The Mississippi River flows at 16,790 cubic meters per second.

Olenka [21]

Answer:

Time taken is $1.45\times 10^8\textrm{ s}$ .

Step-by-step explanation:

Given:

Volume of Gulf of Mexico, $V=2434000000000000=2.434\times 10^{12}\textrm{ }m^3$

Flow rate of the Mississippi River, $f=16790=1.679\times 10^4\textrm{ }m^{3}/s$

Now, time taken to fill the volume of Gulf of Mexico is given as:

$Time=\frac{\textrm{Total volume}}{\textrm{Flow rate}}\\\\Time=\frac{2.434\times 10^{12}}{1.679\times 10^{4}}=1.45\times 10^{8}\textrm{ s}$ .

Therefore, the time by the Mississippi River to fill the volume of the Gulf of Mexico is $1.45\times 10^8\textrm{ s}$ .

How do I go about solving this.

notka56 [123]

<h2>Answer:</h2><h2>x=37.5° and angle ABC is 52.5°</h2><h2>Step-by-step explanation:</h2>

We know that angle CBD is a right angle.

We also know that angle ABE is 180°.

Our unknown angle values are angle DBE and angle CBA.

angle CBD minus angle ABE will be 90°.

angle ABC plus angle DBE must equal 90°.

Solving for x:

(x+15)+(x)=90°

(x+15-15)+(x)=90°-15

(x)+(x)=75°

2x=75°

2x/2=75°/2

x=37.5°

Checking the work:

ABC=37.5°+15=52.5°

CBD=90°

DBE=37.5°

In conclusion, ABC plus CBD plus DBE equals 180°
