Andre needs 12 cubic yards of mulch to put in his yard. HomeDepot has 2 cubic ft bags for $3.50. He called Max's Mulch and they will deliver 12 cubic yards of mulch for $450. Since there are 3 feet in a yard, which is the better option for Andre? Explain. a. Home Depot because it is $90 cheaper b. Max's Mulch because they are $117 cheaper c. Home Depot because it is $125 cheaper d. Max's Mulch because they are local and you should always buy local

b. Max's Mulch because they are $117 cheaper

Step-by-step explanation:

1 yd = 3 ft

(1 yd)^3 = (3 ft)^3

1 cu yd = 27 cu ft

12 cu yd * (27 cu ft)/(cu yd) = 324 cu ft

Andre needs 12 cu yd which is the same as 324 cu ft.

The Home Depot price is $3.50 for 2 cu ft.

($3.50)/(2 cu ft) = $1.75/cu ft

324 cu ft at $1.75/cu ft costs:

324 cu ft * $1.75/cu ft = $567

The Home Depot price is $567.

The Max's Mulch price is $450.

$567 - $450 = $117

Home Depot is $117 more expensive than Max's Mulch.

b. Max's Mulch because they are $117 cheaper

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,
