Answer:
$3.50
Step-by-step explanation:
Let's split 2.5 into 2 separate parts, 2 and .5. To find how much 2 pounds of apples cost, we have to multiply $1.40 by 2. 1.40x2= 2.80. Now we have to figure out how much .5 pounds. To do this, we have to divide 1.40 by 2. We get .7. 2.80+ .7= $3.50 [or 3.5]
We are given with the rate of change of the base, db/dt equal to 1 ft/ sec and the rate of change of the height of the triangle, dh/dt equal to 2 ft/sec. b is 10 ft and h is 70 ft. Area of triangle is equal to A= 0.5 bh The rate of change of the area is equal to dA/dt = 0.5 b dh/dt + 0.5 h db/dt. Substituting, dA= 0.5*10*2 + 0.5*70 * 1 equal to 45 ft2 / sec.
