Determine the unit rate of the following.
240 hours of homework in 8 weeks.

Step-by-step explanation:

In order to solve this exercise it is important to remember that a "Rate" is defined as a ratio that compares two different but related quantities.

Then, "Unit rate" tell us how many units of the first  quantity corresponds to one unit of the second quantity. Therefore, the second quantity is equal to 1.

According to the information given in the exercise, you know that the number of hours of homework in 8 weeks is 240 hours.

Then, in order to determine the Unit rate (the number of hours per week), you need to divide 240 hours by 8 weeks.

Through the procedure explained above, you get the that the number of hours per week is the following:

(Notice that it is )

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
