Answer:

$20.00  

Step-by-step explanation:

  $2.85 =   3.00  - 0.15

  $5.11   =   5.00 + 0.11

  $7.89 =   8.00 + 0.11      Mentally cancel the 0.11s

  $4.15 =   4.00 + 0.15     Mentally cancel the 0.15s

TOTAL = 20.00 + 0.00

TOTAL = $20.00

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = <em>x</em>

Leg <em>b</em> = 5

Hypotenuse <em>c</em> = 8

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                     x² + 5² = 8²
  2. Isolate <em>x</em> term:                       x² = 8² - 5²
  3. Exponents:                            x² = 64 - 25
  4. Subtract:                               x² = 39
  5. Isolate <em>x</em>:                               x = √39

Please help me with question 20. Thank you.
aleksley [76]

Answer:

B=208.72

Step-by-step explanation:

June 22

July: 22+ 22x (1+10%) = 46.2

Auq: 46.2+ 22 (1+10%) x (1+10%)= 72.82

Sep: 72. 82+ 22 (1+10%)³= 102.102

Oct: 102.102 + 22 x(1+10%)⁴= 134.3122

Nov: 134.3122 + 22×(1+10%)⁵= 169.74342

Dec:169.74342 +22(1×10%)⁶ =208.717762

=208.72
