The value of a book is $150 and decreases at a rate of 4% per year. Find the value of the book after 12 years

Answers

If it decreases at 4% every year, then its value becomes:

100% - 4% = 96% = 96/100 = 0.96

At the end of the 1 year its value becomes: 150*(0.96)

At the end of the 2 years its value becomes: 150*(0.96)*(0.96) = 150*(0.96)²

At the end of the 3 years its value becomes: 150*(0.96)*(0.96)*(0.96) = 150(0.96)³

So similarly at the end of 12 years, its value becomes 150*(0.96)¹²

=50*(0.96)¹² simplify with calculator.

≈ 91.91

Value at the end of 12 years becomes ≈ $91.91

I hope this helps.

Sammy pays 30$ for a bag that she buys at discount for 50% what is the price without the discount

Answers

It's just 50%off so all you do is 30 ×2 to get the original price so 30×2=60

Solve for L: d=LM/R2+R1

Answers

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

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;

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

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

The diameter of the Sun is approximately 1,400,000 kilometers, while the diameter of Saturn is approximately 1.2 x 105kilometers. How many kilometers larger is the diameter of the Sun than the diameter of Saturn?a) 1.28 times 10 to the sixth power
b) 1.52 times 10 to the sixth power
c) 1.28 times 10 to the seventh power
d) 1.58 times 10 to the seventh power
(Times means multiply since I have no multiplication sign on my computer)

Answers

Answer:

R = diameter of Sun / diameter of Saturn

R = 1.4E6 / 1.2E5 = 11.6 ratio of diameters

diameter (Sun - Saturn) = 10^6 ( 1.4 - .12) = 1.28 * 10^6
