Answer:
Weight of Train A = A = 237 tons
Weight of Train B = B = 96 tons
Step-by-step explanation:
Two trains train a and be weigh a total of 333 tons. Train A is heavier than train B.The difference of their weight is 141 tons… What is the weight of each train??
Let us represent:
Weight of Train A = A
Weight of Train B = B
Our system of Equations is given as:
A + B = 333 tons..... Equation 1
A - B = 141 tons....... Equation 2
We solve using Elimination method
We Add Equation 1 and 2 together to Eliminate B
Hence:
2A = 474 tons
A = 474 tons/2
A = 237 tons
Solving for B using Equation 1
A + B = 333 tons..... Equation 1
237 tons + B = 333 tons
B = 333 tons - 237 tons
B = 96 tons
Therefore:
Weight of Train A = A = 237 tons
Weight of Train B = B = 96 tons

What is the slope of a vertical line?
What is the slope of a horizontal line?
Answer:
The slope of a vertical line is undefined. The slope of a horizontal line is 0
Step-by-step explanation:
Slope is rise/run
and the rise of a horizontal line is zero since it neither increases nor decreases; therefore, the slope is zero. while a vertical line has undefined slope since it does not run horizontally because division by zero is an undefined operation.

Answer:
x = sqrt(147)
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
x^2 +7^2 = 14^2
x^2 +49 = 196
Subtract 49 from each side
x^2 = 147
Take the square root of each side
sqrt(x^2) = sqrt(147)
x = sqrt(147)
Answer:
[tex]7\sqrt{3}[/tex] or 12.12
Step-by-step explanation:
The pythagorean theorem states that a^2 + b^2 = c^2, with a and b representing the legs and c representing the hypotenuse.
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 = 147
x = [tex]7\sqrt{3}[/tex] or 12.12

In a circle, if you connect the edge of diameter and a point on the circumference, it forms a right triangle.
Is the above statement always true? sometimes true? or always false? Show your answer and support it by reasoning. (can use a picture)
Answer:
always true
Step-by-step explanation:
A group of students stood in a circle to play a game. The circle had a diameter of 15 meters. Which measurement is closest to the circumference of the circle in meters?
Answer: 47cm
Step-by-step explanation:
Thw circumference of a circle is given as: = 2πr or πd
where
π = 3.142
d = diameter = 15 meters
Circumference = πd = 3.142 × 15
= 47.13 cm
= 47cm
There is 3 4 of an apple pie left from dinner. Tomorrow, Victor plans to eat 1 4 of the pie that was left. Enter how much of the whole pie he will eat tomorrow.
Answer:
3/16
Step-by-step explanation:
Let the size of the whole apple be T
Given that 3/4 of the apple is left, it means the size left
= 3T/4
Since Victor plans to eat 1/4 of the pie that was left, this amounts to
1/4 * 3T/4
= 3T/16
This means that Victor will eat 3/16 of the whole pie tomorrow

If a ball has a rebound ratio of 0, what does that mean?
Answer: The test is conducted with an electromagnetic or vacuum release mechanism which releases a soccer ball from a height of 2 meters. From that the height of the rebound is measured by recording the sound of the first and second bounce. The time between the first and second bounce is measured. Also During a collision, some of the ball's energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height. ... It reaches way higher than from the height it was released.

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 3672 no votes what was the total number of votes
Answer: 10,098 votes
Step-by-step explanation:
The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.
To find the total votes, add the ratios:
= 7 + 4
= 11
4/11 are the no votes out of the total. Assuming the total is x, the formula is:
4/11x = 3,672
x = 3,672 / 4/11
x = 10,098 votes

These numbers are common multiples of ________.
6, 12, 18, 36
A) 2 and 4
B) 2 and 3
C) 3 and 4
D) 4 and 6
From this list, we can see that all the numbers are multiples of 2 and 3. So, the correct answer is option B) 2 and 3.
What are common multiples?
Common multiples are multiples that two or more numbers have in common. In other words, common multiples are numbers that are multiples of two or more given numbers.
To find the common multiples of 6, 12, 18, and 36, we can start by finding the prime factorization of each number:
6 = 2 x 3
12 = [tex]2^2[/tex] x 3
18 = 2 x [tex]3^2[/tex]
36 = [tex]2^2[/tex] x [tex]3^2[/tex]
To find the common multiples, we need to list the multiples of the largest number, which is 36, and check which ones are also multiples of the other numbers:
Multiples of 36: 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, 396, ...
Therefore, From this list, we can see that all the numbers are multiples of 2 and 3. So, the correct answer is option B) 2 and 3.
