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

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
