23 is the answer 322 divided by 14 is 23
Answer:
Bill is 9.80 km apart from Concert
Step-by-step explanation:
It's given in the question,
m∠B = 75°
m∠C = 45°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
m∠A + 75° + 45° = 180°
m∠A = 180° - 120°
m∠A = 60°
By sine rule,
BC = 
= 9.80 km
Therefore, Bill is 9.80 km apart from Concert.
The answer to the question
The amount in dollars that is in the account after 50 years expressed in power is; 2⁹
<h3>How to apply the rule of exponents?</h3>
We are told that the money doubles in value after every 10 years.
When the account was opened it had 2⁴ dollars in it and after 50 years it has doubled 5 times. The doubling increased by a factor of 2⁵ and is now has a balance of 2⁴ × 2⁵.
Using the rule of exponents, we have;
2⁴ × 2⁵ = 2⁹
