Question

A 5.9 liter container holds gal, expressed in scientific notation. 21 acres = km^2, expressed in scientific notation. 57.8 yards = mm, expressed in scientific notation. A snail moves 0.3 meters per day. How many centimeters per second does the snail move (expressed in scientific notation)? Answer: cm/sec. How many milligrams of a pesticide are in 315 ml of a 28.2 microgram/ml water sample? Answer: A partially used roll of fabric, 42 inches wide, has 77 feet of material remaining. It contains m^2. 21.6 sq yards + 94 m^2 cm^2, expressed in scientific notation. 0.5 fluid ounces of ethanol in 40 gallons of fruit punch = ml ethanol/ml punch

Explanation / Answer

13) one liter is equal to 0.264172 gallon and hence a 5 ltr can container can contain 1.32086 Gal (Gallon).

14) one acre is equals to 0.00404686 square kilometer and hence 21 acre means 0.084984 Km2(Square kilometer).

15) one yard is equals to 914.4 mm and hence 57.8 yards means 52852.32mm.

16) A snail moves at 0.3 meter/day

Hence it will move at (0.3*100*10)/(24*3600)cm/Second

Answer= 0.00347cm/Second

17)1 microgram=0.001 miligram

now 28.2 microgram/ml is equal to 0.0282miligram/ml

18) The width of the roll is=42 inch=1.0668 meter

The length of fabric is =77feet=23.4696 meter

The area of the fabric is = width X Length

=1.0668m X 23.4696m

=25.03m2

19) one sq yard is equal to 0.836127 sqmeter so,

21.6 sqyard+94 m2 =18.06035+94m2=112.16m2

20) One ounce is =29.5735 mililitre

one gallon is =3785.41mililitre

Now 0.5 ounce is added in 40 gallon hence the concentration is

14.7868/151416=0.0000976

Hence 0.5 ounces of ethanol in 40gallon of fruit punch=0.0000976mlethanol/ml punch
