The amount of oxygen in the flask through the intake tube illustrates proportions
The flask 99.35% will contain of oxygen after 5L have passed through the intake tube
<h3>How to calculate the percentage of oxygen?</h3>
To do this, we make use of the following representations
- P for the proportion of oxygen
- V for te volume of oxygen
- x for the proportion of oxygen in the flask after 5 L passed through
So. we have the following derivative
dP = dV - P * dV
Divide through by dV
dP/dV = 1 - P
Next, we set up the integral
Integrate both sides
Expand
-ln(|x - 1|) + ln(|0.04 - 1|) = 5
Evaluate the difference
-ln(|x - 1|) + ln(|-0.96|) = 5
Express as a fraction
ln(0.96/|x - 1|) = 5
Express both sides as exponents with a base of 2
e^ln(0.96/|x - 1|) = e^5
Solve for x
x = 1 - 0.96/e^5
Evaluate the difference
x = 0.9935
Express as percentage
x = 99.35%
Hence, the flask 99.35% will contain of oxygen after 5L have passed through the intake tube

Since the numbers are consecutive, they can be represented by:
x, x+1, x+2, x+3, x+4
Their sum is -20 = x+x+1+x+2+x+3+x+4. Result: -20=5x+10, or 5x=-30, or x = -6.
Then the numbers are -6, -5, -4, -3 and -2. These do add up to -20, as required.
The smallest of these is -6.
Answer:
Hence in 52 weeks he will distribute 156 $ with 3 $ per week from his pay
Step-by-step explanation:
Given:
156 $ to United way for a year.
With each weeks.
To Find:
How much amount he will take for pay for giving to United way.
Solution:
He wants to give money to united way in a year
So there are 365 days per year
And he held money from is his pay every week
So there 7 days per weeks.
Hence Total number of weeks in a year will given by,
=365/7
=52 weeks per year
Now he held every week from his pay to United way
And Total amount to distribute is about 156 $ in 52 weeks.
So Every week amount will be
=156$/52
=3 $ /week
Answer:
Step-by-step explanation:
x²+5x+6=x²+3x+2x+6=x(x+3)+2(x+3)=(x+3)(x+2)
so Volume=(x+3)(x+2)(x+4)
V=lwh
one of the factors is the length.
