Answer:

1.3cm

Step-by-step explanation:

The scale from the actual coin to the photo is 8 mm to 2 cm In the photo,

converting 8mm to cm = 0.8 cm

using ratio and proportion,

if 2cm = 3.25 cm

then 0.8cm = ? less

if less then more devides.

thus ; (0.8cm ÷2cm ) × 3.25cm =

( 0.4) × 3.25cm = 1.3cm

therefore the distance across the actual coin is 1.3cm.

What are evidence that the himalayas mountains are still rising​
xeze [42]

Answer:

The Himalayas are still rising by more than 1 cm per year as India continues to move northwards into Asia, which explains the occurrence of shallow focus earthquakes in the region today. However the forces of weathering and erosion are lowering the Himalayas at about the same rate.

netineya [11]

Answer:

Please look at the image.

I solved this by the information of 6 pages in 12 minutes which means 0.5 or half a page per minute.

Now you know you read half a page in a minute

5 pages in 10 minutes because:

10 × 0.5 = 5

8.5 pages in 17 minutes because:

17 × 0.5 = 8.5
