Step-by-step explanation:
It is a good idea to try to save up money to buy large items or find 0% interest deals so
you are not paying interest. However, this is not always possible, especially when buying
a house or car. That is when it is important to understand how much interest you will be
charged on your loan.
In 2 seconds it travels 160 meters
2y+4=6
First, subtract the 4 from both sides:
2y+4-4=6-4
Simplify:
2y=2
Divide both sides by 2:
y=1
Answer:
Hence, the distance between two walls is:
100 m.
Step-by-step explanation:
We are asked to find the distance between the two balls.
This could be done if we first find the distance between the first wall and the laser bean=d
and then the second wall and the laser bean=d'
and then add both the distances to find the total distance between the two walls i.e. (d+d')
As the triangle is right triangle so we will use the trignometric identity to find the distance.
The distance between the first wall and laser beam is:
similarly The distance between the second wall and laser beam is:
Hence, the distance between the two walls is:
Hence, the distance between two walls is:
100 m.
