Which equation could represent "the total cost of bananas at the store that sell for $0.89 per pound" where b is the number of pounds of bananas and C is the total cost?
A. C(b) = 0.89b
B. C(b) = 0.89 + b
C. C(0.89) = b
D. C(b) = 0.89 - b

Equation that represents total cost is C(b) = 0.89b

Step-by-step explanation:

⇒ Total Cost = Number of pounds of bananas × Cost per pound

⇒ C(b) = 0.89b

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°
