Notice how the problem states that the marbles are being placed back into the bag which means you are on the right track but the denominators are the same.

3/11 times 3/11 times 5/11 which gives us the answer of 45/1131

A circle is centered about the point (2, 0). The point (0, 1) is on the circle. Which statement proves that the point (4, 1) is
mestny [16]

Answer:

Step-by-step explanation:

the circle is at the origin and (0,4) is a point on the circle then the radius of the circle is:

r^2=0^2+4^2

r^2=16

r=4

so we can check that the other point is four units from the origin and thus also on the circle...

d^2=2^2+6^2

d^2=4+36

d^2=40

since d^2>r^2, (2,6) is outside the circle

The sun is directly overhead. The shadow of the balloon falls
Mariana [72]

The height of the ballon is 34 feet 2 inches.

To be able to solve this question, we need to understand the concept of angle of elevation.

<h3>What is the angle of elevation?</h3>

An angle of elevation is the angle formed between the horizontal plane (adjacent line) to the line of sight(elevation) from the viewer's eye to the object located in the space.

  • The diagrammatic expression for the question given can be seen in the image attached below.

From the image below, we can determine the height of the ballon by taking the tangential trigonometric function.

\mathbf{tan \theta = \dfrac{opposite}{adjacent}}

\mathbf{tan \ 67= \dfrac{x}{14 ft \ 3 in }}

Let's first convert 14 ft 6 in to ft, by doing so, we get 14.5 ft

\mathbf{tan \ 67= \dfrac{x}{14.5\ ft }}

x = tan 67 (14.5 ft)

x = 2.356(14.5 ft)

x =34.162 ft

To ft and inches, we have:

x = 34 ft 2 inches
