Answer:
dimes = 32
quarters = 8
Step-by-step explanation:
set up a system of equations:
let d = # of dimes
let q = # of quarters
d + q = 40
.10d + .25q = 5.2
substitution method; let 'q' = 40 - d
.10d + .25(40 - d) = 5.2
.10d + 10 - .25d = 5.2
-.15d = -4.8
d = 32
q = 40 - 32 = 8

Answer:
Step-by-step explanation:
Three forces A, B and C pull on ropes tied to a ring such that ring is in equilibrium.
For the ring to be in equilibrium the force must be concurrent i.e. there line of action must be passed through a single point.
There is no net force when forces are concurrent.
When all three forces are equal then they should be at angle of
to each other.
A=B and B's supplement is 22 degrees, then B=158 degrees (180-22) and since A=B, B=158 and A=158
