The amount of mass transported via a pipe over a period of time can be computed as M = t2 t1 Q(t)c(t) dt where M = mass (mg), t1

= the initial time (min), t2 = the final time (min), Q(t) = flow rate (m3 /min), and c(t) = concentration (mg/m3 ). The following functional representations define the temporal variations in flow and concentration: Q(t) = 9 + 5 cos2(0.4t) c(t) = 5e−0.5t + 2e0.15t Determine the mass transported between t1 = 2 and t2 = 8 min with
(a) Romberg integration to a tolerance of 0.1%, obtain an estimate with error O(h6) and calculate εa where appropriate.

b) Determine the mass transported using the three point Gauss-Legendre formula

A bicycle store costs ​$3500 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
vfiekz [6]

Answer: the store needs to sell 50 bicycles each month to break even

Step-by-step explanation:

The average selling price of each bicycle is ​$145.

When we talk of break even, we are referring to the point at which the income being accrued from a business is equal to the total cost of running the business. At this point, their is no profit and there is no loss.

From the example information given,

Total cost of running the business will be

cost of operating the bicycle store + the total amount the store pays per bike.

cost of operating the bicycle store

= ​$3500 per month

The store pays an average of ​$75 per bicycle. If the store buys x bicycles per month, then,

Total the total amount the store pays per bike = 75 × x = 75x

Total cost of running the business per month

= 3500 + 75x - - - - - - -1

The average selling price of each bicycle is ​$145. This means that the selling price for x bicycles will be

145 × x = 145x

Therefore , total income is $145x

To break even,

145x = 3500 + 75x

145x - 75x = 3500

70x = 3500

x = 3500 / 70 = 50

A bracelet costs $39.59 including tax.It is marked down 25 percent.What is the final price of the bracelet after it is marked do
lara31 [8.8K]
If it is marked down 25% and 25% equals 25/100 then you simply take 39.59 x 25/100

39.59 x 25/100 = 9.90

and then you subtract that from the original price 

39.59 - 9.90 = $29.69

after it is marked down, the price is $29.69

The Lakewood Wildcats won 5 out of their first seven games in this year. There are 28 games in the season. About how many games
allochka39001 [22]

Answer:

The total number of matches expected to be won by Lakewood Wildcats in this season  is 20.

Step-by-step explanation:

The number of games played by Lakewood Wildcats = 7

Number of matches won by Lakewood = 5

or, the ratio of Won : Played = 5: 7

Total numbers of games in the season = 28

Let the Lakewood Wildcats win m number of games.

Here, ratio of Won Matches : Played Matches = m : 28

Now, by RATIO OF PROPORTIONALITY:

\frac{5}{7}   = \frac{m}{28}

⇒m = \frac{28 \times 5}{7}  = 20

or, m = 20

Hence, the total number of matches expected to be won by Lakewood Wildcats out of total 28 matches is 20.
