An A grade will be given to students having at least 370 total test points. There is one more test to take before the semester is over. Lesha wants to know what she needs to score on the next test to finish with an A. Write and solve an equation to determine what score she needs to get. Explain your reasoning.

95 points

Step-by-step explanation:

Given

--- expected point

See attachment for points

Required

An inequality to determine the points needed

First, we calculate the points (p) Lesha has already accumulated.

Let the number of points needed be t.

So:

---- i.e. She must score a total of 370

Make t the subject

Substitute 275 for p

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.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
