A dairy keeps two kinds of milk on hand, skim milk that has 0.2% fat and whole milk that has 3.4% butter fat. How many gallons of each type of milk does a company need to produce 340 gallons of 1% milk for a grocery store? A 17 foot long ladder is leaned against a wall so that the distance it reaches up the wall is 7 feet more than the distance between the base of the ladder and the wall. How far up the wall does the ladder reach and what is the distance between the base of the ladder and the wall?

Answer 1

N = of 3.4% Solution r let amount 3.4% milk the total û to be 340 gallen, therefore (340-2) = amount of 0.2% milk So the amount of butterfat equation 3.4 n +012 (340-2) = 1000de L (340) 100 100 100 3.40+ 68 -0.22 340 3.2a 279 = 272 3.2 2 85 gallen. So, 85 gallon of 3.4% milk required 340-85 = 255 gallon of 0.2% milk requered

length of ladder = 17 fost - distance b/w base of ladder & wall au fost 17 foot En 2² +72 0 By Pythagosus property Pas wall is perpendiculed to bases} blypoterise) É Base} + (Opendicular ) (17ja+ (1+70 289 =*+*+49 + 14m = 22²+144 -240 120 -712+1576-82. -120 0 = 2(x+15)-869 +15) 0 =61-8)(x+5) So, either x=8 fost of 27-19 feet But distance. can't be ove. fo, n=8 fast & h P= 2+ 72 15 foots So The wall fall up by is foot to reach. The distance blu base of ladder & wall = 8 fest.
