Answer:
Step-by-step explanation:
From the table it is clear that the line is passing through the points 
(There are many other points in the table and any two of them can chosen as per our convenience)
Equation of line in two point form is given as:
That would be 20,30,40,50,60,70,80,90,100,110,120,130. 200,150,300,250
650 + 250 = so the answer would be 900.
For the first question the answer is 1/13. then for the second it is 1/2 and for the third it is 3/10.
Answer:
y=6
Step-by-step explanation:
The building is 76 feet tall. Notice that there's a pair of similar triangles in this diagram: The top of the building, root of the building, and the stake form triangle 1. The top of the tree, root of the tree, and the stake form triangle 2. Since the root of the tree is half way between stake and building, the proportionality between the triangles is 2. Therefore, the building is twice as tall as the tree. 38*2=76.
