3²×7................................................
Answer:
£289.20
Step-by-step explanation:
13:2 = x:16 or 13/2 = x/16
cross multiply: 208 = 2x
simplify: x = 104
16 blue tiles x £2.80 each = £44.80
104 white tiles x £2.35 each = £244.40
44.80 + 244.40 = £289.20
Answer:
2000 mm^3* .0005oz/1mm^3=1oz
Step-by-step explanation:
v=40mm*25mm*2mm=2000mm^3
If the perimeter is 182, double the length which is 52 to get 104. Subtract that from 182 to get 78. Divide that by 2 to get the width which is 39.
This means that 3/10 are red and that 7/10 are red, so 7/10(80) = 56blue marbles and 3/10(80)= 24red marbles
