A)she is not right.because if the remaining peice is the hypotenuse of the triangle, the answer will be around 27.8 if the hypotenuse is 22 then the missing angle is 13.96

b)yes it will work
if you double the measurements of the two sides of a right triangle the other one will be double, too(you can get help from Pythagoras theorem )

c)yes it is possible. if we can double the sides of a right triangle it means that we add measurements to the triangle.
for example:a triangle with sides of 3,4,5
if we add 6,8,10
it will be 9,12,15
hope I could help

The aquarium has 3 more yellow fish than green fish. 60 percent of the fish are yellow. How many green fish are in the aquarium?
cupoosta [38]

The aquarium has 3 more yellow fish than green fish.

60% of the fish are yellow.

To find:

How many green fish are in the aquarium?

Step-by-step explanation:

Let there be x number of fish in the aquarium.

60% of the fish are yellow.

So there are 60x/100 = 3x/5 yellow fish.

Then (100 - 60)% = 40% fish are green.

So there are 40x/100 = 2x/5 green fish.

Given that, there are 3 more yellow fish than green fish

⇒ 3x/5 = 2x/5 + 3

⇒ 3x/5 = (2x + 15)/5

⇒ 3x = 2x + 15

⇒ 3x - 2x = 15

⇒ x = 15

Now, 2x/5 = 2/5 × 15 = 2 × 4 = 6

Answer:

There are 6 green fish in the aquarium.

I need help please! How do i know which is the correct answer.
hichkok12 [17]

Answer:

C

Step-by-step explanation:

since there cant be technically half of someone (i hope not) the domain has to be "whole numbers". hours can be split, so they are "all numbers". well, looking at it again, it is C, since the others can not possibly be correct.
