Hydrometer methods are commonly used to determine soil texture by measuring the particle sizes of soil
(47.981% of 295) + (24.91% of 245) =?
(1440.13 ÷ 31.77) × (√168.69 + 16) - (24.87% of 719.99) = ?
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
13³ + 1.3² + 1.03¹ + 1.003 = ?
?2 = 159.97% of 65.004 + 319.98 ÷ 15.99 - 24
What approximate value should come in place of question mark (?) in the following equations?
39.9% of 1720 + 80.2% of 630 = 89.9% of 1280 + ?
2 (1/4)% of 7999.58 + {49.06% of 898.87} + √143.14 – 19.99% of 1499.63 - (52 - 41) = ?
