Answer:
44
Step-by-step explanation:
Given that Avi used 11 toothpicks to form a row of 5 attached triangles.
Total number of toothpicks used = 89
Let the total number of triangles formed be represented by x, so that:
11 toothpicks = 5 triangles
It would be observed that only the first triangle starting the pattern has 3 toothpicks. So that;
the average number of toothpicks for 1 triangle = 
= 2.2
The number of toothpicks per triangle = 2.0
Thus,
x = 
= 44.5
x = 44
The total number of triangles formed is 44.
Answer:
I think it is 1
Step-by-step explanation:
10% of 500 is 50
then you multipy by 50 which is 1
I hope this helps;)
V=side^3
64cubicfeet=side^3
cube both sides
4ft=side
difference=8ft-4ft=4ft
the difference is 4ft
Answer:
f(-3) = 16
Step-by-step explanation:
You substitute -3 to x.
f(-3) = 2(-3)² - 5(-3) - 17
f(-3) = 16.
As for the coordinates, the coordinates plotted in the graph above are (1,-1) and (2,-2).
