To solve this problem you must apply a theorem called: Intersecting secant theorem. The proccedure is shown below:
1) For the figure shown on the left:
(5)(x+5)=(6)(4+6)
5x+25=60
5x=60-25
x=35/5
x=7
2) For the figure shown on the right:
(3)(3+5)=(4)(x+4)
24=4x+16
24-16=4x
8=4x
8/4=x
x=2
First convert all the units into millimetres.
1 metre = 1000 millimetres
10 metres = 10000 millimetres
2 : 1000 :: x : 10000
Remember this: <u><em>Product of means is equal to the product of extremes.</em></u>
<u><em></em></u>
2 × 10000 = 1000x
20000 = 1000x
∴ x = 20000 ÷ 1000
x = 20 millimetres

Well r equals what ever number same for the c then what numbers you get from those 2 add to the p
You may solve this ratio by cross multiplying. To do this, you multiply the numbers diagonally across from each other.
x/10 = 1/5
10(1) = x(5)
10 = 5x
2 = x
Answer:
x = 2
This is just a porportion. So if 250 meters is 1 meter than: 250/1
And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x
Set them equal to each other 250/1=212/x
Cross multiply: 212=250x
Divide to find x: 212/250=x
x=212/250
x=0.848
So the height of the model, to the nearest 10th would be 0.8 meters.
