Answer:
1824
Step-by-step explanation:
200 x (1 + 0.325%)^9 - 1 / 0.325%
200 x (1 + 0.00325)^9 - 1 / 0.00325
200 x 1.00325^9 - 1 / 13/4000
200 x (4013 / 4000)^9 - 1 / 13/4000
200 x 4013^9 / 4000^9 - 1 / 13/4000
200 x 4013^9 - 4000^9 / 4000^9 / 13/4000
200 x 4013^9 - 4000^9 / 13 - 4000^8
4013^9 - 4000^9 / 13 x 20 x 4000^8
4013^9 - 4000^9 / 260 x 4000^8

The correct answer is 2+ because it is last in line when dividing
Answer:
B = 75°
Step-by-step explanation:
Using the Sine rule:
a / sin A = b / sin B = c / Sin C
a / sin A = b / sin B
20 / sin 48 = 26 / sin B
Cross multiply :
Sin B * 20 = sin 48 * 26
Sin B = (sin 48 * 26) / 20
Sin B = 0.9660882
B = sin^-1(0.9660882)
B = 75.036
B = 75°
Pure gold is 24 karats.
14-karat gold is 14/24 pure gold.
2.5 oz * 14/24 = 1.458333... oz
