Answer:
105.46 feet
Step-by-step explanation:
We know all three angles (60, 90, and 30), as well as one side, which is adjacent to the 60 degrees. We want to find the side opposite to the 60 degree angle. To do this, we can use tangent, utilizing both opposite and adjacent.
Using tan, we can say that tan(60) = x/58, with x representing the height of the lighthouse (minus 5, because Santos is 5 feet tall and he is measuring the angle from the top of his head). Multiplying both sides by 58, we can get that 58 *tan(60) = x = 100.46. Add 5 to that to get 105.46 feet as your answer.
#2) 435+25x=875-15x
40x=440
x=11
the answer is 11 weeks.
#3) 2500(3x) for x=10
2500(3*10)
2500(30)
7500
the answer is 7500 bacteria after 10 months.
I believe the slope will be 8/5
Answer:
The answer to your question is k = 
Step-by-step explanation:
Equation
5 - vk = k
Process
1.- Add vk in both sides
5 - vk + vk = k + vk
2.- Simplification
5 = k + vk
3.- Factor k (like terms)
5 = k(1 + v)
4.- Divide both sides by "1 + v"
5 / (1 + v) = k(1 + v) / (1 + v)
5.- Simplify
5 / (1 + v) = K
