Answer: D) 8 hours
Step-by-step explanation:
Machine A: 840 an hour
Machine B: 760 an hour
h = hour
840 + 760 = 1600
In an hour, they can both sort 1600 mails.
1600h = 12800
Divide each side by 1600
h = 8
840 * 8 = 6720
760 * 8 = 6080
6720 + 6080 = 12,800
Answer:
A = 139.25 cm^2
Step-by-step explanation:
The composite shape is made up of a square with side 10 cm and a semicircle with diameter 10 cm. The area of the composite shape is the sum of the two areas. The diameter of the semicircle is the side of the square, and the radius of the circle is half of the diameter.
A = s^2 + (1/2)(pi)r^2
r = d/2 = s/2
A = (10 cm)^2 + (1/2)(3.14)(10 cm/2)^2
A = 100 cm^2 + (1/2)(3.14)(25 cm^2)
A = 139.25 cm^2
