Whatever% of anything is just (whatever/100) * anything.
since we know inflation is 3.7%, what is 3.7% of 1.69?
well is just (3.7/100) * 1.69.
that's how much the quart of oil costs more now. So simply add that to 1.69.
Because 1/4 is a fractional number, it is also a ratio which means it is Rational. :)
Well, Brainly really doesn't like questions that are lifted straight out of exams, tests, or quizzes, so there's only so much I can say.
... You've GOT the formula for the height h at any time t .
... It TELLS you to find t when h=0.
... So write the equation
-16 t^2 + 32 t = 0
and then solve the equation to find t .
You'll find two solutions for t .
One of them is. t=0 .
This reveals the mind-blowing fact that the instant before the rocket was launched, at t=0, the rocket was on the ground.
The other solution for t will tell you how many seconds after launch the rocket is back on the ground.
there's no exact answer for it because pi goes on forever
