Answers:
L = 4
M = -3
--------------------------------------
Explanation:
On the left side, the number 20-12i is in the form a+bi where a = 20 and b = -12
On the right side, 5L+(4M)i is in the form a+bi where a = 5L and b = 4M
Equating the real parts a = 20 and a = 5L has us get
5L = 20
5L/5 = 20/5
L = 4
Do the same with the imaginary parts as well
b = -12
b = 4M
4M = -12
4M/4 = -12/4
M = -3
Answer:
-29.41%
Step-by-step explanation:
Original number of Pokemon cards with Joe = 85
Updated number of Pokemon cards after sale = 60
Percentage change =
=
=
=-29.41%
Hence the percentage change in Pokemon cards for Joe is -29.41%
The negative sign is due to the fact that the number of cards has decreaased from the original.
Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)
M<2 = 90 - 64 = 26
answer
26
Answer:
a is greater by 25
Step-by-step explanation:
if a=100
then,100-50=50-25=25
so same way= a is greater by 25
