Agroup of three friends order a combo meal which includes two slices of pizza and a drink. each drink is prices at $2.50. if the combined total is 31.50, how much is the cost of a pizza?

$4 per slice

Step-by-step explanation:

D + 2P x 3 = 3D + 6P

2.50 x 3 = 7.50

Drinks = $7.50

31.50 - 7.50 = $24

$24 / 6 = 4

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
