100-64=36 percent wrong
if 36% is 18 questions
then, 36/18=2
every question is 2% grade
100/2=50 questions in total
Answer:
y=3x-21
Step-by-step explanation:
y=mx+c
y=3x+c
3=24+c
c=-21
y=3x-21
Consider the vertices of parallelogram JKLM with vertices J(2,2) , K(5,3) , L(5,-3) and M(2,-4).
Perimeter JKLM = Length JK + Length KL + Length LM + Length JM
Length JK = (2,2) (5,3)
The length(or distance) between two points say and is given by the distance formula:
Now, length JK =
= units
Since, JKLM is a parallelogram. In parallelogram opposite sides are equal in length.
Therefore, LM = units
Now, length KL =
= 6 units
Since, JKLM is a parallelogram. In parallelogram opposite sides are equal in length.
Therefore, JM = 6 units
Perimeter of JKLM = + + 6 + 6
= 2 + 12
= 18.324
Rounding to the nearest tenth, we get
= 18.3 units.
Therefore, the perimeter of JKLM is 18.3 units.
