A navy cruiser detects a nuclear submarine that is 2500 feet from the cruiser. The angle between the water level and the submarine is 15.5 degrees. How deep is the submarine?
Answers
Answer:
Depth of the submarine = 668.09 feet
Step-by-step explanation:
From the figure attached,
In triangle ABC,
Distance between a navy cruiser and a nuclear submarine = 2500 feet
Angle between the water level and the submarine = 15.5°
By applying sine rule in the given triangle,
sin(∠BAC)° = [tex]\frac{BC}{AC}[/tex]
sin(15.5°) = [tex]\frac{BC}{2500}[/tex]
BC = 2500[sin(15.5)]
BC = 668.09 feet
Therefore, submarine is 668.09 feet deep in the sea.

Based on the information, the value of the piano after 16 years is $140.74.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Using this formula to find the value of the piano, v, after t years.
CP = Principal(1-rate)[tex]^t[/tex]
Where:
Principal=$5,000
Rate=20%
Number of year = 16 years
Let plug in the formula;
=5,000(1-0.20)^16
=5,000(.80)^16
=$140.737
= $140.74 (Approximately)
Hence, the value of the piano after 16 years is; $140.74.

Step One: Divide both sides by 2
Step Two: Add 3 to both sides
Step Three: Multiply both sides by 1/6
Step-by-step explanation:
For step one, we can see that half of 12 is 6, half of 6 is 3 and half of 10 is 5.
For step two, we add 3 to the left to cancel out the -3 and add 3 to the left to make 8.
By process of elimination, we can see that C matches up to step 3.

Answer: B.
Step-by-step explanation:
Suppose you have a L.L. Bean coupon of $63.60 and you want to know the final or sale price if the discount is 20 percent.
Using the formula (b) and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 63.60 - 12.72
Sale Price = $50.88 (answer).
This means the cost of the item to you is $50.88.
You will pay $50.88 for a item with original price of $63.60 when discounted 20%.
In this example, if you buy an item at $63.60 with 20% discount, you will pay 63.60 - 12.72 = 50.88 dollars.
Answer: $50.88
Step-by-step explanation:
Step 1: Find 20% of 63.60
20% of 63.60
20% = 20/100 = 0.2
0.2 × 63.60 = 12.72
20% of 63.60 is removed to get the selling price.
Step 2: Subtract
20% of 63.60 = 12.72
63.60 - 12.72 = 50.88
The selling price is $50.88.
