Answer: 36

Step-by-step explanation:

From the question, we are informed that for every 4 silver cars that are sold, 6 red cards are also sold.

When there are 90 cars sold in a month, the number of silver cars that were sold would be:

= [4 / (4 + 6)] × 90

= 4/10 × 90

= 4 × 9

= 36 silver cars

The solar cells I have supply 34 watts per square meter. 100 square meters will supply 100 x 34 = 3400 watts which is 3.4 kilowa
777dan777 [17]

Answer:

<u>The correct answer is 58.82 square meters of solar panels will be needed to supply 2 kilowatts</u>

Step-by-step explanation:

Solar cell energy supply = 34 watts per square meter

Therefore, 100 square meters will supply 3400 watts which is 3.4 kilowatts.

How many square meters of solar panels would you need to 2 kilowatts?

Total energy = 2 kilowatts = 2,000 watts

Number of square meters = Total energy/Solar cell energy supply

Number of square meters = 2,000/34

<u>Number of square meters = 58.82</u>

<u>It will be necessary 38.82 square meters of solar panels to supply 2 kilowatts</u>

Write a short paragraph composes at least 10 sentences<br>discussing factors affecting solubility​
kumpel [21]

Answer:

Step-by-step explanation:

Solubility can be defined as the ability of a solute (could be solid, liquid or gas) to dissolve in a solvent in order to produce a solution. There are several factors affecting solubility which includes (basically four) temperature, polarity, surface area of solute particles and pressure of gases. Generally, an increase in temperature leads to an increase in the solubility of a solute in a solvent. This is because an increase in temperature will increase the average kinetic energy of molecules in the solution which leads to increase interaction between the solute and solvent particles. There is a general saying of "like dissolve like" when discussing polarity. For example, organic solvents are used to dissolve organic solutes (just as petrol is used to wash grease off hands and surfaces). Hence, when the solute and solvent have the same polarity, solubility occurs easily, otherwise solubility may be difficult or may not even occur. A reduced/smaller surface area of the solute leads to an increase in solubility as this makes it easy for the solute particles to interact easily with the solvent. In gases, an increase in pressure increases the interaction between the gaseous molecules of the solute and the solvent, thus leading to an increased solubility. Pressure does not affect solubility in solids and rarely in liquids.

Mike is making a mixture for an upcoming camp trip. He makes the mixture by combining 1/3 of a cup of cashews and 1/4 cups of al
kozerog [31]

Answer:

16 cups of cashews

12 cups of almonds

Step-by-step explanation:

Let's say x is the cups of cashews and y is the cups of almonds.

We can write two equations:

x / y = (1/3) / (1/4) = 4/3

x + y = 28

Solve the system of equations using substitution.

x = 4/3 y

4/3 y + y = 28

7/3 y = 28

y = 12

x = 16
