What evidence is needed to prove two triangles are similar by the SSS similarity theorem?
Answers
Consider the same figure as given above. It is observed that DP/PE = DQ/QF and also in the triangle DEF, the line PQ is parallel to the line EF.
So, ∠P = ∠E and ∠Q = ∠F.
Hence, we can write: DP/DE = DQ/DF= PQ/EF.
The above expression is written as
DP/DE = DQ/DF=BC/EF.
It means that PQ = BC.
Hence, the triangle ABC is congruent to the triangle DPQ.
(i.e) ∆ ABC ≅ ∆ DPQ.
Thus, by using the AAA criterion for similarity of the triangle, we can say that
∠A = ∠D, ∠B = ∠E and ∠C = ∠F.

in how many ways can three different integers be selected from 1 - 10 such that no two integers chosen are consecutive
Answers
There are 56 different ways to select three different integers from 1 to 10 such that no two chosen integers are consecutive.
To determine the number of ways to select three different integers from 1 to 10 such that no two chosen integers are consecutive, we can use combinatorics principles.
First, let's consider the total number of ways to choose three integers without any restrictions. This can be calculated using the combination formula:
C(n, r) = n! / (r!(n-r)!)
In this case, we have 10 integers to choose from, and we want to choose 3. Therefore, the total number of ways to choose three integers without any restrictions is:
C(10, 3) = 10! / (3!(10-3)!) = 10! / (3!7!) = 120
Now, let's consider the restricted condition that no two chosen integers can be consecutive. We can approach this by selecting three non-consecutive integers from the available set.
To do this, we can start by choosing any integer, then excluding its two adjacent integers. For example, if we choose 1, we cannot choose 2 or 3. Similarly, if we choose 10, we cannot choose 9 or 8.
Since there are two adjacent integers to exclude for each choice, we have 8 integers remaining to choose from. Therefore, the number of ways to select three non-consecutive integers is:
C(8, 3) = 8! / (3!(8-3)!) = 8! / (3!5!) = 56

One light flashes every 18 seconds and another light flashes every 12 seconds. If they flash together at 8:00 p.M., what is the next time that they will flash together?
Answers
Answer:
They will flash together at 36 seconds after 8:00 p.M which can be written as 8:00:36 PM.
Step-by-step explanation:
This question can be solved using concept of LCM
LCM is the least number which is divisible by all the set of given number.
LCM is found by finding the prime factors of given set of numbers and then taking the each numbers highest power and then multiplying all.
for example
lets find LCM of 20 and 75
prime factor of 20 = 2*2*5
prime factor of 75 = 3*5*5
highest power of 2 is 2*2 = 4
highest power of 3 is 3 = 3
highest power of 5 is 5*5 = 25
thus LCM is 4*3*25 = 300
Thus, 300 is the least number which will be commonly divisible by 20 and 75.
Now in the problem given One light flashes every 18 seconds and another light flashes every 12 seconds.
Thus, they will will flast together at time when the time will be commonly divisible by both 12 and 18.
to find that time, lets find the LCM of 12 and 18
The number is 12 , 18
prime factor of 12 = 2*2*3
prime factor of 18 = 2*3*3
highest power of 2 is 2*2 = 4
highest power of 3 is 3*3 = 9
thus LCM is 9*4 = 36
Thus, the lights will flash together after 36 seconds.
Given that they flash together at 8:00 p.M
They will flash together at 36 seconds after 8:00 p.M which can be written as 8:00:36 PM.

Answers
The length of each piece of wood will be 28 inches if divided into 25%.
To divide the wood into 4 equal pieces, we will divide the total quantity by 4. Thus, the fraction that we will get is 1/4th of total. Now, as per the known fact, 1/4 is 25%, which will be our required answer based on the criteria mentioned in question.
Length of wood after division = 112/4
Performing division on Right Hand Side of the equation
Length of wood after division = 28 inches

A machine cell uses 196 pounds of a certain material each day. Material is transported in vats that hold 26 pounds each. Cycle time for the vats is about 2.50 hours. The manager has assigned an inefficiency factor of 25 to the cell. The plant operates on an eight-hour day. How many vats will be used? (Round up your answer to the next whole number.)
Answers
The number of vats to be used is 8
Given: Weight of material used per day = 196 pounds
Weight of each vat = 26 pounds
Cycle time for each vat = 2.5 hours
Inefficiency factor assigned by manager = 25%
Time available for each day = 8 hours
To calculate the number of vats to be used, we need to calculate the time required to transport the total material by the available vats.
So, the number of vats required = Total material weight / Weight of each vat
To calculate the total material weight transported in 8 hours, we need to calculate the time required to transport the weight of one vat.
Total time to transport one vat = Cycle time for each vat / Inefficiency factor
Time to transport one vat = 2.5 / 1.25
(25% inefficiency = 1 - 0.25 = 0.75 efficiency factor)
Time to transport one vat = 2 hours
Total number of vats required = Total material weight / Weight of each vat
Total number of vats required = 196 / 26 = 7.54 (approximately)
Therefore, the number of vats to be used is 8 (rounded up to the next whole number).
Answer: 8 vats will be used.

Therefore the balance will be $13.66

Simplify the following expression to remove negative exponents.
Answers
When there is a negative exponent, you switch the side of the fraction it's on. If the negative exponent is the numerator or a whole number, like \(x^{-9}\) or \(\frac{x^{-9} }{3}\), you move the exponent and its coefficient to the bottom so that it's part of the denominator, and remove the negative.
\(x^{-9}\) = \(\frac{1}{x^{9} }\)
\(\frac{x^{-9} }{3}\)= \(\frac{1}{3x^{9} }\)
If the exponent is on the bottom, or part of the denominator, like \(\frac{1}{x^{-4} }\), we move it to the top and take out the negative.
\(\frac{1}{x^{-4} }\) = \(x^{4}\)
In our case, the expression is \(x^{-7}\).
So, using our new knowledge of negative exponents, we can take the exponent and put it as a denominator.
\(x^{-7}\) = \(\frac{1}{x^7}\)
The answer would be the last answer.

Answers
Answer:
Negative 135 divided by negative 7 = 22.5
Step-by-step explanation:
Estimating the quotient of :
–137.56 divided by –6.12
The compatible number which gives the best estimate ;
Negative 140 divided by negative 7 = 20
-140 ÷ - 7 = 20
Negative 140 divided by 6 = 23.3 with bar
-140 ÷ 6 = - 23.3
Negative 135 divided by negative 7 = 22.5
-135 ÷ - 7 = 22.5
Negative 135 divided by negative 5 = 27
-135 ÷ - 5 = 27
Comparing the result with the actual quotient obtained using the actual value;
–137.56 ÷ ( –6.12) = 22.477
Hence,
Negative 135 divided by negative 7 = 22.5
-135 ÷ - 7 = 22.5 gives the closest estimate.

Ethology: The population, P, of fish in a lake t months after a nearby chemical factory commenced operation is given by P = 600(2 + e^-0.2t). Find the number of fish in the lake
(i) in the long run (that is, as t becomes very large).
Answers
Answer:
The number of fish in the lake is given by the equation P = 600(2 + e^-0.2t).
When t = 0, the number of fish is P = 600(2 + e^0) = 600(2 + 1) = 1200.
Therefore, there are 1200 fish in the lake.
As time goes on, the number of fish will decrease exponentially. This is because the chemical factory is polluting the lake, which is killing the fish.
In 10 months, the number of fish will be P = 600(2 + e^-0.2*10) = 600(2 + 0.125) = 750.
In 20 months, the number of fish will be P = 600(2 + e^-0.2*20) = 600(2 + 0.0625) = 675.
As you can see, the number of fish is decreasing rapidly. In just 20 months, the number of fish will have decreased by more than half.
