Answer:
n = 24
Step-by-step explanation:
Multiply the given equation by the product of denominators. Then subtract 6n and go from there.
_____
<em>Alternate solution</em>
Any proportion can be written 4 ways. If we write this one "sideways," we have ...
6/8 = (n -6)/n
1 -1/4 = 1 -6/n . . . . . expand in parallel fashion
6/n = 1/4 . . . . . . . . subtract 1, multiply by -1
n = 24 . . . . . . . . . multiply by 4n
__
<em>Another alternate solution (can be done mentally)</em>
The above "sideways" proportion can be reduced to ...
3/4 = (n -6)/n
The difference between values on the left is 1 unit. On the right, the difference between values is 6. (The numerator is 6 less than the denominator.) The denominator on the left (4) is 4 times the difference, so the denominator on the right (n) will likewise be 4 times the difference: n = 4·6 = 24. Check: 3/4 = 18/24.
Let the distance of the engineer from the base of the building be x, then
tan 22 = 450/x
x = 450/tan 22 = 450/0.4040 = 1,113.79
Therefore, the distance of the engineer from the base of the building to the nearest foot is 1,114 feet.
Answer:
A) x = -3
Step-by-step explanation:
|3(-3) + 9| = 0
|-9 + 9| = 0
|0| = 0
0 = 0
