How do I solve this question?
Oduvanchick [21]

9514 1404 393

Answer:

  no, y does not vary directly with x

Step-by-step explanation:

If there is direct variation, the constant of variation can be found as ...

  k = y/x

Here, those ratios are ...

  y/x = 6/3 = 2

  y/x = 18/6 = 3

  y/x = 24/8 = 3

The ratio of y to x is NOT A CONSTANT, so <em>there is no direct variation.</em>

The sun shines at a 30° angle to the ground. To the nearest inch, how long is the shadow cast by a 72-inch tall fence post?
Mars2501 [29]

Answer:

The shadow length is 125 inches.

Step-by-step explanation:

The triangle that the sun's rays and the fence post form is shown in the figure.

From trigonometry we know that tan(30^o) is the ratio of the opposite <em>(72-in fence)</em> to the adjacent side L of the triangle <em>(the shadow length): </em>

<em />tan(30^o) = \dfrac{72 in}{L}<em />

since

<em />tan(30^o) = \dfrac{\sqrt{3} }{3}<em />

we have

<em />\dfrac{\sqrt{3} }{3}  = \dfrac{72 in}{L}<em />

solving for L we get:

L = 72\sqrt{3}\\\\\boxed{L = 124.71\: in.}

Hence, the length of the shadow to the nearest inch is 125 inches.

tatiyna

Answer:

the number of hours taken is 2

Step-by-step explanation:

The computation of the number of hours taken is shown below:

As we know that

Distance = travel time × speed

The Guillermo to catch Dorabella be t = T

So the equations would be

9T = 4 + 7T

9T - 7T = 4

2T = 4

T = 2 hours

hence, the number of hours taken is 2
