Divide 81 -x^2 y^2 by (9-xy) (3 + xy)​

Mathematics
1 answer:
Eva8 [605]3 years ago
8 0

Answer:

When we divide 81 -x²y² by (9-xy) (3 + xy)​, we determine the expression is:

\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{9+xy}{3+xy}

Step-by-step explanation:

Let us divide 81 -x²y² by (9-xy) (3 + xy)​

so

Given the expression

\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}

Factor -x²y² + 81 = (9+xy) (9-xy)

\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{\left(9+xy\right)\left(9-xy\right)}{\left(9-xy\right)\left(3+xy\right)}

Cancel the common term: 9-xy

                    =\frac{9+xy}{3+xy}

Therefore, when we divide 81 -x²y² by (9-xy) (3 + xy)​, we determine the expression is:

\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{9+xy}{3+xy}

What is the volume of a cone with a diameter of 8 centimeters and a height of 14 centimeters? (Use 3.14 for .)
Natali [406]

Answer:

Volume of cone =  234.45 cm³

Step-by-step explanation:

Given:

Diameter = 8 cm

Radius r = 8 / 2 = 4 cm

Height h = 14 cm

Find:

Volume of cone

Computation:

Volume of cone = (1/3)πr²h

Volume of cone = (1/3)(3.14)(4)²(14)

Volume of cone =  234.45 cm³

A total of 30 percent of the geese included in a certain migration study were male. If some of the geese migrated during the stu
Serggg [28]
<h2>Answer:</h2>

<em><u>(B). </u></em>\frac{7}{12}

<h2>Step-by-step explanation:</h2>

In the question,

Let the total number of geese be = 100x

Number of Male geese = 30% = 30x

Number of Female Geese = 70x

Let us say 'kx' geese migrated from these geese.

Number of migrated Male geese = 20% of kx = kx/5

Number of migrated Female geese = 4kx/5

So,

<u>Migration rate of Male geese</u> is given by,

\frac{(\frac{kx}{5})}{30x}

<u>Migration rate of Female geese</u> is given by,

\frac{(\frac{4kx}{5})}{70x}

So,

The ratio of Migration rate of Male geese to that of Female geese is given by,

\frac{\left[\frac{(\frac{kx}{5})}{30x}\right]}{\left[\frac{(\frac{4kx}{5})}{70x}\right]}=\frac{350}{4\times 150}=\frac{7}{12}

Therefore, the<em><u> ratio of the rate of migration of Male geese to that of Female geese is,</u></em>

\frac{7}{12}

<em><u>Hence, the correct option is (B).</u></em>

<em><u></u></em>
