That is true. Let's say there are 100 fish. If half the fish are zebra danios then there are 50 zebra danios fish. If there are 50 fish left, and there are 2 times as many catfish as there are fancy guppies, then 33.33 of them are catfish and 16.66 of them are fancy guppies. Since one third of 100 is 33.33, then 1/3 of the fish are catfish.

Answer:
15.30 feet
Step-by-step explanation:
The ladder creates a right triangle with the wall and the ground. Because sine is the opposite divided the hypotenuse:
where x is the wall height that the ladder reaches.
Multiply both sides by 16 we get:
Using the calculator, we can get 15.30
17.16 is 62.4% of what number?
'is' indicates an equal sign.
62.4% = 0.624
'of' indicates multiplication
'what number' indicates an unknown value that we can call 'x'
17.16 = 0.624 * x
17.16 = 0.624x
Divide 0.624 to both sides:
x = 27.5
