You need a 55% alcohol solution. On hand, you have a 550 mL of a 95% alcohol mixture. How much pure water will you need to add to obtain the desired solution?
Answers
Answer:
We need to add 400 ml of pure water to obtain the solution at 55%
Step-by-step explanation:
Concentration
The concentration of a solution measures the amount of solute that has been dissolved in a given amount of solution. The question states the alcohol is the solute and water is the solvent to produce the mix or solution.
The concentration can be calculated with the formula:
[tex]\displaystyle c=\frac{solute}{solute+solvent}*100\%[/tex]
Originally, the mixture was 95% concentrated.
Substituting in the formula:
[tex]\displaystyle 95\%=\frac{solute}{solute+solvent}*100\%[/tex]
We know there were 550 ml of solution (solute+solvent), thus
[tex]solution*0.95=solute=522.5\ ml[/tex]
Now we know there were 522.5 ml of alcohol.
We now need to add x ml of water to have a 55% concentrated solution. Recall that water is solvent, the solute keeps its original value, thus:
[tex]\displaystyle 55\%=\frac{solute}{550+x}*100\%[/tex]
Operating:
[tex]0.55(550+x)=522.5[/tex]
Dividing by 0.55
[tex]550+x=950[/tex]
Thus [tex]x=950-550=400[/tex]
We need to add 400 ml of pure water to obtain the solution at 55%

Find the area and the circumference of a circle with diameter 6 cm.
Use the value 3.14 for it, and do not round your answers. Be sure to include the correct units in your answers.
Answers
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
C≈18.85 cm
A≈28.27 [tex]cm^{2}[/tex]
The area of the circle is approximately 28.27 cm², and the circumference is approximately 18.85 cm.
We have,
Area of a circle: A = πr²
Circumference of a circle: C = 2πr
Radius (r) = Diameter / 2 = 6 cm / 2 = 3 cm
Area of the circle:
A = πr² = π(3 cm)² ≈ 28.27 cm²
Circumference of the circle:
C = 2πr = 2π(3 cm) ≈ 18.85 cm
Therefore,
The area of the circle is approximately 28.27 cm², and the circumference is approximately 18.85 cm.

The ratio of boys to the total number of children on the playground if, There are 24 boys and 16 girls on a playground is 3 / 5.
What is ratio?
It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3. An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
Given:
There are 24 boys and 16 girls on the playground,
Calculate the total number of children as shown below,
The total number of children = 24 + 16 = 40
The ratio of boys to the total number of children is given as,
The ratio of boys to the total number of children = number of boys / total number of children,
The ratio of boys to the total number of children = 24 / 40
The ratio of boys to the total number of children = 3 / 5.

6) A boat traveled 80 miles downstream and back. The trip downstream took 5 hours. The trip back took
10 hours. What is the speed of the boat in still water? What is the speed of the current?
Answers
Answer:
12 mph and 4 mphStep-by-step explanation:
Let the speed of the boat = b and the speed of the current = cEquations to reflect time, time = distance/speed:
Downstream80/(b + c)= 5 ⇒ b - c = 80/5 ⇒ b + c = 16Upstream80/(b - c) = 10 ⇒ b - c = 80/10 ⇒ b - c = 8Sum of the 2 equations above
b + c + b - c = 16 + 82b = 24b = 12c = 16 - 12 = 4So the speed of the boat is 12 mph
The speed of the current is 4 mph

Write an integer to represent a 6 yard loss in football.
Answers
Answer: - 6.
Step-by-step explanation:
The set of integers is the set of the whole numbers. {..., -1, 0, 1, 2, ...}
We want to represent a loss by 6 yards in football.
Because this is a loss, we should use a negative number, then we can use:
-6
This represents the number of yards by which your team losts.
Notice that I did not write the units, this is because:
-6 yards is a measure, furthermore can be "an integer number of yards"
-6 is an integer.
find the percent change from 50 to 22
Answers
Answer:
28
Step-by-step explanation:
50 - 22 = 28
Answer:
56% decrease or -56.00%
Step-by-step explanation:
1) Find the difference between 50 and 22 as a number.
2) Divide the result from Step 1 by the starting number 50.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 50 to 22, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 50, and Y is the ending number 22 that it changed to When we enter these numbers into the formula, we get:
((22-50)/50)*100 = -56.00%

You need to arrange 10 of your favorite books on a small shelf. How many different ways can you arrange the books, assyming that the ordwr of the books make a differe
Answers
Answer:
You can arrange the books 3,628,800 different ways.
Step-by-step explanation:
You can imagine that the shelf has 10 "slots" where you can place a book. Each slot can take 1 of the 10 books. However, after you have placed 1 book, there are only 9 possible books to place. After 2 have been placed, there are only 8 possible.
Going left-to-right, the first slot has 10 available books.
Total combinations: 10
The 2nd slot has 9 available books.
Total combinations: 10 * 9
The 3rd slot has 8 available books.
Total combinations: 10 * 9 * 8
This continues for all 10 slots.
Eventually, for slot 10, there is only 1 book possible.
Total combinations: 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1
Multiply all numbers between 10 and 1 with each other is also known as "10 factorial" or "10!"
Thus, the total number of combinations is:
[tex]10! = 10*9*8*7*6*5*4*3*2*1 = 3628800[/tex]
Answer: You can arrange the books 3,628,800 different ways.

Step-by-step explanation:
From the picture attached,
Multiplication of two fractions gives the result as [tex]\frac{1}{10}[/tex].
This shows that the denominator of the fractions when multiplied with each other results a number that will be the multiple of 10.
Therefore, from the given numbers,
5 × 6 = 30
Rest two numbers be placed as the numerator of the fractions.
[tex]\frac{1}{5}\times \frac{3}{6}=\frac{3}{30}[/tex]
[tex]=\frac{1}{10}[/tex]
Therefore, [tex]\frac{1}{5}\times \frac{3}{6}=\frac{1}{10}[/tex] will be the answer.

4x = 8
x = 2
When x=2 f(x)=g(x)

Suppose you are interested in how participants behave in different color conditions. You select 30 participants and assign them to one of three rooms. The rooms differ only with respect to the color of the walls. One room is white, one is pale blue, and a third is bright red. Each participant is served a meal of a hamburger and french fries, and you then measure how long it takes them to finish eating. What would be the independent variable in this study
Answers
The answer is the color of the room
Explanation:
In this study, the color of the room is the factor or variable that is modified by the researcher. Also, it is expected the color of the room affects participants' behavior but not the opposite. This shows the color of the room is an independent variable because this factor is not affected by other variables, and it modifies the dependent variable (behavior). Moreover, in studies, the independent variable is always the one that is changed by the researcher.
