Which is bigger 4/6 or .77
jok3333 [9.3K]
First, let's convert 0.77 to a fraction. 

\frac{0.77}{1}

Multiply by 100

\frac{77}{100}

Now make the denominators the same, to make it easier to find which fraction is greater. We can do this by finding the LCM of the denominators, then however many times the denominator goes into that number, we multiply the numerator by the same amount.

For example, the LCM of 100 and 6, is 300. 6 goes into 300 50 times, so the numerator for 4/6 is 200 (4 x 50 = 200). :)

\frac{200}{300} \ \textless \  \frac{231}{300}

The answer is 0.77 is greater than 4/6. :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

System of equations <br> Y=-1/2x+4 3x-4y=12
Kaylis [27]

Answer:

{x,y} = {8,3}

Step-by-step explanation:

// Solve equation [2] for the variable  y

 [2]    4y = 2x - 4

 [2]    y = x/2 - 1

// Plug this in for variable  y  in equation [1]

  [1]    3x - 4•(x /2-1) = 12

  [1]    x = 8

// Solve equation [1] for the variable  x

  [1]    x = 8

// By now we know this much :

   x = 8

   y = x/2-1

// Use the  x  value to solve for  y

   y = (/2)(8)-1 = 3

The fact that sin(150°) = .5 and sin(-150°) = -.5 implies that the sine function is which type of function?
Naddika [18.5K]
Answer: A) Odd

In general, sin(-x) = -sin(x) for all values of x, so it's an odd function. I don't mean it's a strange function. I mean "odd" in the sense that it's not even (eg: the number 7 is an odd number).
