In fractional form, I think this is written as

\frac{1}{x-10} / \frac{9x}{ x^{2} -9x-10}

When dividing, the first term is the dividend, the second term is the divisor and the answer is the quotient. When you divide fractions, you multiply the dividend with the reciprocal of the divisor. In this case

\frac{1}{x-10} * \frac{x^{2} -9x-10}{9x }

The answer is 

\frac{ x^{2} -9x-10}{9 x^{2} -90x}

Furthermore, we can simplify the terms through factoring, The numerator could be factored into (x+1)(x-10). The denominator could be factored to 9x(x-10). Since the term (x-10) is common, you can cancel them to get to the final answer which is

(x+1)/9x

if the sum of interior angles of a polygon is 3600 find the number of sides of it. plz want steps too​
riadik2000 [5.3K]

Answer:

22 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 3600° , then

180° (n - 2) = 3600° ( divide both sides by 180° )

n - 2 = 20 ( add 2 to both sides )

n = 22

Joe is 6 feet tall and took a photo of himself beside a statue this summer while visiting Rome. In the picture the Statue is 6 i
Marrrta [24]

Answer:

8 ft

Step-by-step explanation:

Since we are given the size of image and actual object, we need to know the magnification factor. In this case, the man is 6ft but his image is 4.5 inches. Similarly, the statue's height is not given but in the imave it is 6 inches. If 6 ft translates to 4.5 inches then we want to know what translated to 6 inches. We apply the cross multiplication.

6 ft= 4.5inch

X ft=6 inch

X=6 ft* 6 inch/4.5 inch=8 ft

Therefore, the statue is actually 8 ft tall.

Rewrite the following radical expressions as equivalent exponential expressions. <br> a. √5
vivado [14]

Answer:

So in exponential form \sqrt{5} will be equivalent to 5^{\frac{1}{2}}

Step-by-step explanation:

We have given the expression in radical form as \sqrt{5}

We have to find its equivalent in exponential form

We know that if any fraction is in radical form then if we write this in exponential form then in exponential form the exponent come inverse of its number

So \sqrt{5} can be written as 5^{\frac{1}{2}}

So in exponential form \sqrt{5} will be equivalent to 5^{\frac{1}{2}}
