Answer:
00:13 mm:ss
Step-by-step explanation:
There are 60 seconds in a minute. This fact can be used to convert the time period(s) to minutes and seconds either before or after you do the subtraction.
<h3>Difference</h3>
It is often convenient to do arithmetic with all of the numbers having the same units. Here, we are given two values in seconds and asked for their difference.
100 s - 87 s = (100 -87) s = 13 s
The difference between the two time periods is 0 minutes and 13 seconds.
<h3>Conversion</h3>
If you like, the numbers can be converted to minutes and seconds before the subtraction. Since there are 60 seconds in a minute, the number of minutes is found by dividing seconds by 60. The remainder is the number of seconds that will be added to the time in minutes:
87 seconds = ⌊87/60⌋ minutes + (87 mod 60) seconds
= 1 minute 27 seconds
100 seconds = ⌊100/60⌋ minutes + (100 mod 60) seconds
= 1 minute 40 seconds
Then the difference is found in the same way we would find a difference involving different variables. (A unit can be treated as though it were a variable.)
(1 min 40 s) -(1 min 27 s) = (1 -1 min) + (40-27 s) = 0 min 13 s
The difference between the two time periods is 0 minutes and 13 seconds.
Answer:
Step-by-step explanation:
First, the profit formula:
PROFIT= TOTAL REVENUE - TOTAL COST
Next, note the points:
- Without Advertisement, Q = 6,000 where Q is quantity supplied
- A formula that gives the total profit P in dollars must take into account that 100cents = 1dollar
- Here, only a dollar is spent on advertisement, hence, Q = 6005
- Advertising expenses have been accounted for and [P = 9cents × Q] where Q is quantity sold.
- 9 cents = 0.09 dollars
TOTAL PROFIT FORMULA = 0.09Q - 500
Answer:
Let's solve for the radius.
r = C / 2π = 88 / (2 * 22/7) = 14
Volume of a cone = 1/3 * πr²h
= 1/3 * 22/7 * 14² * 15
= 3080 cm³
Answer:
5
Step-by-step explanation:
because 5 is used for both numbers and that's why
Answer:
their current cash flow is negative since their expenses are higher than their income:
- monthly net income = $56,000 / 12 = $4,667
- monthly expenses = $1,500 + $3,500 = $5,000
- monthly cash flow = ($333)
they have 3 options:
- Option 1 (which I personally dislike) is that Neil contributes $4,000 less per year to his retirement account in order to balance their net income and expenses. The problem is that once he retires, his income will be much lower.
- Option 2 is that they lower their expenses a little bit, only enough to balance their cash flows.
- Option 3 is that Nancy gets a part time job, maybe a couple of hours per day which will allow her to earn money that can be used to cover some expenses.
Personally I believe that option 2 is the best, but if they definitely cannot lower their monthly expenses, then option 3 would probably fit them.
