Answer: Bladder
Step-by-step explanation:
The walls of the bladder contain very few blood vessels and are lined with guanine crystals, which make them impermeable to gases. By adjusting the gas pressurising organ using the gas gland or oval window the fish can obtain neutral buoyancy and ascend and descend to a large range of depths.
Answer:
The answer to your question is x = 17.32; y = 8.67
Step-by-step explanation:
Process
1.- Use trigonometric functions to find x and y
a) sin Ф =
Ф = 60°
opposite side = 15
hypotenuse = ?

∠TAB = x°
∠TAC = 90°
(Angle between tangent and radius)

∠CAB = a = 90 - x
∠CBA = 90°
(Angle in a semi circle)
∠ACB = 180 - 90 - a (3ʳᵈ angle of triangle)

Answer:
12 inches
Step-by-step explanation:
You can use proportions to solve this:
1/10 = x/120
Cross multiply:
12 = x
Answer:
A. $35+$0.89r=$75
Explanation:
It’s only $35 to get in, you don’t have to pay an extra $35 for anything, however, the $0.89 is changeable, that’s were the variable comes in. If you go on more rides you would multiply every ride with how much it costs. The last number is how much you spend (total)
