Answer: Last option.
Step-by-step explanation:
By definition, Inverse variation equations have this form:
Where "k" is the constant of variation.
In this case, it is:
Knowing that 
when 
, we can substitute values into the equation and solve for "k":
Therefore, we can find the value of "n" when 
by substiuting this value and the value of "k" into the equation and solving for "n". Then:
The answer would be 10,because 10x10=100
Answer:
B) 50º
Step-by-step explanation:
first we need to find angle MPL. to do this we do 180 - 70 - 60 = 50º. angle KPN is the smae as angle MPL. so angle KPN is 50º.
Answer:
D
Step-by-step explanation:
Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
