A sum of money is to be divided between Alyah, Byron and Cecil. Alyah receives $1 plus one-third of what is left. Byron then receives $6 plus one-third of what remains. Cecil receives the rest, which amounts to $40. How much did Byron receive? (A) $26 (B) $28 (C) $30 (D) $32 (E) $34
Answer:
(A) $26
Step-by-step explanation:
You want to know the amount Byron received from the distribution to Alyah, Byron, and Cecil, given Cecil received $40.
SetupLet x represent the amount being distributed, and a, b, c represent the amounts received by Alyah, Byron, and Cecil, respectively.
The given relations tell us ...
a = 1 + 1/3(x -1)
b = 6 + 1/3(x -a -6)
c = x -a -b = 40
SolutionSubstituting for b gives us ...
40 = x - a - (6 +1/3(x -a -6)) = x -a -6 -1/3x +1/3a +2 = 2/3x -2/3a -4
44 = 2/3(x -a) . . . . . . . add 4, factor out 2/3
66 = x -a . . . . . . . . . multiply by 3/2
Substituting for a gives us ...
66 = x -(1 +1/3(x -1)) = x -1 -1/3x +1/3 = 2/3x -2/3 = 2/3(x -1)
99 = x -1 . . . . . . . multiply by 3/2
100 = x . . . . . . add 1
DistributionThen ...
a = 1 + 1/3(100 -1) = 1 + 99/3 = 34
b = 6 + 1/3(100 -34 -6) = 6 + 1/3(60) = 26
Byron received $26.
__
Additional comment
Based on results, the "what is left" is the amount after the $1 or $6 distributions are made.
Alyah: $34, Byron: $26, Cecil: $40, for a total of $100.

The table shows three unique, discrete functions.
Which statements can be used to accurately compare the functions? Select two options.
g(x) has the lowest minimum.
f(x) has the greatest maximum.
All three functions have a y-intercept.
All three functions have an x-intercept.
The domain of all three functions is the s
We are aware that a discrete function is one that satisfies the criteria for a function and has a countable domain (represented as a collection of disconnected points) (each input has at most one output). Many inputs in discrete functions won't have any outputs.
According to the inquiry,
All three of the functions have a y-intercept and, given the facts in the question, f(x) is the highest maximum.
The largest maximum of the three functions—g(x), f(x), and f(y)—has an x-intercept.
Three distinct discrete functions are displayed in the table.
f(x)minimum: 1 g(x)minimum; -4 12 h(x)minimum-5; as a result, f(x)maximum: 10 g(x)maximum; 3 12 h(x)maximum; 12 f(x)domain; (0, 2) g(x)domain; (-2, 2) h(x)domain; (0, 1) g(x)y-inter (0, -5)
Using the procedures above, we may conclude that f(x) has no x.

What is the median of the number 445 767 712 and 3?
The Median for the following data 3 445 712 767 will be 578.5.
One measure of central tendency is the median. The median of a set of numbers is its midway value. It splits a sample of given data into the upper and lower halves. A minimum of half of the observations are above the median and a minimum of half are below it.
When there are exactly even numbers of observations in a data collection, the median can be calculated as follows:
sorting of the sample data in ascending or descending order.
If there are an even number of observations (let's say n), identify the (n/2)nd and [(n/2) + 1] th observations.
The average of the top two observations is the same as the median of the data given (as determined in step 2).

find the exact length of the curve. y = ln 1 − x2 , 0 ≤ x ≤ 1 9
The exact length of the curve for the function y = ln(1 - x²) is log(5/4) - 1/9
The general formula for the arc length of the curve y on the interval [a, b] is written as,
[tex]s=\int\limits^a_b {\sqrt{1+(\frac{dy}{dx})^2 } } \, dx[/tex]
Here we have given that the function is y = ln(1 - x²)
And the limit is 0 ≤ x ≤ 1/9
When we differentiate the function, then we get the value of y' as,
y' = 1/(1 - x²) × (-2x) = -2x/(1 - x²)
Now, we have to apply the values on the arc length formula, then we get,
[tex]s=\int\limits^{1/9}_0 {\sqrt{1+(\frac{-2x}{1-x^2} )^2 } } \, dx[/tex]
When we simplify this one then we get,
[tex]s=\int\limits^{1/9}_0 {\sqrt{\frac{1+x^4-2x^2+4x^2}{(1-x^2)^2} } } \, dx[/tex]
Now, we have to divide numerator by denominator and expressing using
the rule Dividend/Divisor = Quotient + (Remainder/Divisor)
Then we get the resulting equation as,
[tex]s=\int\limits^{1/9}_0 {-1 + \frac{2}{1-x^2} } \, dx[/tex]
When we apply the limit value, then we get
s = −1/9 + log∣10/8∣−log(1)
When we simplify this one then we get,

In 2010, the population of a city was 193,000. From 2010 to 2015, the population grew by 6%. From 2015 to 2020, it fell by 3%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answer:
6138
Step-by-step explanation:
First, we have to find the population of the city in 2015
6% = 0.06
193,000 times 0.06 = 11580 people increase
We know it is increasing, so we have to add them
193,000 + 11580 = 204580 people in 2015
Now let's find the 3% decrease
3% = 0.03
204580 times 0.03 = 6137.4
So, about 6138 people decrease from 2015 to 2020
A 5 1/2 inch candle burns down in 11 hours. how far has it burned after 6 1/2 hours?
The candle has burned down [tex]3 \frac{3}{4}[/tex] inches after 6.5 hours.
To calculate this, we first need to determine the rate at which the candle burns by dividing the total burn time (11 hours) by the total length of the candle ( [tex]5 \frac{1}{2}[/tex] inches). This gives us a burn rate of 2 hours per inch.
Next, we can multiply the burn rate by the time the candle has been burning (6.5 hours) to determine how far the candle has burned. This gives us a result of 13 inches, which is equal to [tex]3 \frac{3}{4}[/tex] inches in standard units. Therefore, the candle has burned down [tex]3 \frac{3}{4}[/tex] inches after 6.5 hours.

How do you arrange the angles of a triangle from smallest to largest?
If you have three side lengths, you should find the angle opposite the smallest side to determine the lowest angle, the angle opposite the medium-sized side to determine the greatest angle, and the angle opposite the largest side to determine the greatest angle.
What are angles?Two rays that have a common terminal and are referred to as the angle's sides and vertices, respectively, make up an angle in Euclidean geometry. Two rays can form angles in the plane where they are positioned.
Angles are also produced when two planes intersect.
These are what are known as dihedral angles.
Consequently, if you have three side lengths, you should discover the lowest angle by finding the angle that is opposite the smallest side, the medium-sized angle by finding the angle that is opposite the medium-sized side, and the greatest angle by finding the angle that is opposite the largest side.
Therefore, if you have three side lengths, you should find the angle opposite the smallest side to determine the lowest angle, the angle opposite the medium-sized side to determine the greatest angle, and the angle opposite the largest side to determine the greatest angle.
