The square pyramid has a volume of 768 cubic inches. The height equals 1/6x and the base is just x. What is the value of x ?

Lunna [17]

The volume for a pyramid is $V= \frac{1}{3} Bh$ , where B is the area of the base and h is the height. We are given the volume, and the base and height in terms of x. Our formula then looks like this: $768= \frac{1}{3} (x)( \frac{1}{6} x)$ . Simplifying the right side we have $768= \frac{1}{18} x^{2}$ . Multiply both sides by 18 to get rid of the fraction and we have $13824= x^{2}$ , so x = 117.575

Jeff has a box containing 26 tiles, each with a different letter of the alphabet. he randomly draws 4 letters, one at a time wit

MArishka [77]

The probability to choose letter n is $\frac{1}{26}$ . After drawing letter n there left 25 letters and the probability to choose the letter w is $\frac{1}{25}$ . After drawing two letters n and w there left 24 letters and then the probability to choose letter b is $\frac{1}{24}$ . After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is $\frac{1}{23}$ .
Using the product rule for probabilities, you can obtain that $P= \frac{1}{26} * \frac{1}{25} * \frac{1}{24}* \frac{1}{23} =0.0000027$ .
