2/-3 divided by -1 2/7 = pls explain the answer

katen-ka-za [31]

Answer:

$\frac{14}{27}$

Step-by-step explanation:

$-1\frac{2}{7} = -\frac{9}{7}$
Plug -9/7 in: $-\frac{2}{3}$ ÷ $-\frac{9}{7}$
-2/3 ÷ -9/7 = 2/3 ÷ 9/7 = 2/3 × 7/9
$\frac{2}{3}$ × $\frac{7}{9} = \frac{14}{27}$

I hope this helps!

Factorize 9/16 x2 + xy + 4/9 y2

miskamm [114]

$\frac{9}{16} x^2 + xy + \frac{4}{9} y^2 = (\frac{3}{4} x)^{2} + xy + (\frac{2}{3}y)^{2} = (\frac{3}{4} x)^{2} + 2* \frac{3}{4} x * \frac{2}{3}y + (\frac{2}{3}y)^{2}$ $= ( \frac{3}{4}x + \frac{2}{3} y)^{2}$

What is the measure of? angle PQR [Not drawn to scale) -51 -55 -74 -78

soldi70 [24.7K]

Given:

The exterior angle P is 74°

The measure of ∠PRQ is 51°

We need to determine the measure of ∠PQR

Measure of ∠QPR:

From the figure, it is obvious that P is the intersection of the two lines.

The angle 74° and ∠QPR are vertically opposite angles.

Since, vertically opposite angles are always equal, then the measure of ∠QPR is 74°

Thus, the measure of ∠QPR is 74°

Measure of ∠PQR:

The measure of ∠PQR can be determined using the triangle sum property.

Thus, we have;

$\angle PQR+\angle QPR+\angle PRQ=180^{\circ}$

Substituting the values, we get;

$\angle PQR+74^{\circ}+51^{\circ}=180^{\circ}$

$\angle PQR+125^{\circ}=180^{\circ}$

$\angle PQR=55^{\circ}$

Thus, the measure of ∠PQR is 55°

Hence, Option B is the correct answer.
