Two constructors working together finished building a room in 6 days. How long would it take for each constructor to build the room by himself, if it is known that one of them would require 5 more days than the other?
A can build the room by himself in 10 days, and B can build the room by himself in 15 days.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's call the faster constructor "A" and the slower constructor "B".
We know that B takes 5 more days than A to complete the job.
Let's call the number of days it takes A to build the room "x".
Then the number of days it takes B to build the room is "x+5".
Now,
We also know that if they work together, they can finish the room in 6 days.
Let's call the fraction of the job that A can do in one day "a"
(which means that B can do "a - 1/6" of the job in one day).
We can use the following equation to solve for "a":
1 = (a + a - 1/6) x 6
Simplifying this equation, we get:
1 = (2a - 1/6) x 6
1 = 12a - 1
12a = 2
a = 1/6
So A can do 1/6 of the job in one day.
We can use this information to solve for "x" and "x+5":
1/x + (1/(x+5)) = 1/6
Multiplying both sides by the least common multiple of the denominators (6x (x+5) ), we get:
6 (x+5) + 6x = x (x+5)
Expanding and simplifying, we get:
x² - 7x - 30 = 0
Solving for x using the quadratic formula, we get:
x = 10 or x = -3
Since x has to be a positive number (because it represents the number of days it takes A to build the room), we can ignore the negative solution.
Now,
It takes A 10 days to build the room, and it takes B 15 days to build the room (since B takes 5 more days than A).
Therefore,
A can build the room by himself in 10 days, and B can build the room by himself in 15 days.

Richard and samantha are charting their monthly cash flow. They have some expenses like car repairs and vacations that are not paid each month. How can they account for these non-monthly expenses ?
Final answer:
Richard and Samantha should estimate yearly costs for non-monthly expenses, divide by 12, and save this amount each month, incorporating it as a fixed expense in their budget.
Explanation:
Richard and Samantha can account for non-monthly expenses in their monthly cash flow by setting aside money each month for these irregular expenses. To do this, they should estimate the total cost of these expenses for the year and divide that amount by 12. This will provide the monthly amount they need to save in order to cover costs such as car repairs and vacations without disrupting their budget. Each month, this amount should be treated like a fixed expense and set aside in a savings or separate account, ensuring that funds are available when these expenses occur.
Example:
Car Repairs: Estimated at $600 per year (divide by 12 = $50 per month)
Vacations: Estimated at $1200 per year (divide by 12 = $100 per month)
By including these estimated expenses in their monthly budget, they can create a more accurate and effective budget that accommodates all their financial activities throughout the year.

Kiesha’s quality-control manager told her she must have 97% of her clocks functioning properly. She found a report that said 6 out of 300 clocks tested were not working properly. Kiesha predicts that she will have enough working clocks to please the manager. Which statements are true about Kiesha’s prediction? Check all that apply.
Kiesha’s experimental probability is 1/30
Kiesha will have more than 97% of the products working.
Kiesha will not meet 97% because more than 3% of her clocks will be broken.
Kiesha’s experimental probability is 1/50
When the inventory is 4000 clocks, the prediction is that 3920 clocks will work.
Kiesha will have more than 97% of the products working. The experimental probability is 0.98, not 1/30 or 1/50. When the inventory is 4000 clocks, the prediction is that 3880 clocks will work.
Explanation:To determine if Kiesha will have enough working clocks to please the manager, we need to calculate the percentage of clocks that are functioning properly. We know that 6 out of 300 clocks tested were not working, which means 300 - 6 = 294 clocks were working properly. The percentage of working clocks is (294/300) x 100% = 98%. This means that Kiesha will have more than 97% of the products working, so the statement 'Kiesha will have more than 97% of the products working' is true. The statement 'Kiesha’s experimental probability is 1/30' is false because the experimental probability is calculated by dividing the number of successful outcomes (294) by the total number of trials (300), giving 294/300 = 0.98. The statement 'Kiesha will not meet 97% because more than 3% of her clocks will be broken' is false because the percentage of working clocks is 98%. The statement 'Kiesha’s experimental probability is 1/50' is false because the experimental probability is 0.98, not 1/50. When the inventory is 4000 clocks, the prediction is that 97% of the clocks will work, which is (0.97 x 4000) = 3880 clocks.
Kiesha's experimental probability of a clock not working is 1/50, and with 98% of her clocks working properly, she will exceed her manager's 97% requirement. When scaled to an inventory of 4000 clocks, Kiesha can expect 3920 to be functioning correctly.
Explanation:When analyzing Kiesha's prediction about her clocks, we find that if 6 out of 300 clocks are not functioning, then 294 clocks are working properly. To determine if Kiesha will have enough working clocks to please her manager (who requires 97% to be in working order), we calculate the percentage of working clocks:
294/300 = 0.98 or 98%
This is higher than the manager's requirement of 97%. Therefore, the following statements about Kiesha's prediction are true:
Kiesha's experimental probability of a clock not working is 6/300, which reduces to 1/50, not 1/30.Kiesha will have more than 97% of the products working, as 98% are functioning properly.If Kiesha has an inventory of 4000 clocks and the same proportion of nonfunctioning clocks, she would expect 3920 clocks to work, because 98% of 4000 is 3920.Thus Kiesha's prediction that she will meet the quality requirements is accurate.
harry buys a sofa set that costs$2,000.he pays for it with 12 month installments. how much will he pay each month? if he has to pay5%in interest how much will he pay in all for the sofa set?
Harry's monthly payment for the sofa set is approximately $175, which includes principal and simple interest. The estimated total payment amount after 12 months is $2100.
Harry buys a sofa set that costs $2000 and chooses to pay for it in 12 monthly installments. First, to find out the monthly payment without interest, we divide the total cost by the number of installments. So, $2000 divided by 12 months equals to $166.67.
However, there is an interest of 5% on the outstanding amount. To calculate the total interest on an installment plan, we typically would need to calculate the interest on the reducing balance each month; however, for simplicity, let's assume it's 5% of 2000 for the year, which is $100 (5/100 * $2000). Divided by 12 months, that's about $8.33 in interest per month, giving a total monthly payment of $175 ($166.67 + $8.33).
This simplistic approach gives us a rough estimate, and the actual amount could be slightly different due to the reducing balance method used by most financing options. Assuming the simple interest calculation, Harry will pay $175 per month, and in all, he will pay an estimated total of $2100 ($175 * 12) for the sofa set.
