if on January 1st 2015 you decided to read 1001 Nights over the next 1001 Nights on which date would you finally finish

Answers

Well, one year is 365 days, and a leap year is every 4 years with an extra day, making leap years 366 days. 2016 is the nearest leap year. So, We take 365 from 1001 to get 636 days. Now it is January 1st 2016. So, subtract 366 from 636 to get 270 days. It is now January 1st 2017. There are 31 days in December, 30 in November, and 31 in October. Adding these together, you get 92. Subtracting 92 from 365, we get 273. So three days before October 1st is when you end. There are 30 days in September, so taking three away gives us the night of the 27th of September, 2017. So, the date you finish, if staying on a schedule of reading a bit each night, would be the night of September 27th, 2017, which is a Wednesday.

Each sales associate at an electronics store has a choice of the two salary options shown below:-$115 per week plus 9.5% commission on the associate's total sales
-$450 per week with no commission

The average of the total sales amount for each associate last year was $125,000. Based on this average, what is the difference between the two salary options each year? (52 weeks = 1 year) (10 POINTS)

Answers

$450 x 52 weeks = $23400

$115 x 52 weeks = $5980

125000 x 0.095 = 11875

11875 + 5980 = 17855

23400 - 17855 = 5545

The difference is $5545

Part B: Solve 2a − 5d = 30 for d. Show your work. (6 points)

Answers

Given Equation: 2a − 5d = 30 

Solution:

2a - 5d = 30

-5d = 30 -2a

d = ( 30 - 2a )/ (-5)

  =  -6 + (2a/5) 

  = (2a/5) - 6

Morgan measures the capacity of a juice glass to be 12 fluid ounces. If she uses the glass to drink 4 glasses of water throughout the day, how many pints of water does morgan drink?

Answers

So,

Morgan drank 4 glasses of water out of a juice glass that contains 12 fluid ounces.  To find how many pints Morgan drinks, we need to multiply the number of glasses by the number of fluid ounces, convert from fl. oz. to cups, and convert from cups to pints.

4 * 12 = 48 fl. oz.

8 fl. oz. = 1 cup
48 fl. oz. = 6 cups

2 c. = 1 pt.
6 c. = 3 pt.

Morgan drink 3 pints of water.
approximately 3 liquid pints. (3.00005)
