Answer:
3 1/5 (or 3.5)
Step-by-step explanation:
2(7) - 7(-1)
_______
7 + -1
Next:
14 + 7 (two negatives make a positive)
_____
6
Next:
21/6 which equals 3 1/2 (3.5)
121 over 121 is a whole number of 1
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.
28.34 can be estimated to the nearest number, which is 28. 26.59 can be estimated to the nearest number, which is 27. 33.11 can be estimated to the nearest number, which is 33. 28+27+33=88
Zero if it is talking about it is on the y-axis line
