I think the correct answer from the choices listed above is option C. It is the metal Na that will react with water to produce a metal hydroxide and hydrogen gas. It reacts violently with water forming sodium hydroxide and the hydrogen gas.
Answer:
2
Step-by-step explanation:
A=p (1+r)^t
A=2,000×(1+0.05)^(3)
A=2,315.25
For this case, what we should do is use the given equation.
We have then:
trade discount = rate × list price
Where,
list price = 1000 $
rate = 20 * (1/100) = 0.2
Substituting values we have:
trade discount = (0.2) * (1000)
trade discount = $ 200
Answer:
The amount of the discount is $ 200
The answer is 471 feet.
If A = man to left of balloon
<span>B = balloon </span>
<span>C = man to right of balloon </span>
<span>∠BAC = 75°20' </span>
<span>∠BCA = 49°30' </span>
<span>∠ABC = 180 - 75°20' - 49°30' = 55°10' </span>
<span>AB = 400 ft </span>
<span>Now we have to find the value of x, which is the side opposite to angle of 75°20' </span>
<span>Using Law of Sines: </span>
<span>x/sin(75°20') = 400/sin(55°10') </span>
<span>x = 400 * sin(75°20') / sin(55°10') </span>
<span>x = 471.44 </span>
<span>x = 471 ft </span>
