Clark plans to fertilize his yard this summer. his yard is 40 feet wide a 60 feet long. thus included a 4 foot wide and 20 foot long flower bed, which he will not fertilize. a bag of fertilizer costs $8.25 and covers 1,000 square feet. he also hopes to fertilize his neighbors yard the neighbors yard is 50 feet wide and proportional to clarks yard including a 5 foot wide and 30 foot long flower bed that will not be fertilized how long is the neighbors yard? set up a proportion. how many square feet of his own yard will clark fertilize. if clark bought only 3 bags to fertilize both yards how many square feet will remain unfertillized when he runs out

Step-by-step explanation:

the area of Clark's yard = 60 * 40 = 2400 square feet

the area of the flower bed in his area = 4 * 20 = 80 square feet

the area to be fertilized = 2400 - 80 = 2320 square feet

∵the two yards are proportional

∴ where L1 and W1 are the length and width of clark's yard and L2 and W2 are his neighbor's yard

L2 = 75 feet

the area of his neighbors yard = 75 * 50 = 3750 square feet

the area of flower bed = 5 * 30 = 150 square feet

area to be fertilized = 3600 square feet

the area that will remain unfertilized = 5920 - 3000 = 2920 square feet

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

78.59 is the mean
