Used to flavor vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest amount. the threshold limit is 2.0 x 10-11 g per liter of air. if the current price of 50.0 g of vanillin is $104, determine the cost to supply enough vanillin so that the aroma could be detected in a large aircraft hangar with a volume of 5.95 x 107 ft. guided solution

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
