First put the words in an algebraic format or a model. D = 3.5(√H). Now determine what the question is asking. It's height. Plug in the value of D. Distance is 35 km. 35 = 3.5(√H) We want to get H by itself. First thing to get away from it is 3.5. So divide 35 by 3.5 And 3.5(√h) by 3.5. 10 = √H To get rid of √ do the opposite raise to the power of 2 10² = (√H)² 100 = H You must be 100 kilometers above ground to see 35 kilometers
You could do : Johnny was financing a limited editions Xbox One S. The price was $420 and he put down 40%. How much is left to be financed? dp=420(40/100)=16800/100=168 then you would subtract 420-168 which would give you 252 ;) good luck !!
