50 people plan to attend the dance and each person will eat 2 slices of cake. if each cake contains 20 slices, how many cakes should you order

5

Step-by-step explanation:

You multiply the number of people by the number of each slices each person gets. Which is 100; 50x2.

Each cake has 20 slices so you divide 100 by 20. Which equals 5.

It would take 5 cakes to feed all 50 people 2 slices each.

Hope this helps. :)

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

150.6

all i did was i multiplied 5.02 by 30
