Simon makes a model of a boat, using a scale of 1 : 30
sergey [27]

Answer: 12 metres

Step-by-step explanation:

The scale factor used for the model is 1 : 30.

This means that for any 1cm on the model, the real boat would be 30 cm.

If the height is 40 cm on the model, the real boat will be 30 times that:

= 40 * 30

= 1,200 cm

A metre is equivalent to 100cm.

1,200 cm would therefore be:

= 1,200/100

= 12 metres

Write in scientific notation <br><br> (2.3x10^8)x(7.84x10^4)
Keith_Richards [23]

Answer: 1.8032 x 10^13

Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the ten. If your decimal is being moved to the right, then the exponent will become negative. If your decimal is being moved to the left, then the exponent will become positive.

I hope this helps you out!
