1 answer:
Ivanshal [37]3 years ago
3 0

Answer:

Step-by-step explanation:

(-14+\frac{3}{2}b)-(1+\frac{8}{2}b)=-14-1+\frac{3}{2}b-4b

                                   = (-15-\frac{5}{2}b)

(5+2b)+(2b+\frac{3}{2})=(5+\frac{3}{2})+(2b+2b)

                             = (4b+\frac{13}{2})

(\frac{7}{2}b-3)-(8+6b) = (\frac{7}{2}b-6b)-(3+8)

                             = (-\frac{5}{2}b-11)

(-10+b)+(7b-5)=(-10-5)+(b+7b)

                               = (8b-15)

Li Wei has several streams of income, as shown in the table. Some streams are active income and some are passive.
WARRIOR [948]

Based on the streams of income that Li Wei has, we can calculate that he has a total passive income of <u>$3,010.</u>

Passive income refers to income that is made without a person actively involving themselves in the activity generating the income.

In this scenario, the passive income sources are:

  • Stock dividends
  • Business investment interest
  • Royalties from a novel

Total passive income therefore is:

= 530 + 1,080 + 1,400

= $3,010

In conclusion, the total passive income is $3,010.

Volume of sphere = \frac{4}3}\pi r^3

= 4 * 3.14 * 3 * 3 *3 / 3

=  4 * 28.26

= 113.04 cm³
