A map is created of Maricopa County with a scale factor of 1 inch = 2.5 miles. The distance between Phoenix and Fountain Hills is 2.92 inches on the map. Determine the actual distance between the two cities.

The actual distance between Phoenix and Fountain Hills is 7.3 miles

Step-by-step explanation:

We note that the scale factor gives the ratio of the map reading to the actual distance reading

The scale factor of the map is 1 inch = 2.5 miles

The distance between Phoenix and Fountain Hills = 2.92 inches on the map

Let the actual distance between Phoenix and Fountain Hills = D, we have;

D/(2.92 inches) = 2.5 miles/inch

Therefore;

D = 2.92 inches ×  2.5 miles/inch = 7.3 miles

D = 7.3 miles

The actual distance between Phoenix and Fountain Hills = D = 7.3 miles.

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.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
