pls help!! :P

anonymous · Answer

plug in v, divide by 20, then square

anonymous · Answer

well plug in the value of V and simply solve for t :)

anonymous · Answer

Yep.
$$V = 380 \implies 380 = 20\sqrt{t+237}$$

anonymous · Answer

ohhhh so its just like all the other problems i have been posting wow lol i hate story problems period tho:P

anonymous · Answer

380=20 SQRT t + 273
107=20sqrt t
(107/20)^2=t

Usually each sentence will be giving you an equation or inequality that you can use. Just try to interpret the sentence into an equation, then take all the equations and try to find what they're looking for.
