Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
Answer:
x= -13
y= -28
Step-by-step explanation:
To find the two numbers, write a system of equations with x as one number and y as another:
x-y=15
5x=2y-9
Use substitution to substitute one equation into another. Then solve for the variable.
x=15+y into 5x=2y-9
becomes
5(15+y) = 2y-9
75+5y = 2y- 9
75+3y= -9
3y = -84
y= -28
To find x, substitute y= -28 into one equation.
x - (-28) = 15
x+28 =15
x = 15-28
x=-13
Answer:
Step-by-step explanation:
So, we are given:
First, we should immediately rule out 0 as an answer. This is because the if 
, the equation would be undefined.
Now, cross multiply.
Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).
We didn't run into any possibilities for extraneous solutions.
The anwser is 19 remainder 4
