Answer:

4\sqrt{3}/3

Step-by-step explanation:

tan 30 = \sqrt{3} /3

cos 30 = \sqrt{3}/2

sin 60 = \sqrt{3}/2

=> Total = \sqrt{3} /3 + \sqrt{3}/2 x 2 = 4\sqrt{3}/3

Answer:

\sqrt{3} + \frac{5\sqrt{3} }{6}

Step-by-step explanation:

tan(30°) = \frac{\sqrt{3}}{3}

cot(30°) = \sqrt{3}

sin(60°) = \frac{\sqrt{3}}{2}

\frac{\sqrt{3} }{3} +\sqrt{3} +\frac{\sqrt{3}}{2}  = \sqrt{3} +\frac{5\sqrt{3} }{6}

A seal went 25 feet below sea level to catch a fish. A sea lion dove 10 feet less than three times as deep as the seal to catch
vfiekz [6]

Answer:

65 feet below sea level.

Step-by-step explanation:

With the information provided, we can create the following equation for the position of the sea lion (p)

p = 3x - 10

In this equation, x would be the final position of the seal when it caught the fish. Since we are told that the seal's position is 25 feet below sea level then we can plug in this value as x and solve for p...

p = (3 * 25) - 10

p = 75 - 10

p = 65

Finally, we can see that the sea lion's position is 65 feet below sea level.

Round 713,949 to the nearest hundred
TEA [102]

Answer:

<em>713,900</em>

Step-by-step explanation:

713,<u><em>9</em></u>49

The bold, italic, underlined digit is the hundreds digit.

To round to the nearest hundred, change all digits to the right of the hundreds digit to 0. Now you have

713,900

There is one more step. Look at the first digit that used to be to the right of the hundreds digit. If it is from 1 to 4, the hundreds digit remains the same. If it is from 5 to 9, the hundreds digit goes up by 1. In this case, the first digit to the right of the hundreds digit was 4, so the hundreds digit does not go up by 1.
