A rectangle cake has a length of 22 (1)/(2) inches and a width of 15 inches. How many whole, square pieces of cake with side lengths of 2 (1)/(2) inches can be cut from the cake?

54 whole, square pieces of cake can be cut from the cake.

Step-by-step explanation:

Given:

A rectangle cake has a length of and a width of 15 inches.

And the square piece of cake has side lengths

Now, to find the whole square pieces of cake that can be cut from the cake.

So, we find the area of rectangle cake first by using formula:

Length =

Width = 15 inches.

The area of cake is 337.5 square inches.

Then, to get the area of square piece of cake by using formula:

Side =

The area of square piece of cake is 6.25 square inches.

Now, to get the whole square pieces of cake that can be cut from the  cake by dividing the area of cake by the area of square piece of cake:

Therefore, 54 whole, square pieces of cake can be cut from the cake.

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.
