The values using Law of Sines are:
∠ B = 62∘; b = 11.58 and c = 16.40.
Explain the Law of Sines?The relationship between a triangle's sides and angles is demonstrated using the sine rule. It is specified as:
A/Sin(A) = B/Sin(B) = C/Sin(C)
Where A, B, and C are indeed the angles and A, B, and C are the angles' opposing sides.
∠ A = 43 ∘ , ∠ C = 75 ∘ , b = 15 ;
Part a:
∠ B = 180 - ∠ A - ∠ C
∠ B = 180 - 43 ∘ - 75∘
∠ B = 62∘
Part b: the value of a.
a/Sin(A) = b/Sin(B)
a = b/Sin(B) * Sin(A)
a = 15/Sin(62) * Sin(43)
b = 11.58
Part c: the value of c
b/Sin(B) = c/Sin(C)
c = b/Sin(B) * Sin(C)
c = 15/Sin(62) * Sin(75)
c = 16.40
Thus, the values using Law of Sines are obtained.

24687abc is divisible by 125. what is the sum of the digits of all possible values of ‘a’?
To find the sum of the digits of all possible values of 'a', we need to add the sum of the digits of each value of abc. The sum of the digits for all possible values of a would be 8 + 7 + 15 + ... + 27, which can be calculated further.
The divisibility rule for 125 states that a number is divisible by 125 if the last three digits are divisible by 125. In the case of 24687abc, we know that the last three digits (abc) must be divisible by 125. This means that abc must be a multiple of 125. The smallest multiple of 125 is 125, and the largest is 999, so the possible values of abc are 125, 250, 375, 500, ..., 999.
The sum of the digits of each possible value of a can be calculated by adding the individual digits of each value of abc. For example, for the value 125, the sum of the digits is 1 + 2 + 5 = 8. For the value 250, the sum of the digits is 2 + 5 + 0 = 7. For the value 375, the sum of the digits is 3 + 7 + 5 = 15.

3-4-5 Triangles in Real Life
Carpentry frequently employs 3-4-5 triangles to verify that angles are 90°
What is the 3-4-5 triangle rule?
The 3-4-5 triangle rule states that you must multiply 3, 4, and 5 by the same amount in order to accomplish this.
The theorem demonstrates the effectiveness of the 3-4-5 approach and the fact that multiplying the 3-4-5 triangle, as opposed to using the formula to determine the length, will yield the missing side.
A ratio can be conceived of as the lengths 3, 4, and 5. To obtain triangles with varying lengths but the same proportion, this ratio can be scaled.
A real life example of the 3-4-5 triangle rule is carpentry, where it is frequently employed to verify that angles are 90°.

The is ________ the horizontal center line on the coordinate plane (left to right). The _________ is the vertical center line on the coordinate plane. The point where the x and y axis interact, identified by 0 is called the _________
The x-axis is the horizontal center line on the coordinate plane (left to right). The y-axis is the vertical center line on the coordinate plane. The point where the x and y axis interact, identified by 0, is called the origin.
This point is located at coordinates (0,0). The x-axis is usually associated with the horizontal axis in a two-dimensional graph and is typically used to represent different categories of data. The y-axis is associated with the vertical axis and is used to represent a range of values from high to low.
The formula for determining the coordinates of a point is (x,y). The x-coordinate is the distance from the origin on the x-axis and the y-coordinate is the distance from the origin on the y-axis. For example, if a point has an x-coordinate of 4 and a y-coordinate of -3, the coordinates of the point would be (4,-3). To calculate the distance between two points, you can use the distance formula, which is the square root of the sum of the squares of the differences between the x-coordinates and the y-coordinates. For example, if the coordinates of point A are (2,3) and the coordinates+ of point B are (7,1), the distance between A and B would be calculated by taking the square root of (5-2)^2+(1-3)^2, which would equal 5.

Andre and Elena are each saving money. Andre starts with $100 in his savings account and adds $5 per week. Elena starts with $10 in her savings account and adds $20 each week.
After four weeks, who has more money in their savings account? Explain how you know.
After how many weeks will Andre and Elena have the same amount of money in their savings accounts?
Answer:
Andre has more money in his savings account.
Step-by-step explanation:
We need to have equations for both Andre and Elena. Andre starts with $100 in his savings and adds $5 per week. Based on this, Andre's equation will be y = 5x + 100. Elena starts with $10 and adds $20 per week. Based on this, Elena's equation will be y = 20x + 10.
Andre: y = 5x + 100
Elena: y = 20x + 10
We have to figure out who will have more money in their account after 4 weeks. To do that, we plug in 4 into x because x is the number of weeks.
Andre: y = 5(4) + 100
y = 20 + 100
y = 120
Andre has $120 after 4 weeks.
Elena: y = 20(4) + 10
y = 80 + 10
y = 90
Elena has $90 after 4 weeks.
Which is greater? $120 or $90? That's right, its $120. Andre has more money in his savings account. I hope this helps!

The perimeter of the rectangle is P = 27n + 1.
What is perimeter?The whole distance encircling a shape is referred to as its perimeter. It is the length of any two-dimensional geometric shape's boundary or outline. Depending on the size, the perimeter of several figures can be the same. Consider a triangle built of an L-length wire, for instance. If all the sides are the same length, the same wire can be used to create a square.
The length of the rectangle is: l = 9.5n+10.
The width of the rectangle is: w = 4n-9.5.
The perimeter of the rectangle is given as:
P = 2(l + w)
P = 2(9.5n + 10 + 4n-9.5)

The equation of the line that passes through (-2,1) and is perpendicular to y = -5x² is y = -10x + 21
The equation of a line is a mathematical representation of the relationship between its x and y values.
In this case, we are given a line that passes through the point (-2,1) and is perpendicular to y = -5x².
To find the equation of this line, we first need to find the slope of the line that is perpendicular to y = -5x².
The slope of a line can be found by finding the derivative of the original equation.
In this case, the derivative of
=> y = -5x² is -10x,
which gives us the slope of -10x.
Since we know that the line passing through (-2,1) is perpendicular to
y = -5x²,
we can use the point-slope form of the equation of a line.
The point-slope form of the equation is given by
=> y - y1 = m(x - x1),
where m is the slope and (x1, y1) is a point on the line.
Plugging in the values, we have
=> y - 1 = -10(x + 2).
We can simplify this equation further by distributing the -10 and combining like terms.

A software company provides specialized resort reservation software that can be tailored to the needs of its customers. The company’s 120 customers pay yearly subscription costs that can vary from customer to customer. The company knows that to be profitable, it needs each customer to be spending at least $23,000 per year, on average. The company selects a random sample of 33 customers and computes a mean of $27,871 and a standard deviation of $309. 10. It performs a hypothesis test and computes a very small p-value. The software company concludes that the mean is greater than $23,000. Was it appropriate for the software company to perform the hypothesis test and make the conclusion that was made?
This hypothesis test can be set up as a one-tailed test, where the null hypothesis is that the mean is equal to $23,000 and the alternative hypothesis is that the mean is greater than $23,000.
The p-value, which is the probability of obtaining a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true, can then be used to determine whether to reject or fail to reject the null hypothesis.
In this case, if the p-value is very small, it indicates strong evidence against the null hypothesis and in favor of the alternative hypothesis.
This means that it is highly unlikely that the mean subscription cost per customer is equal to $23,000, given the sample data and the assumptions of the test.
Therefore, it is appropriate for the software company to make the conclusion that the mean is greater than $23,000. However, it is important to note that the conclusion should be based on the assumptions of the test being met and the sample being representative of the population of customers.
Additionally, it is always good practice to report the results of the test, including the p-value, the sample mean, the sample standard deviation, and the sample size, to provide context for the conclusion.

Suppose we use a fair die with an infinite number of sides, where each face corresponds to a different natural number, and roll the die to determine the randomly selected number. Here, each natural number has an equal probability of being chosen.
Alternatively, we could use a pseudorandom number generator to generate a sequence of numbers that appear to be randomly distributed and choose one of the numbers in the sequence as the randomly selected natural number. In this case, while the process of generating the numbers is deterministic, the numbers themselves appear to be randomly chosen and each natural number has an equal probability of being chosen.
It is also possible for every number to have a positive (nonzero) probability of being chosen, as long as the probabilities are defined in such a way that they sum up to 1. This can be achieved by using a uniform distribution where each natural number has a positive but nonzero probability of being chosen.

A first number plus twice a second number is 10. Twice the first number plus the second totals 14. Find the numbers
Answer:
Below
Step-by-step explanation:
x + 2y = 10 given
2x + y = 14 given multiply this equation by -2 to get :
-4x - 2y = - 28 add to top equation to get
-3x = -18 so x = 6
x + 2y = 10 so y = 2

Comparison of Manueala's relative number points:
1 1/2 > - 4 1/2
Manueala scored more points against the China Dragons than against Canada Moose .
The correct answer is A.
What is an inequality?Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given,
Manueala scores relative to average against China Dragons
= -4 1/2 points
Manueala scores relative to average against Canada Moose
= 1 1/2 points
If Manueala scored x points,
season average against China Dragons is y.
season average against Canada Moose = z
x - y = -4 1/2
x - z = 1 1/2
∵ 1 1/2 > - 4 1/2
∴ x - z > x - y
- z > -y
⇒ z < y
Hence,
Relative scores to both seasons can be written as inequality
1 1/2 > - 4 1/2
Season average against China Dragons is more than season average against Canada Moose.

Yessica leaves her house on her bicycle to locate a geocache at the same time Zoe leaves her house heading for the same cache. Zoe lives further away than Yessica so she takes her car and travels 12 mph faster than Yessica. Their combined distance traveled is 63 miles. If both women arrive at the geocache site after 90 minutes, find their average speeds
Yessica and Zoe's average speeds are equal to 63 miles/90 minutes, or 0.7 miles/minute.
To solve this problem, we need to use the formula for average speed, which is distance divided by time. We are given the combined distance traveled by both women, which is 63 miles, and the total time they took, which is 90 minutes. We can divide the distance (63 miles) by the time (90 minutes) to get the average speed: 63/90 = 0.7. This means that their average speed was 0.7 miles per minute. This can also be expressed as 42 mph, which is the same as 0.7 miles per minute. To summarize, Yessica and Zoe's average speeds were 0.7 miles per minute or 42 mph.
