Round #7 7) In 2018, the United States Postal Service (USPS) raised its rates for mailing letters. The new charge was $0.50 to m

Anarel [89]

We know that

• The new charge was $0.50 to mail a letter weighing up to 1 ounce, and $0.21 for each additional ounce.

Based on the given information, the expression is

$y=0.50+0.21x$

Where <em>x</em> represents additional ounces, and <em>y</em> represents a cost.

<h2>Hence, the function is</h2> $f(x)=0.21x+0.50$

Select the equivalent expression.

Free_Kalibri [48]

Answer:

$\frac{7^{15}}{3^{30}}$

Step-by-step explanation:

The given expression is:

$(\frac{3^{-6}}{7^{-3}})^{5}$

Moving the expression to the other side in the fraction changes its sign to opposite. A numerator with negative exponent, when written in denominator will have the positive exponent. Using this rule, we can write:

$(\frac{3^{-6}}{7^{-3}})^{5}\\\\ = (\frac{7^{3}}{3^{6}} )^{5}$

The exponent 5 can be distributed to both numerator and denominator as shown:

$(\frac{7^{3}}{3^{6}} )^{5}\\\\ = \frac{(7^{3})^{5}}{(3^{6})^{5}}$

The power of a power can be written as a product. i.e.

$\frac{(7^{3})^{5}}{(3^{6})^{5}}\\\\ =\frac{7^{15}}{3^{30}}$

So, the expression similar to the given expression and with positive exponents is: $\frac{7^{15}}{3^{30}}$

After sales tax, an $81 cell phone costs $84.24. What is the sales tax percentage?

Igoryamba

Answer:

4% sales tax

Step-by-step explanation:

Take the original costs and subtract it from the price after sales tax.

$84.24-$81= $3.24

Divide 3.24 by 81

this gives you .04, now either multiply by 100 or move the decimal two places to the right to convert the decimal to a percentage.
