The projected T. rex is about

dolphi86 [110]

Answer: $scale\ factor=230$

Step-by-step explanation:

You need to analize all the information given in the exercise.

You know that the actual height of the T-rex on the projector lens is the following:

$actual\ height=2\ cm$

The height of the projected T-rex is:

$projected\ height=4.6\ m$

Make the conversion from meters to centimeters:

$projected\ heigth=(4.6\ m)(\frac{100\ cm}{1\ m})\\\\projected\ heigth= 460\ cm$

Therefore, the scale factor will be:

$scale\ factor=\frac{projected\ heigth}{actual\ heigth}$

Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:

$scale\ factor=\frac{460\ cm}{2\ cm}\\\\scale\ factor=230$

The new total is 60%, but the sales tax is 5% of the bill. how much is the salestax?

Nataly_w [17]

Answer:

Sales tax is 8.33 % of new total

Step-by-step explanation:

Let

Your bill =1000

New total 60%=1000*60/100=600

5% sale tax on whole bill price =1000*5/100=50

To deduct 5% sale tax in 60% of new total the % are=50/600=0.0833*100=8.33%

So,

Sale tax is 8.33% of new total 60%.
