Melissa needs to mix 2 cups of baking soda with 3 cups of vinegar to make a claening solution. How many cups of baking soda are needed for each cup of vinegar?

2/3 cups

Step-by-step explanation:

To find out how many cups of baking soda are needed for each cup of vinegar divide the number of cups of baking soda by the number of cups of vinegar  

2/3 = 0.6666..

Which means you need 2 thirds cups of soda for each cup of vinegar.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

answer: there are 453.592 grams in a pound.
