Steve takes 6 hours to get the yard work done by himself. If Bill works alone, it takes him 10 hours. How long would it take them working together to do all of the yard work?
Answer:
In 3 hour 45 minutes Both working together do all of yard work.
Step-by-step explanation:
Time taken by Steve to do yard work = 6 hours
Work Done by Steve in a hour = [tex]\frac{1}{6}[/tex]
Time taken by Bill to do yard work = 10 hours
Work Done by Steve in a hour = [tex]\frac{1}{10}[/tex]
Work done by both in a hour = [tex]\frac{1}{6}+\frac{1}{10}=\frac{5+3}{30}=\frac{8}{30}=\frac{4}{15}[/tex]
Time taken by by both working together = [tex]\frac{1}{\frac{4}{15}}=\frac{15}{4}=3.75=3\,hour\,45\,minutes[/tex]
Therefore, In 3 hour 45 minutes Both working together do all of yard work.

If f(x) = 9x + 1, find f–1 (f (3))
Answer:
The value of [tex]f^{-1}(f(3))[/tex] is 3.
Step-by-step explanation:
Here, the given function is,
[tex]f(x)=9x+1-----(1)[/tex]
For finding [tex]f^{-1}(f(3))[/tex] we have to find out the inverse of f(x),
The steps are as follows,
Step 1 : Replace f(x) by y,
[tex]y=9x+1[/tex]
Step 2 : Switch x and y,
[tex]x=9y+1[/tex]
Step 3 : Isolate y in the left side,
[tex]-9y=1-x[/tex]
[tex]\implies y = \frac{x-1}{9}[/tex]
Step 4 : replace y by [tex]f^{-1}(x)[/tex],
[tex]f^{-1}(x)=\frac{x-1}{9}------(2)[/tex]
Now,
[tex]f^{-1}(f(3))=f^{-1}(9\times 3+1)[/tex] ( From equation (1) )
[tex]=f^{-1}(28)[/tex]
[tex]=\frac{28-1}{9}[/tex] ( From equation (2) )
[tex]=\frac{27}{9}[/tex]
[tex]=3[/tex]

The delivery van arrives at an office every day between 3 PM and 5 PM. The office doors were locked between 3:15 PM and 3:35 PM. What is the probability that the doors were unlocked when the delivery van arrived?
A. 5/6
B. 5/12
C. 1/3
D. 1/6
The probability that the office doors were unlocked when the delivery van arrived is 5/6. The correct option is A. 5/6.
To determine the probability that the office doors were unlocked when the delivery van arrived, we first need to understand the time intervals:
The delivery van arrives between 3 PM and 5 PM, which is a total of 2 hours or 120 minutes. The office doors were locked between 3:15 PM and 3:35 PM, which is a total of 20 minutes.The total available time for the delivery van to arrive is 120 minutes, out of which the doors were locked for 20 minutes.
Now, we'll calculate the probability that the doors were unlocked:Unlocked time = Total time - Locked time = 120 minutes - 20 minutes = 100 minutesProbability = Unlocked Time / Total TimeProbability = 100 / 120 = 5/6.Car A began a journey from a point at 9 am, traveling at 30 mph. At 10 am car B started traveling from the same point at 40 mph in the same direction as car A. At what time will car B pass car A?

27
Answer:
The answer is 27
Step-by-step explanation:
The third term of the given geometric sequence is 27, calculated by using the geometric sequence formula with the first term of 3 and a common ratio of 3.
Explanation:The third term of a sequence that has a first term of 3 and a common ratio of 3 is calculated using the formula for geometric sequences, which is a_n = a_1 \(\cdot\) r^{(n-1)}, where a_n is the nth term, a_1 is the first term, and r is the common ratio. To find the third term (when n=3), we substitute the given values into the formula to get: 3 \(\cdot\) 3^{(3-1)}.
Calculating that gives us 3 \(\cdot\) 3², which equals 3 \(\cdot\) 9, so the third term is 27.

Silver scooter finds that it costs $300 to produce each scooter and the fixed costs are $750. The price is given by p=900-x, where p is the price in dollars at which exactly x scooters will be sold. Find the quantity of scooters that the company should produce and the price it should charge to maximize profit. Find the maximum profit. ...?
To maximize profit, the company should produce 300 scooters and charge a price of $600. The maximum profit is $88,500.
Explanation:The company should produce a quantity of scooters that maximizes profit. To find this quantity, we need to find the point where marginal revenue (MR) equals marginal cost (MC). In this case, MR is given by the derivative of the price equation, which is -1. So, we set -1 equal to the derivative of the cost equation and solve for x:
-1 = 300
This gives us x = 300. So, the company should produce 300 scooters to maximize profit. To find the price, we substitute this value of x into the price equation:
p = 900 - 300 = 600
Therefore, the company should produce 300 scooters and charge a price of $600 to maximize profit. The maximum profit can be calculated by subtracting the total cost from the total revenue. The total revenue is given by the price multiplied by the quantity sold, and the total cost is given by the fixed costs plus the cost per unit multiplied by the quantity sold. Using the given values, we have:
Total revenue = 600 * 300 = $180,000
Total cost = 750 + 300 * 300 = $91,500
Maximum profit = Total revenue - Total cost = $180,000 - $91,500 = $88,500

If the public debt of a country in 2009 was $12,752,000,000,000 and the budget for 2010 was in deficit by $201,645,000,000, what was the public debt in 2007?
Answer:
$ 12953645000000
Step-by-step explanation:
To find the public debt in 2007, subtract the deficit for 2008 from the public debt in 2007.
Explanation:To calculate the public debt in 2007, we need to work backwards from the given information. We know that the public debt in 2009 was $12,752,000,000,000 and the budget for 2010 was in deficit by $201,645,000,000. We can assume that the deficit for each year is equal to the change in the public debt from the previous year. So, we subtract the deficit for 2010 from the public debt in 2009 to find the public debt in 2010. Then, we subtract the deficit for 2009 from the public debt in 2010 to find the public debt in 2008. Continuing this process, we can subtract the deficit for 2008 from the public debt in 2007 to find the answer.
To summarize, we can find the public debt in 2007 by subtracting the deficit for 2008 from the public debt in 2007.

Shannon manages a crew of painters. a homeowner paid the crew $560 to paint a garage. shannon received $164 of the money, and she shared the rest equally among the other three members of her crew. how much money did each of the three crew members receive for the job?
Each of the three crew members received $132 for the job.
Step-by-step explanation:Total amount paid to Shannon = $560
Share received by Shannon = $164
So, money left for other 3 members = [tex]560-164=396[/tex] dollars
As Shannon shared the left money ($396) equally among the other three members of her crew, so each person got :
[tex]\frac{396}{3}[/tex] = $132
Therefore, each of the three crew members received $132 for the job.

A car salesman sells cars with prices ranging from $5,000 to $45,000. The histogram shows the distribution of the numbers of cars he expects to sell over the next 10 years. What is the median of the car price range?
The correct answer is: C. The median will shift to the right.
Adding 200 cars with prices less than $5,000 will increase the number of cars being sold overall but will not significantly affect the upper end of the price range. Since the added cars are all below $5,000, they will contribute to the left side of the distribution.
As a result, the median, which represents the middle value of the distribution, will shift to the right, reflecting the increase in the number of lower-priced cars being sold.
The mean may or may not be affected, depending on the relative prices of the additional cars compared to the existing distribution, but it's not guaranteed to shift in any particular direction.
Similarly, the median and mean do not necessarily have to be the same, so option B is not accurate. Thus, option C is the most appropriate choice.
Complete question:

Yolanda is finding 23,567-12,458. She added 2 to 12,458 before subtracting. Then she added it in again after she subtracted. Is her method correct? Explain.
Yolanda's method is incorrect because she should have subtracted the 2 she added before subtracting, not added it. Adding it before and after the subtraction alters the original values and results in an inaccurate subtraction.
Explanation:No, Yolanda's method is not correct. If you add a value to a number before subtracting, you have to subtract that same value after the subtraction, not add it again. This is because the addition of 2 alters the original value of 12,458, making it 12,460, and thus changes the result of the subtraction. However, by adding 2 again after subtracting, Yolanda incorrectly compensates for the initial addition. The correct approach would have been to subtract 2 after the subtraction, returning 12,458 to its original value and ensuring the accuracy of the subtraction.

The number of people that belong to a certain social website is 412 and growing at a rate of 5% every month. How many members will there be in 9 months? Enter your answer in the box. Round to the nearest whole number.
Answer:639
Step-by-step explanation:
The equation for exponential growth is: initial amount( 1 + rate in decimal form)^time
So we put in our numbers and it is: 412( 1 + 0.5) ^ 9 = 639 (rounded)
I know this is late but I hope I helped anyone who's looking for an explanation now!
To estimate the number of members on a social website after 9 months with a 5% monthly growth rate, use the formula for exponential growth. After calculations, there will be approximately 639 members after 9 months.
Explanation:The question is related to exponential growth, which is a topic in mathematics. To calculate the number of members on a social website after 9 months given a monthly growth rate of 5%, you can use the formula for exponential growth:
Future Value = Present Value * (1 + growth rate)^number of periods
In this case, the Present Value is 412 members, the growth rate is 5%, or 0.05 when expressed as a decimal, and the number of periods is 9 months. Plugging these values into the formula gives:
Future Value = 412 * (1 + 0.05)^9
Calculating this gives:
Future Value ≈ 412 * (1.05)^9 ≈ 412 * 1.55132822 ≈ 639.25
After rounding to the nearest whole number, there will be approximately 639 members on the social website after 9 months.
