Answer:
a. Andrea is incorrect
b. By solving for x, we find that x does not equal 8, but it is equal to 7.
Step-by-step explanation:
8+4=2(x-1)
8+4=2x-2
12=2x-2
14=2x
x=7
Answer:
3/8 pounds of meat
Step-by-step explanation:
7/8 pounds of ham
= 0.875 pounds of ham
1 3/8 pounds of turkey
= 11/8 pounds of turkey
= 1.375 pounds of turkey
Pounds of meat
P_meat = 0.875 pounds of ham + 1.375 pounds of turkey
P_meat = 2.25 pounds of meat
Jon puts 1/6 of the meat on each sandwich
P_meat/6 = 3/8 pounds = 0.375 pounds

t=1,5
Answer:
V = 1250π/3 mm³
V = 1309 mm³
Step-by-step explanation:
The composite figure is made up of a cylinder with radius 5 mm and two hemispheres of radius 5 mm. The height of the cylinder is
20 mm - 5 mm - 5 mm = 10 mm
The two hemispheres make up a full sphere of radius 5 mm.
V = πr²h + (4/3)πr³
V = π(5 mm)²(10 mm) + (4/3)π(5 mm)³
V = [(25 mm²)(10 mm) + (4/3)(125 mm)³]π
V = [250 mm³ + 500/3 mm³]π
V = 1250π/3 mm³
V = 1309 mm³
