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:
$10356,22
Step-by-step explanation:
15500*(1-(6,5/100))^6=10356,22
Step-by-step explanation:
x+3y=-4(eqn1)
x=-4-3y
from (eqn 2)
2(-4-3y)+6y=5
-8-6y+6y=5
y=5+8=13.
y=13
from eqn 1
x+3(13)=-4
x+39=-4
x=-4-39
x=-43.
Y= 75.
Lets try to solve it,
When positive integer x is divided by positive integer y, the remainder is 9
=> x=qy+9;
=> x/y=96.12
=>x=96y+0.12y (so q above equals to 96);
=>0.12y=9
=> y=75.
Hence the value of y would be 75.
