It takes machine A x hours to manufacture a deck of cards that machine B can manufacture in y hours. If machine A operates alone

nlexa [21]

Answer:

The expression that shows how long the two machines will operate simultaneously is:

$\frac{y(100x-z)}{x+y}$

Step-by-step explanation:

We know that:

x: hours to manufacture a deck of cards for machine A

y: hours to manufacture a deck of cards for machine B

z: hours that machine A operates alone

The number of decks manufactured only by machine A is:

$\frac{z}{x}$

So, the remaining decks are given by:

$100-\frac{z}{x}=\frac{100x-z}{x}$

Then, the combined rate of machines A and B would be:

$\frac{1}{x} +\frac{1}{y} =\frac{x+y}{xy}$

The work-rate formula is:

$Amount= Rate \times Time$

Hence, the time that the two machines work simultaneously is:

$Time=\frac{Amount}{Rate}$

$Time=\frac{Amount}{Rate} =\frac{\frac{100x-z}{x} }{\frac{x+y}{xy} } ={\frac{100x-z}{x} \times \frac{xy}{x+y}=\frac{y(100x-z)}{x+y}$

Answer:

16.93 m

Step-by-step explanation:

The triangle for the given scenario is shown below.

From the triangles $\Delta ABC$ and $\Delta ABD$ ,

AB is the pole height, BC or BD is the distance of either of the wire guys from the foot of pole, and $\angle C$ or $\angle D$ is the angle that each either of the guys make with the top of pole.

Let the distance of either of the wire guys from the foot of pole be $x$ .

Now, consider $\Delta ABC$ .

Given: AB = 9 m, BC = $x$ , and $\angle C=28$ °.

Using tan ratio of the angle C, we get

$\tan (\angle C)=\frac{AB}{BC}\\\tan (28)=\frac{9}{x}\\x=\frac{9}{\tan (28)}=16.93$

Therefore, 16.93 m away from the foot of the pole are the guys anchored.
