A conical container can hold 120π cubic centimeters of water. The diameter of the base of the container is 12 centimeters.

nignag [31]

Answer:

A. 10cm

B. 8 times

Step-by-step explanation:

The question is on volume of a conical container

Volume of a cone= $\pi r^{2} h/3$

where r is the radius of base and h is the height of the cone

Given diameter= 12 cm, thus radius r=12/2 =6 cm

$v=\pi r^2h/3 \\120\pi =\pi *6*6*h/3\\120\pi =12\pi h\\10=h$

h=10 cm

If height and diameter were doubled

New height = 2×10 =20 cm

New diameter = 2×12 = 24, r=12 cm

volume = $v=\pi r^2h/3\\v=\pi *12*12*20/3\\v=960\pi$

To find the number of times we divide new volume with the old volume

$N= 960\pi /120\pi \\\\N= 8$

Karla has spent $48 on food. she bought milk cheese and meat. the milk cost half as much as the cheese and the meat cost half as

skelet666 [1.2K]

C = cheese

milk is half of cheese....so milk costs 0.5c
meat is 4 times as much as cheese...so meat costs 4c
and $ 48 was spent

so ur equation would be : c + 0.5c + 4c = 48 <=

Given the function f(x)=3x-5, for which value in the domain does f(x)=-38?

victus00 [196]

$f(x) = -38\\\\\implies 3x -5 = -38\\\\\implies 3x = -38 +5 \\\\\implies 3x = -33\\\\\implies x = -\dfrac{33}{3}\\\\\implies x = -11$
