Please help (question in picture) Also need help in part D:
Emma notices that since her credit card balance compounds monthly, she is charged more than 15% of her initial loan amount interest each year. She wants to know how much she would actually pay if the card were compounded annually at a rate of 15%. Which expression could Emma use to evaluate her balance with an annual compounding interest rate?

A. 300(1.15)^t
B. 300(1.0125)^t
C.300(1.015)^12t
D.300(1.15)^12t

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

step-by-step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

step-by-step explanation:

the true ones are a b and d
