Ksenya-84 [330]3 years ago
6 0

Answer:

\frac{25}{144}

Step-by-step explanation:

(\frac{7 * 5 * 2}{7 * 3} )^2 * (\frac{5^0}{2^-3})^3 * 2^{-9}

Simplified becomes;

(\frac{10}{3})^2 * 2^3 * \frac{1}{2^9}

Simplifying further gives; \frac{25}{144}

Angela paints a wall that has an area of 42 2/3 square yards. She uses 1 1/3 gallons of paint. What is Angela's rate of paint co
Rina8888 [55]
Yards= 42  2/3 yd=42 + 2/3 yd=(42*3 + 2)/3 yd=128/3 yd
Gallons=1  1/3 Gallons=1+1/3 gallons=(3*1+1)/3 gallons=4/3 gallons.

Rate=number of yards / number of gallons.
Rate=(128/3 yd) / (4/3 gallons)=32 yd/gallon.

Answer: Angela´s rate=32 yards / gallons

What is the answer for No.22 & 23 please
kondor19780726 [428]
Hello!

<u>Number 22</u>: We'd plot the first point at 0 since there is no stated y-intercept. Next, we'd use our slope to determine where to plot the next point, and that would create our line. According to the problem, our slope is -\frac{1}{2}, which automatically tells us that the slope would be going downwards because it's negative. 

To plot our point, use the slope while going down and across from our y-intercept, which is 0. Go down 1, and over 2.

Your points should be at (0, 0) and (-1, 2)


<u /><u>Number 23:</u> This one will be a bit trickier since the equation is not in slope-intercept form. First, let's convert it to slope-intercept form. 

-2x + 3y = 6&#10;&#10;-2x + 2x + 3y = 6 + 2x&#10;&#10;3y = 6 + 2x&#10;&#10;3y/3y = 6/3y + 2x/3y&#10;&#10;y = 2 + 2/3x

Flip some of those numbers around to get our equation in slope-intercept form:

y =  \frac{2}{3}x  + 2

Now to graph this, we do the same as we did for the last problem. Plot our first point at (0, 2), since 2 is our y-intercept. Afterwards, go up 2 and over 3, then plot the other point.

Your points should be at (0, 2) and (4, 3)

Naomi is a songwriter who collects royalties on her songs whenever they are played in
barxatty [35]

Equations can be solved in several ways; one of these ways is the graphical method.

The number of commercials, x, and  the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.

Let:

<em />x \to<em>  commercials</em>

<em />y \to<em> movies</em>

<em />

She earned a total of $300.

This is represented as:

20x + 100y =300

Her songs were played on 3 more commercials than movies.

This is represented as:

x = 3 + y

See attachment for the graphs of

20x + 100y =300

x = 3 + y

From the graph, the lines of both equations intersect at:

x = 5

y = 2

This means that:

  • <em>The number of movies is 2</em>
  • <em>The number of commercials is 5</em>

<em />
