Answer:
Step-by-step explanation:
a - 2.5 = 4.5
2.5 = 2.5
a = 7.0 or 7
7.0 - 2.5 = 4.5
4.5 = 4.5
100-10=90
90÷2=45
Mr Bergen's age=45+10
=55 years old
Mrs Bergen's age=45 years old
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
16 because two negatives numbers equal a possitive so 16
Answer: 0
Step-by-step explanation:
The probability of event A happening, then event B, is the probability of event A happening times the probability of event B happening given that event A already happened.
In this case, event A is the Captain hitting the pirate ship and event B is the pirate hitting the Captain's ship.
The Captain fires first, so his ship can't be sunk before he fires his cannons.
So, the probability of the Captain hitting the pirate ship is 2/5
If the Captain hit the pirate ship, the pirate has no chance of firing back.
So, the probability of the pirate hitting the Captain's ship given the Captain hitting the pirate ship is 0.
