The mass of the Earth is about 6,000,000,000,000,000,000,000,000 kg. The mass of a human brain is about 1400 grams SHOW ALL WORK (a) What is the mass of the Earth written in scientific notation?
(b) What is the mess of a human brain in scientific notation?
(c) in comparing the measurements in Parts (a) and (b), what else must be done before a comparison is made

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

5.762159

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9

$25 becasue a 10 increase would make it from 80 to 50
