    I have got myself in a pickle. :( [Word problem Test]

    I have a Word Problem Test due tom. at 8 am.( only 10 problems ) First of all this is my first semester at a university and I am pretty much overwhelmed! Second I also have an online History Test due at 12 am tonight! Plus an English test due tom. at 10. I have tons on my plate!!!! Can anyone Help, Please? If I make a 100 on this test $40 will be in your mailbox!!!!! I know thats not alot but I am a poor College girl, its the best i can do. If you love doin word problems and you will help me, what do you have to lose... So i guess I'm pretty much Beggin at this point... mm?

    Ok here it is: 10 questions



    1. An inlet pipe can fill a large water tank in 240
    minutes. An outlet pipe can empty the same
    water tank in 5 hours. Given an
    empty water tank, activate both pipes.
    Question: How many minutes will it be before
    the tank is completely filled?
    Round to the nearest minute.
















    2. Tub A contains 12% apple cider.
    Tub B contains 55% apple cider.
    How many ounces of cider from each tub
    must be gotten to make a 64 ounce drink that
    is 20% apple cider?











    3. Mary is running to school. She leaves home at
    7:00 AM trotting at a speed of 12 mph.
    Her little lamb leaves home at 7:15 AM
    running after her at a speed of 17 mph.
    What time of day will the lamb catch Mary?
    Round your answer to the nearest minute.
    (Example: 10:27 AM)









    4. Granny needs 3 gallons of 15% vinegar for
    her pickles. Bud went to the store and bought
    2 gallons of 50% vinegar. Granny asks:
    How much pure spring water must I mix with
    some of that 50% stuff to get my canner
    filled with 3 gallons of 15% solution?









    5. Use the formulae:

    Given: distance =16t^2 for a falling object,
    And the fact that distance=1100 *t, where the speed of sound is 1100ft/sec in air.
    If you drop a rock into a deep dark well and note that it takes 7 seconds to hear a splash after you drop the rock, how deep is the well? Hint: it takes some time for the rock to fall and then the remainder of the time for sound to travel back up the well for you to hear the splash. You will need the Quadratic formula to solve this one.













    6. Find three consecutive odd whole numbers, such that
    if three times the second is subtracted from the third
    that this will equal the first minus one hundred thirteen.











    7. Calculate the Medical Dosage.
    Given that a saline medicine bottle contains 5 milligrams
    of Tylenol for each 9 ml of saline
    solution in which it is dissolved.
    Grandma Wilson, who weighs 188 pounds needs
    25 milligrams of Tylenol per 50 kilograms of body
    weight for an I.V. How many ml of saline must she be administered?
    Note: 1kilogram=2.2pounds















    8. I have a collection of nickels, dimes, and quarters
    in a money bag worth $7.95. If the number of
    quarters is one more than the number of nickels
    and the number of dimes is five more than the number
    of nickels, find the number of each type of coin.
    # Nickels ________
    # Dimes_________
    # Quarters________













    9. Freezing weather is coming!
    The radiator in my 450 John Deere track loader
    is full with 18 quarts of fluid that is 15% antifreeze.
    Question: How much must I drain out into a disposable container,
    Then retighten drain plug, and pour back 100% pure
    antifreeze into radiator to make 18 quarts of 40%
    antifreeze.
















    10. Solve the following equation for x.


    3x-1 + x+2 = 5
    5 9

    Substitute your value of x back into the equation
    to show that the left hand side equals the right
    hand side.

    Well I already solved the first one for you...

    10.  3x - 1 + x + 2 = 5

     4x + 1 = 5

     4x = 4

     x = 1.

    6. Let x be the first number.

    So the second number is x + 2 and the third is x + 4.

    By translating the words into maths we find

    x + 4 - 3(x+2) = x - 113

     x + 4 - 3x - 6 = x - 113

     -2x - 2 = x - 113

     113 - 2 = x + 2x

     111 = 3x

     x = 37.

    So the three numbers are 37, 39 and 41.

    thank you so much

    You are really awesome! on the #10 though, it is:
    (3x-1)/5 + (x+2)/9 =5 solving for x but thank you ne way.. lol

    Ah ok...

    In that case...

    \frac{9(3x - 1) + 5(x+2)}{5 \times 9} = 5

    \frac{27x - 9 + 5x + 10}{45} = 5

    32x + 1 = 245

    32x = 244

    x = \frac{244}{32} = \frac{61}{8}
