For example, 20 apples divide into five groups of four apples, meaning that "twenty divided by five is equal to four". This is denoted as 20 / 5 = 4 , or 20 / 5 = 4 . [ 2 ] In the example, 20 is the dividend, 5 is the divisor, and 4 is the quotient.
Evarcha seyun is a small spider with a body divided into two main parts: cephalothorax and an abdomen.The male has a cephalothorax, that is between 2.2 and 2.3 mm (0.09 and 0.09 in) long and 1.6 and 1.7 mm (0.06 and 0.07 in) wide.
In general, if an increase of x percent is followed by a decrease of x percent, and the initial amount was p, the final amount is p (1 + 0.01 x)(1 − 0.01 x) = p (1 − (0.01 x) 2); hence the net change is an overall decrease by x percent of x percent (the square of the original percent change when expressed as a decimal number).
For example, in the 1930s Widmark measured alcohol and blood by mass, and thus reported his concentrations in units of g/kg or mg/g, weight alcohol per weight blood. Blood is denser than water and 1 mL of blood has a mass of approximately 1.055 grams, thus a mass-volume BAC of 1 g/L corresponds to a mass-mass BAC of 0.948 mg/g.
At 10 mg/m 3, nickel is immediately dangerous to life and health. [143] Nickel carbonyl [Ni(CO) 4 ] is an extremely toxic gas. The toxicity of metal carbonyls is a function of both the toxicity of the metal and the off-gassing of carbon monoxide from the carbonyl functional groups; nickel carbonyl is also explosive in air.
Any real number can be written in the form m × 10 ^ n in many ways: for example, 350 can be written as 3.5 × 10 2 or 35 × 10 1 or 350 × 10 0. In normalized scientific notation (called "standard form" in the United Kingdom), the exponent n is chosen so that the absolute value of m remains at least one but less than ten ( 1 ≤ | m | < 10 ).
The leaves are stalked, lanceolate and unlobed; they range from 7.5–32 centimetres (3– 12 + 1 ⁄ 2 inches) in length (smallest near the top) [6] and 2–8 cm (3 ⁄ 4 – 3 + 1 ⁄ 4 in) wide. [5] The flower heads are 3–5 cm (1 + 1 ⁄ 4 –2 in) wide, [5] and usually light blue [6] or lavender; it has also rarely been described as white ...
In mathematics, an ordinary differential equation (ODE) is a differential equation (DE) dependent on only a single independent variable.As with any other DE, its unknown(s) consists of one (or more) function(s) and involves the derivatives of those functions. [1]
