A water tank in the shape of a rectangular prism has a length of 525 feet, width of 423 feet, and height of 449 feet.
TEA [102]

Answer:

84 cubic feet

Step-by-step explanation:

First, multiply the numbers to get the volume.

5 2/5 * 4 2/3= 25 1/5

25 1/5 * 4 4/9= 112

Then, we can find 3/4 of that.

112*3/4=84.

the area of a right triangle is 336 square centimeters. The base of the right triangle is 48 centimeters. What is the length of
Alex73 [517]

Answer:

50 cm

Step-by-step explanation:

So the first step is to find the height, and to do that you know that the area of a triangle is height * base / 2 =  area. Plugging in the numbers you have, you get:

height*48/2=336

Then, this becomes

height * 24 = 336

Divide both sides by 24

height = 14

Now you can use the base and the height to find the hypotenuse using the Pythagorean Theorem: a^{2} +b^{2} =c^{2}

48^{2} +14^{2} =c^{2} \\2304 + 196 = c^{2}\\2500 = c^2\\50 = c\\c = 50

Therefore the length of the hypotenuse is 50 cm

I need help with all three questions please. I am just Stuck.
vitfil [10]

Answer:

p_{o} = 6, r = 2, p_{12} = 24576.

Step-by-step explanation:

The value of p_{o} is the first value of the geometric series, that is, p_{o} = 6.

If the series represents a geometric sequence, then r must be constant for every consecutive pair of elements, that is:

r_{1} = \frac{p_{1}}{p_{o}} = \frac{12}{6} = 2

r_{2} = \frac{p_{2}}{p_{1}} = \frac{24}{12} = 2

r_{3} = \frac{p_{3}}{p_{2}} = \frac{48}{24} = 2

Since r_{1} = r_{2} = r_{3} = 2, r = 2.

The geometric sequence can be represented by the following formula:

p_{n} = p_{o}\cdot r^{n}, for n \in \mathbb{N}

The 12th element of the geometric sequence is: (p_{o} = 6, r = 2, n = 12)

p_{12} = 6\cdot 2^{12}

p_{12} = 24576
