For two lines to be parallel, they must have the same slope...

3y=-5x+15

y=-5x/3 +5, y=mx+b, where m=slope so:

A parallel line with have a slope of -5/3

John is standing in his backyard and decides to estimate the height of a tree. He stands so that the tip of his shadow coincides
Andrew [12]

The tree is 820 inches tall using the similarity of triangles.

To get the height of the tree, we will use the properties of similar triangles expressed as:

\frac{70in}{7ft} = \frac{h}{75ft+7ft}\\\frac{70in}{7ft} = \frac{h}{82ft}\\

  • Note that 1 foot = 12inches
  • 7ft = 84in and 82ft = 984in

  • h is the required height of the tree. Simplify the equation above to get the height "h" and replace feet with inches;

\frac{70}{84} = \frac{h}{984}\\84h =70 \times 984\\84h = 68,880\\h=\frac{68,880}{84}\\h= 820in

Hence the tree is 820 inches tall using the similarity of triangles.
