Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm in diameter. Sand ranges from 0.05 to 2.0 mm.
12.5% of 384 - 16.66% of 66 = √16 + √? + 22
Find the simplified value of the following expression:
62 + 122 × 5 - {272 + 162 - 422}
(65% of 120) = 25% of ? - 22
√10000 × √8100 - (50)² = √(?) + (80)²
√ (573 – 819 + 775) = ? ÷ 3
(2/7)% of 5600 ÷ √ 64 = ?
21% of 400 − 150 = ? − 77
54% of 250 = 6 × 21 + √?
