Ok so the first thing you are going to do is chang the percentage into a decimal. 12 percent would change into 0.12, because in order to change a percentage into a decimal you move the decimal two places to the left. Next you would multiply 0.12 by 45 which gives you 5.4. But we are not done yet. By multiplying 0.12 x 45 we find how much weight she has gained. So our next and final step should be add 5.4 to 45 which gives us 50.4. Therefore your answer should be 50.4kg
Hope this helps!!!

The length of a sticky note measures 77 millimeters.express this length in meters explain your thinking include an equation with
Eva8 [605]

The length of the sticky notes is \bf77\times{10^{-3}}{\text{meter}}.

Further explanation:

Given:

The length of sticky notes is measured as 77 millimeters.

Calculation:

Since 1 meter contains 1000 mm, it can be written as follows:

\begin{aligned}1000{\text{mm}}&\to{\text{1meter}}\\{\text{1mm}}&\to\frac{{\text{1}}}{{1000}}{\text{meter}}\\{\text{1mm}}&\to{10^{-3}}{\text{meter}}\\x\,{\text{mm}}&\to x \times {10^{-3}}{\text{meter}} \\ \end{aligned}

Now, substitute 77 for x in above expression to obtain the length of sticky notes in meter as follows:

77\,{\text{mm}}\to77\times{10^{-3}}{\text{meter}}

Thus, the length of the sticky notes is \bf77\times{10^{-3}}{\text{meter}}.
