Answer: $4.95
20 • .30 = 6
20 - 6 = 14
14 • .075 = 1.05
14 + 1.05 = 15.05
20 - 15.05 = 4.95
Answer:
cos(pi/2) + i sin (pi/2)
Step-by-step explanation:
(1+i)/ (1-i)
Multiply top and bottom by (1+i)
(1+i) (1+i)/ (1-i)(1+i)
Foil the top (1+i)(1+i) = 1 +2i +i^2 = 1 +2i -1 = 2i
Foil the bottom ( 1+i)(1-i) = 1 - i^2 = 1 - (-1) =2
2i/2 = i
the magnitude is (0^2+1^2) = 1
The angle is tan^-1( 1/0) = pi/2
cos(pi/2) + i sin (pi/2)
Answer:
20/27 or 0.74
Step-by-step explanation:
The total number of people is: 2+6+5+14 = 27
Total number of people that don't have a cat is: 6+14 = 20
20/27 = 0.74
Answer:
The answer to your question is 64 mm³
Step-by-step explanation:
To calculate the volume of a cube just multiply the length of a side three times.
Data
cube-shaped crystal
length = 4 mm
Formula
Volume = length³
Substitution
Volume = (4 mm)( 4 mm)(4 mm)
Simplification and result
Volume = 64 mm³
(16+10)-1+13*5
26-1+65
25+65
90
