22.5 miles
You would create a proportion based on the given information, then cross multiply and solve for the number of miles 1 gallon of gas can go.
The area of the square would be 4/25 here is the work:
Area of an 2d shape: length * width
For a square it is 2/5 * 2/5
You multiply the two numbers and you should get 4/25.
If helped mark me the brainiest!!
If the solution is blue-green, this indicates that some copper is still present in the solution and that not all of it has precipitated. Expect it to be too low because you will have less mass.
With very few exceptions, all copper(I) (cuprous) compounds are diamagnetic and colorless. Cu2O, Cu2Cl2, and cuprous sulfide are a few of the significant commercial compounds of copper(I) (Cu2S).
The molar mass of the element copper is determined by looking at its average atomic mass, which is 63.55 AMU on the periodic table. Since it is also our molar mass, we will now put it in a different unit: grams over moles (63.55 gmol). That is copper's molar mass.
If the solution is blue-green, there is still copper in the solution and not all of it has precipitated. Because you will have less bulk, anticipate it to be too low.

Split the number into its whole number component and decimal component.
for the decimal component, 0.2 is the same as 2/10
Find the GCF of both 2 and 10 and that would be 2
divide both the numerator and denominator by the GCF
simplify and you get 1/5
Lastly combine the whole number component with the fraction and your answer would be 1 1/5.
The square root of zero is zero. Because 0 * 0 = 0.
