Answer:

The height of the giraffe is 27.432 decimeters.

Step-by-step explanation:

To convert 1 foot to decimeters you would multiply by 3.048.

We need to multiply 9 feet by 3.048 which would give you the answer of 27.432 decimeters.

Help with this algebra question

If two lines are perpendicular, the slope of one of the lines is the negative reciprocal of the other. Since we know the slope for one of our lines, $2$ m lets find the other:
$m=- \frac{1}{2}$

Now, lets use the point-slope formula to complete the equation of our perpendicular line:
$y-y_{1}=m(x-x_{1})$
$y-5=- \frac{1}{2} (x-2)$
$y-5=- \frac{1}{2}x+1$
$y=- \frac{1}{2} x+6$

We can conclude that our perpendicular line is $y=- \frac{1}{2} x+6$

$$\frac{(x+1)(x-3)}{x^{2}}$

Solution:

Given expression:

$$\frac{\frac{36}{x^{2}}+\frac{36}{x}}{\frac{36}{x-3}}$

To solve this expression:

$$\frac{\frac{36}{x^{2}}+\frac{36}{x}}{\frac{36}{x-3}}$

Apply the fraction rule: $$\frac{a}{\frac{b}{c}}=\frac{a \cdot c}{b}$

$$=\frac{\left(\frac{36}{x^{2}}+\frac{36}{x}\right)(x-3)}{36}$

Let us solve $\frac{36}{x^{2}}+\frac{36}{x}$ .

Least common multiple of $x^{2}, x$ is $x^{2}$ .

Make the denominator same based on the LCM.

So that multiply and divide the 2nd term by x, we get

$$\frac{36}{x^{2}}+\frac{36}{x}=\frac{36}{x^{2}}+\frac{36 x}{x^{2}}$

$$=\frac{36+36 x}{x^{2}}$

Now, multiply by (x - 3).

$$\frac{36+36 x}{x^{2}}(x-3)= \frac{(36 x+36)(x-3)}{x^{2}}$

$$\frac{\left(\frac{36}{x^{2}}+\frac{36}{x}\right)(x-3)}{36}=\frac{\frac{(36 x+36)(x-3)}{x^{2}}}{36}$

Apply the fraction rule: $\frac{\frac{b}{c}}{a}=\frac{b}{c \cdot a}$

$$=\frac{(36x+36)(x-3)}{x^{2} \cdot 36}$

$$=\frac{36(x+1)(x-3)}{x^{2} \cdot 36}$

Cancel the common factor 36.

$$=\frac{(x+1)(x-3)}{x^{2}}$

Hence the solution is $\frac{(x+1)(x-3)}{x^{2}}$ .
