The constant of proportionality is 34.

The constant of proportionality is 36.

The cost to rent a surfboard for 3 hours is $48.

The cost to rent a surfboard for 5 hours is $90.

answer: i guess 5 units?

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
