Scientists found the wreck of the titanic 3,797 m below sea level. How many km below sea level is the wreak ?
astraxan [27]

We are given that the titanic is found 3,797 m below sea level. This is simply equivalent to 3.797 km or 3.8 km when rounded off to one decimal.

We should take note that the letter k in km means kilo and a kilo is equivalent to 1000. So this means that for 1 km there is exactly 1000 m. So to convert, simply multiply a value with unit m with this conversion factor. Conversion factor = 1 km / 1000 m

Depth of titanic = 3,797 m (1 km / 1000 m)

<span>Depth of titanic = 3.797 km = 3.8 km</span>

VladimirAG [237]

Answer: Her total savings are equal to $11,000.

Step-by-step explanation:

Hi, to answer this question we have to write an equation.

The total savings (x) multiplied by the percentage in bonds (in decimal form) must be equal to $2,200.

Mathematically speaking:

x (20/100) = 2,200

Solving for x:

x = 2,200/ 0.2

x = $11,000

Her total savings are equal to $11,000.

Feel free to ask for more if needed or if you did not understand something.
