Jonah collects rainwater in a large barrel that weighs 30 pounds. when there are 10 gallons of water in the barrel, the total weight of the barrel and the water is 113.4 pounds. when there are 20 gallons of water, the total weight is 196.8 pounds. which equation and graph match this situation? a. y = 8.34x + 30 b. y = 30x + 8.34 c. y = 30x + 8.34 d. y = 8.34x + 30

How do i do this activity, is appreciated

Give me the equations of two lines that have the same slope but are not parallel.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
