Bryce did chores every single day in september.It took Bryce 7/8 hours to completing his chores on 20 of the days.The remaining

omeli [17]

Answer:

Step-by-step explanation:

Because Bryce did 7/8 hours every day for 20 days,

7/8 hours is 52.5 minutes.

so then times 20, you will get 1050 minutes.

Then divided by 60(minutes per hour) you will get 17.5 hours,

which means she did 17 hours and 30 minutes in the first 20 days,

then you plus the last 1 hour per day for 10 days,

you will get 10 hours plus 17 hours and 30 minutes.

So Bryce have worked 27 and 30 minutes in september.

Match the products of rational expressions with their simplest forms.

Alborosie

Lets simplify each one of the rational expressions using the product rule of exponents: $a^n*a^m=a^{n+m}$ and the quotient rule of exponents: $\frac{a^n}{a^m} =a^{n-m}$ .

1. $\frac{-3x^2}{2y^2} * \frac{y^2}{9x} =- \frac{x}{6} = \frac{-1}{6} x$

2. $\frac{5y^2}{10x^2} * \frac{4x^2}{y} =2y$

3. $\frac{-9y^2}{5x} * \frac{-10x^2}{3y} =6xy$

4. $\frac{14x^2}{5y} * \frac{-10y}{7x} =-4x$

We can conclude that you should pair the rational expressions with their simplest form as follows:
$6xy-----\ \textgreater \ \frac{-9y^2}{5x} * \frac{-10x^2}{3y}$
$\frac{-1}{6} x-----\ \textgreater \ \frac{-3x^2}{2y^2} * \frac{y^2}{9x}$
$-4x-----\ \textgreater \ \frac{14x^2}{5y} * \frac{-10y}{7x}$
$2y-----\ \textgreater \ \frac{5y^2}{10x^2} * \frac{4x^2}{y}$
