A microscope has a setting that magnifies an object so that it appears 100 times as large when viewed through the eyepiece. If a
3241004551 [841]

The length of the insect in the final image is \boxed{9.5\text{ centimeter}}.

Further explanation:

In the question it is given that if an object is viewed under a microscope then the object appears 100 times large than its original size.

It is given that the length of a insect is 0.095 centimeter.

This question is based on the concept of multiplication of decimals.

Consider the length of the insect as x\text{ cm}.

Since, the length of insect is 0.095 centimeter so, trhe value of x is 0.095.

As per the question the size of the final image is 100 times large as the original size so, the size of final image is calculated as follows:

\boxed{S=x\times 100}

Substitute 0.095 for x in the above equation.

\boxed{\begin{aligned}S&=x\times 100\\&=0.095\times 100\\&=9.5\end{aligned}}

From the above calculation it is concluded that the length of the insect in the final image is 9.5\text{ centimeter}.

Therefore, the length of the insect in the final image is \boxed{9.5\text{ centimeter}}.

One can solve this by first using order of operations, and then combining like terms.


First is parenthesis


9x + 2x(9) - 2(9x)


Now we do the multiplication


9x + 18x - 18x


Now we combine like terms


9x
