How do I do these questions?
yan [13]

Step-by-step explanation:

The imaginary part of the number is where i is being multiplied by a constant. The real part is where there is no i present. I'll do a few examples.

26. The real part is 0, since there are no terms that don't have i. The imaginary part is 8i, since i is being multiplied by 8.

27. The real part is 7, since there is no i. The imaginary part is 3i, since i is being multiplied by 3.

31. The real part is 52, since there is no i. The imaginary part is 0i, since i is being multiplied by 0. You don't see the i because zero times i is zero.

Jennifer Kent receives 24 paychecks each year. Each check is for $863.50 before deductions. What is Jennifer's weekly salary?
Ymorist [56]

There are 52 weeks in a year.


First multiply the amount of her check by the number of checks she gets:

863.50 x 24 = 20,724


Now divide that amount by 52 weeks:

20724 / 52 = $398.54 per week.

Boxes of sticky finger s popsicles are 4.50. The supermarket is offering a 30%off coupon. What is the price with the coupon?
natali 33 [55]
If it is 30% off, then ur actually paying 70%
70% of 4.50....turn percent to decimal...." of " means multiply
0.70(4.50) = 3.15 <==

another way...
4.50 - 0.30(4.50) = 4.50 - 1.35 = 3.15 <==

either way, u will get the same answer :)
