LINKS WILL BE REPORTED Jenny drove to the train station and back.
It took three hours longer to go there than
it did to come back. The average speed on
the trip there was 20 mph. The average
speed on the way back was 50 mph. How
many hours did the trip there take?

Round your answer to the nearest hundredth and include your units.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

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.
