Emma has money into savings accounts. One rate is 8% and the other is 12%. If she has $450 more in the 12% account and the total
AveGali [126]

Let's say that the value invested in the account with a rate of 8% is "x", then the amount invested in the account with a rate of 12% is:

x+450

To calculate the total interest we need to calculate the interest of each individual account and sum them:

\begin{gathered} \frac{8}{100}\cdot x=0.08\cdot x \\ \frac{12}{100}\cdot(x+450)=0.12\cdot x+54 \end{gathered}

The total interest is the sum of the two expressions above:

\begin{gathered} 220=(0.08\cdot x)+(0.12\cdot x+54) \\ 220=0.08\cdot x+0.12\cdot x+54 \\ 220-54=0.2\cdot x \\ 166=0.2\cdot x \\ 0.2\cdot x=166 \\ x=\frac{166}{0.2} \\ x=830 \end{gathered}

The value invested in the account with 8% interest is 830, the one invested in the account with 12% interest is 1280.

Answer:

The distance between E and F is 5 units

Step-by-step explanation:

<em>E</em><em> </em><em>and</em><em> </em><em>F</em><em> </em><em>are</em><em> </em><em>share</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>y-coordinates</em><em>.</em><em> </em><em>So</em><em> </em><em>for</em><em> </em><em>this</em><em> </em><em>part</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>okay</em><em> </em><em>to not</em><em> </em><em>use</em><em> </em><em>the</em><em> </em><em>distance</em><em> </em><em>formula</em><em>.</em><em> </em>

<em>So</em><em> </em><em>you</em><em> </em><em>will</em><em> </em><em>be</em><em> </em><em>having</em><em>:</em>

<em>E</em><em> </em><em>(</em><em>5</em><em>,</em><em>8</em><em>)</em><em> </em><em>and</em><em> </em><em>F</em><em> </em><em>(</em><em>5</em><em>,</em><em>3</em><em>)</em>

<em>EF</em><em> </em><em>=</em><em> </em><em>8-3</em><em>=</em><em>5</em>

<em>OR</em><em> </em>

<em>YOU</em><em> </em><em>CAN</em><em> </em><em>USE</em><em> </em><em>THE</em><em> </em><em>DISTANCE</em><em> </em><em>FORMULA</em><em> </em><em>AS</em><em> </em><em>INDICAYED</em><em> </em><em>IN</em><em> </em><em>THE</em><em> </em><em>PICTURE</em><em>.</em>

<em>Hopefully</em><em> </em><em>the picture</em><em> </em><em>is clear and understandable</em><em> </em><em>and</em><em> </em><em>younger</em><em> </em><em>the</em><em> </em><em>explanation</em><em>.</em>
