Shima will mix 1 fluid ounce of fertilizer in water for every 40 square feet of soil. At this rate, which of the following expressions gives the number of gallons of fertilizer that Shima will mix in water for 0.5 acres of soil?
(Note : 1 acre = 43,560 square feet, 1 gallon = 128 fluid ounces)

Jenny has a pitcher that contains 1 gallon of water. How many times could Jenny completely fill the glass with approximately 16 fluid ounces? (1 gallon = 128 fluid ounces)

Which of the following statements is correct? 1.. Soil containg sand and Crop rotation protects soil fertility. 2. Clay soil can't hold water for a long time. 3.Upper layers of soil are made of rocks.

A square field measures 10 meters by 10 meters. Ten students each mark off a randomly selected region of the field, each region is square and has side lengths of 1 meter, and no two regions overlap. The students count the earthworms contained in the soil to a depth of 5 centimeters beneath the ground’s surface in each region. The results are shown in the table below. Which of the following is a reasonable approximation of the number of earthworms to a depth of 5 centimeters beneath the ground’s surface in the entire field?

Dogs need 8.5 to 17 ounces of water each day for every 10 pounds of their weight. Everett has two dogs-Ringo is a 35-pound black lab mix,and Elvis is a 55-pound beagle. Which of the following ranges represents the approximate total number of ounces of water,w, that Elvis and Ringo need in a week?

Express the following ratios in the language of daily life: In an examination, the ratio of the number of students passing the examination to the total number of students that appeared in the examination is 4:5. Water is formed by combining volumes of oxygen and hydrogen in the ratio 1:2. To dilute an acid, students were asked to mix acid and water in the ratio 2:3.

A solution M is prepared by mixing ethanol and water. The mole fraction of ethanol in the mixture is 0.9 Given: Freezing point depression constant of water (K_(f)^(water)=1.86 K kg mol^(-1)) Freezing point depression constant to ethanol (K_(f)^(ethanol))=2.0 K kg mol^(-1)) Boiling point elevation constant of water (K_(b)^(water))=0.52 K kg mol^(-1)) Boiling point elevation constant of ethanol (K_(b)^(ethanol))=1.2 K kg mol^(-1)) Standard freezing point of water = 273 K Standard freezing point of ethanol = 155.7 K Standard boiling point of water = 373 K Standard boiling point of ethanol = 351.5 K Vapour pressure of pure water = 32.8 mm Hg Vapour pressure of pure ethanol = 40 mm Hg Molecular weight of water = 18 g mol^(-1) Molecular weight of ethanol = 46 g mol^(-1) In anwering the following questions consider the solutions to be ideal dilute solutions and solutes to be non-volatile and non-dissociative. Water is added to the solution M such that the mole fraction of water in the solution becomes 0.9 . The boiling point of this solution is
