Write 0.614¯¯¯ as a fraction in simplest form.
Verizon [17]

Answer:

307/500

Step-by-step explanation:

307 is a prime number.

The way to find this out is to take 0.614 and multiply it by 1,000 because then it will be a natural number. 0.614*1,000=614.

now you take 614/1,000 because that's what you multiplied it by and simplify it.

614/2 and 1,000/2=307/500 and this cannot be simplified any more than this because 307 is a prime number.

2.8 = 2y<br> What does y equal?<br> 1.4<br> 0.5<br> 2.8<br> 0.6
igor_vitrenko [27]

Answer: 1.4

Step-by-step explanation: First, swap the sides of the equation so that the one with the variable can be in front.

So, its 2y=2.8

To solve this, you simply divide both sides of the equation by 2.

2 divided by 2 is 0. That leaves you with the y by itself. Then, 2.8 divided by 2 is 1.4

So, y=1.4

inn [45]
<h2><u>Answer:</u></h2>

y = cos ^- 1 (x)

Step-by-step explanation:

The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].
