Find the difference and reduce to the lowest terms 12 4/9 - 8 5/6 =

butalik [34]

Answer: $3\frac{11}{18}$

Turn 12 4/9 into an Improper Fraction

Multiply $12*9$ and get $108$ . Now add $4$ and get $112$ .

$12\frac{4}{9} =\frac{112}{9}$

Turn 8 5/6 into an Improper Fraction

Multiply $8*6$ and get $48$ . Now add $5$ and get $53$ .

$8\frac{5}{6} =53/6$

Find Common Denominator

$9: 9,18,27,36,45\\6: 6,12,18,24,30\\\CD=18$

Your new problem: $\frac{112}{18}-\frac{53}{18}$

Subtract

$\frac{112}{18}-\frac{53}{18}=\frac{65}{18}$

Simplify

$\frac{65}{18} =3\frac{11}{18}$

HELPPP PLEASEEE!!! I DON’T GET THIS AND I START SCHOOL TOMORROW

Lorico [155]

Queston 4: The range of the relation is : (-2,4)

Question 5: the domain of the relation is:
{2, 2.1, 5.1, 5.5, 6}

Question 6: The relation is not a function because it two of the x value have the same y values. Therefore it is not a function as it does not pass the vertical line test.
(-4, 0) and (-3, 0) both have 0 for the y coordinate. A function can’t have this.

You decide to put $5000 in a savings account to save $6000 down payment on a new car. If the account has an interest rate of 7%

bezimeni [28]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill&\$6000\\ P=\textit{original amount deposited}\dotfill &\$5000\\ r=rate\to 7\%\to \frac{7}{100}\dotfill &0.07\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years \end{cases}$

$\bf 6000=5000\left(1+\frac{0.07}{12}\right)^{12\cdot t}\implies \cfrac{6000}{5000}\approx (1.0058)^{12t}\implies \cfrac{6}{5}\approx(1.0058)^{12t} \\\\\\ \log\left( \cfrac{6}{5} \right)\approx \log[(1.0058)^{12t}]\implies \log\left( \cfrac{6}{5} \right)\approx 12t\log(1.0058) \\\\\\ \cfrac{\log\left( \frac{6}{5} \right)}{12\log(1.0058)}\approx t\implies 2.63\approx t\impliedby \textit{about 2 years, 7 months and 16 days}$
