Asmall town purchases salt by railroad-car loads to be used for melting ice and snow on the roads during the winter. one railroad car holds twelve tons of salt. the amount of salt used in any one storm depends upon the severity and duration of the storm. past experience shows that, of the storms which are serious enough to call for any salt, some will require only one pass of the salt trucks, some will require two passes, and a few will require three passes. each pass (a complete coverage of all of the streets of the town) consumes five tons of salt. also from past experience, it has been estimated that 50 percent of the storms are one-pass storms, 40 percent are two-pass, and 10 percent are three-pass. the initial supply of salt at the beginning of winter is five railroad cars, or sixty tons. construct a markov chain mode to show the consumption of salt over time, where time is measured discretely in the number of storms since the beginning of winter.

fabric (square meters)                   cloaks

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.

step-by-step explanation:

simple you would first have to get   a negative number where as 1 to be multiplied by 24 and then you would have to multiply 6 time 4 and then repeat that process until you reach your term
