Answer:
£121
Step-by-step explanation:
5/12 of the total coins = 5/12 x 96 = 40 ⇒ 40 coins are £2 coins
26 of the coins are £1 coins
Number of 50p coins = 96 - 40 - 26 = 30 ⇒ 30 of the coins are 50p coins
Total money collected = 40 x £2 + 26 x £1 + 30 x £0.50 = £121
(rememberinf to convert 50p into £s)
Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°
