Simon makes a model of a boat, using a scale of 1 : 30

Mathematics

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

Darina [25.2K]
Percent decrease : (original number - new number) / original number..*100
                            = (225,000 - 191,250) / 225,000.....* 100
                            = 33,750 / 225,000....* 100
                            = 0.15 * 100
                            = 15% decrease <==

A square park has an area of 1/16 square miles and a length of 1/4 mile. What is
Yakvenalex [24]
<h3>Answer:  1/4 mile</h3>

Explanation:

A square has all four sides the same length. So the length and width are the same.

We can see that (length)*(width) = (1/4)*(1/4) = 1/16 square miles.

If you wanted, you could solve for W in (1/4)*W = 1/16 and you should get W = 1/4.
