Construct triange ABC, in which AB = 6 cm, angle BAC = 96 degrees and angle ABC = 35 degrees. Measure the length of BC. Give your answer to 1 d. P
From the construction of the triangle ABC we get that the measure length of BC is approximately 4.22cm
To construct triangle ABC, we can follow these steps:
Draw a line segment AB of length 6 cm.Draw an angle of 96 degrees at point A using a protractor.Draw an angle of 35 degrees at point B using a protractor.The intersection point of the two lines that were drawn in step 2 and 3 will be point C, which is the third vertex of the triangle.To measure the length of BC in triangle ABC, we can use the law of sines.
The law of sines states that in any triangle ABC:
a / sin(A) = b / sin(B) = c / sin(C)
Where a, b, and c are the lengths of the sides of the triangle opposite to the angles A, B, and C, respectively.
In our triangle ABC, we know AB = 6 cm, angle BAC = 96 degrees and angle ABC = 35 degrees. We can find the measure of angle ACB by using the fact that the sum of the angles in a triangle is 180 degrees:
angle ACB = 180 - angle BAC - angle ABC
= 180 - 96 - 35 = 49 degrees
Now, we can apply the law of sines to find the length of BC:
BC / sin(35) = 6 / sin(96)
BC = 6 × sin(35) / sin(96)
Using a calculator, we can evaluate this expression to get:
BC ≈ 4.22 cm
Therefore, the length of BC in triangle ABC is approximately 4.22 cm.

How is the quotient of 556 and 16 determined using an area model?
Enter your answers in the boxes to complete the equations. Your final answer should be a mixed number in simplest form.
Answer:
To use an area model to determine the quotient of 556 and 16, we can divide a rectangle of area 556 into 16 equal parts. Each part will have an area of 556/16.
We can start by dividing 556 into 16 groups of 10 (160), and then into 16 groups of 3 (48). That leaves us with a remainder of 4.
So we have:
556 = 16 x 34 + 48 + 4
This shows that 556 can be written as 16 times some whole number (34) plus a remainder of 48 + 4/16.
Simplifying the remainder, we have:
48 + 4/16 = 48 + 1/4 = 48.25
Therefore, the quotient of 556 and 16 is:
556/16 = 34 1/4
The quotient of 556 and 16 using an area model can be determined by producing a rectangle with the total area of 556 and one side of 16. The length of the other side will be the quotient. In this case, the quotient is 34 3/4.
Explanation:When asked to determine the quotient of 556 and 16 using the area model, one way to think of this is making a rectangle. The total area is 556 and one side is 16. The length of the other side will be the quotient.
Start by first estimating how many times 16 could fit into 556. Let's take 30 as an estimate, because 30*16 = 480, which is relatively close to 556. Draw a rectangle with the width of 16 and the length of 30.
Find the difference between the rectangle's area and 556. So, 556 - 480 = 76. Now, 76 is our remaining area to fill. 16 goes into 76 four more times, adding up to 64.
There is still a leftover area, which is 76-64 = 12. This is smaller than our width of 16. So, your final answer is 34 12/16 or 34 3/4 in simplest form.

Which equations arise when the steps of the Euclidean algorithm are reversed to express the greatest common divisor of each of these pairs of integers as a linear combination of these integers? (123, 2347) (Check all that apply.) Check All That Apply 1 = 10 - 3.3 1 = 37.10 - 3. 123 1 = 37.2347-706 - 123 1 = 37.10 -9.41 d d 1 = 36.2347-583 123
The equations that arise when the steps of the Euclidean algorithm are reversed to express the greatest common divisor of each of these pairs of integers as a linear combination of these integers are:
1 = 10 - 3.3, 1 = 37.10 - 3.123, and 1 = 37.2347-706 - 123.
What is the Euclidean algorithm?The Euclidean algorithm is a recursive method for finding the greatest common divisor (GCD) of two positive integers. When we divide the larger number by the smaller number, we obtain the remainder. The smaller number and the remainder are then passed on as input to the next round. The process continues until the remainder is zero, at which point the GCD is obtained.
The solution to the given problem is as follows:
We will use the Euclidean algorithm to compute gcd(123, 2347).
123 ÷ 2347 = 0 remainder 123.2347 ÷ 123 = 19 remainder 106.123 ÷ 106 = 1 remainder 17.106 ÷ 17 = 6 remainder 4.17 ÷ 4 = 4 remainder 1.4 ÷ 1 = 4 remainder 0.The last nonzero remainder we get is 1.
Therefore, the greatest common divisor (GCD)(123, 2347) = 1.
The greatest common divisor of 123 and 2347 can be expressed as a linear combination of the two numbers in the following ways:1 = 10 - 3.3, 1 = 37.10 - 3.123, and 1 = 37.2347-706 - 123.
Thus, the equations arising when the steps of the Euclidean algorithm are reversed to express the greatest common divisor of each of these pairs of integers as a linear combination of these integers are:

If the sum of three consecutive natural numbers is 30 , find the numbers. Let us first form the equation. If y is the smallest among the three consecutive natural numbers, then the second smallest would be y+$ and the largest would be .
Answer: 9, 10, and 11
Step-by-step explanation:
If the sum of three consecutive natural numbers is 30, then we can represent the smallest of the three numbers as x. The next two consecutive natural numbers would be x+1 and x+2. Therefore, we can form the equation:
x + (x+1) + (x+2) = 30
Simplifying the left-hand side, we get:
3x + 3 = 30
Subtracting 3 from both sides, we get:
3x = 27
Dividing by 3, we get:
x = 9
Therefore, the three consecutive natural numbers are 9, 10, and 11.

Answer:
35 passengers produce the maximum revenue for the bus company.
Step-by-step explanation:
Define the variables:
Let "x" be the total number of passengers.Let "y" be the total revenue of the bus company (in dollars).If there are 30 or fewer passengers, each passenger will be charged $80. Therefore, the equation for the total revenue for 30 or fewer passengers is:
[tex]y = 80x,\quad x \leq 30[/tex]
If there are more than 30 passengers, each passenger will be charged $80 minus $2 for every passenger over 30. Therefore, the equation for the total revenue for more than 30 passengers is:
[tex]y = [80 - 2(x - 30)]x, \quad x > 30[/tex]
This simplifies to:
[tex]y = [80 - 2x + 60]x, \quad x > 30[/tex]
[tex]y = [140 - 2x]x, \quad x > 30[/tex]
[tex]y = 140x - 2x^2, \quad x > 30[/tex]
To maximize revenue, we need to find the value of x that maximizes the above equation.
Since this is a quadratic function, the maximum value occurs at the vertex of the parabola.
The x-value of the vertex of a parabola in the form y = ax² + bx + c is when x = - b/2a. Therefore, the x-value of the vertex is:
[tex]\implies x_{\sf vertex}=\dfrac{-140}{2(-2)}=\dfrac{-140}{-4}=35[/tex]
Therefore, the number of passengers that produce the maximum revenue for the bus company is 35.

Kaitlin is on vacation at a tropical bay that has three islands. She rents a boat on Island A and plans to navigate to Island C, which is 13 miles away. Based on the figure below, at what angle should she navigate to go to Island C?
She should navigate at angle 76.86° to go to Island C.
How to find the angle for navigation?The cosine rule is for solving triangles which are not right-angled in which two sides and the included angle are given. The following are cosine rule formula:
cosA = (b² + c² - a²)/2bc
where a, b and c are the lengths and A, B and C are the angles for the islands respectively
Using the formula:
cosA = (b² + c² - a²)/2bc
cosA = (13² + 11² - 15²)/(2*13*11)
cosA = 5/22
A = arc cos(5/22)
A = 76.86°
Thus, θ = 76.86

A survey was given to a random sample of 1050 voters in the United States to ask about their preference for a presidential candidate. Of those surveyed, 693 respondents said that they preferred Candidate A. Determine a 95% confidence interval for the proportion of people who prefer Candidate A, rounding values to the nearest thousandth
As per the confidence interval, the true proportion of people in the population who prefer Candidate A lies somewhere between 0.622 and 0.698, based on the results of the survey of 1050 voters.
To calculate the margin of error, we will use the following formula:
Margin of error = z x standard error
Where z is the critical value from the standard normal distribution corresponding to our desired confidence level (95%), and the standard error is given by:
Standard error = √[(sample proportion x (1 - sample proportion)) / sample size]
Using a z-table, we find that the critical value for a 95% confidence interval is 1.96
Plugging in the values we have, we get:
Standard error = √[(0.66 x 0.34) / 1050] = 0.0193
Margin of error = 1.96 x 0.0193 = 0.0378
Therefore, the 95% confidence interval for the proportion of people who prefer Candidate A is:
0.66 ± 0.0378
Rounded to the nearest thousandth, the lower bound of the confidence interval is 0.622 and the upper bound is 0.698.

Amir drove from Jerusalem to the lowest place on Earth, the Dead Sea.
His altitude relative to sea level (in meters) as a function of time (in minutes) is graphed.
How long did it take Amir to reach sea level?
In order to solve this problem, we need to begin by examining the graph of Amir's altitude relative to sea level. We can see that the graph starts at an altitude of 700 meters and ends at an altitude of 400 meters.
We can also see that the slope of the graph is negative, which means that the altitude is decreasing over time. This means that it will take Amir some amount of time to reach sea level (which is 0 meters).
To calculate how long it took Amir to reach sea level, we can use the following equation:
Time = (Altitude Final - Altitude Initial) / (Rate of Change)
In this equation, the Rate of Change is the slope of the graph, which can be determined by examining the graph.
Plugging in our values, we get:
Time = (400 - 700) / (-6) = 100 / (-6) = -16.67 minutes
Therefore, it took Amir 16.67 minutes to reach sea level.
