Reagan owns a donut shop. Each day, her best selling items are long johns and eclairs (cream filled long johns). She charges $1.60 for each long john and $2.60 for each eclair. Reagan sells 20 to 30 more long johns than eclairs each day. Today, Reagan had $205.40 in revenue from long john and eclair sales.
Model the situation above, and use the model to determine which of the following is a reasonable number of long johns and eclairs that Reagan sold today.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

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.
