Divide 54 by 3 to get how many licks are needed for ONE lollipop. Once you figure how many licks are needed for ONE, you can figure out how many it takes for any amount of lollipops.

54 licks / 3 lollipops = 18 licks / 1 lollipop

Divide 36 by 18 and multiply the quotient by 18 to find the number of lollipops 36 licks takes.

36 licks / 18 licks = 2 lollipops (this is your first answer)

Now multiply 18 by 5 like so: 18 * 5 = 90 (this is your second answer)

Step-by-step explanation:

The slack variables make up the difference between the sum of the utilizations and the limit. A separate slack variable is needed for each limit. As with the other variables, its minimum value is zero.

For ( ) ≤ lim constraints, the slack variables are on the left side of the equal sign:

( ) +s ≤ lim.

For ( ) ≥ lim constraints, the slack variables can be on the right side of the equal sign:

( ) = s + lim

The more usual representation in a linear programming matrix is ...

( ) - s = lim

Here, your constraints are "≤", so each equation will have a unique slack variable added to the left side sum.

Factors of 20:1,2,4,5,10,20

Greatest common factor is 4 because it is the highest factor in both sets.

Multiples of 8:8,16,24,32,40,48,56,64,72,80...etc

Multiples of 20:20,40,60,80,100,120,140...etc

Lowest common multiple is 40 because it is the lowest multiple in both sets.

A number being divided by a number would be the same as a number multiplied by the reciprocal of the other number.

Reciprocal: the “flip” of a fraction (ex. the reciprocal of 6/7 is 7/6)

Example:
5/6 / 1/6
= 5/6*6/1
=30/6
=5

We can apply the same to the question 1/5 / 3.

1/5 / 3
=1/5*1/3
=1/15

What is summation?

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.

In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

Given the inventory 2, 4, 2,5,3,1 if we add this inventory to the total then it will come out to be

2+ 4+ 2+5+3+1 =17 hence 17 will be the correct answer.

The Tartars themselves were already becoming an object of curiosity rather than of fear. . . . The frail Latin throne in Constantinople was still standing, but tottering to its fall. The successors of the Crusaders still held the Coast of Syria. . . . The jealousies of the commercial republics of Italy were daily waxing greater. The position of Genoese trade on the coasts of the Aegean was greatly depressed . . . Venice had acquired [power there by expelling] the Greek Emperors. . . . But Genoa was biding her time for an early revenge, and year by year her naval strength and skill were increasing. Both these republics held possessions and establishments in the ports of Syria. . . . Alexandria was still largely frequented in the intervals of war as the great emporium of Indian wares, but the facilities afforded by the Mongol conquerors who now held the whole tract from the Persian Gulf to the shores of the Caspian and of the Black Sea, or nearly so, were beginning to give a great advantage to the caravan routes.Henri Cordiers annotated translation of The Travels of Marco Polo, 1920Source 2"Throughout the twelfth century there were many signs that the European intelligence was recovering courage and leisure, and preparing to take up again the intellectual enterprises of the first Greek scientific enquiries and such speculations as those of the Italian Lucretius. The causes of this revival were many and complex. The suppression of private war, the higher standards of comfort and security that followed the crusades, and the stimulation of mens minds by the experiences of these expeditions were no doubt necessary preliminary conditions. Trade was reviving; cities were recovering ease and safety; the standard of education was arising in the church and spreading among laymen. The thirteenth and fourteenth centuries were a period of growing, independent or quasi-independent cities; Venice, Florence, Genoa, Lisbon, Paris, Bruges, London, Antwerp, Hamburg, Nuremberg, Novgorod, Wisby and Bergen for example. They were all trading cities with many travellers, and where men trade and travel they talk and think. The polemics of the Popes and princes . . . were exciting men to doubt the authority of the church. . . . The Arabs [began] restoring Aristotle to Europe, and . . .
