What is the quotient of 1.232 x 10^8 and 3.85 x 10^5 expressed in scientificnotation?
The quotient of the numbers are:
\(\frac{1.232\times10^8}{3.85\times10^5}\)Recall the quotient of powers property which states that for a real number a and integers x and y, the following is true:
\(\frac{a^x}{a^y}=a^{x-y}\)Divide the numbers (1.232÷3.85) and apply the quotient of powers property to the powers:
\(0.32\times10^{8-5}=0.32\times10^3=3.2\times10^2\)The quotient expressed in scientific notation is:
\(3.2\times10^2\)Refer to the model Q (t) = boe

At an archeological site, scientists uncovered human remains. A sample from a human bone taken from the site showed that 21.2
% of the carbon-14 still remained. How old is the sample? Round to the nearest year. Do not round intermediate calculations.
The sample from the human remains is approximately
years old.
The sample from the human remains is approximately
12,820 years old
Given the model used for radiocarbon dating after a particular period of time "t" expressed according to the formula;
\(Q(t)=b_0e^{-0.0001211t}\)
If a sample from a human bone taken from the site showed that 21.2
% of the carbon-14 still remained, then Q(t) = 21.2
Substitute the given parameters into the formula:
\(Q(t)=b_0e^{-0.0001211t}\\0.212b_0=b_0e^{-0.0001211t}\\0.212 = e^{-0.0001211t}\\ln0.212=lne^{-0.0001211t}\\-1.55117=-0.0001211t\\t=\frac{1.55117}{0.000121}\\t= 12,819.56 years\)
Hence the sample from the human remains is approximately

Answer:
C. $14.95
Step-by-step explanation:
Do $13 times 15 divided by 100 and add that to $13.
Answer:
C. $14.95
Step-by-step explanation:
You can find 10% of your bill by moving the decimal one place to the left. If 26.50 is 100% then 10% is 2.65. Since 20% is 2 times 10%, 20% of the bill is 2.65 + 2.65 = 5.30. Now you know the tip you could leave ranging from poor to good, $2.65 to $5.30. To find 15%, halfway in between, we know 15% is 10% plus 1/2 of 10% (5%). 2.65 plus about 1.30 is 3.95.
Now you have
10% is 2.65 - by moving decimal 1 place left
15% is 3.95 - 10% + 1/2 of 10%
20% is 5.30 - 10% * 2

Jennifer Aniston bought a property for $2,000,000. One year later, she sold it for $2,200,000. Jennifer invested only $1,000,000 of her own money and borrowed the rest interest-free from her friend, Brad Pitt. What was her return on this investment?
This means that she made a 20% return on the money she invested in the property. For every dollar she invested, she earned 20 cents in profit.
To calculate Jennifer Aniston's return on investment (ROI), we can use the formula:
ROI = (Net Profit / Initial Investment) * 100
First, let's calculate the net profit. The net profit is the selling price minus the initial investment:
Net Profit = Selling Price - Initial Investment
Net Profit = $2,200,000 - $2,000,000
Net Profit = $200,000
Next, we calculate the ROI:
ROI = (Net Profit / Initial Investment) * 100
ROI = ($200,000 / $1,000,000) * 100
ROI = 0.2 * 100
ROI = 20%
Jennifer Aniston's return on investment for this property is 20%.

The base of the mountain is 6,500 feet above sea level and AB measures 230 feet across. Given that the measurements for QAP is 20° and QBP is 35°, how far above sea level is peak P ? Express your answer to the nearest foot.
Height above sea level:
Answer:
6610
Step-by-step explanation:
We have tan(X) = opposite/ adjacent
tan(QBP) = PQ/BQ
tan(35) = PQ/BQ ---eq(1)
tan(QAP) = PQ/AQ
tan(20) = \(\frac{PQ}{AB +BQ}\)
\(=\frac{1}{\frac{AB+BQ}{PQ} } \\\\=\frac{1}{\frac{AB}{PQ} +\frac{BQ}{PQ} } \\\\= \frac{1}{\frac{230}{PQ} + tan(35)} \;\;\;(from\;eq(1))\\\\= \frac{1}{\frac{230 + PQ tan(35)}{PQ} } \\\\= \frac{PQ}{230+PQ tan(35)}\)
230*tan(20) + PQ*tan(20)*tan(35) = PQ
⇒ 230 tan(20) = PQ - PQ*tan(20)*tan(35)
⇒ 230 tan(20) = PQ[1 - tan(20)*tan(35)]
\(PQ = \frac{230 tan(20)}{1 - tan(20)tan(35)}\)
\(= \frac{230*0.36}{1 - 0.36*0.7}\\\\= \frac{82.8}{1-0.25} \\\\=\frac{82.8}{0.75} \\\\= 110.4\)
PQ = 110.4
≈110
Height above sea level = 6500 + PQ
6500 + 110

Given that :
Given a drawing produced using a scale :
7 millimeters = 3 meters ; the scale factor for the drawing
Comparing units in millimeter and units on meter
1000 mm = 1 meter
Hence,
3000 mm = 3 meter
Then, we can say;
7 millimeters = 3000 millimeters
7mm : 3000 mm

Figure 2.
Jenny would like to buy a new air conditioner for his home. As seen in Figure 2 above he has
3 types of brands that he can consider. The cash price for Daewoo is RM1,899, Daikin at a
price of RM1,699 and last choice is Mitsubishi at a price of RM1.999. He plans to make 18
monthly instalments, if he pays RM300 as a down payment for the air conditioner that he would
like to buy, find the interest charge for each brand if the interest rate is 4% based on originall
balance if he chooses to buy from Daikin, find the monthly instalment price and instalment
price that he needs to pay.
if Jenny chooses to buy from Daikin, the monthly installment price would be approximately RM98.89, and the total installment price to be paid would be approximately RM1,779.98 (18 monthly installments * RM98.89).
How to determine the monthly instalment price and instalment price that Daikin needs to pay.Calculating the loan amount for each brand by subtracting the down payment from the cash price:
Loan amount for Daewoo = RM1,899 - RM300 = RM1,599
Loan amount for Daikin = RM1,699 - RM300 = RM1,399
Loan amount for Mitsubishi = RM1,999 - RM300 = RM1,699
Calculating the interest charge for each brand:
Interest charge for Daewoo = Loan amount for Daewoo * Interest rate = RM1,599 * 0.04 = RM63.96
Interest charge for Daikin = Loan amount for Daikin * Interest rate = RM1,399 * 0.04 = RM55.96
Interest charge for Mitsubishi = Loan amount for Mitsubishi * Interest rate = RM1,699 * 0.04 = RM67.96
To find the monthly installment price, divide the total amount (cash price + interest charge) by the number of monthly installments:
Monthly installment price for Daewoo = (Cash price of Daewoo + Interest charge for Daewoo) / Number of monthly installments = (RM1,899 + RM63.96) / 18 ≈ RM107.22
Monthly installment price for Daikin = (Cash price of Daikin + Interest charge for Daikin) / Number of monthly installments = (RM1,699 + RM55.96) / 18 ≈ RM98.89
Monthly installment price for Mitsubishi = (Cash price of Mitsubishi + Interest charge for Mitsubishi) / Number of monthly installments = (RM1,999 + RM67.96) / 18 ≈ RM116.72
Therefore, if Jenny chooses to buy from Daikin, the monthly installment price would be approximately RM98.89, and the total installment price to be paid would be approximately RM1,779.98 (18 monthly installments * RM98.89).

THE ONE-EYED JACK MINE INVESTIGATION
The abandoned One-Eyed Jack Mine is about 31 miles off the main road adjacent to the Salmon River Wilderness area. There is only a rutted dirt track left where the access road used to run. It is so steep that when we hiked up it we had to pause every fifty feet or so to catch our breath. It seemed impossible but 3- 5 miles further we found remnants of the old wagons, the mineshaft, and the mill. The gold ore found in this mine was embedded in quartz and prospectors used the mill to grind up the quartz and rinse it with acid in huge shallow vats that were agitated so that the gold would sink to the bottom and the quartz could be washed away.
One arrangement of equipment we noticed included a circular vat about 18 feet in diameter which must have been connected by a huge belt to a smaller circular drive wheel 10 feet in diameter. The distance between the wheel and the vat was 8 feet. The equipment had been partially pre-fabricated then carried up the hill piece by piece to be re-assembled on the spot. Just the belt to connect the vat to the drive wheel would have been a major burden. We wondered how many times they had to carry new ones up to replace it. Calculate the length of belt needed to go around the drive wheel and the vat.
Answer:
The circumference of the drive wheel is 10 feet * 3.14 = 31.4 feet.
The circumference of the vat is 18 feet * 3.14 = 56.52 feet.
The total length of belt needed to go around the drive wheel and the vat is 31.4 + 56.52 = 87.92 feet.

How to calculate for AB for the similar trianglesThe triangles ADE and ABC are similar, this implies that the length AB of the smaller triangle is similar to the length AD of the larger triangle
and the length AC of the smaller triangle is similar to the length AD of the larger triangle
so;
AB/(17 + AB) = 31.5/52.5
52.5AB = 31.5(17 + AB) {cross multiplication}
