if x varies directly with y, and x=9 when y =6, find x when y = 15
explain
Direct variation problems use the equation y = kx
Replace y and X with the two known numbers to solve for k:
6=k9
Solve for K by dividing both sides by 9:
k = 6/9, reduces to 2/3
Now replace y and k into the formula to solve for x:
15 = 2/3x
Solve for X by dividing both sides by 2/3:
X = 15 / 2/3
X = 45/2 as an improper fraction, 22 1/2 as a proper fraction or 22.5 as a decimal.
Not sure which format the answer needs to be in, so I gave all three.

Step-by-step explanation:
If it has two pairs of parallel sides it is a parallelogram, but parallelograms are also trapezoids.
14.58 feet
36.65 feet
175 inches
Answer: 36.65 inches
Step-by-step explanation:
The length of arc with a central angle x and radius r in a circle is given by :-
Given : Radius of a circle = 60 inches
Central angle =
Now, the of length of arc is given by :-
Hence, the length of arc = 36.65 inches.
Answer:
36.65 inches
Step-by-step explanation:
To calculate arc length, multiply theta (in radians) with radius.
First, convert 35 degrees to radians (35pi)/180= 0.61087
Then, multiply by 60 inches= 36.65
36.65 inches
