How many milliliters of pure acid should be added to
90 milliliters of 8 % acid solution to produce a solution that is 10%?
Answers
2 milliliters of pure acid should be added to the 90 milliliters of 8% acid solution to produce a solution that is 10% acid.
Let's call the amount of pure acid that needs to be added "x" in milliliters.
First, we need to determine how much acid is present in the 8% solution. 8% of 90 milliliters can be found by multiplying 0.08 by 90, which equals 7.2 milliliters of acid in the 8% solution.
Next, we need to set up an equation based on the fact that we want the resulting solution to be 10% acid. This can be done using the following formula:
(amount of acid in new solution) = (amount of acid in initial solution) + (amount of pure acid added)
We know that the amount of acid in the new solution should be 10% of the total volume, which is the sum of the initial solution and the pure acid added. We can express this as:
0.1(x + 90) = 7.2 + x
Simplifying this equation, we can distribute the 0.1:
0.1x + 9 = 7.2 + x
Subtracting 0.1x from both sides:
9 = 7.2 + 0.9x
Subtracting 7.2 from both sides:
1.8 = 0.9x
Dividing by 0.9:
x = 2

Question #12: There are 15 pieces of fruit in a bowl. 6 of them are pears. What
percentage of the total fruit in the bowl are pears?
Answers
since our denominator in 6/15 is 15, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:
100 ÷ 15 = 6.6666666666667
Once we have that, we can multiple both the numerator and denominator by this multiple:
6 x 6.6666666666667/15 x 6.6666666666667
= 40/100
Now we can see that our fraction is 40/100, which means that 6/15 as a percentage is 40%.
We can also work this out in a simpler way by first converting the fraction 6/15 to a decimal. To do that, we simply divide the numerator by the denominator:
6/15 = 0.4
Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:
0.4 x 100 = 40%
And there you have it! Two different ways to convert 6/15 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
Answer:
40%
Step-by-step explanation:
6/15 = 0.4 = 40%
All these mean the same them, but what we are looking for is a percentage, which is 40%.

What is algebraic expression?An algebraic expression is a mathematical phrase that contains numbers, variables, and operations. It is used to represent a single quantity or value, and can be written in terms of one or more variables.
The rule given is an algebraic expression, x, which is the input, multiplied by 2.85, which is the output. Using this information, we can determine the cost of 10 muffins.
To find the cost of 10 muffins, we can use the algebraic expression given. First, we will multiply 10, the number of muffins, by 2.85, the cost of one muffin. This gives us a total of 28.50. Therefore, the cost of 10 muffins is 28.50.
Using this same rule and process, we can also determine the cost of any number of muffins. For example, if we want to know the cost of 15 muffins, we can simply multiply 15 by 2.85, giving us a total of 42.75.

Answers
The probability P(GH) is 0%.
Since we know that,
Probability denotes the likelihood of something happening. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one.
Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. Probability is defined as the degree to which something is likely to occur.
This is the fundamental probability theory, which is also utilized in probability distribution, in which you will learn about the possible results of a random experiment.
To determine the likelihood of a particular event occurring, we must first determine the total number of alternative possibilities.
Now to find the probability of GH,
We can see that there is no any poit G and H are showing in the given number line,
Therefore,
Favorable outcomes = 0
Since we know that,
Probability = number of favorable outcomes/total number of outcomes
Thus,
⇒ P(GH) = 0/total number of outcomes
Hence,
⇒ P(GH) = 0%

Both the cost of equity and the cost of preferred stock play important roles in determining a company's overall cost of capital and the required return on investment for different types of investors.
To estimate DEF Company's cost of equity, we need to calculate the dividend growth rate and use the dividend discount model (DDM). The cost of preferred stock can be found by dividing the fixed dividend by the current price of the preferred stock.
The calculations will provide the cost of equity and cost of preferred stock as percentages.
To estimate DEF Company's cost of equity, we use the dividend growth model. First, we calculate the expected dividend for the next year, which is given as $0.55 per share.
Then, we calculate the dividend growth rate by taking the expected growth rate of 3.7% and converting it to a decimal (0.037). Using these values, we can apply the dividend discount model:
Cost of Equity = (Dividend / Current Share Price) + Growth Rate
Plugging in the values, we get:
Cost of Equity = ($0.55 / $16) + 0.037
Calculating this expression will give us the estimated cost of equity for DEF Company as a percentage.
To calculate the cost of preferred stock, we divide the fixed dividend per share ($1.8) by the current price per share ($27.6). Then, we multiply the result by 100 to convert it to a percentage.
Cost of Preferred Stock = (Fixed Dividend / Current Price) * 100
By performing this calculation, we can determine DEF Company's cost of preferred stock as a percentage.

The percentage of measurements that are above the 39th percentile is.
Answers
The percentage of measurements that are above the 39th percentile is 61%.
To calculate the percentage of measurements above the 39th percentile, we need to find the complement of the percentile value. The 39th percentile represents the value below which 39% of the measurements fall. Therefore, the complement of the 39th percentile is the percentage of measurements above that value. Since the total percentage adds up to 100%, subtracting 39% from 100% gives us the percentage of measurements above the 39th percentile, which is 61%.
In summary, the percentage of measurements that are above the 39th percentile is 61%. This means that 61% of the measurements are higher than the value corresponding to the 39th percentile.

In general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed.

|4/7 + 2x| ≤ 2/5
By finding the lowest common multiple (LCM) of the absolute value function, we have the following:
|4/7 + 2x(7)/7| ≤ 2/5
|(4 + 2x(7))/7| ≤ 2/5
|(4 + 14x)/7| ≤ 2/5
|(14x + 14)/7| ≤ 2/5

|(2·7x/2 + 2²/2)/7)| ≤ 2/5
|(2(7x + 2²⁻¹)/7)| ≤ 2/5
|2(7x + 2)/7| ≤ 2/5

DifferentiationUsing implicit differentiation, we have ...
3A²·A' = 36π·2V·V'
A' = (36π·2)/3·V/A²·V' = 24πV/A²·V'
A' = 24π·(178.37 in²/(153.24 in²)²·18 in³/s
