Everything you're posting involves right triangles, and
each one is solved with the Pythagorean formula:

              (one leg)² + (other leg)² = (hypotenuse)²

For the tree . . .
Do you see the right triangle ?
They even marked a little box at the base of the stump
to remind you that there's a right angle there.

-- The stump is 3 meters high.
-- The broken part of the tree is on the ground
    13 meters away from the stump.
--  The broken part of the tree is the hypotenuse.
       (3)² + (13)² = (broken part)²

-- Before it fell over, the broken part stood on top of the 3-meter stump.

==========================================

#4).  Your coordinates for point 'G' are correct, but
the coordinates of point 'F' should be (-1, 6), not (1,6).
If you know how to calculate the distance between 2 points,
then that little correction might fix the problem you're having.

The distance between two points is

        Square root of [ (x₁-x₂)² + (y₁-y₂)² ]
or
       Square root of [ (difference of the x's)² + (difference of the y's)² ] .

Without even using this formula, you could just look at
the graph, and do something like this:

-- From 'F', draw a line 2 units straight down.

-- From 'G', draw a line 4 units to the left.

-- Connect 'F' and 'G' .

Now you have a little right triangle.
The legs are 2 units and 4 units.
The hypotenuse is the distance between 'F' and 'G'.

   (2)² + (4)² = (that distance)²

Pete has an old playstation that he bought for $400.
katrin2010 [14]

Answer:

1 year= $280

Step-by-step explanation:

30% of 400= 0.3 * 400= 120

400-120= 280

after one year the playstation cost 280

30% of 280= 0.3 * 280= 84

280-84= 196

after 2 years it cost $196

multiply the number by 0.3 to get 30% of the total

A rectangular billboard is 9.35 meters wide and 6.82 meters tall what is the perimeter of the billboard in meters?
kati45 [8]
-The perimeter is the length of the line if the whole rectangle was straightened out.
-a rectangle has 2 sets of 2 even sides. The top and bottom width would be equal and the two heights would be equal

Armed with these two facts we know the perimeter would be Side A + Side B + Side C + Side D
9.35 + 9.35 + 6.82 + 6.82 = ?

The actual formula for a rectangle or even a square is
2(length + width)
