Answer:
£152.
Step-by-step explanation:
We have been given that a bottle contains 255 coins. 1/3 of the coins are £1.00.
Let us find 1/3 of 255 to find the number of £1 coins.

This means we have £85.
We are also told that 110 of the coins are 50 p coins.


Let us figure out number of 20 p coins by subtracting the number of £1 coins and 50 p coins from 255.





Now let us find total value of the coins contained in the bottle by adding the values of £1 coins, 50 p coins and 20 p coins.


Therefore, the total value of the coins contained in the bottle is £152.
For this case we find the slopes of each of the lines:
The g line passes through the following points:

So, the slope is:

Line h passes through the following points:

So, the slope is:

By definition, if two lines are parallel then their slopes are equal. If the lines are perpendicular then the product of their slopes is -1.
It is observed that lines g and h are not parallel. We verify if they are perpendicular:

Thus, the lines are perpendicular.
Answer:
The lines are perpendicular.
Answer:
y = mx + b
Step-by-step explanation:
The reason is, x is always the hour, and m is the amount of money you earn in the hours.
B as it goes through the correct and average amount of points on the graph, hope this helps
