K = 4a+9ab
k = a(4+9b)
k/(4+9b) = a
a = k/(4+9b)

None of the answer choices match what I got, so I'm thinking there's a typo. Perhaps choice A is supposed to say a = k/(4+9b) since that seems like the closest

The mass of a piece of iron pyrite, or "fools gold", is 57.2 g. The volume is 11 cm3. What is the density of the piece of iron p

katen-ka-za [31]

Answer:

Step-by-step explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question we have

$density = \frac{57.2}{11} = 5.2 \\$

We have the final answer as

Given that ΔABC and ΔA'B'C' are similar right triangles that share the same slope, m, on the coordinate plane. Find the equation

Oksana_A [137]

Answer:

$y=\frac{2}{3}x$

Step-by-step explanation:

The similar triangles are drawn in the figure attached.

As shown in the figure, the smaller triangle ΔABC, and the larger triangle ΔA'B'C' share the same slope; therefore, the slope of the hypotenuse is the length of the triangle ΔA'B'C' divided by its base:

$m=\dfrac{rise}{run} =\dfrac{height}{base}= \dfrac{4}{6}=\dfrac{2}{3} \\\\ \boxed{m= \frac{2}{3}}$

Therefore, the equation of the hypotenuse is

$\boxed{y=\dfrac{2}{3} x}$
