Question 2
if a calculator is sold for $16.15, then the revenue in dollars, r, generated by this item is
given by the formula r=16 15q, where q represents the number of calculators sold. use
the formula to determine the revenue generated by this item if 28 calculators are sold

Revenue = $452.2

Step-by-step explanation:

Given,

The selling price of a calculator, P = $16.15

The given equation is R = 16.15*q

We know that, Revenue = Price*Quantity

If the selling numbers of calculators is 28,

according to the question,

Revenue = $16.15*28

Revenue = $452.2

That is an example of a linear equation. In this equation, if we increase the quantity sold, the revenue will increase automatically.

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.
