If I want to earn $100 on a 3-month CD that pays 4% annual simple interest, how much must I invest?

keeping in mind that 3 months is not even a year, but since there are 12 months in a year, 3 months is really 3/12 years, therefore,


\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill&100\\ P=\textit{original amount deposited}\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\to \frac{3}{12}\dotfill &\frac{1}{4} \end{cases} \\\\\\ 100=P\left( 0.04\cdot \frac{1}{4} \right)\implies 100=P(0.01)\implies \cfrac{100}{0.01}=P\implies 10000=P

How do you find the area of a triangle
natita [175]
Use the formula:

\frac{b\: \times \:h}{2}

B refers to the base and H refers to the height of the triangle.

As such, multiply both the base and height of the triangle and divide the answer by 2, to find the area of the triangle.

How can i learn times faster like 3's til 12's in Times i have a hard time in my times can someone tell me how i can learn them
iogann1982 [59]
To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows

12's:

0    0 = 12 x0
1    2 = 12 x1
2    4 = 12 x2
3    6 = 12 x3
4    8 = 12 x4
6    0 = 12 x5
7    2 = 12 x6
8    4 = 12 x7
9    6 = 12 x8
10  8 = 12 x9
12  0 = 12 x10
13  2 = 12 x 11
14  4 = 12 x 12
