Answer:

One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?

Step-by-step explanation:

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years

Write a two colon proof for each
Sladkaya [172]

We use the SSS congruence rule to prove the triangles to be congruent. From there, we then use CPCTC to show that angle I is congruent to angle L.

This is shown in the two column table (attached image below)

-----------

Notes:

SSS = side side side

CPCTC = corresponding parts of congruent triangles are congruent

Plz help asap 25 points

Answer:

$14.39

Step-by-step explanation:

The formula for continuous compounding of interest is:

A = Pe^(rt), were P is the initial dollar amount, A is the final amount, r is the interest rate as a decimal fraction, and t is the time in years.

Here we have  $2109 = $500e^(10r) and need to solve for r.

To do this, take the natural log of both sides, obtaining:

ln 2109 = ln 500+ 10r.

Then 10r = ln 2109 - ln 500, and

         ln 2109 - ln 500

r = --------------------------------------------

                         10

 =  .1439

The interest rate was 14.39%.
