When flying at an altitude of 5 miles, the lines of sight to the horizon looking north and south make about a 173.7 degree angle. how much of the longitude line directly under the plane is visible from 5 miles high?
Final answer:
The visible portion of the longitude line under the plane from an altitude of 5 miles is approximately 320.38 kilometers, using the formula D = 112.88 km √h where h is the altitude in kilometers.
Explanation:
The question asks how much of the longitude line directly under the plane is visible from an altitude of 5 miles high. To find this distance, we can use the formula given for horizon distance: D = 112.88 km √h, where h is the altitude in kilometers. Since 5 miles is approximately 8.05 kilometers, we can calculate the distance to the horizon by taking the square root of the altitude and multiplying by 112.88 kilometers.
First, calculate the square root of the altitude:
√8.05 ≈ 2.838.
Then, we multiply by the constant:
D ≈ 112.88 km × 2.838 ≈ 320.38 km.
Therefore, from an altitude of 5 miles, the visible portion of the longitude line directly under the plane is approximately 320.38 kilometers long.
The sum of three numbers is 12. The sum of twice the first number, 5 times the second number, and 6 times the third number is 59. The difference between 8 times the first number and the second number is 23. Find the three numbers.
The question requires solving a system of linear equations which results from given conditions on three unknown numbers. The unknowns can be represented by the letters x, y, and z which need to be solved for by leveraging the knowledge of algebra.
Explanation:The question given is a classic example of a system of linear equations. Let's represent the first number as x, the second number as y, and the third number as z. From the question, we have the following equations:
[tex]x + y + z = 12 \\2x + 5y + 6z = 59 \\8x - y = 23[/tex]
Solving this system, we can find the values for x, y, and z which represent the three numbers. One of the methods for solving such a system is substitution or elimination method. Nevertheless, the solving such system requires a strong understanding of basic algebra including addition, subtraction, multiplication, and division of numbers and algebraic expressions.

Find the slope of the line.
Answer:
The slope of the line is [tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
To know the slope of a line we can have the equation or to know points of the line. In this case from the graph we can get to points (-4,-1) and (0,-3). Having this and using the equation to calculate the slope, we have:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Defining:
[tex](x1=-4,y1=-1)[/tex] and [tex](x2=0,y2=-3)[/tex]
Replacing this values in the initial equation, this is:
[tex]m=\frac{-3-(-1)}{0-(-4)}[/tex]
[tex]m=\frac{-2}{4} =-\frac{1}{2}[/tex]
The slope of the line is [tex]-\frac{1}{2}[/tex]

a weightlifter uses 45 pound plates and 10 pound plates to lift 260 pounds .let x represent the number of 45 pounf weights and y represents the number of 10 pound weights .
part 1 Rights an equation is standard form that represents the situation.
part 2. if the weightlifter uses eight 10 pound weights, how many 45 pound weights did he use???????
A standard form equation representing the weightlifting situation is 45x + 10y = 260. If eight 10-pound plates are used, the number of 45-pound plates used is 4.
Explanation:The situation given can be translated mathematically to an equation in standard form as follows: 45x + 10y = 260. This equation signifies that the total weight lifted (260 pounds) is equal to the sum of the weight of the 45
pound plates
(which each weighs 45 pounds multiplied by the number of plates, represented by x) and the 10 pound plates (which each weighs 10 pounds multiplied by the number of plates, represented by y). In the second part of the question, we're told that the weightlifter uses eight 10-pound weights, so y=8. Substituting y=8 into the equation from above, it simplifies to 45x + 80 = 260, which solves to x = 4. So, if the weightlifter uses eight 10 pound plates, then he uses four 45 pound plates.

1A. Nan and Soto are designing a coffee table using four inch tiles Nan uses 30 tiles and soto uses half as many how many total tiles did they use
1B. If the area of the table is 36 inches by 24 inches will they have enough towels to cover the table if not how many more will they need
2 different questions
But they are related
Nan and Soto used a total of 45 tiles. However, to cover a coffee table that has an area of 36 inches by 24 inches, they need 54 tiles, so they will need to acquire 9 more tiles.
1A. Nan uses 30 tiles and Soto uses half as many, which means Soto uses 15 tiles. So, they used a total of 45 tiles (30 + 15).1B. The area of the coffee table is 36 inches by 24 inches, which equals 864 square inches (36 x 24). Each tile is a four-inch square, so it covers an area of 16 square inches (4 x 4).
To find out how many tiles are needed, we divide the total area of the table by the area of one tile: 864/16 = 54 tiles. Since Nan and Soto have only 45 tiles, they need an additional 54 - 45 = 9 more tiles to cover the table.
