Answer:
1. true 2. true 3.true 4. false 5. false
Step-by-step explanation: 4/4-3/4 is 1/5. You multiply the top first (4-3=1) and the bottom isn't supposed to change. so the answer is 1/4
The tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a chess tournament starts at 12:30 p.m. and ends at 5:00 p.m.
The difference between 12:30 p.m. and 5:00 p.m. can be calculated after changing time into 24 hours clock
12:30 p.m. = 12 hours 30 minutes = 12.50
5: 00 p.m. = 17 hours 00 minutes = 17.00
Difference between them:
= 17.00 - 12.50
= 4.5 hours
4.5 < 5
Thus, the tournament does not last more than 5 hours because the duration of the tournament is 4.5 hours.

You are trying to find the difference that equals 3 and is near those range of numbers.
The numbers are 11 and 14.
Ф = 3π/4. Transform it into Rectangular (or Cartesian) form .
The coordinates of Ф are x ,y in rectangular form ==> so:
tan(Ф) = y/x and y=x . tan(Ф) ==> y= x. tan(3π/4). we know that tan(3π/4)= - 1
Hence y = - x
