Step-by-step explanation:
1) y=60°(alternate angle
2) x+60°=180°(exterior angles)
x=180°-60°
x=120°
Note: I'm assuming you mean that
.
Taking the logarithm gives:
Using our rules of logarithms (
), we have:
This corresponds to answer A.
Answer:
1/2
Step-by-step explanation:
It doesn't matter if a die is rolled 27 times or a million times, there will always be an even number of even and odd numbers so the answer is one-half.
You can simplify the right side. Then, you need to take cube roots.
(m -4)³ = 1/(1/8) . . . rule of exponents
(m -4)³ = 8 . . . . . . .simplify
m -4 = ∛8 . . . . . . . take cube roots
m -4 = 2 . . . . . . . . use your calculator or knowledge to find ∛8
m = 6 . . . . . . . . . . add 4
The solution is m = 6.
_____
If you subtract the right side, you get a function of m that is zero when m has the right value. This graph shows that value is m = 6.
