3 0

Answer:

120 different sub committees are possible.

Step-by-step explanation:

This equals the number of combinations of 3 from 10, 10C3.

10C3 = 10! / 7!3! or we can work it out as 10*9*8 / 3*2*1 = 120.

Log(4)+log(2)-log(5)

Otrada [13]

   log(4) + log(2) - log(5)

   = log(2²) + log(2) - log(5)

   = 2 log(2) + log(2) - log(5)

   = 3 log(2) - log(5)

   = log(2³) - log(5)

   = log (2³/5)

   = log (8/5)

   = log (1.6) = 0.2041... (rounded)

A cylinder has a volume of 390 cm³. If a cone has the same dimensions as the cylinder then what is the volume of the cone.

dangina [55]

Answer: The volume of the cone is 130 cubic centimeters.

Step-by-step explanation:

We know that to find the volume of a cylinder you will use the formula

V= $\pi$ $r^{2} *h$ Where r is the radius and h is the height.

And to find the volume of a cone you will use the formula

V= $\pi$ $r^{2}$ *h /3

So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.

V = 390/3

V = 130 cm^3

- 2x – 117 = = 10x + 59

Alexxx [7]

Answer:

$\huge\boxed{x=-\dfrac{44}{3}=-14\dfrac{2}{3}}$

Step-by-step explanation:

$-2x-117=10x+59\qquad|\text{add 177 to both sides and subtract}\ 10x\ \text{from both sides}\\\\-2x-10x-117+117=10x-10x+59+117\\\\-12x=176\qquad|\text{divide both sides by (-12)}\\\\\dfrac{-12x}{-12}=\dfrac{176}{-12}\\\\x=-\dfrac{176:4}{12:4}\\\\x=-\dfrac{44}{3}$
