B.2.06
C.2.5
D.3.2
E.12.8
Answer: D. 3.2
Step-by-step explanation:
Given : In parallelogram LMNO,
LM = 4.12, MN = 4, LN = 5, and OM = 6.4.
Diagonals and intersect at point R.
We know that diagonals of a parallelogram bisect each other.
Since R is the intersection point of both diagonals.
⇒R is the mid point of OM.
Thus OR=
Therefore, OR=3.2
Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)
