Guys look at the pic of the park and read the question I need this ASAP WITH ALL STEPS the choices are

Alik [6]

Answer:

A. 821.5 Square Yards

Step-by-step explanation:

30 x 30= 900

900 is the area for the whole park

To find the pool area you need to do pi times Radius squared

so 3.14 x 5 x 5

That equals 78.5 for the pool area.

So to find the grass area you need to subtract the pool area from the park

900 - 78.5 = 821.5 square yards!

Answer:

Step-by-step explanation:

We are given:

$x^a=y^b=z^c$

xyz=1

Separating equations:

$x^a=z^c$

$y^b=z^c$

Solving the first equation for x:

$\displaystyle x=z^\frac{c}{a}$

Solving the second equation for y:

$\displaystyle y=z^\frac{c}{b}$

Substituting in

xyz=1:

$\displaystyle z^\frac{c}{a}z^\frac{c}{b}z=1$

Adding the exponents:

$\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=1$

Since $1=z^0$ :

$\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=z^0$

The base is z on both sides so we get rid of them:

$\displaystyle \frac{c}{a}+\frac{c}{b}+1=0$

Multiplying by ab:

bc+ac+ab=0

Reordering:

ab+bc+ca=0

Easy Question! Find the number that should be added to the expression to create a perfect square trinomial: x^2 − 8x

marysya [2.9K]

Answer: The answer is C

Step-by-step explanation:

Well, an example of a perfect square trinomial would look like is:

$a^2-2ab+b^2$ or $a^2+2ab+b^2$

So since we already know what $a^2$ is and what $2ab$ is we just have to find $b^2$

However, we would use the $a^2-2ab+b^2$ formula to solve this since we have a subtraction sign
