What is the molecular geometry of C2H4? Ethylene, C2H4 has the Lewis Structure: The molecular shape is predicted to be trigonal planar around each carbon atom. This is composed of a σ framework and a π-bond. What is the molecular shape of F2? linearly What is the formal charge of Si in sif6 2? Hexafluorosilicate(2-) […]

How many ways can letters be arranged in prior? The word PRIOR has 5 letters and the letter R repeats twice. So the formula to calculate the answer is: 5!/2! = 5*4*3*2*1 / 2*1 = 120/2 = 60. How many unique ways are there to arrange the letters in the word algebra? 2520 distinct ways […]

Is Tibby pregnant in Sisterhood of the Traveling Pants 2? Soon after moving to Australia, Tibby learns that she is not only pregnant but she is also diagnosed with a terminal disease. She keeps the pregnancy a secret from the sisterhood and her family, as revealing it will also reveal the disease. How does Tibby […]

What are radicals in algebra? A radical, or root, is the mathematical opposite of an exponent, in the same sense that addition is the opposite of subtraction. The smallest radical is the square root, represented with the symbol √. The next radical is the cube root, represented by the symbol ³√. How do you separate […]

Can the area and perimeter of a triangle be the same? Any triangles with the same perimeter and area and with one side the same are congruent. This is no surprise. The area of a triangle is half of the product of the base and the perpendicular height, so given the base and the area, […]

Is 0.03 mg the same as 30 mcg? We define the “best” unit to convert a number as the unit that is the lowest without going lower than 1. For 0.03 milligrams, the best unit to convert to is 30 mcg. How many UG makes a MG? 1000 Is 0.02 mg the same as 20 […]

What is cube root equal to? A cube root is a number that, when cubed, is equal to the given number. It is denoted with an exponent of “1/3”. For example, the cube root of 27 is 271/3 = 3. The cube root of 125/343 is (125/343)1/3 = (1251/3)/(3431/3) = 25/7. What is the cube […]

How do you find the height of a pyramid with a square base? Square Pyramid Formulas derived in terms of side length a and height h: By the pythagorean theorem we know that. s2 = r2 + h. since r = a/2. s2 = (1/4)a2 + h2, and. s = √(h2 + (1/4)a2) This is […]

How did Hypatia contribute to math? Hypatia became a brilliant public speaker and scholar, and she followed her father on the library’s faculty. There she wrote on mathematics and astronomy. She did work on algebraic equations and conic sections. She invented the astrolabe for ship navigation and devices for measuring the density of fluids. What […]

How is math used in transportation? Mathematics is applied in transport system modelling as a basic tool, whether it deals with a network of airlines or a network of railway routes. The optimization or rationalization of already existing transport systems is actually more usual under the present conditions. Why did they switch to common core […]
