Answer:

x - 7

Step-by-step explanation:

Let's let x = 4 and see which one would be different

x - 7 = 4 - 7 = -3

7 + (-x) = 7 + -4 = 3

-x + 7 = -4 + 7 = 3

7 - x = 7 - 4 =3

As you can see, the top answer would be negative while all the rest are positive. This is because, in that case, the negative sign was attached to the 7 instead of the x.

1/6÷6÷6= please help me with this :D
slava [35]

Answer:

1 / 216

Step-by-step explanation:

Remember, when you divide fractions you have to multiply by the reciprocal

1/6 ÷ 6/1 ÷ 6/1

1st step:  1/6 ÷ 6/1  =  1/6 · 1/6  =   1/36

2nd step:  1/36 ÷ 6/1  = 1/36 · 1/6  = 1 /216

what is the surface area of cone with a diameter of 10 centimeters and a slant height of 12 centimeters round your answer to the
Oduvanchick [21]

The surface area of the cone is 266.9cm^2

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

r=\frac{d}{2} =\frac{10}{2} =5

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

$S A=\pi r^{2}+\pi r l$

Substituting the values, we get,

$S A=(3.14)(5)^{2}+(3.14)(5)(12)$

$S A=(3.14)25+(3.14)(60)$

SA=78.5+188.4

SA=266.9cm^2

Thus, The surface area of the cone is 266.9cm^2

Angle θ lies in the second quadrant, and sin θ = .
nata0808 [166]

Answer:

The coordinate axes divide the plane into four quadrants, labelled first, second, third and fourth as shown. Angles in the third quadrant, for example, lie between 180∘ and 270∘ &By considering the x- and y-coordinates of the point P as it lies in each of the four quadrants, we can identify the sign of each of the trigonometric ratios in a given quadrant. These are summarised in the following diagrams.  &In the module Further trigonometry (Year 10), we saw that we could relate the sine and cosine of an angle in the second, third or fourth quadrant to that of a related angle in the first quadrant. The method is very similar to that outlined in the previous section for angles in the second quadrant.

We will find the trigonometric ratios for the angle 210∘, which lies in the third quadrant. In this quadrant, the sine and cosine ratios are negative and the tangent ratio is positive.

To find the sine and cosine of 210∘, we locate the corresponding point P in the third quadrant. The coordinates of P are (cos210∘,sin210∘). The angle POQ is 30∘ and is called the related angle for 210∘.
