Answer:
90 degrees
Step-by-step explanation:
Angle DMC is vertical angles with angle AMB. Vertical angles always have the same degree measure.
Since angle AMB = 90 degrees, we know that because DMC = AMB, then angle DMC is also 90 degrees.
Hope this helps!
Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
Answer:
Step-by-step explanation:
The answer is 2.2
–2x + 4y = –7 . . . . . (1)
y = -1/2x + 5 . . . . . . (2)
Putting (2) into (1), we have:
-2x + 4(-1/2x + 5) = -7
-2x - 2x + 5 = -7
-4x = -7 - 5 = -12
x = -12/-4 = 3
y = -1/2(3) + 5 = -3/2 + 5 = 7/2
Hence, the system has one solution.
