Find the total, then divide by the number of plays:

-3 + 2 -1 - 2 - 3 +1 = -6 yards

-6 yards / 6 plays = -1 yard per play average.

The answer is 8
Here's why:
${ ( \frac{( {6}^{7}) \times ( {3}^{3}) }{( {6}^{6}) \times ( {3}^{4} ) } )}^{3} = \\ ( \frac{6}{3} ) ^{3} = \\ \frac{216}{27} = 8$
The exponents are subtracted one from another when divided.
$\frac{ a ^{b} }{ {a}^{c} } = {a}^{b - c}$
We can look at the problem this way:
$( \frac{6^{7} }{6 ^{6} } \times \frac{3^{3} }{ {3}^{4} } ) = (6^{7 - 6} \times {3}^{3 - 4} ) = \\ ({6}^{1} \times {3}^{ - 1} )$
Since we have the power of -1 on the 3, we apply this rule:
${a}^{ - b} = \frac{1}{ {a}^{b} }$
Also this rule because we have the power of 1 on the 6:
${a}^{1} = a$
Then we get this:
$(6 \times \frac{1}{3} )^{3} = ( \frac{6}{3} )^{3}$
We apply the rule:
$( \frac{a}{b}) ^{c} = \frac{ {a}^{c} }{ {b}^{c} }$
We get this:
$\frac{{6}^{3} }{ {3}^{3} } = \frac{216}{27} = 8$

Stacy wants to build a patio with a small, circular pond in her backyard.The pond will have a 6-foot radius. She also wants to i

solong [7]

First we are going to find the Area of the pond using the area of a circle formula: $A= \pi r^2$
where
$A$ is the area of the circle
$r$ is the radius of the circle
We know for our problem that the pond will have a 6-foot radius, so $r=6$ . Lets replace that value on our area formula:
$A= \pi r^2$
$A= \pi (6)^2$
$A=113.1ft^{2}$
We know that the cost of installing the pond is $0.62 per square foot, so lets multiply the area we just found by the cost:
Total cost of pund= $(0.62)(113.1)=70.12$ dollars

Now, let $x$ be the width the rectangle, so its length will be $x+13$ . Remember that the area of a rectangle is width times length, so:
$A=x(x+13)$
$A=(x^2+13x)ft^2$
Since the cost of installing ties is $1, the cost of installing ties in our rectangle will be x^2+13x dollars.

Stacy can spend no more than $536 on this project, so we can setup an inequality relating the cost of the pound and the cost of installing ties:
 $70.12+x^2+13x \leq 536$
$x^2+13x \leq 465.88$

We can conclude that the inequality that can be used to fin the width, $x$ , of the patio is $x^2+13x \leq 465.88$
