the volume of a pyramid whose base is aright triangle is 234 units. If the two legs of the right triangle measures 9 units and 1

Kobotan [32]

If the volume of this pyramid is 234 units, the height of the pyramid is equal to 13 units.

<h3>How to calculate the volume of a pyramid.</h3>

Mathematically, the volume of a pyramid is given by the formula:

$Volume = \frac{1}{3} \times base\;area \times height$

For the base area:

The area of a right triangle is given by:

$A=\frac{ab}{2} \\\\A=\frac{9 \times 12}{2} \\\\A=\frac{108}{2}$

A = 54 square units.

Given the following data:

Volume of a pyramid = 234 units.

Side lengths of right triangle = 9 and 12 units.

Now, we can calculate the height of the pyramid:

$234 = \frac{1}{3} \times 54 \times height\\\\234=18h\\\\h=\frac{234}{18}$

h = 13 units.

8o + 12p = 382 12o + 8p = 388 What does p equal?

shutvik [7]

For this case we have a system of two equations with two variables:

Clear "o" from the first equation:

$8o = 382-12p\\o = \frac {382-12p} {8} = \frac {191-6p} {4}$

We substitute in the second equation:

$12 (\frac {191-6p} {4}) + 8p = 388\\3 (191-6p) + 8p = 388\\573-18p + 8p = 388\\-10p = 388-573\\-10p = -185\\p = \frac {185} {10}\\p = 18.5$

ANswer:

$p = 18.5$

PLEASE HELP ME RN I WILL MARK THE BEST ANSWERS BRAINLEAST AND MARK 5 ANSWER THE ONES U KNOW NOOOO EXPLAINTION NEEDED

Novosadov [1.4K]

For the first question, the answer is 25/14.

Because 14x = 25y Which means x must equal more than y. And 25/14 is the only answer like this.

For the second question, the answer is 30 x 18.

30/5 = 6 18/3 = 6 18 + 18 + 30 + 30 = 96

So, both the perimeter and the ratio is correct with this answer.

For the third question, the first answer is correct.

x < -4 and only a negative number can be less than another negative. Also, the negative must have a higher value to be less than another negative.

For the last question, the last answer is correct. no explanation for this one, it would take too long ;)
