$Question$

what is 7.69/43.685=?

Answer:

The Correct Answer is 5.6 :)

Step-by-step explanation:

Change the divisor 7.69 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

4368.5 ÷ 769 = 5.6

and therefore:

43.685 ÷ 7.69 = 5.6

Both calculated to 1 decimal places.

Complete the identity

spin [16.1K]

Answer: $cos(\pi-x)=-cos(x)$

Step-by-step explanation:

We need to apply the following identity:

$cos(A - B) = cos A*cos B + sinA*sin B$

Then, applying this, you know that for $cos(\pi-x)$ :

$cos(\pi-x)=cos(\pi)*cos(x)+sin(\pi)*sin(x)$

We need to remember that:

$cos(\pi)=-1$ and $sin(\pi)=0$

Therefore, we need to substitute these values into $cos(\pi-x)=cos(\pi)*cos(x)+sin(\pi)*sin(x)$ .

Then, you get:

$cos(\pi-x)=(-1)*cos(x)+0*sin(x)$

$cos(\pi-x)=-1cos(x)+0$

$cos(\pi-x)=-cos(x)$

Change 0.275 to a fraction

goldenfox [79]

Well, the number is decimal form, is in the thousandths place, so the denominator, would be 1000's:
0.275 = 275⁄1000 
Then, you have to Simplify 275⁄1000 In which, you would get:  11⁄40
