Answer:
1/6 ton of fish is fed during the feeding at night.
Step-by-step explanation:
The fish fed in the morning is 
tons, and during after noon the fish fed is 
more than in the morning; or
and let us call the tons of fish fed at night 
, then if the total tons of wish fed during the is 
, we have
Let us add the numerators on the left side and we get:
and subtract 
from both side to isolate 
and since 
, we have
the common denominator of the fractions is 6; therefore, we rewrite the equation as
and subtract the numerators to get:
which the number of tons fed during the feeding at night.
Increasing is= [0,90], [270,360]
Decreasing is=[90,270]

Answer:
69 3/4
Step-by-step explanation:
The stock market goes down to 50 3/4 at the beginning of the day
At the end of the day it goes up to 120 1/2
Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows
= 120 1/2 - 50 3/4
= 241/2 - 203/4
= 279/4
= 69 3/4
Hence the total change in the stock market from the beginning to the end of the day is
69 3/4
1] ⬇
p - (6 - 2(q))➡0
p + 2q - 6➡0
q = 3 because 6÷2 = 0
p = 6 because 6 ÷ 1 = 6
Slope ➡ 0.5
-----------------------------------------------------------------
2] ⬇
p - (1 + q)➡0
p - q- 1➡0
Q = -1 because 1 ÷ -1 ='-1
P = 1 because 1 ÷ 1 = 1
Slope ➡ 1
