Step-by-step explanation:
Answer:
10 pounds of the $1.50 chocolate were used.
30 - x represents the number of pounds of the 0.90 chocolate used.
Step-by-step explanation:
30 * 1.10 = 1.5x + 0.9 (30 - x)
33 = 1.5x + 27 - 0.9x
0.6x = 6
x = 10
To answer this case, you need to convert the blueprint measurement into the actual measurement by multiplying it with the scale. In this case, the scale is 8ft/1 inch. Then the calculation would be:
Rectangle actual length = rectangle blue print length * blue print scale
Rectangle actual length = 25 inch * 8ft/inch= 200ft
Rectangle actual width = rectangle blue print width* blue print scale
Rectangle actual width = 16 inch * 8ft/inch= 128ft
Rectangle actual area= Rectangle actual length * Rectangle actual width = 200ft * 128 ft= 25600ft square
Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2
approximately
