The circled one is what I need help with, thank you :)

You have to first do pythagorean theorem. 1.25 squared (1.25 came from dividing 2.5 by 2) plus x squared = 4 squared. once you find x, use volume formula which is v= 1/3 base times height (: hope this helped!!!

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
