A pool company claims that for optimal results customers should use 20 cups of 73% chlorine solution to treat their pools unfortunately the company only has an 80% chlorine solution and a 60% chlorine solution In stock how many cups of Each chlorine solution should be mixed to create the optimal solution?
Answer:
13 cups of the 80% chlorine solution + 7 cups of the 60% chlorine solution
Step-by-step explanation:
The pool company recommendation is 20 cups of 73% chlorine to treat their pool
Concentration of chlorine solution in stock = 80% and 60%
Therefore to make 20 cups of 73% solution, we require;
X cups of the 80% chlorine solution and
Y cups of the 60% chlorine solution
That gives 0.8·X + 06·Y = 0.73 × 20
X + Y = 20
Solving gives X = 13 cups
and Y = 7 cups
Therefore to make the optimal solution, 13 cups of the 80% chlorine solution should be mixed with 7 cups of the 60% chlorine solution.
The ratio of boys to girls in a group is 2:1. If there are 22 more boys than girls, work out how many people there are in total
Answer:
66 in total. 44 boys and 22 girls
Step-by-step explanation:
you have to multiply 22 by 2 because there is twice as many (half of two is one) boys than there is girls.
Answer:
66
Step-by-step explanation:
There is a 2:1 ratio of boys to girls, and there are 22 more boys than girls. We can assume that 2/3 of the class are boys while 1/3 of the class is girls.
The difference between the two is 1/3. This can be found by taking away the smaller of the two from the larger, in this case it's 2/3 - 1/3. Removing the third, it's 2-1 which can be done by multiplying the two fractions by three. If we add the third back by dividing by three, we get 1/3.
This means that 22 people must be equivalent to 1/3 the total class' population. If x/3 = 22, then 22 * 3 must be x.
22 * 3 = 66, so there must be 66 students in the class.

Answer:
what is the question
Step-by-step explanation:
Which function has the same graph as y = 2cos(x + pi/4 )?
y = 2sin(x + pi/4 )
y = 2sin(x - pi/4 )
y = 2sin(x + 3pi/4 )
y = 2sin(x - 3pi/4 )
Answer:
y = 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) has the same graph of y = 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) ⇒ 3rd answer
Step-by-step explanation:
Let us revise the rules of the trigonometric compound angles
cos(x + y) = cos x cos y - sin x sin y
sin(x + y) = sin x cos y + cos x sin y
Let us solve the problem using the rules above
y = 2 cos (x + [tex]\frac{\pi }{4}[/tex] )
∵ 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) = 2[cos x cos [tex]\frac{\pi }{4}[/tex] - sin x sin [tex]\frac{\pi }{4}[/tex] ]
∵ cos [tex]\frac{\pi }{4}[/tex] = [tex]\frac{\sqrt{2}}{2}[/tex] and sin [tex]\frac{\pi }{4}[/tex] = [tex]\frac{\sqrt{2}}{2}[/tex]
- Substitute them in the right hand side
∴ 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) = 2[ [tex]\frac{\sqrt{2}}{2}[/tex] cos x - [tex]\frac{\sqrt{2}}{2}[/tex] sin x]
- Multiply the bracket in the right hand side by 2
∴ 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
∴ y = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
Now let us find the function which give the same right hand side of the function above
y = 2 sin (x + [tex]\frac{3\pi }{4}[/tex] )
∵ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = 2[sin x cos [tex]\frac{3\pi }{4}[/tex] + cos x sin [tex]\frac{3\pi }{4}[/tex] ]
∵ sin [tex]\frac{3\pi }{4}[/tex] = [tex]\frac{\sqrt{2}}{2}[/tex] and cos [tex]\frac{3\pi }{4}[/tex] = [tex]-\frac{\sqrt{2}}{2}[/tex]
- Substitute them in the right hand side
∴ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = 2[ [tex]-\frac{\sqrt{2}}{2}[/tex] sin x + [tex]\frac{\sqrt{2}}{2}[/tex] cos x]
- Multiply the bracket in the right hand side by 2
∴ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = [tex]-\sqrt{2}[/tex] sin x + [tex]\sqrt{2}[/tex] cos x
- Switch the two terms of the right hand side
∴ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
∴ y = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
- The same with right hand side of the function above
∴ y = 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) has the same graph of y = 2 cos (x + [tex]\frac{\pi }{4}[/tex] )
Answer:
y=2sin(x+3pi/4)

Estimate the result by rounding the numbers to the second decimal before performing the operation. Then also round your answer to the second decimal. 8123÷0.211 How do you do it?
Answer:
40615
Step-by-step explanation:
Note, rounding off decimals involves observing if the said decimal is up to the value of 5. If it is, then it can be rounded up, if not, its rounded off.
Since we need to round the numbers to the second decimal before performing the operation, we will have, 8123÷0.2
Note, 8123 has no decimal so we ignore
But 0.211 has a second decimal which is the first 1 so because it's not up to 5, we round it off to 0.
Hence we have 8123 ÷ 0.2= 40615.0
Since our answer has no decimal, we leave it like that.
Answer:
38680.95
Step-by-step explanation:
Solution:-
- We will round the denominator of the fraction " 0.211 " to two decimal places.
0 . 2 1 1
1st 2nd 3rd
3rd digit = 1 < 5 ... "Truncate the 3rd decimal value and on wards"
ans: 0.21
- Now perform the division:
8123 / 0.21 = 38680.95238
- Now again round the resulting answer to 2nd decimal place:
38680. 9 5 2
1st 2nd 3rd
3rd digit = 2 < 5 ... "Truncate the 3rd decimal value and on wards"
- The resulting answer will be after rounding to 2nd decimal place:

Raj polled 100 students in his class to compare the number of hours that teen boys and girls played video games each week. The results of his survey are shown below. Which gender shows greater variability in their playing time?
Hours of Video Game Time per Week for Teen Boys
A box-and-whisker plot. The number line goes from 0 to 28. The whiskers range from 0 to 28, and the box ranges from 9 to 17. A line divides the box at 14.5.
Hours of Video Game Time per Week for Teen Girls
A box-and-whisker plot. The number line goes from 0 to 28. The whiskers range from 0 to 28, and the box ranges from 3 to 15. A line divides the box at 6.
Boys show greater variability because the 3rd quartile for boys is 17 but only 15 for girls.
Boys show greater variability because the median playing time for boys is 14.5 but only 6 for girls.
Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.
Girls show greater variability because the data for the girls is skewed toward the lower end of the box plot.
The gender that shows greater variability in their playing time is females (teen girls).
How can we measure variability in a box-plot?It may depend on conditions. The dispersion can be measured in many ways. We can find range (max value - min. value), or interquartile range(the absolute difference between the first and third quartile ), etc to measure the variability.
How does a boxplot shows the data points?A box plot has 5 data description.
The leftmost whisker shows the minimum value in the data.The rightmost whisker shows the maximum value in the data.The leftmost line in the box shows the first quartile.The middle line shows the median, also called second quartile.The last line of the box shows the third quartile.How to find the interquartile range?IQR(inter quartile range) is the dfference between third and first quartile.
We will use the interquartile range here to find the variability in the playing time taken by different genders.
From the box plots given, we get the data of first and third quartiles from the left and right limits of boxes.
For males (teen boys):
First quartile: left limit of box = 9Third quartile: right limit of box = 17IQR is 17-9 = 8
For females (teen girls):
First quartile: left limit of box = 3Third quartile: right limit of box =15IQR is 15-3 = 12
Thus, there is greater variability in playing time of teen girls (females).
Thus, the gender that shows greater variability in their playing time is females (teen girls).

Girls have a larger interquartile range (IQR), indicating more varied playing times compared to boys.
Let's break down the analysis in detail:
1. Interpretation of Box-and-Whisker Plots:
- Box-and-whisker plots provide a visual representation of the distribution of a dataset. They show the median, quartiles, and range of the data.
2. Understanding Interquartile Range (IQR):
- The interquartile range (IQR) is a measure of statistical dispersion, which is calculated as the difference between the upper quartile (Q3) and the lower quartile (Q1). It represents the spread of the middle 50% of the data.
- A larger IQR indicates greater variability in the dataset.
3. Comparison of IQRs for Boys and Girls:
- For boys:
- Lower quartile (Q1) = 9
- Upper quartile (Q3) = 17
- IQR for boys = Q3 - Q1 = 17 - 9 = 8
- This means that the middle 50% of boys' playing time falls within the range of 8 hours.
- For girls:
- Lower quartile (Q1) = 3
- Upper quartile (Q3) = 15
- IQR for girls = Q3 - Q1 = 15 - 3 = 12
- This indicates that the middle 50% of girls' playing time spans a range of 12 hours.
4. Analysis and Conclusion:
- The interquartile range for girls (12 hours) is larger than that for boys (8 hours).
- Therefore, girls' playing time exhibits greater variability compared to boys'.
- This suggests that there is more diversity in the amount of time girls spend playing video games each week, as indicated by the wider spread of their data points around the median.
5. Reasoning Behind the Conclusion:
- While both groups have the same overall range of possible values (from 0 to 28 hours), the spread of data within the middle 50% (as captured by the IQR) is wider for girls, indicating greater variability in their playing time.
So, based on the analysis of the interquartile ranges, we conclude that girls show greater variability in their playing time compared to boys in this dataset.
It's been so hot out lately that you are thinking of throwing a bucket of water over your brother's head. You have a 2 gallon bucket, 7 quart bucket and an 18 pint bucket. Which bucket holds the most water to splash your brother with? (1 gallon = 8 pints, 1 gallon = 4 quarts, 1 quart = 2 pints)
Answer: The 18 pint bucket.
Step-by-step explanation: If you convert all of the units to gallons, you will find that the 7 quart bucket contains 1.75 gallons and the 18 pint bucket contains 2.25 gallons. Since 2.25 is the greatest amount, the 18 pint bucket contains the most water.

What is the volume of this loaf of bread, assuming that the top part of the end of the loaf is a semi-circle? Show all work.
Answer:
Step-by-step explanation:
We would section the bread into a cuboid at the bottom and a semi cylinder at the top.
Considering the bottom, the formula for determining the volume of a cuboid is expressed as
Volume = length × width × height
Therefore,
Volume = 20 × 11 × 6 = 1320 cm³
Considering the semi cylinder,
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder
h represents the height of the cylinder.
π = 3.14
Looking at the diagram,
Height = 20 cm
Diameter = 11 cm
Radius = diameter/2 = 11/2 = 5.5 cm
Since it is a semi cylinder, then
Volume = 1/2 × 3.14 × 5.5² × 20 = 949.85 cm³
Therefore, volume of this loaf of bread is
1320 + 949.85 = 2269.85 cm³

A watering can contained 512 quarts water. After all the plants were watered, only 4 cups remained. How many cups of water were used to water the plants? 7 cups 18 cups 40 cups 84 cups
Answer:
2044 cups
Step-by-step explanation:
In a quart, there are 4 cups:
1 quart = 4 cups
In 512 quarts, there will be:
4 * 512 cups = 2048 cups
If only 4 cups remained after watering, then the number of cups used to water the plants is:
2048 - 4 = 2044 cups
7-18
18 cups is correct cuz 5/12 in quarts well in the 1st place 4 cups go into a quart then u gatta figure out 4x4=16 and then the 12 at 5/12 add them cuz u got 2 and im pretty sure ull get 7-18

thank me and rate!!! plz thank you :)
Please helppp can someone please help me I am so confused on how to answer these
Answer:
A; D; A; C; C
Step-by-step explanation:
1. S29 means the sum of the first 29 terms. Because it's an arithmetic sequence, the sum of the first x terms is (the first term + xth term)(x)/2
That means the answer to the first question is (7+70)(29)/2 = 1116.5 (A)
2. The sum of the first 18 terms is (56 + 5)(18)/2 = 549 (D)
3. The common difference is 3.5, making the 26th term 87.5. That makes the sum of the first 26 terms (7+94.5)(26)/2 = 1319.5 (A)
4. The question is asking for the sum of the first 28 terms. The first term is 50-4(1) = 46. The 28th term is 50-4(28) = -62. That makes the sum of the first 28 terms (46+(-62))(28)/2 = -224 (C)
5. The first x terms of a geometric sequence is the (first term - (x+1)th term)/(1-(ratio)).
That makes the sum ((1/3)-(729))/(1-3) = -(2186/3)/-2 = 1093/3 = 364 1/3 (C)

Henry want to know how long his patio is . He said the perimeter of his patio is 48 feet . He knows that one side of his patio is 9 feet long . How many feet long are all the sides
Answer:
Step-by-step explanation:
Perimeter = 48 feet
2*(length + width) = 48
2*(9 + width ) = 48
Divide both sides by 2.
9 + width = 48/2
9+width = 24
Subtract 9 from both sides.
9+width - 9 = 24 - 9
Width = 15 feet
Which is not a property of countercurrent multiplication?
Answer:
It is opposed by the vasa recta.
Step-by-step explanation:
Question:
Which of these is not a property of the renal counter-current multiplier?
It is opposed by the vasa recta.
It exploits the structure of the nephron loop.
It depends on active ion transport to function.
It creates a hyperosmotic interstitial fluid in the kidney medulla.
Answer:
The correct option is;
It is opposed by the vasa recta
Step-by-step explanation:
Counter current multiplication is the process whereby energy is used to build osmotic pressure gradient in the kidney such that water is reabsorbed from the exit tubular fluids reducing the volume of produced urine by increasing the urine concentration while the vasa recta capillaries slows blood flow rate so as to keep the osmotic pressure gradient constant enabling water to be reabsorbed thus concentrating the urine in line with counter current multiplication.
An urn contains 8 balls identical in every aspect except color. There is 1 red ball, 2 green balls, and 5 blue balls. You draw two balls from the urn, and you do not replace the first ball before drawing the second. Find the probability that the first ball is blue and the second is green.
Answer:
P(blue and green) = P(blue)*P(green) = (5/8)(2/8) = 10/64
The probability that the first ball is blue and the second is green, with no replacement, is approximately 0.179 or 17.9%.
Explanation:The subject of this question pertains to probability, specifically the concept of dependent events in the realm of combinatorics. The problem involves an urn with 8 balls of different colors. The question asks us to find the probability that a blue ball is drawn first and a green ball second, with no replacement.
Firstly, we calculate the individual probabilities. The probability of drawing a blue ball first is 5/8, because there are 5 blue balls out of a total of 8. Since the blue ball isn't replaced, there are now 7 balls left in the urn, and therefore, the probability of drawing a green ball next is 2/7. To find the combined probability, we multiply the individual probabilities: (5/8) * (2/7) = 10/56 = 0.1786 (rounded). So the probability that the first ball is blue and the second is green is approximately 0.179 or 17.9%.
