Triangle ABC is congruent to Triangle EFG.
The length of AB is 4 cm, the length of BC is 12 cm and the length of EF is 12 cm.
Which would be the value of the side FG?
A. 36 cm
B. 3 cm
C. 4 cm
D. 24 cm
Answers
Answer: A. 36
Step-by-step explanation:
The order of the letters matter.
ABC is similar to EFG
AB similar to EF > AB is first 2 letter of first triangle and EF first 2 of
2nd triangle
BC similar to FG >BC is second 2 letter and FG is 2nd 2 letters
AB = 4 and EF = 12 > similar sides EF is 3 times bigger, that means that
the scale factor is 3, EFG, all sides are 3 times
bigger
If the scale factor is 3
And
BC= 12 then FG = 12 x3 = 36
FG= 36
Answer:36

Suppose that the distance a car travels varies directly with the amount of gasoline it uses. A certain car uses 19 gallons of gasoline to travel 380 miles. If the car travels 240 miles, how much gasoline does it need?
Answers
To find out how much gasoline the car needs to travel 240 miles, we can first determine the rate at which the car consumes gasoline. We can do this by dividing the distance traveled (380 miles) by the amount of gasoline used (19 gallons): 380 miles / 19 gallons = 20 miles per gallon (mpg). This means that for every gallon of gasoline, the car can travel 20 miles.
Now that we know the car's fuel efficiency, we can calculate the amount of gasoline needed to travel 240 miles. We do this by dividing the desired distance (240 miles) by the car's fuel efficiency (20 mpg): 240 miles / 20 mpg = 12 gallons. Therefore, the car would need 12 gallons of gasoline to travel 240 miles.
It's interesting to note that the car's fuel efficiency plays a significant role in determining the amount of gasoline needed for a given distance. A more fuel-efficient car would require less gasoline to cover the same distance, ultimately saving the driver money on fuel costs and reducing the environmental impact of driving.

Answer:
Y= mx + b
so Y = 1/3x + 2
just substitute
Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.
Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

In the diagram below, all angles are given in degrees (°)
Find the value of x.
Answers
Answer:
[tex]x=20^o[/tex]
Step-by-step explanation:
from the diagram, we can define the remaining angle in the quadrilateral through the sum of angles in any quadrilateral, which is [tex]360^o[/tex], so the remaining unknown angle should be:
[tex]360-(50+2x+x)=310-3x[/tex]
now that we have the unknown angle, we can find x through the point at which the outer angle is. [tex]x+90[/tex] degrees. (sum of angles at one point is 360 degrees)
[tex]310-3x +x+90=360\\\\400-2x=360\\2x=400-360\\x=20^o[/tex]
The value of variable x is,
x = 20
We have to given that,
In the diagram below, all angles are given in degrees.
Since, the sum of angles in any quadrilateral is, 360 degree.
Let measure of fourth angle is, y
Hence, We get;
(50 + 2x + y + x ) = 360
50 + 3x + y = 360
3x + y = 360 - 50
3x + y = 310
y = 310 - 3x
Now, We get;
(310 - 3x) + (x + 90) = 360
Solve for x,
310 - 3x + x + 90 = 360
400 - 2x = 360
400 - 360 = 2x
2x = 40
x = 40/2
x = 20
Therefore, The solution is, 20

Adrian is throwing a ball into a pail. With 50 attempts, the ball goes into the pail and stays 8 times, goes into the pail and bounces out 6 times, and misses the pail 36 times. If Adrian throws the ball again, what is the probability of each outcome?
Probability the ball goes into the pail and stays =
Probability the ball goes into the pail and bounces out =
Probability the ball misses the pail =
Answers
The probability the ball goes in to the pail and bounces out is 12%
The probability the ball misses the pail is 72%
STEPS:
Divide each number by 50.
36 divided by 50: 0.72
6 divided by 50: 0.12
8 divided by 50: 0.16
Remove the 0’s from the numbers
0.72 -> 72
0.12 -> 12
0.16 -> 16
We want to make sure that all these numbers equal 100 because 100% is 50 in this equation.
12 + 16 + 72 = 100
Because those numbers equal 100, 50 is equal to 100%
Hope this helps!
Answer:
The approximate probability that the ball goes into the pail and stays is 8/50 or 4/25.The approximate probability that the ball goes into the pail and bounces out is 6/50 or 3/25. The approximate probability that the ball misses the pail is 36/50 or 18/25.Step-by-step explanation:
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed. It is based on the results of an experiment or a simulation. For example, if you toss a coin 10 times and get 7 heads and 3 tails, the experimental probability of getting heads is 7/10 = 0.7. This may not match the theoretical probability of getting heads, which is 1/2 = 0.5, because of random variation or error. The more trials you perform, the closer the experimental probability will get to the theoretical probability.
To find the probability of each outcome, we need to divide the number of times the outcome occurred by the total number of trials. Using the given data, we can calculate the probabilities as follows:
The probability the ball goes into the pail and stays = 8/50 = 0.16 The probability the ball goes into the pail and bounces out = 6/50 = 0.12 The probability the ball misses the pail = 36/50 = 0.72We can check that these probabilities add up to 1, which means they are valid.

It takes 17 seconds for a train to pass a 206-meter long bridge at normal speed. It takes 45 seconds for the same train to pass 170-meter long bridge at one-third of the normal speed. What is the length of the train in meters?
Answers
Answer:hello
Step-by-step explanation:sync bien
- L = length of the train in meters
- v = speed of the train in meters per second (normal speed)
- t1 = time taken by the train to pass the 206-meter long bridge at normal speed
- t2 = time taken by the train to pass the 170-meter long bridge at one-third of the normal speed
From the problem statement, we have two equations involving these variables:
Equation 1: L + 206 = v * t1
Equation 2: L + 170 = (1/3)*v * t2
We can solve this system of equations for L by eliminating v. To do this, we can rearrange Equation 1 to solve for v:
v = (L + 206) / t1
Then, we can substitute this expression for v into Equation 2:
L + 170 = (1/3)*[(L + 206) / t1] * t2
Multiplying both sides by 3*t1 and simplifying, we get:
3*L*t1 + 3*170*t1 = (L + 206)*t2
Expanding the right-hand side and simplifying, we get:
3*L*t1 + 510 = L*t2 + 206*t2
Now, we can solve for L by rearranging terms and simplifying:
L = (206*t2 - 3*170*t1) / (3*t1 - t2)
Substituting the given values, we get:
L = (206*45 - 3*170*17) / (3*17 - 45) = 510
The length of the train is 510 meters.

How many yards are in 4 miles?
Answers
Answer: 4 miles are equal to 7040
Step-by-step explanation:
As we know that the ratio can be simplified and the answer can be obtained,
according to the question 5 miles are equal to 8800.
so, here we arrange the ratio in its format as follows
Step 1:
Miles: Yards
5: 8800
Step 2: here we bring the ratio to its simplest form by dividing by 5 on both sides, that is:
5/5=1
8800/5= 1760
Now we get:
Miles: Yards
1: 1760
Step 3: now as we need to find the answer for 4 miles we need to multiply with 4 on both sides, that is:
Miles: Yards
4: 7040
from here we get the answer as 4 milesequalso 7040 yards.

A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
Then you would continue to solve by graphing.

Jenny is 8 and Sammie is 17.
Let's use j for Jenny and s for Sammie.
Given that Jenny is 9 years younger than Sammie, j = s + 9. Five years ago, Sammie was 4 times older than Jennie, 4(j - 5) = (s - 5).
We'll substitute the value of x from equation 1 in equation 2:
4(s - 9 - 5) = (s - 5)
3s = 51
s = 17
Then, we plug in what we just learned for j = s - 9. This gives us 17 = s - 9, which means that j = 8, because 8 + 9 = 17.
Therefore, Jenny is 8 years old and Sammie 17 is years old.

g43 = 79.5
Step-by-step explanation:
geometric sequence = ar^(n-1), where a is first term and r is common ratio.
g23 = ar^(23-1) = ar^22 = 16.
g28 = ar^27 = 24.
now do g28/g23:
(ar^27) / (ar^22) = 24/16,
a^(1-1) r^(27-22) = 24/16,
a^0 r^5 = 24/16,
r^5 = 24/16 = 1.5,
r = (1.5)^1/5 ≈ 1.084.
ar^22 = 16,
a = 16/(r^22) ≈ 2.687.
so g43 = ar^42 ≈ (2.687)(1.084)^42 = 79.5
