What is the SSS theorem?
Side-Side-Side (SSS) Theorem; Two triangles are congruent if three sides of one are equal respectively to three sides of the other (SSS=SSS).
Side-Side-Side or SSS is a kind of triangle congruence rule where it states that if all three sides of one triangle are equal to all three corresponding sides of another triangle, the two triangles are considered to be congruent. Two or more triangles are said to be congruent when the measurements of the corresponding sides and the corresponding angles are equal. Let us learn more about the SSS congruence rule, SSS theorem, the formula, and solve a few examples.
The SSS postulate applies to triangles that have the same measurements for corresponding sides. An example would be a triangle that has side lengths 3, 4, and 5 and a triangle that has side lengths 4, 3, and 5

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

1. Ryan works at a store. He is paid an hourly rate plus 17% commission for all products that he sells.
One week, he was paid $459 for working 20 hours and selling $1700 worth of products. What is his
hourly rate?
Answer:
$8.50
Step-by-step explanation:
To find Ryan's hourly rate, we need to first determine the total amount of money he made from commission. Since Ryan was paid 17% commission for all the products he sold, and he sold $1700 worth of products, he made 17/100 * $1700 = $289 in commission.
Next, we need to subtract this amount from his total pay to find the amount he was paid for working. Since Ryan was paid a total of $459, and made $289 in commission, he was paid $459 - $289 = $170 for working.
Finally, we can use this amount to calculate his hourly rate by dividing it by the number of hours he worked. Since Ryan was paid $170 for working 20 hours, his hourly rate is $170 / 20 = $8.50 per hour.
Therefore, Ryan's hourly rate is $8.50.
To find Ryan's hourly rate, we need to first calculate how much money he made from commissions. We can do this by multiplying his total sales by the commission rate: $1700 * 0.17 = $289.
Next, we need to subtract the commission from his total pay to find his base pay: $459 - $289 = $170.
Finally, we can divide his base pay by the number of hours he worked to find his hourly rate: $170 / 20 hours = $<<170/20=8.50>>8.50 per hour.
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.

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.

which of the following is not an example of a binomial distribution? a.) the probability of a dart player missing the bullseye seven times in eight attempts. b.) the probability of rolling a die eight times and getting an odd number or a prime number four times. c.) the probability of a basketball player making a free throw seven times in ten attempts. d.) the probability of flipping a coin four times and never landing on tails.
The answer is B). "the probability of rolling a die eight times and getting an odd number or a prime number four times."
A binomial distribution is a statistical distribution that describes the probability of a certain number of successful outcomes in a fixed number of independent trials. In order for a situation to be a binomial distribution, the following conditions must be met:
There must be a fixed number of trials.
Each trial must have only two possible outcomes (e.g., success or failure).
The probability of success must be the same for each trial.
The first three answer choices all involve situations that meet these conditions and are therefore examples of binomial distributions. The fourth answer choice, however, involves rolling a die, which has more than two possible outcomes (1, 2, 3, 4, 5, or 6). This means that it is not a binomial distribution.

What us the third step in sketching the graph of a rational function
The third step in sketching the graph of a rational function is "Finding the function's zeros and vertical asymptotes and plotting them on a number line".
What is vertical asymptotes?
A graph's vertical asymptote is a vertical line with the equation x = a, where the graph tends to positive or negative infinity as the inputs get closer to the value of a. A graph's horizontal asymptote is a horizontal line with the equation y = b, where the graph approaches the line as the inputs go closer to ∞ or –∞.
The steps to sketch a graph of rational function:
1. Ensure that the function's denominator and numerator are listed in decreasing order of power.
2. Discover the domain
3. Completely factor the numerator and denominator. Any shared factors between the numerator and denominator should be eliminated. (Once factors have been cancelled, the reduced function is what remains. For all subsequent actions, employ the reduced function.) Skip Step 4 if there are no common factors.

For a fundraiser, a group plans to sell granola bars and bottles of water at the same prices as described in Part A. The group wants the income from the fundraiser to be at least $150.Choose the inequality to show the number of granola bars x and the number of bottles of water y that must be sold.A. 1.4x + 0.75 y > 150B. 1.4x + 0.75y ≥ 150C. 1.4x + 0.75 < 150D. 1.4x + 0.75 ≤ 150
The group needs to sell at least 104 granola bars and any number of bottles of water in order to make a profit of at least $150.
The correct inequality is B. 1.4x + 0.75y ≥ 150. This inequality states that the group must sell at least $150 worth of items in order to make a profit. The cost of a granola bar is $1.40, and the cost of a bottle of water is $0.75. Therefore, the total cost of the items must be greater than or equal to $150. The formula for this inequality is 1.4x + 0.75y ≥ 150, where x represents the number of granola bars sold and y represents the number of bottles of water sold.
To solve this inequality, we can first multiply both sides of the inequality by 100. This will give us 140x + 75y ≥ 15000. Next, we can subtract 75y from both sides to get 140x ≥ 14250. Finally, we can divide both sides of the equation by 140 to get x ≥ 102.86. This means that the group needs to sell at least 103 granola bars in order to make a profit of at least $150. This can be further simplified by rounding up the granola bars sold to 104. Therefore, the group needs to sell at least 104 granola bars and any number of bottles of water in order to make a profit of at least $150.

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

What are actual roots of FX according to the rational root theorem The following are potential roots of FX 2x 2 2x 24 4 3 2 3 4?
All the rational roots of the polynomial f(x) = 20x4 + x3 + 8x2 + x - 12 are 3/4 and -4/5.
We have the given polynomial:
f(x) = 20x4 + x3 + 8x2 + x - 12
All potential polynomial roots are represented by rational numbers, according to the Rational Root Theorem:
x = a/b
Where a is a factor of a constant term
b is the factor of coefficient of leading term
From the given polynomial:
-12 is the constant term and 20 is the coefficient of leading term
The possible factors of -12 are ±1, ±2, ±3, ±4, ±6, ±12
The possible factors of 20 are ±1, ±2, ±4, ±5, ±10, ±20
So the rational roots = (±1, ±2, ±3, ±4, ±6, ±12)/ (±1, ±2, ±4, ±5, ±10, ±20)
Solve for x when the given function is equal to zero
20x4 + x3 + 8x2 + x - 12 = 0
(4x - 3)(5x + 4)(x2 + 1) = 0
So we get:
4x - 3 = 0 or 5x + 4 = 0 or x2 + 1 = 0
x = 3/4, x = -4/5, x =1, x = -1
Hence, the rational roots are x = 3/4, x = -4/5.

f(x) = 20x4 + x3 + 8x2 + x - 12
x = a/b
b is the factor of coefficient of leading term
-12 is the constant term and 20 is the coefficient of leading term
The possible factors of 20 are ±1, ±2, ±4, ±5, ±10, ±20
So the rational roots = (±1, ±2, ±3, ±4, ±6, ±12)/ (±1, ±2, ±4, ±5, ±10, ±20)
Solve for x when the given function is equal to zero
20x4 + x3 + 8x2 + x - 12 = 0
(4x - 3)(5x + 4)(x2 + 1) = 0
4x - 3 = 0 or 5x + 4 = 0 or x2 + 1 = 0
x = 3/4, x = -4/5, x =1, x = -1

Forty percent of the pupil in m. Alcantara' grade 6 claa are 12 year old. Another 0. 25 are 13 year old and the ret of the cla i 11 year old. Write 11 a a fraction,decimal,and percent
Answer:
7/20
0.35
35%
Step-by-step explanation:
12 year olds: 40%
12 year olds: 25%
11 year olds: 100% - 40% - 25% = 35%
35% = 35/100 = 7/20
35% = 0.35
35% = 35%

A police car notices a speeding car travelling at 60 ft/s East, 5 s after it passes the intersection. The police gives chase immediately, and they start off 650 ft South of the intersection. The police car will run with a velocity of 80 ft/s, going North.
Answer:
To find out how long it will take for the police car to catch up to the speeding car, you can use the following formula:
t = d / v
Where t is the time it takes to catch up, d is the distance between the police car and the speeding car, and v is the relative speed of the police car compared to the speeding car.
In this case, the distance between the police car and the speeding car is given by the Pythagorean theorem:
d = sqrt((650 ft)^2 + (60 ft/s * 5 s)^2) = 674.22 ft
The relative speed of the police car compared to the speeding car is given by:
v = 80 ft/s - 60 ft/s = 20 ft/s
Plugging these values into the formula, we get:
t = d / v = 674.22 ft / 20 ft/s = 33.71 s
So it will take the police car approximately 33.71 seconds to catch up to the speeding car.
Note: This is just an approximation and the actual time required may vary depending on the exact positions and speeds of the two cars
Answer: it will take the police car 25 seconds and 2000 feet to catch up with the speeding car.
Step-by-step explanation: To determine the distance and time that the police car needs to catch up with the speeding car, we can set up the following system of equations:
Let x be the time it takes for the police car to catch up with the speeding car
Let y be the distance the police car needs to travel to catch up with the speeding car
The distance the speeding car travels in x seconds is given by the equation:
60x = distance
The distance the police car travels in x seconds is given by the equation:
80x = y
The distance between the two cars at the start is given by the equation:
(y - 650)^2 + 650^2 = x^2
We can solve this system of equations by substituting the second equation into the third equation, resulting in:
(80x - 650)^2 + 650^2 = x^2
Expanding and rearranging the terms, we get:
6400x^2 - 19600x + 422500 = x^2
Solving for x, we get:
x = 25 seconds
Substituting this value back into the equation for the distance the police car travels, we get:
y = 80 * 25 = 2000 ft
What is the solution of the system of equations 6x 2y 4 9x 3y 12?
The solution of the given system of equations 6x + 2y = 4 , 9x -3 y = 12 is equal to x =1 and y = -1.
As given in the question,
Given system of equations are :
6x + 2y = 4 ____(1)
9x -3 y = 12 _____(2)
Multiply (1) by 3 and (2) by 2 and add equation (1) and (2) to eliminate y variable and get the value of variable x ,
18x + 6y = 12
18x - 6y = 24
36x = 36
⇒x = 36 / 36
⇒ x = 1
Substitute value of x = 1 in the given equation (1) to get the value of variable y,
6(1) + 2y = 4
⇒ 6 + 2y = 4
⇒ 2y = 4 - 6
⇒ y = -1
Therefore, given system of equations 6x + 2y = 4 , 9x -3 y = 12 solution is equal to x = 1 and y = - 1.
The above question is incomplete, the complete question is:
What is the solution of the system of equations 6x + 2y = 4 , 9x -3 y = 12?
