1 answer:

8 0

I think the correct answer from the choices listed above is the second option. An equation sometimes has one solution. A system of equation can have one solution when the equations intersect at one point. Equations can also have two or more number of solutions.

Answer:

9 cm.

Step-by-step explanation:

Let the height of the pyramid be h cm, then the height of the cuboid is (15 - h) cm.

Volume of the pyramid:

= 1/3 * h * s^2 where s is the length of a side of the square base.

= hs^2/3 cm^3

Volume of the cuboid:

= s^2(15 - h).

So we have:

hs^2/ 3 = 300.......................(1)

s^2(15 - h) = 600..................(2)

From equation (1) :

h s^2 = 900

s^2 = 900/h

Now substitute for s^2 in equation (2) :

(900/h)(15 - h) = 600

Multiply through by h:

900(15 - h) = 600h

13500 - 900h = 600h

1500h = 13500

h = 9 cm (answer). brainliest?

Is 1/4 the answer to this what ratio forms a porportion with 8/36

Flauer [41]

I don't think so. 1/4 and 8/36. 1 times 8 is 8 but 4 times eight is 32 so it would be 8/32.
