Answer:

Step-by-step explanation:

The ratio of boys to girls is 12 to 16, 12:16 or 12/16 (all different ways this can be written). The fraction form 12/16 can be reduced by dividing by the greatest common factor. Both 12 and 16 are divisible by 4, so the reduced fraction is 12/4 over 16/4 = 3/4. In other words, there are 3 boys for every 4 girls in the class.

If the radius of a right circular cylinder is doubled and height becomes 1/4 of the original height, then find the ratio of the

Oduvanchick [21]

Given info:-If the radius of a right circular cylinder is doubled and height becomes 1/4 of the original height.

Find the ratio of the Curved Surface Areas of the new cylinder to that of the original cylinder ?

Explanation:-

Let the radius of the right circular cylinder be r units

Let the radius of the right circular cylinder be h units

Curved Surface Area of the original right circular cylinder = 2πrh sq.units ----(i)

If the radius of the right circular cylinder is doubled then the radius of the new cylinder = 2r units

The height of the new right circular cylinder

= (1/4)×h units

⇛ h/4 units

Curved Surface Area of the new cylinder

= 2π(2r)(h/4) sq.units

⇛ 4πrh/4 sq.units

⇛ πrh sq.units --------(ii)

The ratio of the Curved Surface Areas of the new cylinder to that of the original cylinder

⇛ πrh : 2πrh

⇛ πrh / 2πrh

⇛ 1/2

⇛ 1:2

Therefore the ratio = 1:2

The ratio of the Curved Surface Areas of the new cylinder to that of the original cylinder is 1:2

Leona [35]

Answer:

Part A: The total is 57.58

Part B: 19.19 each

Step-by-step explanation:

Part A: 15(3) +3.50(3)=55.50

55.50 plus the 3.75% tip (not really addition i dont know how to find a percentage so i looked that part up) but it come out to $57.58

Part B: 57.58 divided by 3 is $19.19 ( I do 3 because Maria and 2 more friends)

Hope it helps and that it is 100% correct dont come at me if something is wrong with my math
