A jeweler is dividing

tatuchka [14]

Question:

A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32

Answer:

Option D

Each lot weight $\frac{3}{32}$ part of pound

Solution:

Given that,

A jeweler is dividing 3/8 of a pound of rubies among 4 lots

To find: part of a pound each lot weigh

From given,

$\frac{3}{8} \text{ of a pound } = 4 lots$

Let "x" be the part of a pound each lot weigh

Therefore,

$\frac{3}{8} \text{ of a pound } = 4 lots\\\\"x" part = 1\ lots$

This forms a proportion and solve by cross multiplying

$\frac{3}{8} \times 1 = 4 \times x\\\\x = \frac{3}{32}$

Thus, each lot weight $\frac{3}{32}$ part of pound

Write the equation, in slope-intercept form, of the line passing through the origin and the point $(-4,3)$.

netineya [11]

If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope $m$ . To do that we are going to use the slope formula: $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .
From our two points we can infer that $x_{1}=0$ , $y_{1}=0$ , $x_{2}=-4$ , $y_{2}=3$ . Lets replace those values in the slope formula:
$m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m= \frac{3-0}{-4-0}$
$m= \frac{3}{-4}$
$m=- \frac{3}{4}$

Now that we have our slope, we can use the slope-intercept formula:
$y-y_{1}=m(x-x_{1})$
$y-0=- \frac{3}{4} (x-0)$
$y=- \frac{3}{4} x$

We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is $y=- \frac{3}{4} x$ .
