Answer:

3a) 1

3b) 2/33

Step-by-step explanation:

3a. $\frac{1}{6}$ ÷ $\frac{1}{6}$

Reverse the 2nd fraction. That way the division sign turns into a multiplication sign.

$\frac{1}{6}$ • $6$

1/6 and 6 cancles out and becomes 1.

$1$

1 is your answer to 3a.

3b. $\frac{3}{9}$ ÷ $\frac{11}{2}$

Reverse the 2nd fraction. That way the division sign turns into a multiplication sign.

$\frac{3}{9}$ • $\frac{2}{11}$

Multiply.

$\frac{6}{99}$

Simplify.

$\frac{2}{33}$

2/33 is the answer to 3b.

I hope this helps!

Respuesta de (-0.5)²

Vladimir79 [104]

Answer:

0.25

Step-by-step explanation:

we have

$(-0.5)^2$

we know that

$-0.5=-\frac{1}{2}$

substitute

$(-\frac{1}{2})^2=(-\frac{1}{2})(-\frac{1}{2})$

Remember that

$(-1)(-1)=1\\(-1)(1)=(-1)$

$(-\frac{1}{2})(-\frac{1}{2})=\frac{1}{4}=0.25$

What are the missing coordinates? My teacher said it was (h-m,n), but I’m saying it is (h+m,n). Could anyone help?

antiseptic1488 [7]

Answer:

<u>You are right, the coordinates are</u>:

$(h+m,n)$

Explanation:

Here is how you can proove that you are right.

Note that m is the x-coordinate of the point $(m,n)$ . Since this point is to the left of the y-axis, it is a negative number, but the negative sign is included in $m$ .

The distance from $(m,n)$ to the y-axis is not $m$ but $-m$ .

That is the same distance from the point with the missing coordinates to the point (h,0).

Then, the missing x-coordinate is $h-(-m)=h+m.$

Of course, there is not doubt about the y-coordinate: it is n, because the point with the missing coordinates is at the same height as (m,n).

Hence, the missing coordinates are x = h+m, and y = n: (h + m, n).
