<u>The rule of 72  </u>

It is a simplified way to determine, If we invest some amount, how long that investment will take to double,

<u>Formula </u>

Let R be the rate of interest,

The time required to take double the amount = 72/R

<u>Calculate the approximate years</u>

According to the rule of 72, approximately 12.63 ≈ 13 years will it take for her money to double

Write each decimal as a percent and a fraction -0.04
Annette [7]

Answer:

-4%   -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

\frac{-0.04}{1} x \frac{100}{100} = \frac{-4}{100}

-4/100 simplified = -1/25 <em>(because </em><em>4</em><em> goes into </em><em>100</em><em> 25 times)</em>

What are the values of x and y for this system of equations? <br> 2x + y = -1 <br> -x + 3y = 18
DedPeter [7]
X=-3 and y=5
2x+y=-1

-x+3y=18
3y-18=x

2(3y-18)+y=-1
6y-36+y=-1
7y=-1+36
7y=35
y=35/7
y=5

-x+3y=18
-x+3(5)=18
-x+15=18
-x=18-15
-x=3
x=-3

Please help! :) (Whoever answers first I'll give Brainlest!)
Taya2010 [7]

Answer:

The answer is [10+(9x3]+4 and 5x4+(7x3).

Step-by-step explanation:

I can't really explain, but if you add 10+4, it'll be 14.

If you multiply 9x3, it'll be 27.

So, if you add 27+14, it will be 41.

For the second answer:

If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.

A pair of dice is tossed twice. Find the probability that both rolls give a sum of 9. (Enter your probability as a fraction.)
maria [59]

Answer: \dfrac{1}{9}

Step-by-step explanation:

We know that the a dice has total 6 outcomes.

When a pair of dice is tossed then the total number of outcomes will be :-

6\times6=36

The outcomes of that shows sum to be 9:-

(3,6),\ (6,3),\ (5,4),\ (4,5),\

Now, the  the probability that both rolls give a sum of 9 will be :_

\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}\\\\=\dfrac{4}{36}=\dfrac{1}{9}\

Hence, the probability that both rolls give a sum of 9 = \dfrac{1}{9}
