Answer:

Working memory

Step-by-step explanation:

Working memory is a system the brain uses  for temporarily storing and managing the information required to carry out complex cognitive tasks. The central executive part of the prefrontal cortex at the front of the brain is responsible for working memory. It serves as a temporary store for short-term memory, where information is kept available while it is needed for current reasoning processes.

So to be successful in holding the number 2.82 in my head while sorting, one must keep the information maintained in short-term storage by using one's working memory.

A box of cereal states that there are 75 calories in a 34-cup serving. What is the unit rate for calories per cup? How many calo
xeze [42]
The unit rate is how many calories are in 1 cup of cereal.
Set up a proportion:
\frac{75 cal}{3/4 cup} = \frac{X cal}{1 cup}
Cross multiply and solve:
\frac{3}{4} X = 75\\ 3X=300\\X=100
There are 100 calories per cup of cereal.

To get the calories in 4 cups of cereal, simply multiply the unit rate of 100cals/cup by 4.
100*4=400
There are 400 calories in 4 cups of cereal.
