Answer:
30% of $40 would be $12
Step-by-step explanation:
To figure this out you can do cross multiplication. Take 30 over 100 like a fraction (30/100) and then that equals x over 40 (x/40), x being 30% of $40. then you would multiply diagonally. 100 times X and 30 times 40 getting you to 100x = 1200 then isolate the variable so there is no numbers with it, meaning you have to divide both sides by 100. 100x divided by 100= X and 1200 divided by 100= 12. So X=12, meaning 30% of $40 is $12.
Than it would have an answer of 1
Is the answer 44 feet wide? What I did was draw a rectangle an label both widths as 6, that equals 12. Then I subtracted 12 from 96 and got 84 and in order to only get one side length I divided it by 2 and got 42. Next I added 2 to that because the width of one side took up one foot and so did the other side so yeah. I'm just guessing.
Answer:
yes
Step-by-step explanation:
Trinomial means the equation consists of 3 terms therefore 2x+5y+7z is a trinomial.
4/3 * 3.14 * 6^3
4/3 * 3.14 * 216
4/3 * 678.24
904.32
Answer is 904.32
