Design and implement a class called Sphere that contains instance data that represents the sphere's diameter. Define the Sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. Include methods that calculate and return the volume and surface area of the sphere. include a tostring method that returns a one-line description of the sphere. create a driver class called MultiSphere,
whose main method instantiates and updates several sphere objects?

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

the answer should be 3.54 g/cm^3

x=3y-6

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.

the answer is $4.45. i started by figuring out the cost of the plates and napkins. the easiest way to figure this cost out is through the tax. we know the way they found the tax is by multiplying the cost of non-food items by the tax rate (5% or 0.5). so, all we have to do to find the cost before tax is set up an equation and work this formula backwards. the equation is 0.19=0.05x where x is the cost of the plates and napkins. now all you do is divide both sides by 0.05 to come up with 3.8=x. now that we know the cost of the plates and napkins is $3.80, all we have to do is subtract this cost from the total cost of $8.25 giving us the cost of the watermelon which is $4.45.
