7 lawns / 4 hours = 1.75 hours per lawn.

1.75 hours per lawn x 21 lawns = 36.75 hours total ( 36 hours and 45 minutes)

¿Cuál es el capital que colocado al 6% quincenal<br> genera en 2 meses un monto de S/. 7200?
Zinaida [17]

Answer:

$27428.57

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

P = Po * (1 + r)^(t)

Where P is the final value, Po is the inicial value, r is the rate of interest, t is the time.

With r = 0.06, t = 4 (The rate is for every 15 days, and the time is 2 months, so we have that 2 months = 4 periods of 15 days) and P = Po + 7200, we have:

Po + 7200 = Po * (1 + 0.06)^4

Po + 7200 = Po * 1.2625

Po * 0.2625 = 7200

Po = 7200 / 0.2625 = $27428.57

In a particular flow network G = (V,E) with integer edge capacities ce, we have already found the maximum s-t flow. However, we
yulyashka [42]

Answer:

Check the explanation

Step-by-step explanation:

1) Algorithm for finding the new optimal flux: 1. Let E' be the edges eh E for which f(e)>O, and let G = (V,E). Find in Gi a path Pi from s to u and a path P_1, from v to t.  

2) [Special case: If P_1, and P_2 have some edge e in common, then Piu[(u,v)}uPx has a directed cycle containing (u,v). In this instance, the flow along this cycle can be reduced by a single unit without any need to change the size of the overall flow. Return the resulting flow.]

3) Reduce flow by one unit along P_1U{(u,v)}UP_2

4) Run Ford-Fulkerson with this sterling flow.

Justification and running time: Say the original flow has see F. Lees ignore the special case (4 After step (3) Of the elgorithuk we have a legal flaw that satisfies the new capacity constraint and has see F-1. Step (4). FOrd-Fueerson, then gives us the optimal flow under the new cePacie co mint. However. we know this flow is at most F, end thus Ford-Fulkerson runs for just one iteration. Since each of the steps is linear, the total running time is linear, that is, O(lVl + lEl).
