Volume of a cone = PI x r^2 x h/3

Volume = PI x 5^2 x 9/3

Volume = 235.62 cubic cm.

Volume of a block of wax = L x W x H

Volume = 2 x 4 x 3 = 24 cubic cm.

Total number of blocks = Volume of cone / volume of blocks:

235.62 / 24 = 9.82

Round up to 10.

They will need 10 blocks.

a cube has sides with the following number: 3,3,6,9,,7,8. what is the probability of getting a factor of 9 when rolled?

muminat

Answer:

The probability of rolling a factor of 9 is 1/2, or 50%.

Step-by-step explanation:

The number 9's factors are 1, 3, and 9. Three of the six sides of the cube have a factor of 9. Therefore 3/6 of the sides are factors of nine.

Simplify 3/6 to 1/2 to get a probability of 50%.

How do you use compatible numbers to estimate the quotient $595 divided by 25

storchak [24]

Well, 25 certainly doesn't divide evenly into 595, but it does divide into 600, which is very close to 595. So if we divide 600 by 25, we can get a rough estimate of what 595 divided by 25 is.
$\frac{600}{25} = 6* \frac{100}{25} = 6* 4=24$

PLEASE HELP ME!!!!!!!!

Delicious77 [7]

Angle θ between two vectors is given by, $\theta =cos^{-1}( \frac{u
 \cdot v}{|u||v|} )$ ; where $u \cdot 
v=-5(-4)+(-4)(-3)=20+12=32$ ; $|u|= \sqrt{ (-5)^{2} + (-4)^{2} } = 
\sqrt{25+16} = \sqrt{41}$ and $|v|=\sqrt{ (-4)^{2} + (-3)^{2} } = 
\sqrt{16+9} = \sqrt{25}=5$ .
Therefore, $\theta =cos^{-1}( \frac{32}{ 5\sqrt{41}} )=cos^{-1}0.9995=1.8^o$
