The x-axis shows the independent variable and the y-axis shows the dependent variable. so therefore the x-axis will be the years and the y-axis will be the subscribers. hope this helped!
There is only one repeating number, so we multiply both sides by
or
.
Now subtract the original number we had to both sides, which is the same as
or
So we have:
Divide 9 to both sides:
Multiply the fraction by 10 to get rid of the decimal in the numerator.
Simplify the fraction by dividing the numerator and denominator by 2:
Area of a sector of a circle is (Angle of Sector/360°)*πr^2
If you plug in the given values, you get (30°/360°)*36π
Simplify the equation.
(1/12)*36π
Simplify the equation again and you get your answer.
Area = 3π
Answer:
length: 20 width:35
Step-by-step explanation:
The answer is 80 ft.
Based on the diagram we know that the tree triangle and the building triangle are similar triangles where the lengths of each are proportional to the other.
The lengths of the triangle the tree makes are half of the lengths of the building triangle. So this problem can be solved using ratio and proportion:
to solve for x, all you need to do is cross multiply then divide.
The answer is then 80ft.
Another way to solve this is just by using logic. If the lengths of the tree triangle is half of the building, simply divide the lengths of the building triangle by two.
160ft/2 = 80ft.
