Achange purse contains an equal number of pennies, nickels, and dimes. the total value of the coins is 352 cents. how many coins of each type does the purse contain?

pennies = x

nickel = 5x

dime = 10x

x+5x+10x =352

16x=352

x = 352/16 =22 coins each

check

22x.01 =0.22

22x.05 = 1.10

22 x 0.10 = 2.20

2.20 +1.10 +0.22 =3.52 TRU

22 coins each

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.
