Solve for L: d=LM/R2+R1

Answers

Answer 1

Answer: d=LM/(R2+R1)
d(R2+R1)=LM
[d(R2+R1)]/M=L

Answer 2

Answer:

Answer:

Given the equation: $d = (LM)/(R_2+R_1)$ .....[1]

Cross multiply states that an equation of fractions when each of the side consists of a fraction with a single denominator by multiplying the numerator of each side by the denominator of the other side and equating these two products obtained.

Apply the cross multiply in [1], we get;

$d(R_2 +R_1) = LM$

Divide both sides by M we get;

$L = (d(R_2+R_1))/(M)$

$L = (dR_2+dR_1)/(M)$

During a sale, a shop allows 20% discount off the marked price of clothing. What will a customer pay for a dress with a marked price of $30? * 1 point

Answers

Answer:

$24

Step-by-step explanation:

Let the full price of $30 be 100%.

If the discount allowed is 20%, then the percentage of the original price that a customer will pay is:

$P=100\%-20\%\nP=80\%$

80% of a marked price of $30 is:

$80\%*\$30\n\$24$

A customer will pay $24.

They will pay 24 dollars

the population of China is about 1.4 x 10 to the power of 9 people. Julie grew up in a town with a population of about 7,000 people. How many times greater is the population of China than Julie's hometown? Please answer this in scientific notation.

Answers

Answer:

2 x 10^5

Step-by-step explanation:

Given

Population of China = 1.4 x 10^9
Population of town = 7000 = 7 x 10^3

The difference in population

1.4 x 10^9 / 7 x 10^3 =
14 x 10^8 / 7 x 10^3 =
2 x 10^5

The population of China is 0.2 million times greater than the population of Julie's hometown.

What is the population?

To find out how many times greater the population of China is than Julie's hometown, we can set up a ratio using scientific notation:

Population of China = 1.4 x 10⁹

Population of Julie's hometown = 7,000 = 7 x 10³

Ratio = Population of China / Population of Julie's hometown

Ratio = (1.4 x 10⁹) / (7 x 10³)

Now, divide the numbers and subtract the exponents of 10:

Ratio = $2 * 10^((8 - 3))$

Ratio = 0.2 x 10⁶

So, the population of China is 0.2 million times greater than the population of Julie's hometown.
