D: -25/27
-5/6 ÷ 9/10 = 5/6 x 10/9 *when diving fractions, use recipricals.*
-5/6 ÷ 10/9 = - 25/27 *just multiply each numerator and denominator*
Length of a circumference=2πr
r=radius=6 feet.
lengt of this circumference=2π6 feet=12π feet.
1 circumference=360º; then:
360º-------------------12π feet
6º---------------------- x
360º * x=6º * 12π feet
x=(6º * 12π feet) / 360º=π/30 feet (≈0,105 feet).
Solution: π/30 feet
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
Answer:
1/10 is the correct answer
Step-by-step explanation:
3/5=6/10
7/10-6/10=1/10
Consider the equation

1) First row of the table
Set x=0 and solve as follows:

The answer is y=20 and the pair x-y is (0,20)
2) Second row
Set x=1 and solve, as follows:

The answers are y=10 and (1,10)
3) Third row.
Set y=0 and solve as follows:

The answers are x=2 and (2,0)
