A scientist has two acid solutions: Artesia, which is a $70\%$ acid solution, and Borromeo, which is a $20\%$ acid solution. (a) Find the amount of Artesia (in mL) that must be added to $500$ mL of Borromeo in order to produce a $60\%$ acid solution. (b) Find the amount of Artesia and Borromeo (in mL) that can be combined in order to form a $100$ mL solution that is $55\%$ acid. (c) Does there exist a combination of Artesia and Borromeo that is $80\%$ acid?
Answers
Answer:
(a) 2000 mL
(b) 70 mL, 30 mL
(c) No
Step-by-step explanation:
Given that Artesia is a 70% acid solution, and Borromeo is a 20% acid solution.
(a) Let x mL of Artesia is added to 500 mL of Borromeo to produce a 60% acid solution.
So, 70% of x + 20% of 500 = 60% of (x+500)
\(\Rightarrow 0.7 \times x + 0.2 \times 500 = 0.6 \times (x+500) \\\\\ \Rightarrow 0.7 \times x + 0.2 \times 500 = 0.6 \times x+0.6 \times500\\\\ \Rightarrow 0.7 \times x -0.6 \times x= 0.6 \times500- 0.2 \times 500 \\\\ \Rightarrow (0.7-0.6) \times x = (0.6-0.2) \times500\\\\\Rightarrow 0.1 \times x = 0.4 \times500\\\\\)
\(\Rightarrow x = (0.4 \times500)/0.1=2000\) mL.
(b) Let x mL of Artesia and y mL be combined in order to form a 100 mL solution having 55% acid solution.
So, x+y=100\Rightarrow y= 100-x
And, 70% of x + 20% of y = 55% of (100)\\\\
\(\Rightarrow 0.7 \times x + 0.2 \times (100-x) = 0.55 \times 100\\\\\Rightarrow 0.7 \times x + 0.2 \times 100- 0.2 \times x = 0.55 \times 100\\\\\Rightarrow 0.7 \times x -0.2 \times x= 0.55 \times100- 0.2 \times 100 \\\\\Rightarrow (0.7-0.2) \times x = (0.55-0.2) \times100\\\\\Rightarrow 0.5 \times x = 0.35 \times100\\\\\)
\(\Rightarrow x = (0.35 \times100)/0.5=70\) mL.
and y= 100-x= 100-70=30 mL.
(c) Let x mL of Artesia and y mL of Borromeo be combined in order to make 80% acid solution.
And, 70% of x + 20% of y = 80% of (x+y)
\(\Rightarrow 0.7 \times x + 0.2 \times y= 0.8 \times (x+y)\\\\\Rightarrow 0.7 \times x + 0.2 \times y = 0.8 \times x +0.8 \times y\\\\\Rightarrow (0.7-0.8) \times x = (0.8-0.2) \times y\\\\\Rightarrow -0.1 \times x = 0.6 \times y \\\\\Rightarrow \frac {x}{y} = -6 \\\\\)
As x and y are amount of Artesia and Borromeo, so x>0 and y>0
\(\Rightarrow x/y >0\), so the negative value of x/y is not possible.
Ad the negative value of x/y is not so x/y=-6 is not possible, hence, any combination of Artesia and Borromeo that is 80% acid solution is not possible.
A pole 11 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After placing the pole, Rashaad measures the distance from the pole to the stake and from the pole to the tower, as shown in the diagram below. Find the length of the guy wire, to the nearest foot.
Answers
The given question is on trigonometry which requires the application of required function so as to determine the value known. So that the length of the guy wire is 67.0 feet.
Trigonometry is an aspect of mathematics that requires the application of some functions to determine the value of an unknown quantity.
Let the length of the guy wire be represented by l, and the angle that the guy wire makes with the stake be θ. So that applying the appropriate trigonometric function to determine the value of θ, we have:
Tan θ = \(\frac{opposite}{adjacent}\)
= \(\frac{11}{4}\)
Tan θ = 2.75
θ = \(Tan^{-1}\) 2.75
= 70.0169
θ = \(70^{o}\)
Considering triangle formed by the tower and the stake to determine the value of l, we have;
Cos θ = \(\frac{adjacent}{hypotenuse}\)
Cos \(70^{o}\) = \(\frac{23}{l}\)
l = \(\frac{23}{Cos 70^{o} }\)
= \(\frac{23}{0.3420}\)
l = 67.2515
l = 67 feet
The length of the guy wire is 67 feet.

the greek letter used to represent the probability of a type i error is alpha (α). T/F?
Answers
True, the Greek letter used to represent the probability of a Type I error is alpha (α).
In hypothesis testing, a Type I error occurs when the null hypothesis is rejected even though it is true. The alpha level, also known as the significance level, is a pre-determined threshold that indicates the probability of making such an error. By setting an appropriate alpha level, researchers can control the risk of incorrectly rejecting the null hypothesis.
Typical alpha levels used in research are 0.05 or 0.01, indicating a 5% or 1% chance of making a Type I error, respectively. It is crucial to consider the consequences of Type I errors when choosing an alpha level, as it affects the overall reliability and validity of the study.

The balance of a certain loan increases at a rate that is proportional at any time to the balance at that time. The loan balance is $1600 initially, and it is $1920 after one year (365 days). What is the balance of the loan after 90 days?
Answers
By answering the presented question, we may conclude that As a result, proportionality the loan debt after 90 days is roughly $1713.17.
what is proportionality?Proportionate relationships are those that have the same ratio every time. For example, the average number of apples per tree defines how many trees are in an orchard and how many apples are in an apple harvest. Proportional refers to a linear relationship between two numbers or variables in mathematics. When the first quantity doubles, the second quantity doubles as well. When one of the variables decreases to 1/100th of its previous value, the other falls as well. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two remains constant at all levels. The diameter and circumference of a circle serve as an example.
Let B represent the loan balance at any moment t. (t).
k * B d(B(t))/dt (t)
where k is a proportionality constant.
This differential equation may be solved by separating the variables.
k * dt = d(B(t))/B(t).
When both sides are combined, the following results:
B(t) ln(t) = k*t + C
where C is an integration constant.
ln(B(0)) = k*0 + C
ln(1600) = C
So,
\(k*t + ln(B(t)) = ln(B(t)) (1600)\\= k*1 + ln(B(1)) (1600)\\ln(1920) = k + ln (1600)\\k = ln(1920) - ln (1600)\\k = ln(1.2) (1.2)\)
Therefore,
\(ln(B(t)) = ln(1600) * 1.2 * t\\1600 * 1.2t = ln(B(t))\\B(t) = 1600 * 1.2^t\\\)
To calculate the loan balance after 90 days, enter t=90/365:
\(B(90/365) = 1600 * 1.2^(90/365)\\B(90/365) ≈ $1713.17\\\)
As a result, the loan debt after 90 days is roughly $1713.17.

Answers
1.) Proving the absorption law A U (AnB) = A by universal generalization (applied twice).
2.) Proving the associative law An (BnC) = (A n B) n C by membership table.
1.) Let x be an element in An (BnC).
By universal generalization, x is in A or x is in (AnB).
If x is in A, then x is in A U (AnB) by definition of union.
If x is in (AnB), then x is in A and x is in B by definition of intersection.
Since x is in A, x is in A U (AnB) by definition of union.
Therefore, x is in A U (AnB) if and only if x is in A.
By universal generalization, A U (AnB) = A.
2.) Prove the associative law An (BnC) = (A n B) n C by membership table.
Let x be an element in An (BnC).
By definition of intersection, x is in A and x is in (BnC).
By definition of intersection, x is in B and x is in C.
Therefore, x is in A and x is in B and x is in C.
By definition of intersection, x is in (A n B) and x is in C.
By definition of intersection, x is in (A n B) n C.
Therefore, x is in An (BnC) if and only if x is in (A n B) n C.
By membership table, An (BnC) = (A n B) n C.
