Acrane able can support a maximum load of 15,000 kg. if a bucket has a mass of2,000 kg and gravel has a mass of 1,500 kg for every cubic meter, how many cubicmeters of gravel can be safely lifted by the crane?

Let

x-------> amount of cubic meters of gravel that can be safely lifted by the crane

we know that

Solve for x

therefore

the answer is

the amount of cubic meters of gravel that can be lifted safely by the crane cannot exceed

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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.
