You purchased concentrated cleaner that must be diluted before use. Container a is the cleaner, which is 20% solution. Container b is pure water. You are mixing together the contents of container a and container b to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution?
Answer:
18 gallons from container [tex]a[/tex] and 22 gallons from the container [tex]b[/tex] to be mixed to get the required mixture.
Step-by-step explanation:
Given that the container [tex]a[/tex] has 20% concentrated cleaner
and container [tex]b[/tex] has pure water which has 0% cleaner.
Let x gallons from container a and y gallons from the container b are mixed to get a 9% concentrated solution.
So,
[tex]9\%\; \text{of}\; (x+y) = (20\% \; \text{of}\; x )+(0\% \; \text{of}\; y)\cdots(i)[/tex]
As the total amount of the final solution= 40 gallons
So, [tex]x+y=40\cdots(ii)[/tex]
Using the value of equation (ii) in equation (i), we have
9% of 40 = 20% of x
[tex]\Rightarrow 0.09\times 40=0.2 \times x[/tex]
[tex]\Rightarrow x=\frac{0.09\times 40}{0.2}[/tex]
[tex]\Rightarrow x=18[/tex] gallons.
From equation (ii),
18+y=40
[tex]\Rightarrow y=40-18=22[/tex] gallons.
Hence, 18 gallons from container [tex]a[/tex] and 22 gallons from the container [tex]b[/tex] to be mixed to get the required mixture.

3) g(8) = 28
4) f(3) = 18
Step-by-step explanation:
plug in 8 as x. 5(8)- 12 --> 40 -12 = 28.
plug in 3 as x. 2x² --> 2(3)^2--> 2(9) = 18.
Ina certain county weights of women are normally distributed with a mean of 138 lb and a standard deviation of 15 lb. What percentage of women in that country weigh more than 120 lb
Answer:
88.493%
Step-by-step explanation:
We solve this question using z score formula.
Z score = x - μ/σ
where
x is the raw score = 120lb
μ is the population mean = 138lb
σ is the population standard deviation = 15lb
Hence,
z = 120 - 138/15
= -1.2
Probability value from Z-Table:
P(x<120) = 0.11507
P(x>120) = 1 - P(x<120)
1 - 0.11507
= 0.88493
Converting to percentage
= 0.88493 × 100
= 88.493%
The percentage of women in that country weigh more than 120 lb is 88.493%
Gribbles are small, pale white, marine worms that bore through wood. While sometimes considered a pest since they can wreck wooden docks and piers, they are now being studied to determine whether the enzyme they secrete will allow us to turn inedible wood and plant waste into biofuel.1 A sample of 50 gribbles finds an average length of 3.1 mm with a standard deviation of 0.72. Give a best estimate for the length of gribbles, a margin of error for this estimate (with 99% confidence), and a 99% confidence interval. Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. point estimate = Enter your answer; point estimate margin of error = Enter your answer; margin of error The 99% confidence interval is Enter your answer; The 99%confidence interval, value 1 to Enter your answer; The 99%confidence interval, value 2
Answer:
a) The Margin of Error = 0.26
b) The 99% Confidence Interval = ( 2.84, 3.36)
Step-by-step explanation:
a) Margin of Error
The formula for Margin of Error =
z × Standard deviation/√n
From the above question
The z score for 99% confidence interval = 2.576
Standard deviation = 0.72
n = Random number of samples = 50
Margin of Error =
2.576 × 0.72/√50
= 1.85472 /√(50)
= 0.2622970178
Approximately to 2 decimal places = 0.26
b) 99% Confidence Interval
= Mean ± Margin of Error
Mean = 3.1mm
Confidence Interval = 3.1 ± 0.26
3.1 ± 0.26
= 2.84
3.1 + 0.26
= 3.36
The 99% Confidence Interval = ( 2.84, 3.36)

Solve for x by factoring
X^2+4x-21=0
There are multiple answers
Answer:
[tex]x=3,-7[/tex]
Step-by-step explanation:
We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]
By applying this on the quadratic equation, we get:
[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]
Which simplifies to:
[tex]x=\frac{-4\pm10}{2}[/tex]
[tex]\therefore x=3,-7[/tex]
5. You are buying orange juice for $3.50 per container and have a gift card worth $5. The function f(x) = 3.50x-5 represents your total cost f(x) if you buy x containers of orange juice and use the gift card. How much would you pay for 4 containers of orange juice?
Answer:
$9
Step-by-step explanation:
If you do 3.5*4 then you get 14. You then use the $5 gift card so you subtract 5 from 14 and get 9
using the equation, that would be f(x) = (3.5*4)-5. Using PEMDAS, you would do the parenthesis first so it would be f(x) = 14-5 which equals 9
The cost of a gym membership is $25 per month. There is an initial fee of $40
Answer:
y = 25x + 40
Step-by-step explanation:
Using the formula, y = mx + b we can find out what this equation would be.
m = the rate of change/slope
b = the y- intercept
25 per month is telling us that this is the rate of change.
Since the $40 is only paid once, you can tell that this is the y intercept.
The equation will look like:
y = 25x + 40
On a graph it would look like:
Let the total cost of a gym membership be y, with the number of months as x.
The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).
y = 40 + 25x

I need to rearrange the variables to solve for pressure, P, as a function of volume and temperature, V and T. Write out your work on paper and submit a picture.
Answer:
P = (8T) / V
Step-by-step explanation:
P*V=8*T*P/P multiply both sides by P
P*V=8*T because P/P=1
P = 8T/V divide both sides by V
