Evaluation_Word_Problems/593954: I need help setting this equation up, I keep getting a neagtive number.. One taxi cab charges $2.00 plus 75 cents per mile while a second taxi charges 75 cents plus 80 cents per mile. For what length trip would the fee charge by each taxi be the same? 1 solutions Answer 376583 by ankor@dixie-net.com(15652)   on 2012-04-01 12:20:48 (Show Source): You can put this solution on YOUR website! One taxi cab charges $2.00 plus 75 cents per mile while a second taxi charges 75 cents plus 80 cents per mile. For what length trip would the fee charge by each taxi be the same? : Not sure how you would get a negative, but lets do it this way : Let d = trip distance that both cabs would cost the same : 2nd cab cost = 1st cab cost .80d + .75 = .75d + 2.00 .80d - .75d = 2.00 - .75 .05d = 1.25 d = 1.25/.05 d = 25 miles : : See if this is true, find the cost for each at 25 mi .80(25) + .75 = $20.75 .75(25) + 2.00 = 20.75

Quadratic_Equations/593595: If a stone is tossed from the top of a 230 meter building, the height of the stone as a function of time is given by h(t) = -9.8t^2 – 10t + 230, where t is in seconds, and height is in meters. After how many seconds will the stone hit the ground? Round to the nearest hundredth’s place; include units in your answer. 1 solutions Answer 376533 by ankor@dixie-net.com(15652)   on 2012-03-31 21:50:39 (Show Source): You can put this solution on YOUR website! h(t) = -9.8t^2 – 10t + 230, When it hits the ground, h(t) = 0, therefore -9.8t^2 – 10t + 230 = 0 Use the quadratic formula to find t In this problem: x=t; a=-9.8; b=-10; c=230 : I'll let you do the rather tedious math here, you should get a positive solution of about 4.36 seconds

Human-and-algebraic-language/593668: The youth group at the church decided to plant geraniums and daisies around the church grounds as a group project. Geraniums in 6” pots cost $4 each and daisy plants cost $6 each. The youth group spent $410 on 80 plants. How many geraniums and how many daisy plants did the group buy? 1 solutions Answer 376532 by ankor@dixie-net.com(15652)   on 2012-03-31 21:34:32 (Show Source): You can put this solution on YOUR website! Geraniums in 6” pots cost $4 each and daisy plants cost $6 each. The youth group spent $410 on 80 plants. How many geraniums and how many daisy plants did the group buy? : Let g = no. of Geraniums Let d = no. of Daisies : The no. of plants equation g + d = 80 g = (80-d); we can use this for substitution : The cost equation 4g + 6d = 410 replace g with (80-d) 4(80-d) + 6d = 410 320 - 4d + 6d = 410 -4d + 6d = 410 - 320 2d = 90 d = 90/2 d = 45 daisies then g = 80 - 45 g = 35 geraniums : : Check these solutions by finding the total cost 4(35) + 6(45) = 140 + 270 = 410

Numbers_Word_Problems/593804: Find four consecutive even integers such that if the sum of the first and third is multiplied by 4 the result is 10 more than 7 times the fourth. 1 solutions Answer 376527 by ankor@dixie-net.com(15652)   on 2012-03-31 20:08:00 (Show Source): You can put this solution on YOUR website! Find four consecutive even integers x, (x+2), (x+4), (x+6) : such that if the sum of the first and third is multiplied by 4 the result is 10 more than 7 times the fourth. 4[x + (x+4)] = 7(x+6) + 10 : 4(2x+4) = 7x + 42 + 10 : 8x + 16 = 7x + 52 : 8x - 7x = 52 - 16 : x = 36 is he 1st integer : 36, 38, 40, 42 the four consecutive integers : : Check this in the statement: "sum of the first and third is multiplied by 4 the result is 10 more than 7 times the fourth" 4(36 + 40) = 7(42) + 10 304 = 294 + 10
