In 1995 the USPS approximated that they handled 1.8 x 10^11 pieces of mail. In 2010 the USPS reported that they handled 1.7x10^11 pieces. How many more pieces of mail were handled in 1995 than 2010

Answers

Answer 1
Answer:

Answer:

1 * 10^(10) more pieces of mail were handled in 1995 than in 2010.

Step-by-step explanation:

We are given that in 1995, the USPS approximated that they handled  1.8 * 10^(11) pieces of mail and in 2010, the USPS reported that they handled 1.7 * 10^(11)  pieces.

To find how many more pieces of mail were handled in 1995 than in 2010, we do subtraction of the pieces of mail that were handled in both the years.

Pieces of mail handled in 1995 = 1.8 * 10^(11)

Pieces of mail handled in 2010 = 1.7 * 10^(11)  

As it is clear that more pieces of mail were handled in 1995.

So, Pieces of mail handled in 1995 - Pieces of mail handled in 2010 = (1.8 * 10^(11)) -(1.7 * 10^(11))

=  10^(11) * (1.8 -1.7)

=  10^(11) * 0.1 = 1 * 10^(10)

Hence, 1 * 10^(10) more pieces of mail were handled in 1995 than in 2010.

Option: c is the correct answer.

             c)     70

Step-by-step explanation:

There are two choices in the quality of the item i.e. Cotton or wool.

There are 5 choice of color.

Also there are seven sizes.

Hence, in order to find the total number of items that are needed for a complete assortment we need to use to method of permutation.

i.e. the calculation is:

      2_P_1* 5_P_1* 7_P_1\n\n\n=(2!)/((2-1)!)* (5!)/((5-1)!)* (7!)/((7-1)!)\n\n\n=(2!)/(1!)* (5!)/(4!)* (7!)/(6!)\n\n\n=2* 5* 7\n\n\n=70

                Hence, the answer is:

                        c)   70

The state university reported 1183 cases of flu in their student body for the month of January. If this was a 350% increase above the number of flu cases in the month of December, how many students had flu in December?

Answers

Let us assume the number of students having flu in December = x
Number of students having flu in the month of January = 1183
Percentage increase in the number of people having flu from the month of December to the month of January = 350%
Then we can write the equation as
350x/100 = 1183
350x = 1183 * 100
350x = 118300
x = 118300/350
  = 11830/35
  = 338
So the number of students that were affected by flu in the month of December was 338. This is the easiest way to get to the required answer.

Answer:

338

Step-by-step explanation:

1183/350%

= 338 people
