Condense the logarithm on the right side:
[tex]3\log_b(p)-\left(2\log_b(t)+\dfrac12\log_b(r)\right)[/tex]
[tex]n\log_b(m)=\log_b(m^n) \implies \log_b(p^3)-\left(\log_b(t^2)+\log_b\left(r^{\frac12}\right)\right)[/tex]
[tex]\log_b(m)+\log(n)=\log_b(mn) \implies \log_b(p^3)-\log_b\left(t^2r^{\frac12}\right)[/tex]
[tex]\log_b(m)-\log(n)=\log_b\left(\dfrac mn\right) \implies \log_b\left(\dfrac{p^3}{t^2r^{\frac12}}\right)[/tex]
So,
[tex]x=\dfrac{p^3}{t^2r^{\frac12}}[/tex]
and [tex]r^{\frac12}=\sqrt{r}[/tex], which makes (4) the correct choice.

Seaver Books, a small book publishing company, wrote off the debt of The Learning Center, and the Academy of Basic Education, both small private schools, after it determined that the schools were facing serious financial difficulty. No notice of the action was sent to the schools; Seaver Books simply stopped sending bills. Nearly a year later, The Learning Center was given a large endowment and a government grant. The resulting publicity brought the school to the attention of Seaver Books, which immediately reinstated the account, and sent a new bill to the school, including interest for the entire time the debt was outstanding. No further action was taken regarding the Academy of Basic Education, which was still operational. Did Seaver Books act ethically in reinstating the debt of one client, and not the other? Explain.
Answer:
Seaver Books and Ethical Practice
Yes. Seaver Books acted ethically in reinstating the debt of The Learning Center and not that of the Academy of Basic Education.
Step-by-step explanation:
Writing off a doubtful debt or account is a determination that is done on a case-by-case basis. When a customer's ability to repay a debt is in doubt, the reasonable act will be to write off the debt from the balance to ensure prudent accounting. When the customer's ability to settle the debt is reassessed to be favorable, the debt can be reinstated accordingly. However, it is better to restate the debt after the customer has settled the account and not before. The good news is that customers are not usually informed that their accounts have been written off as doubtful and need not be informed of the reinstatement.

A cylinder has a base diameter of 20 meters and a height of 5 meters. What is its
volume in cubic meters, to the nearest tenths place?
Volume = PI x r^2 x h
r -s 1/2 the diameter ( 20/2 = 10)
Volume = 3.14 x 10^2 x 5
Volume = 3.14 x 100 x 5
Volume = 3.14 x 500
Volume = 1570 cubic meters
The answer is 1570.8

Takis Tortilla Chips Variety Pack 18 Count
what is the unit rate of the product
Answer:
About 42 cents
Step-by-step explanation:
What we know:
An 18-count variety pack of Taki's chips costs $7.49.
To find the unit rate divide 7.49 by 18, and round to the nearest cent.
7.49/18
Before we do that, what is 749/18?
749/18 = 41 11/18
Divide that by 100 to get your answer
41.61111/100 = 0.4161111, which rounds to 42 cents.

5x-2y=-3 -2x-y=-6 método de reducción suma y resta con procedimiento y respuesta doy corona a quien me ayude en menos de media hora
Answer:
(1, 4)
Step-by-step explanation:
5x-2y=-3 -2x-y=-6 =>
5x-2y=-3
-2x-y=-6 Multiply all three terms by -2: 4x + 2y = 12
Then we have:
5x-2y=-3
4x + 2y = 12
---------------------
9x = 9 and so x = 1. Then, using -2x - y = -6, and substituting 1 for x:
-2(1) - y = -6, or
2 + y = 6, or
y = 4
Then the solution is (1, 4)

Step-by-step explanation:
Suppose that the weather forecast indicates a 10% chance that cold weather will reduce the citrus grower’s profit from $100,000 to $85,000 and a 10% chance that cold weather will reduce the profit to $75,000. Should the grower spend $5000 to protect the citrus fruit against the possible bad weather?
Answer:
We can think in this situation as:
There is 10% (or a probability equal to 0.1) where the citrus grower's profit will be reduced by $15,000
There is 10% (or a probability equal to 0.1) where the citrus grower's profit will be reduced by $25,000
And in the remaining 80% (or a probability equal to 0.8), the profit does not change.
Then the expected value for the total profit can be written as:
EV = $100,000 + ( 0.1*(-$15,000) + 0.1*(-$25,000) + 0.8*$0)
= $96,000
In the case where the citrus grower spends $5000 to protect the fruits against possible bad weather, there is a 100% that is profit will not change, but he must pay $5,000
Then his profit will be:
P = $100,000 - $5,000 = $95,000
So in this case, the profit is $1000 less than the expected profit in the prior case. So the scenario where he does not buy the protection has a larger expected profit, which may mean that is better to not buy it (in a straight mathematical point of view)
One also could think that the values are really close together, so buying the protection does not mean a big change, and increases the security

[tex]\sqrt{18} is between which two whole numbers[/tex]
You need to find which two perfect squares is the sqrt{18} between.
sqrt{16} is a perfect square = 4
sqrt{25} is a perfect square = 5.
We conclude the sqrt{18} lies between the sqrt{16} and sqrt{25}.
