Answer:
4
Step-by-step explanation:
You have positive number and it is bigger that negative so your result will be positive too:
7-3=4
$3,611=$4,000
So $4,000 divided by 6 is 666
400 = 8b + y (subtract 8b from each side)
<u>-8b -8b </u>
400 - 8b = y
The answer is y = -8b + 400
i isolated y, which means i left it alone on one side of the equation
Answer:
17.5 meters
Step-by-step explanation
I included an illustration of what they are asking for.
- Notice, since the light of the sun is coming from the same place, the shadow angles relative to the ground, X and Z, will be the same. So the triangles formed are similar
- Use SOH CAH TOA to find the angle Z
- This just means when you have an angle in a right triangle, in order to know whether to use Cosine, Sine or Tangent, look at what sides you have
- We have the sides opposite (O) and adjacent (A) to angle Z, so we tangent (T)
-
- Now since angle Z equals X, they have the same tangent value
- So we can use that to find the building height, which it the opposite (O)
- Don't forget to use the new adjacent 14m
