Answer:
We know that the figure has a symmetry
angle 1 = angle 2
angle 1 =180°-(18°+90°) = 180° - 108°=72°
Therefore, <em><u>angle 2 =72°</u></em><em><u>.</u></em>
A square matrix that is not invertible is called singular or degenerate.
Answer:

Step-by-step explanation:
There are 1,000 milliliters in a liter. This means that in order to convert 600 liters to milliliters, you must multiply 600 by 1,000.
600 x 10^3 mL simplifies to 600 x 1,000 mL
The last expression is also 600 x 1,000 mL
The incorrect expression is the first one, since it is only multiplying by 100 mL instead of 1,000.
B) 32
Explanation:
let H = number of expensive high price stereo
systems
let L = number of less expensive low price
stereo systems
H +L = 50 =
3,000H + 80OL = 110,000
H = 50 - L (now replace)
3,000 (50 - L) + 800 L = 110,00
150,000 - 3,000L + 800L = 110,000
150,000 - 110,000 = 3,000L - 800L =
40,000 = 2,2OOL
L = 40,000 / 2,200 = 18.18 = 18 lower priced = =
stereo systems H = 50 - 18 = 32 higher priced stereo systems
=
=
(3,000 x 32) + (800 x 18) = 96,000 + 14,400 = 110,400
Even though the answer is not exact, if you had 33 high cost stereo systems, your inventory's cost = $112,600 which is $1,600 off
