You are investing $2,000 fro 3 months and the APR is 4% so you will get one quarter of the APR for a year. For the year 4% interest is $2,00 x .04 or $80 for the year. # months is 1/4 of a year so divide $80 by 4 to get the interest fro 3 months which is 20 so the answer is B.
Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
Answer:
C'(-5, 2)
Step-by-step explanation:
Rule to be followed for a point rotated 180° about the origin,
(x, y) → (-x, -y)
From the figure attached,
When ABCD is rotated 180° about the origin, the new points of the image will be
A(2, 0) → A'(-2, 0)
B(4, 0) → B'(-4, 0)
C(5, -2) → C'(-5, 2)
D(1, -2) → D'(-1, 2)
Therefore, image of C will be C'(-5, 2).
Answer:
1 - 9/7n
Step-by-step explanation:
1/7 - 3 ( 3/7n - 2/7)
Multiple negative 3 in the numbers with parenthesis.
1/7 - 9/7n + 6/7
Combine terms.
1/7 + 6/7 = 7/7 which can be turned into a whole number so 1.
-9/7n cannot be added into anything.
1 - 9/7n
