2.1 x 10 to the power of 4.
10x10= 100 x 10= 1,000 x 10= 10,000
10,000 x 2.1= 21,000

A fort had enough food for 80 soldiers for 60 days .How long would the food last if 20 more soliders join after 15 days ?

andrey2020 [161]

Answer:

The food would last 51 days

Step-by-step explanation:

After 15 days are over, you could say that the 16th day would be as follows -

80 soldiers, food finished in 60 - 15 = 45 days.

If 20 more soldiers arrive, there would be a total of 100 soldiers, so if 80 soldiers can finish their food in 45 days - 1 soldier can finish = 45 * 80. Respectively, 100 soldiers can consume their food in ( 45 * 80 ) / 100 = 36 days.

As 15 days are already over, adding 36 more days = 51 days

The food would last 51 days if 20 more soldiers join after 15 days

There are several possible ways to answer this question, but I hope that explanation helps!

An anthropology article presents a hypothetical situation that could be described by a linear programming model. Suppose a popul

solong [7]

Answer:

The minimum labor = 270 hours and it is obtained when 0 units of plants and 18 animals are collected.

Step-by-step explanation:

We assume that x should represent the number of units of plants

Also y to represent the number of animals.

So, minimze (z) = 30 x + 15 y

Subject to:

30 x + 20 y ≥ 360

10 x + 25 y ≥ 300

y ≤ 8

0 ≤ x ≤ 25

0 ≤ y ≤ 25

Changing the above linear inequalities into linear equation; we have:

30 x + 20 y = 360

10 x + 25 y = 300

y = 8

The graph for the above discussion can be located in the attached diagrammatic expression below:

NOW, the corner points (0,18),(0,25),(25,25), and (25,8) can be calculated from the graph. From the diagram, the corner point $[\frac{60}{11} , \frac{108}{11} ]$ can be found by solving the system.
