The ratio of Country albums to Jazz albums in a music collection is 2:3. If the music collection has 45 albums, how many Country

kap26 [50]

{country albums}:{jazz albums}=2:3
3{country albums} = 2{jazz albums}

{country albums} + {jazz albums} = 45
{jazz albums} = 45 - {country albums}

3{country albums} = 2(45 - {country albums})
3{country albums} = 90 - 2{country albums}
5{country albums} = 90
{country albums} = 18

I got this answer from the link: brainly.com/question/2165977?entry=7190 I give them credit for this, as they were the original. For future reference, you can search your question at the top, and if someone has already answered that question and it is the same as yours, than you can use that, and thank them, etc. I hope this helps!<span />

A heavy metal sphere

GaryK [48]

Answer: the height of the water after the sphere is placed in

it is 33.33 cm

Step-by-step explanation:

The cylinder is called a right circular cylinder because its height make a right angle with its base. The formula for determining the volume of the cylinder is expressed as

Volume = πr^2h

Where

π is a constant whose value is 3.14

r represents the radius of the cylinder.

h represents the height of the cylinder.

From the information given,

r = 10 cm

h = height of water in the cylinder = 20 cm

Volume of water in the cylinder before the sphere was placed in it would be

V = 3.14 × 10^2 × 20 = 6280 cm^3

The formula for determining the volume of the sphere is expressed as

Volume = 4/3 πr^3

V = 4/3 × 3.14 × 10^3 = 4186.67cm^3

Total volume of the sphere and the cylinder = 6280 + 4186.67 = 10466.67 cm^2

To determine the new height of the water,

10466.67 = 3.14 × 10^2× h

h = 10466.67/314 = 33.33 cm

Hurry please !!!

Firdavs [7]

Answer:

The translation corresponds to : $g(x)=\sqrt[3]{x-4}$

which is the first option in your list of possible answers

Step-by-step explanation:

Notice that this new function's graph responds to a horizontal translation to the right of the original graph of $f(x)=\sqrt[3]{x}$ . Notice that the crossing of the x-axis, which for f(x) is at the origin (0, 0), has now moved to the point (4,0), which means a translation to the right in exactly 4 units.

Recall that horizontal translations are performed by subtracting from the independent variable (x) , the number of units you move (in this case 4)

Therefore the new function should look like:

$g(x)=\sqrt[3]{x-4}$
