Jose ran 7.5 miles in 1.5 hours. If Jose runs at the same speed, which proportion can be used to determine the
time (t) it would take Jose to run 12 miles?

2.4 hours to run 12 miles.

Step-by-step explanation:

the proportion is 5:1

for every hour, jose runs 5 miles

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

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.
