The ΔABC, ΔFGE, and ΔPQR are congruent by SAS criterion.
Option D is the correct answer.
What is triangle congruency?There are ways to prove that two triangles are congruent.
- Side-Side-Side (SSS) Congruence.
The three sides of one triangle are equal to the corresponding three sides of another triangle.
- Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
- Angle-Side-Angle (ASA) Congruence.
The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.
- Angle-Angle-Side (AAS) Congruence.
We have,
Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
So,
The ΔABC, ΔFGE, and ΔPQR are congruent since there is a congruent angle between the corresponding equal sides in all three triangles.
Thus,
The ΔABC, ΔFGE, and ΔPQR are congruent by SAS.

The city of El Paso is three hundred and twenty miles from the city of Tucson, Arizona, and seven hundred and twenty miles from San Diego, California. Tomorrow I'm going to travel from Tucson to San Diego. I plan to leave Tucson at six in the morning. If I drive 75 miles per hour the first four hours and 50 miles per hour the rest of the way, what time (Tucson time) will I get to San Diego?
We have that El Paso is 320 miles from Tucson and 720 miles from San Diego.
You're travelling from Tucson to San Diego.
First we have to find the distance from Tucson to San Diego. We can do this by finding the difference between the distance of Tucson from San Diego and El Paso from San Diego.
That is:
720−320
400 miles
You leave by 6:00 am.
You drive for 75 miles per hour in 4 hours for the first part of the journey.
You then drive for 50 miles per hour for the rest of the journey.
The first step is to find the distance that the rest of the journey took. We can do that by first finding the distance covered in the first part of the journey and subtracting that from the total distance (400 miles).
To find the distance for the first part of the journey, we apply the formula for speed (rate of change of distance with time):
s = d/t
⇒d = s⋅t
where d= distance; t = time
Therefore:
d=75⋅4
d=300 miles
The first part of the journey covered 300 miles. This means that the rest of the journey covered:
400 - 300 = 100 miles
Now, to find the time the rest of the journey took, we have to apply the same formula for speed:
s=d/t
t=d/s
Therefore:
t=100/50
t=2 hrs
To find the total time it took to complete the journey, we have to add the times for the first part and the rest of the journey.
That is:
T=4+2
T=6 hours
Since you left home by 6:00 am, the time you will get to San Diego is 6 hours after that, i.e. 12 noon (Tucson time)
That is the answer.

Answer:
6/(2+k)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_a(b)=\dfrac{\log(b)}{\log(a)}[/tex]
Using this, we can take the logarithm base 2 in the change of base formula for the given expression.
[tex]\log_{20}(64)=\dfrac{\log_2(64)}{\log_2(20)}=\dfrac{\log_2(2^6)}{\log_2(2^2\cdot5)}\\\\=\dfrac{6}{\log_2(2^2)+\log_2(5)}=\boxed{\dfrac{6}{2+k}}[/tex]
__
In addition to the change of base formula, the usual rules of logarithms apply.
[tex]a^b=m\ \longleftrightarrow \ \log_a(m)=b\\\log(ab)=\log(a)+\log(b)[/tex]
Each of 5 friends got a full box of snacks and an extra 6 snacks. Write an equation to show how many snacks are in all those boxes and all those extra snacks.
Solve each inequality.
1. 5x + 2 <17
Answer:
x<3
Step-by-step explanation:
5x+2<17
Subtract 2 from both sides.
5x<17−2
Subtract 2 from 17 to get 15.
5x<15
Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.
x=15/5
Divide 15 by 5 to get 3.
x<3
The image below shows four soccer balls at different
locations on an uneven soccer field. Which ball has the
greatest amount of kinetic energy? Explain your answer.
Answer: letter d
Step-by-step explanation:
Answer:
Ball D. Among the four balls in this picture, ball D is the only one whose kinetic energy is greater than [tex]0[/tex].
Step-by-step explanation:
Consider an object of mass [tex]m[/tex]. If this object is moving at a speed of [tex]v[/tex], the kinetic energy of this object would be:
[tex]\displaystyle \frac{1}{2}\, m \cdot v^{2}[/tex].
The speed [tex]v[/tex] of ball A, B, and C are all [tex]0[/tex]. Hence, the kinetic energy of these three balls would be [tex]0\![/tex].
The speed of ball D is greater than [tex]0[/tex]: [tex]v = 2\; \rm m \cdot s^{-1}[/tex]. The kinetic energy of this ball would be:
[tex]\begin{aligned} {\rm KE} &= \frac{1}{2}\, m \cdot v^{2} \\ &= \frac{1}{2}\times \rm 0.43\; \rm kg \times \left(2\; \rm m \cdot s^{-1}\right)^{2}\\ &= 0.86\; \rm J\end{aligned}[/tex].
Hence, the kinetic energy of ball D is the greatest among the four balls in this picture.

You know that in a specific population of rainbow trout 15% of the individuals carry intestinal parasites. Assume you obtain a random sample of 9 individuals from this population:a. Calculate the probability that __ (last digit of your ID number) carry intestinal parasites.b. Calculate the probability that at least two individuals carry intestinal parasites.
Answer:
a) 0.2316 = 23.16% probability that 0 carry intestinal parasites.
b) 0.4005 = 40.05% probability that at least two individuals carry intestinal parasites.
Step-by-step explanation:
For each trout, there are only two possible outcomes. Either they carry intestinal parasites, or they do not. Trouts are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
You know that in a specific population of rainbow trout 15% of the individuals carry intestinal parasites.
This means that [tex]p = 0.15[/tex]
Assume you obtain a random sample of 9 individuals from this population:
This means that [tex]n = 9[/tex]
a. Calculate the probability that __ (last digit of your ID number) carry intestinal parasites.
Last digit is 0, so:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{9,0}.(0.15)^{0}.(0.85)^{9} = 0.2316[/tex]
0.2316 = 23.16% probability that 0 carry intestinal parasites.
b. Calculate the probability that at least two individuals carry intestinal parasites.
This is
[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]
In which
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{9,0}.(0.15)^{0}.(0.85)^{9} = 0.2316[/tex]
[tex]P(X = 1) = C_{9,1}.(0.15)^{1}.(0.85)^{8} = 0.3679[/tex]
[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.2316 + 0.3679 = 0.5995[/tex]
[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.5995 = 0.4005[/tex]
0.4005 = 40.05% probability that at least two individuals carry intestinal parasites.
We will see that the probabilities are:
a) 3.8*10^-8b) 0.26How to find the probability.
We know that 15% of the population have the parasites, then if we take a trout at random we have:
a probability of 0.15 that it has parasites.a probability of 0.85 that it does not have parasites.a) The probability that 9 of them carry intestinal parasites (so all of them have).
This is just the product of the individual probabilities, so we have 9 times a probability of 0.15, this gives:
P(9) = (0.15)^9 = 3.8*10^-8
b) Probability that 2 out of 9 have parasites.
Then we have 0.15 two times, and 0.85 seven times.
But we also need to take in account the permutations, the different groups of 2 trouts that we can make out of 9 trouts is given by:
[tex]C(9, 2) = \frac{9!}{(9-2)!*2!} = \frac{9*8}{2} = 36[/tex]
This means that there are 36 different pairs of 2 trouts that can be the ones with parasites.
Then the probability that 2 trouts have parasites is:
P(2) = 36*(0.15)^2*(0.85)^7 = 0.26
And just to be complete, the probabilty that x trouts have parasites is:
P(x) = C(9, x)*(0.15)^x*(0.85)^(9 - x)

Answer:
x = 14.5°
Step-by-step explanation:
A+D = 180°
(8x-11) + (5y+2) = 180°
simplify:
5y + 8x = 189°
5y = 189 - 8x
D = B
(5y+2) = (4x+17)
simplify
5y = 4x + 15
then:
189 - 8x = 4x + 15
12x = 174
x = 14.5°
5y = 4(14.5) + 15
5y = 73
y = 14.6
check:
5(14.6) + 8(14.5) = 189
73 + 116 = 189
189 = 189

Step-by-step explanation:
The question asks which one would always form an image that is congruent to the pre-image.
Note that Translation, Reflection, and Rotation do not change the size or shape of the pre-image while Dilation will change the size of your pre-image.
Therefore, the most likely answer would be options D and E that do not include dilation in their series of transformations so the image will not change its size making it congruent to the pre-image.

Answer:
Estimated time = 490 seconds
Exact time = 463.98 seconds
Step-by-step explanation:
The car traveled 1 mile in 70.3 seconds.
We want to find how long it took to travel 6.6 miles.
We are told to estimate the given values to the nearest whole numbers before solving.
Thus;
1 mile was travelled in 70 seconds
Then; 6.6 miles ≈ 7 miles
Thus, 7 miles is travelled in; 70 × 7/1 = 490 seconds
Estimated time = 490 seconds
Now, exact time will be;
Exact time = 70.3 × 6.6/1
Exact time = 463.98 seconds
total of 342 tickets were sold for school play. They were either adults tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answer:
684 I think ?!
Step-by-step explanation:
Answer: 114 adult tickets were sold.
Step-by-step explanation:
Let student tickets be represented as 2t (since twice the amount of student tickets were sold)
and let t represent the amount of adult tickets.
Solve for t (number of tickets)
342= 2t + t. Combine like terms.
342= 3t. Divide both sides by 3.
114=t
114 adult tickets were sold.
Substitute 114 for t to find student tickets.
2(114)= 228 student tickets were sold.
