Answer:
74
Step-by-step explanation:
12 x 8 = 96
96 - 75% = 24
96 - 24 = 72
72 square inches will have grey paint
Oof, I made a mistake on my previous answer. My tablet is acting weird
54 ft. squared.
So first (my method is), find 3/4 of 8 which is 6. (8/1 * 3/4)
Then, find 3/4 of 12, which is 9. (12/1 * 3/4)
Now to find the area, the method is <em>l </em>*<em> w</em>
Length is 6, width is 9.
6 * 9 = 54 ft. squared.

Explanation: Use FOIL
I think you meant to write
(2 × 10⁶) × 0.00009
First, convert 0.00009 to scientific notation:
0.00009 = 9 × 10 ⁻⁵
Then
(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)
… = (2 × 9) × (10⁶ × 10 ⁻⁵)
… = 18 × 10¹
… = 1.8 × 10²
