You need to use a ratio of height (H) to shadow length (L) to solve the first problem. It's basically a use of similar triangles, with two perpendicular sides, and with the shadow making the same angle with the vertical.
6 ft = 72 ins, so that rH/L = 72/16 = 9/2 for the player.
So the bleachers are 9/2 x 6 ft = 27 ft.
For the second problem, 9 ft = 108 in, so that the ratio of the actual linear dimensions to the plan's linear dimensions are 9ft/(1/2in) = 2 x 108 = 216.
So the stage will have dimensions 216 times larger than 1.75" by 3".
That would be 31ft 6ins x 54ft.
Live long and prosper.
Answer:

Step-by-step explanation:
The line passes through the origin has an equation y = mx
m - slope
The formula of a slope of a line passes through the origin
and a point (x, y):

We have the point (6, 8). Substitute:

Finally:

The label could be written in the area marked X as "Uses a convex eyepiece lens". Then the correct option is D.
<h3>What are Sets?</h3>
Sets are the collection of well-defined elements. A set is represented by a capital letter symbol and the number of elements in the finite set is shown as curly bracket {..}.
<h3>What is the Venn diagram?</h3>
It is the representation of the sets by the diagram. And shows the condition that is generated between them by the overlapping of the circle.
Shanti began to draw a Venn diagram comparing refracting and reflecting telescopes. The two overlapping circles.
The left circle is labeled Refracting telescopes.
The right circle is labeled Reflecting Telescopes.
An X in the overlap. Both as a label below and outside the overlap.
From the figure, we can say that the label could be written in the area marked X as "Uses a convex eyepiece lens".
Then the correct option is D.
More about the set link is given below.

x²+y²-2x-6y-5=0
x²-2x+y²-6y=5
x²-2x+1+y²-6y+9=5+1+9
(x-1)²+(y-3)²=15
(x-1)²+(y-3)²=(V15)²
-> centre of the circle: C(-1,-3)
-> radius of the circle: V15
Answer:
it is D because it is asking for the opposite of -4 so it would be the tick mark on -4 and 4
