Solve using a conversion factor. round to the nearest tenth. david is traveling to the united states for his next weightlifting competition. if he weighs 120.3 kilograms, how much does he weigh in pounds? 1 kg= 2.2 lb

Since 1 kg is = to 2.2 lb just multiply 120.3 kg by 2.2 lb

He weighs approximately 264.66 pounds.

It is approximation because 1 kg does not = 2.2 lb EXACTLY, but for the purpose of this problem I hope this will be good enough :)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
