everyone has the same two neighbors without regard to whether they are right or left neighbors.

The solution to the problem is the simplified expression: 5x³ - x² - 3x + 13.

To solve the given problem, you need to simplify and combine like terms. Start by adding the coefficients of the same degree terms.

(3x³ - x² + 4) + (2x³ - 3x + 9)

Combine the like terms:

(3x³ + 2x³) + (-x²) + (-3x) + (4 + 9)

Simplify further:

5x³ - x² - 3x + 13

In this expression, the highest power of x is ³, and the corresponding coefficient is 5. The term -x² represents the square term, -3x represents the linear term, and 13 is the constant term. The simplified expression does not have any like terms left to combine, so this is the final solution.

For the first problem, we can interpret the confidence interval as follows:

We are 95% confident that the true mean commuting time for workers who drive to work is between 27.74 and 30.06 minutes.

This means that if we were to repeat the sampling process many times and construct a 95% confidence interval each time, about 95% of those intervals would contain the true mean commuting time.

For the second problem, we can use the following formula to find a 95% confidence interval for the true mean length of long distance telephone calls:

\(CI = X ± t*(s/sqrt(n))\)

Where X is the sample mean, s is the sample standard deviation, n is the sample size, and t is the t-value from the t-distribution with n-1 degrees of freedom for a 95% confidence interval.

Plugging in the values given, we get:

\(CI = 1.68 ± t*(5.2/sqrt(45))\)

To find the value of t, we can look it up in a t-distribution table or use a calculator. For a 95% confidence interval with 44 degrees of freedom, we get t = 2.015.

Plugging this value in, we get:

\(CI = 1.68 ± 2.015*(5.2/sqrt(45)) = (0.86, 2.50)\)

So we can interpret the interval as follows:

We are 95% confident that the true mean length of long distance telephone calls made by customers of this company is between 0.86 and 2.50 minutes longer or shorter than the sample mean of 1.68 minutes.

The correct solution to the given boundary value problem (D^2 + 4^2)y = 0, with y(0) = 0 and y(phi/8) = 1, is d) y = sin 4x.

This can be found by using the value problem characteristic equation of the differential equation, which is r^2 + 16 = 0. Solving for r, we get r = +/- 4i. Therefore, the general solution is y(x) = c1 sin 4x + c2 cos 4x.

To find the values of c1 and c2, we use the boundary conditions. First, we have y(0) = 0, which gives c2 = 0. Then, we have y(phi/8) = 1, which gives c1 = 1/4. Thus, the final solution is y(x) = (1/4) sin 4x.
