andriy [413]

To determine the number of days that an employee work in a week, we simply use dimensional analysis and multiplying the number of works per week with the number of weeks in total for a year. That is,
employee works = (5 days per week)(49 weeks per year)
=245 days

In each of the following pairs of numbers, how much larger is the first number than the second?

lapo4ka [179]

Answer: a. 154 is larger than 27 by 127.

b. 25 is larger than 12 by 13.

c.135 is larger than 127 by 8.

d.46 is larger than 24 by 22.

Step-by-step explanation:

Subtract second number from the first number.

a. 154 and 27

Difference= $154-27=127$

Hence, 154 is larger than 27 by 127.

b. 25 and 12

Difference= $25-12=13$

Hence, 25 is larger than 12 by 13.

c. 135 and 127

Difference= $135-127=8$

Hence, 135 is larger than 127 by 8.

d. 46 and 24

Difference= $46-24=22$

Hence, 46 is larger than 24 by 22.

Can someone please explain?

GREYUIT [131]

The function y = x, called the "identity" or "ramp" function, is a basic function that you'll need to add to your math vocabulary. Since the " x " here seems to have no exponent, fix that by thinking "x^1," or "x to the first power," or "y=x is a linear function."

The graph of y=x always goes thru the origin. It begins in the 3rd quadrant and ends in the 1st, and appears as a straight line with slope of m = rise / run = 1/1 = 1.
