How long will it take for the money to triple? Compounded continuously.

Artemon [7]

The formula for compounded continuously is :

$A=Pe^{rt}$

Here the Amount triples , so let us say the new amount A=3P

$3P=Pe^{rt}$

Cancelling P from both sides we get,

$3=e^{rt}$

Now here we are given rate is 2.75% or 0.0275,

$3=e^{0.0275t}$

solving for t we get

t=39.95 years

What is the greatest common factor of 72^2y and 18xy?

sineoko [7]

The GCF of 18 and 72 would be the first step.
the gcf is 18

So we we now have 18 (x^2y)(xy)
factor both variables
18xy would be the gcf

Elisabeth reads 1/5 of her book in 1 1/2 hours. Elisabeth continues to read at this pace. How long does it take Elisabeth to rea

It will take her 5 5/8 hours to read 3/4 of the book

<h3>Ratio and proportions</h3>

Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:

0.2 of a book = 1.5 hours

In order to determine the time taken to read 0.75 part of the book, we will have:

0.75 of a book = x

Take the ratios

0.2/0.75 = 1.5/x

0.2x = 1.125

x = 1.125/0.2

x = 5.625

Hence it will take her 5 5/8 hours to read 3/4 of the book

The diagonal of a square is x units. What is the area of the square in terms of X?

lesantik [10]

Answer:

$\frac{1}{2}x^2$ square units

Step-by-step explanation:

The simple formula we need here is:

$d=s\sqrt{2}$

Where

d is length of diagonal

s is length of side of square

Let's find side length of square from information given:

$d=s\sqrt{2} \\x=s\sqrt{2} \\s=\frac{x}{\sqrt{2}}$

Now,

we know area of square is $s^2$

We know s, and now we find area

Area = $s^2\\(\frac{x}{\sqrt{2}})^2\\\frac{x^2}{2}\\\frac{1}{2}x^2$

The first answer choice is right, 1/2x^2 sq. units.
