Tessellations in Roof

I took this photograph whilst on holiday in Barcelona. It is the roof of a market.

## Bath Canal Bridge – Similar Shapes

Bridge – Similar Shapes

• These circles are similar what does that mean?
• The scale factor of enlargement between each circle is 1.4. Given the diameter of the first circle is 6cm, work out the diameter of the rest.
• Work out the area of the first circle
• Work out the area of the second circle
• What would you multiply the first area by to get the second area? Compare this to the scale factor of enlargement
• What would you multiply the second area by to get the third area? Compare this to the scale factor of enlagement
• Work out the areas of the rest.

## Number, Space – Lift in Turkey 1

Lift in Turkey

Above is a picture from inside of a lift in Turkey.

• It says the weight limit is 1000kg or 13 persons. What is the average weight of a person according to the lift?
• If Mr Corbett weighed 110kg at the time of the picture and there were 12 other people in the lift, what is their maximum average weight.

The lift is currently on level -1, this is where the conference rooms are.

• If the lift went down another 3 levels, which floor would the lift be on?
• If the lift went up 3 levels, which floor would the lift be on?

The lift travels at a maximum speed of 1.00m/s.

• If the lift has been travelling upwards for 14 seconds at the maximum speed, how far has the lift gone up?
• I enter the lift on the Ground floor and press level 8. The lift doors close and the lift starts to move upwards slowly and accelerates uniformly to reach it’s maximum speed after 2 seconds. It travels at it’s maximum speed for 15 seconds, then starts to slow down for 3 seconds where the lift stops on level 8. Draw a Speed-Time graph for this journey.
• Draw a Distance-time graph for the above journey.
