1. to calculate discretionary money, you
a. calculate the difference between your gross pay and net income
b. calculate the difference between your net income and fixed expenses
c. calculate the difference between your gross pay and fixed expenses
d. calculate the sum of your net income and fixed expenses

option B

Step-by-step explanation:

To calculate discretionary money, you calculate the difference between your net income and fixed expenses.

Discretionary money is the left with an individual after paying taxes, personal expenses such food, shelter and clothing, etc. The left money can be used for saving, investing, etc. it purely depends upon individual discretion.

hence Option B is correct

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
