Answer:
400
Step-by-step explanation:
354>=350 and thus is rounded upwards to 400.
Let
= amount of salt (in pounds) in the tank at time
(in minutes). Then
.
Salt flows in at a rate

and flows out at a rate

where 4 quarts = 1 gallon so 13 quarts = 3.25 gallon.
Then the net rate of salt flow is given by the differential equation

which I'll solve with the integrating factor method.



Integrate both sides. By the fundamental theorem of calculus,





After 1 hour = 60 minutes, the tank will contain

pounds of salt.
Answer:
The sample space
Step-by-step explanation:
By definition, the sample space is the set composed by all the possible outcomes of your random variable. In this case, the random variable is 4 sided dice, so the sample space is

Answer: 1.834 ft
Step-by-step explanation:
Given
Walter's first Jump is 5 ft, 9 in.
His second Jump is 3 ft, 11 in.
We know,

Converting inches to feet
First Jump in feet

Second jump

The difference in the measurement of two Jumps is

So, Walter first Jump is 1.834 ft higher than the second Jump
