Answer:
The train A weighs 137 tons and train B weighs 60 tons.
Step-by-step explanation:
We are given the following in the question:
There are two trains.
Train A and Train B.
Let x tons be the weight of train A and y tons be the weight of train B.
Total weight = 197 tons.
Thus, we can write the equation:
Train A is heavier than train B.
The difference of their weights is 77 tons.
Thus, we can write the equation:
Solving the two equations, we get,
Thus, the train A weighs 137 tons and train B weighs 60 tons.

Answer:
False.
Step-by-step explanation:
We have the statement:
"a relation is a set of ordered pairs where the first element is called the ranged while the second element is the domain"
A relation between two sets maps the elements of the first set into elements of the second set, creating an ordered pair.
So we can have a relation that maps elements X, into elements Y, and the ordered pairs will be (X, Y)
Where the set of the elements X is called the domain, and the set of elements Y is called the range.
Then the statement is false.
the number not located between √9/3 and 2π on the number line is π/9 (option C)
Explanation:
We need to find the numbers between √9/3 and 2π
(√9)/3 = 3/3 = 1
using π as 3.14
2π = 2(3.14) = 6.28
Now we need to check the options for numbers that do not fall between 1 and 6.28:
a) π = 3.14
This number falls between 1 and 6.28
b) √9 = 3
This number falls between 1 and 6.28
c) π/9 = 3.14/9 = 0.35 (approximately)
This number doesnot fall between 1 and 6.28
d) π²/9 = (3.14)²/9 = 1.10 (approximately)
This number falls between 1 and 6.28
Hence, the number not located between √9/3 and 2π on the number line is π/9 (option C)
Answer:
Acute angle
Step-by-step explanation:
170-100=70
An angle between 0 and 90 degrees is an acute angle.
