Ahippopotamus can stay under water for 15 minutes. a sea cow can stay under water y minutes. this is 11 minutes longer than one-third the time a hippopotamus can. write an equation and solve to determine how long the sea cow can stay under water.

The sea cow can stay under water for 16 minutes.

Step-by-step explanation:

A hippopotamus can stay under water for 15 minutes.

A sea cow can stay under water minutes and this is 11 minutes longer than one-third the time a hippopotamus can.

So, "11 minutes longer than one-third the time a hippopotamus can" means:  

Thus, the equation will be:  

Now, solving the above equation, we will get.........

So, the sea cow can stay under water for 16 minutes.

i think it’s a i believe

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
