1. a scuba diver is swimming around a coral reef 12.25 meters below sea level. he ascends (swims upward) 8.5 meters to look at a sea turtle. write an expression to describe the situation. what is his new position? explain how you wrote the expression and solved the problem.

2. a scuba diver is 9 1/2 feet below sea level viewing some tropical fish. she descends (swims downward) 10 1/2 feet to get a closer look at a manta ray swimming on the sea bottom. write an expression to describe the situation. what is her new position? explain how you wrote the expression and solved the problem.

His new position is 3.75 meters 12.25 - 8.5 = 3.75.

Her new position is 20 ft 9 1/2 + 10 1/2 = 20.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

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.
