Setler79 [48]

Answer:

1675 ft

Step-by-step explanation:

For us to calculate how close the windmill is to the fire, if we imagine it as a triangle, the distance from watch tower to the fire will be:

tan θ= opposite/adjacent

opposite=140 ft

adjacent = x

θ=3°

Thus;

tan 3 = 140/x

x=140/tan 3

x = 2,671.359 ft

Now, the distance from watch tower to windmill will be:

tan θ=opposite/ adjacent

θ=8°

opposite=140 ft

adjacent=y

thus

tan 8 = 140/y

y = 140/tan8

y=996.15 ft

Now, the distance between fire and wind mill will be:

x - y = 2671.359 - 996.15

x - y = 1675.209 ≈ 1675 ft

Answer: Keegan is correct. None of the expressions are equivalent to one another.

The order of operations, PEMDAS, tells us that we do exponents first before addition. This is because the "E" in PEMDAS comes before the "A".

If we wanted to cube all of "6+4", then we would need to say "the quantity 6 plus 4 cubed" or something like "the cube of the sum of 6 and 4".

As the "Model It" sections show, none of the expressions result in the same value. Michael gets 1000, Morgan gets 280, while Keegan gets 70. Therefore, none of the three expressions are equivalent to one another.
