Answer:
Benefits. Businesses use consumer spending data in their supply and demand economic calculations. Supply and demand helps businesses produce goods or services at the most favorable consumer price points. ... Consumer spending helps companies determine which products have the most value in the economic marketplace.

E
Answer:
0.86 g/mL
Explanation:
In order to solve the problem, you have to know the formula for "Density." Density refers to<em> </em><em>"mass per unit volume." </em><em>It's formula is:</em>
- <em>Density (ρ) = </em>
<em />
Next, we have to convert the units of measurement in accordance to what is being asked in the problem. It is asking for "g/mL," which means we have to convert 1.25 quarts<em> (qt.) </em>to mL and 2.25 pounds<em> (lbs.)</em> to grams.
Let's solve.
1.25 qt. x 
=<em> 1,182.94 mL</em>
2.25 pounds x 
= <em>1,020.58 grams</em>
Now that we converted them to their appropriate units of measurement, we can now solve for density.
- <em>ρ = </em><em />
- <em>ρ = </em>
<em />
<em>The density of the motor oil is 0.86 g/mL</em>
Answer:
It only has 7 valence electrons because there are seven electrons in the highest orbital.
Explanation:
In this question, the patient needs to be given exactly <span>1000ml </span>of a 15.0%. The content of the glucose should be:
weight= volume * density* concentration
1000ml * 1mg/ml *15%= 150mg.
The stock solution is 35%, then the amount needed in ml would be:
weight= volume * density* concentration
150mg= volume * 1mg/ml *35%
volume= 150/35%= 3000/7= 428.5ml
Part 1: Potassium, and Rubidium.Part 2: Calcium has 20 protons and 20 electrons because the atomic number for calcium is 20 and that determines how many protons there are and in an atom, the number of protons is the same number of electrons. Calcium has about 20 neutrons. I got the number of Neutrons by subtracting the mass number(40.078) and the atomic number(20), I got 20.078. Round to the nearest whole number because you cannot have half or partial neutron. So, Calcium has 20 protons, 20 electrons, and 20 neutrons,
Hope this helps and please mark as brainliest!
