At a water elevation of 6,391 ft, Mono Lake has a volume of 2,939,000 ac-ft, and a surface area of 48,100 ac. Annual inputs to the lake include 8 in of direct precipitation, runoff from gauged streams of 150,000 ac-ft per year, and ungauged runoff and groundwater inflow of 37,000 ac-ft per year. Evaporation is 45 in per year.
Required:
a. Make a water budget showing inputs, in ac-ftper year and outputs in ac-ft per year. Does the input balance the output?
b. Will the average lake level rise or fall from the 6391ft elevation over the long-term?
c. What would be the lake surface area when the inputs blance the outputs? ( Assume that the volume of gauged and ungauged runoff and ground-water inflows remain constant with a change in lake surface area).
d. What is the residence time for water in Mono Lake when the water surface is at 6391ft?

Find the coordinates for point R that proves figure TRAP is an isosceles trapezoid.
Answers
Answer:b
Step-by-step explanation: I got it right on my test
The coordinates for point R that proves figure TRAP is an isosceles trapezoid is (c - a, b)
From the diagram, we have the following highlights
There are two parallel sides in the trapezoidThe parallel sides of the trapezoid are horizontal linesThis means that the y-coordinate of point R is the same as the y-coordinate of point T.
Given that the y-coordinate of point T is b, the y-coordinate of point R can be represented as:
[tex]R =(x,b)[/tex]
For the shape to be an isosceles trapezoid, then the following must be true
[tex]x = c - a[/tex]
So, we have:
[tex]R =(c - a,b)[/tex]
Hence, the coordinates of R is (c - a, b)

29) x=8
30) x=18
Step-by-step explanation:
The picture tells you that ∠AOB and ∠COD are equal. So,
29: m∠AOB = m∠COD
Substitute.
4x - 2 = 2x + 14
Solve.
2x = 16
x = 8°
30. again, m∠AOB = m∠COD = 28
m∠AOD = m∠AOB + m∠BOC + m∠COD
Substitute.
6x = 28 + 3x -2
Simplify.
6x = 3x + 54
Solve.
3x = 54
x = 18

Let [tex]U_{n} = (-1)^{n} \frac{n^{2} }{n^{3}+3 }[/tex]
By using Leibnitz's rule
[tex]U_{n} - U_{n-1} = \frac{n^{2} }{n^{3} +3} - \frac{(n-1)^{2} }{(n-1)^{3}+3 }[/tex]
[tex]U_{n} - U_{n-1} = \frac{n^{2}(n-1)^{3} +3)-(n-1)^{2} (n^{3} +3) }{(n^{3} +3)(n-1)^{3} +3)}[/tex]

Answer:
x=21, y=17
Step-by-step explanation:
180-42= 138
2x+138=180
2x= 42
x= 21
8y+2+2x=180
8y+2 + 42=180
8y= 136
y= 17
Answer:
x=21, y=68
Step-by-step explanation:
We're given that the quadrilateral on the left is a parallelogram as indicated by the arrow markings on the sides. We're also told that the angle on the right is 42 degrees. So, we can find the bottom right angle in the parallelogram by subtracting 42 from 180, because it forms a straight angle. 180-42 is 138. By the alternate interior angles theorem, 8y+2=138, because 138 is also the angle measure of the opposite corner. we also know that the bottom left angle in the parallelogram is the same as 2x. by the alternate interior angles theorem. Notice how the sides of the parallelogram with two arrow markings are parallel, which means that the bottom left angle and the 42 degree angle are congruent, or have the same measure, because of the parallel lines. This means that 2x=42, and the bottom left angle is 42. We can solve for x and y with simple algebra now. 8y+2=138, 8y=138-2, 8y=136, y=68. 2x=42, x=42/2, x=21. So, x is 21 and y is 68.

According to the 68-95-99.7% rule, what percentage of the data from a bell-shaped distribution will be within one standard deviation of the mean
Answers
Answer:
68% of the distribution will be within one standard deviation of the mean
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
Bell-shaped = Normally distributed.
This means that 68% of the distribution will be within one standard deviation of the mean

A certain drug dosage calls for 17 mg per kg per day and is divided into two doses (1 every 12 hours). If a person weighs 255 pounds, how many milligrams of the drug should he receive every 12 hours? Round your dosage to the tenth of a milligram.
Answers
Answer:
985.15mg
Step-by-step explanation:
Calculation for how many milligrams of the drug should he receive every 12 hours
First step is to calculate the weight in kg
255 lbs = 255/2.2 = 115.9 kg
Second step is multiply mg/kg in order to get total medicine per day
Dose per day=115.9kg × 17 mg
Dose per day= 1,970.3
Third step is to calculate how many milligrams of the drug should he receive by dividing the day dose by 2
Dose milligrams=1,970.3/2
Dose milligrams=985.15mg
Therefore how many milligrams of the drug should he receive every 12 hours will be 985.15mg

2x+3= -15 what is x step by step
Answers
Answer: x = -9
Step-by-step explanation: To solve for x, we first isolate
the term containing x which in this case is 2x.
Since 3 is being added to 2x,
we subtract 3 from both sides of the equation.
On the left, the +3 and -3 cancel out
and on the right, -15 - 3 is -18.
So we have 2x = -18.
Now we can finish things off by dividing
both sides of the equation by 2.
On the left, the 2's cancel and on
the right, -18 divided by 2 is -9.
So we have x = -9 which is the solution to this equation.
