Help? An atom of hydrogen has a mass of about 1.66 x 10-25 grams. An atom of oxygen has a mass of about 2.656 x 10-23 grams. How many times the mass of the hydrogen atom is the mass of the oxygen atom? Give your answer in scientific notation.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

step-by-step explanation:

mark brainliest!

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

the answer would be  

a.

3: 1
