Answer: 24.49 or 24.5 if rounded.

Step-by-step explanation: We have to use the pythagorean theorem of course...

a² + b² = c²

15² + 20² = c²

225 + 400 = c²

600 = c²

$\sqrt{600}$

c = 24.49 (If we round to the nearest tenth then the answer is 24.5)

Answer:

Step-by-step explanation: No, Gavin is not correct because 284.42 is less than 400 the equation is 200(1+0.09/2)^8 when solved you get 284.42 which is not enough.

Step-by-step explanation:

simplifying this

Ok so do 0.09/2 which is 0.045 then add 1 so you get 200•1.045^8 then you do 1.045^8= 1.422100.... so I did 1.422100•200 to get the final answer of 284.42

HEEEELP!!!!!!: An icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 120 mm. The icicle drips at

OleMash [197]

Find the volume of the icicle using the formula V = PI x r^2 x h/3

Volume = 3.14 x 4.5^2 x 120/3

Volume = 3.14 x 20.25 x 40

Volume = 2543.4 cubic mm.

Now divide the total volume by the drip rate:

2543.4 / 75 = 33.9 minutes.

The answer is D.
