A camera company routinely ships cameras that have 4 defective cameras for every 800 shipped. Bradley works at a photo shop that
garri49 [273]
From the information in the problem, the ratio of defective cameras to cameras shipped is \frac{4}{800}. Reducing this ratio, we get the simplified form of

\frac{4}{800}\div \frac{4}{4}= \frac{1}{200}

which, incidentally, gives us our answer. We have 1 defective camera for every 200 cameras shipped.

The variable $x$ varies directly as the square of $y$, and $y$ varies directly as the cube of $z$. If $x$ equals $-16$ when $z$
Kisachek [45]

If x varies directly as y^2, then there is some constant a for which

x=ay^2

Similarly, there is some constant b such that

y=bz^3

Given that x=-16 when z=2, we have

\begin{cases}-16=ay^2\\y=8b\end{cases}\implies-16=a(8b)^2\implies ab^2=-\dfrac14

Now when z=\frac12, we get

\begin{cases}x=ay^2\\y=\frac b8\end{cases}\implies x=a\left(\dfrac b8\right)^2=\dfrac{ab^2}{64}=\dfrac{-\frac14}{64}=\boxed{-\dfrac1{256}}

It costs $3.45 to buy 3/4 lb of chopped walnuts. How much would it cost to purchase 12 lbs of walnuts? Enter the numeric value o
mote1985 [20]

Answer:

$55.20

Step-by-step explanation:

Create a proportion where x is the cost of 12 lbs of walnuts:

\frac{3.45}{0.75} = \frac{x}{12}

Cross multiply and solve for x:

0.75x = 41.4

x = 55.2

So, for 12 lbs of walnuts, it will cost $55.20
