A 38 1/25m tower is built on the summit of a mountain that is 784 1/5m above sea level.Then a lighting rod that is 3 4/5m high is built on tp of the tower. How high above sea level is the very top of the lighting rod?
I need the answer today before 4:00, No Files please Thank you.
Answers
The top of the lighting rod is \(823\frac 1{25}\) meters above the sea level.
The height of the tower is given as:
\(h_1 = 38\frac 1{25}m\)
The height of the mountain is given as:
\(h_2 = 784\frac 1{5}m\)
The height of the lighting rod is given as:
\(h_3 = \frac 4{5}m\)
The height of the lighting rod relative to the sea level is the sum of the given heights.
So, we have:
\(h =h_1 + h_2 + h_3\)
This gives
\(h =38\frac 1{25} + 784\frac 15 +\frac 45\)
Express as decimals
\(h =38.04 + 784.2 +0.8\)
\(h =823.04\)
Express as fraction
\(h =823\frac 1{25}\)
Hence, the top of the lighting rod is \(823\frac 1{25}\) meters above the sea level.

Answers
In the triangle, the measure of the exterior angle is 117°.
What is a triangle's definition?
A triangle is a basic two-dimensional geometric shape that consists of three straight sides and three angles. It is a polygon with three sides and three vertices.
The sides of a triangle are usually labeled as a, b, and c, and the angles opposite to these sides are labeled as A, B, and C respectively. The sum of the interior angles of a triangle is always 180 degrees, and each angle in a triangle is less than 180 degrees.
Now,
In a triangle, the sum of the angles = 180°.
Let's denote the three interior angles of the triangle as A, B, and C.
Then we know that:
A + B + C = 180°
We're given two of the interior angles:
B = 75° (remote interior angle)
C = 42° (remote interior angle)
To find the measure of the exterior angle, let's first find the third interior angle:
A + B + C = 180°
A + 75 + 42 = 180°
A + 117 = 180
A = 63°
Now we can use the fact that the exterior angle is equal to the sum of the two remote interior angles:
Exterior angle = B + C
Exterior angle = 75 + 42
Exterior angle = 117°
Therefore, the measure of the exterior angle of the triangle is 117°.

Find the mean, median, and mode of the contributions.
Answers
What is mean: A mean is the simple mathematical average of a set of two or more numbers. To solve for it add all numbers together then divide by how many numbers are there. (Its best to put them in order)
$40 + $40 $60 + $80 + $100= $320/5= $64 is the mean
what is median: The median is the value separating the higher half of a data sample
40,40,60,80,100 (i like to cross it out so 40 and 100 cancle each other, another 40 and 80 cancel each other) now that you are left with only 1 number which is 60 that is the median.

Bryant Industries uses forecasting to estimate the number of orders that will be placed by their customers. The table below gives the sales figures for the last four months.Month2345Sales92491942004There are different forecasting techniques used by companies like Bryant Industries to predict future sales.
One of the most widely used methods is the time-series method. This method is particularly useful when the demand for a product or service changes over time and when there are no external factors that affect the sales. In this case, we can use a time-series method called the moving average to estimate future sales. The moving average is a time-series method that uses the average of past sales data to estimate future sales. It is particularly useful when there are no external factors that affect the sales. In this case, we can use a 3-month moving average to estimate future sales. The 3-month moving average is calculated as follows: (924 + 919 + 420) / 3 = 754.33. This means that we can expect sales of around 754 units next month. The moving average method is easy to use and is a good way to get a quick estimate of future sales. However, it has some limitations. For example, it does not take into account external factors that may affect sales, such as changes in the economy or in consumer behavior.
In conclusion, Bryant Industries can use the moving average method to estimate future sales. However, they should also consider other factors that may affect sales, such as changes in the economy or in consumer behavior. By doing so, they can make more accurate forecasts and improve their overall performance.

A bag contains 99 marbles, some white and some red. The ratio of white marbles to red ones is 5:4. how many white marbles are there?
Answers
Answer:
55 white
Step-by-step explanation:
So ratio 5:4 is essentially saying, for each 5 white marbles, there are 4 red ones. This can be represented in the equation: 5x+4x=99. We specifically want an integer solution. Because what is 1.2 of a marble? And what is -1 marbles? So as x increases by 1, the entire thing increases by 9. This gives you the equation: 9x=99 which gives you x=11. So there are 55 white and 44 red.

Answers
Answer:
138° (nearest degree)
Step-by-step explanation:
Bearing: The angle (in degrees) measured clockwise from north.
The given scenario can be modelled as a right triangle (see attachment).
Therefore, the bearing is 90° + θ (shown in green on the attached diagram).
To find angle θ, use the cosine trigonometric ratio:
\(\implies \cos{\theta}=\dfrac{A}{H}\)
\(\implies \cos{\theta}=\dfrac{624}{927}\)
\(\implies \theta=\cos^{-1}\left(\dfrac{624}{927}\right)\)
\(\implies \theta=47.69018863...\)
\(\implies \theta=48^{\circ}\; \; \sf (nearest\;degree)\)
Therefore, the bearing of the drawbridge from the tower is:
\(\begin{aligned}\implies \sf Bearing&=90^{\circ}+\theta\\&=90^{\circ}+48^{\circ}\\&=138^{\circ} \end{aligned}\)

if $x$ and $y$ are positive integers such that $5x+3y=100$, what is the greatest possible value of $xy$?
Answers
The greatest possible value of $xy$ is $17\times5=\boxed{85}$. To get the greatest possible value of $xy$, we need to maximize the values of $x$ and $y$. We can start by rearranging the equation $5x+3y=100$ to solve for one of the variables in terms of the other:
$5x+3y=100 \implies 5x=100-3y \implies x=\frac{100-3y}{5}$
Since $x$ must be a positive integer, $100-3y$ must be divisible by 5. The largest multiple of 3 less than 100 is 99, so we can try values of $y$ starting from 1 and working up to 33 (because if $y\geq34$, then $5x\leq0$, which is not positive).
When $y=1$, we get $x=\frac{100-3}{5} = 19.4$, which is not an integer.
When $y=2$, we get $x=\frac{100-6}{5} = 18.8$, which is also not an integer.
When $y=3$, we get $x=\frac{100-9}{5} = 18.2$, still not an integer.
When $y=4$, we get $x=\frac{100-12}{5} = 17.6$, still not an integer.
When $y=5$, we get $x=\frac{100-15}{5} = 17$, which is an integer.
From here, we can continue to increase $y$ and see that the values of $x$ will only decrease. Thus, the greatest possible value of $x$ is 17 and the corresponding value of $y$ is 5.

The relationship between the actual air temperature (in degrees Fahrenheit) and the temperature y adjusted for wind chill (in degrees Fahrenheit, given a 30 mph wind) is given by the following
formula:
V = -26 + 1.3x
2.1 Estimate the actual temperature if the temperature
adjusted for wind chill is -35 degrees Fahrenheit.
Answers
The estimated actual temperature, when the temperature adjusted for wind chill is -35 degrees Fahrenheit, is approximately -6.923 degrees Fahrenheit.
To estimate the actual temperature if the temperature adjusted for wind chill is -35 degrees Fahrenheit, we can use the given formula:
V = -26 + 1.3x, where V represents the temperature adjusted for wind chill and x represents the actual temperature.
We are given that the temperature adjusted for wind chill is -35 degrees Fahrenheit.
Let's substitute this value into the formula and solve for x:
-35 = -26 + 1.3x
To isolate x, we can subtract -26 from both sides of the equation:
-35 + 26 = 1.3x
Simplifying the left side of the equation:
-9 = 1.3x
Now, divide both sides of the equation by 1.3:
-9/1.3 = x
Calculating the value:
x ≈ -6.923

Answers
By substituting the given values into the function and simplifying, we obtained the simplified expression (7h) / [2(-2+h)].
To simplify the given difference quotient, let's start by evaluating g(-3+h) and g(-3).
Given: g(x) = 7/(x+1)
Evaluating g(-3+h):
Replace x with (-3+h) in the function g(x):
g(-3+h) = 7/((-3+h)+1)
= 7/(-2+h)
Evaluating g(-3):
Replace x with -3 in the function g(x):
g(-3) = 7/(-3+1)
= 7/(-2)
= -7/2
Now, substitute these values into the difference quotient and simplify:
[g(-3+h) - g(-3)] / h
= [7/(-2+h) - (-7/2)] / h
= [7/(-2+h) + 7/2] / h
To simplify the expression further, we can find a common denominator for the two fractions in the numerator:
= [7(2) + 7(-2+h)] / [2(-2+h)]
= [14 - 14 + 7h] / [2(-2+h)]
= (7h) / [2(-2+h)]
Therefore, the simplified difference quotient is (7h) / [2(-2+h)].

Answers
The correct answer is (a) (x-7)^2 / 25 + (y+2)^2 / 9 = 1.
The standard equation of an ellipse is (x-h)^2 / a^2 + (y-k)^2 / b^2 = 1, where (h,k) is the center of the ellipse, a is the distance from the center to the vertices, and b is the distance from the center to the covertices.
In this case, the center of the ellipse is the midpoint of the vertices and covertices, which is (7, -2). The distance from the center to the vertices is 5 (12-7) and the distance from the center to the covertices is 3 (1-(-2)).
Therefore, the standard equation of the ellipse is (x-7)^2 / 25 + (y+2)^2 / 9 = 1, which corresponds to answer choice (a).
So the correct answer is (a) (x-7)^2 / 25 + (y+2)^2 / 9 = 1.

Answers
The number formed by the digits 16, 06, and 68 is 160668, which is determined by concatenating them in the given order.
To determine the number formed by the given digits, we concatenate them in the given order. Starting with the first digit, we have 16. The next digit is 06, and finally, we have 68. By combining these three digits in order, we get the number 160668.
When concatenating the digits, the position of each digit is crucial. The placement of the digits determines the resulting number. In this case, the digits are arranged as 16, 06, and 68, and when they are concatenated, we obtain the number 160668. It's important to note that the leading zero in the digit 06 does not affect the value of the resulting number. When combining the digits, the leading zero is preserved as part of the number.
Therefore, the number formed by the digits 16, 06, and 68 is 160668.
