Answer:
He is watching TV for 2 hours and 40 minutes.
Step-by-step explanation:
We are given that the episodes of a TV program are each 40 minutes long. Phill watches four episodes together.
As it is stated that the length of each episode of a TV program is 40 minutes, so the length of four episodes is given by;
1 episode = 40 minutes
4 episodes = 4
40
= 160 minutes
So, the length of four episodes together is 160 minutes.
Now, we have to convert the time in hours and minutes;
As we know that 1 hour = 60 minutes
160 minutes = 120 minutes + 40 minutes
= 2 hours + 40 minutes
Hence, the length of four episodes together is 2 hours and 40 minutes.
This is prime factorization
we need to know what number might go into 63
Most people who know their times tables remember that 9 * 7 = 63
7 is a prime number so it would go into the circle, and the 9 will go into the box
9 isn't prime, but 3 * 3 = 9. 3 is a prime number so the 3's will go into the circles below the 9.
If you need a final answer you can write 63 = 3 * 3 * 7
You can get the same factors if you use 3 *21 instead of 9*7 at the beginning. I'll let you figure out that one.
P=2 (l+w)
we know P=284
we also know that l= w+50
so replace l in the equation with w+50
284=2 (w+50+w)
284=2 (2w+50)
divide both sides by 2
142=2w+50
subtract 50 on both sides
98=2w
divide both sides by 2
49=w
so width is 49, and we need to add 50 to it to find the length
l= 49 +50
l=99
