What is 3 divided by 12 over 5

Principal = $ 15000, rate = 10% p.a. and time 21/5 years PLS HELP ASAP

denpristay [2]

Answer:

Simple Interest: A=P(1+rt)

A=15000(1+(0.1*4.2))

A=$21,300

Compound Interest:A=P(1+r/n)^nt

A=15000(1+0.1/4.2)^1*4.2

A=$64,500

At 10 percent interest, how long does it take to quadruple your money?

horsena [70]

It takes about 14.55 years for quadruple your money

Solution:

Given that,

At 10 percent interest, how long does it take to quadruple your money

Rule of 144:

The Rule of 144 will tell you how long it will take an investment to quadruple

Here,

Rate of interest = 10 %

Therefore, number of years to quadruple your money is obtained by dividing 144 by 10

Rule of 144 Formula:

$N = \frac{144}{R}$

Where:

N = Number of many years times.

144 = Is the constant variable.

R = Rate of interest.

$\rightarrow N = \frac{144}{10} = 14.4$

Thus it takes about 14.4 years for quadruple your money.

Another method:

If initial amount is $ 1 and it if quadruples it should be $ 4

We have to find the number of years if rate of interest is 10 %

Let "n" be the number of years

Then we can say,

$Amount = Principal(1+\frac{R}{100})^n$

$4 = 1(1+\frac{10}{100})^n$

$4 = 1(1+0.1)^n\\\\4= 1(1.1)^n\\\\4 = 1.1^n\\\\We\ know\ that,\\\\(1.1)^{14.55} = 1.1^n\\\\We\ know\ that\\\\If\ a^m = a^n\ then\ m = n\\\\Therefore,\\\\14.55 = n\\\\n = 14.55$

Thus Option D 14.55 years is correct

Carla purchased a hat for $12, a purse for $26, and a dress for $125. The sales tax rate was 5.6 percent. What was the total amo

muminat

Answer:

5/100 = 0.056 sales tax

$12+$26+$125 = $163 total purchase without tax

163*0.056 = 9.128 tax based on how much she bought

$163 + 9.128 = $172.128 total amount she paid (b)

gde Sta manut Stree and Lincoln Set orm a right triangle with a trafic light at each intersection. The distance between the traf

earnstyle [38]

The diagram is of a right triangle with

Hypotenuse = 233

One leg of the triangle = 105

Another Leg = we have to find

Pythagorean Theorem can be written as:

$\text{Leg}^2+\text{AnotherLeg}^2=\text{Hypotenuse}^2$

Thus, we can write:

$\begin{gathered} 105^2+\text{AnotherLeg}^2=233^2 \\ \text{AnotherLeg}^2=233^2-105^2 \\ \text{AnotherLeg}^2=43264 \\ \text{AnotherLeg}=\sqrt[]{43264} \\ \text{AnotherLeg}=208\text{ ft} \end{gathered}$

Thus,

The distance between the traffic lights on Walnut Street is:

208 feet

Madison measured her paper. It was 2/3 feet wide and 1/4 foot long. What is the area of her paper

IRISSAK [1]

Answer:

1/6 squared feet or 0.17 squared feet

Step-by-step explanation:

Since it's a paper, we assume it is a rectangle.

Use the formula for area of a rectangle. A= lw

l is the length and w is the width.

The width is 2/3 feet and the length is 1/4 feet.

Substitute w = 2/3 and l=1/4 into the equation for area of a rectangle.

A = lw

A = (1/4)(2/3) Multiply both numerators, then both denominators

A = 2/12 Simplify. Top and bottom are divisible by 2

A = 1/6

A ≈ 0.17 Rounded to two decimal places

When you multiply two numbers with units, the answer's unit becomes the squared unit.

Therefore the area of her paper is 1/6 squared feet, or 0.17 squared feet.
