I KNOW THIS ISNT MATH BUT I NEED HELP Often, two or more scientific theories or models are competing with one another to explain the same observations. A scientific theory tends to gain greater acceptance than rival theories when...

...it explains past observations more accurately than rival theories.

...it predicts future observations more accurately than rival theories.

...it is simpler than its rival theories without being less accurate than them.

All of the above.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

ask the math teacher she or he would know lol.

step-by-step explanation:

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7

hope it : ( : )
