Answer:
The jar has 32 dimes and 18 quarters
Step-by-step explanation:
<u>To solve this problem we can create a system of linear equations in terms of two-variables (say </u>
<u> and </u>
<u>) and solve it.</u> To begin let us analyze the problem further. We know that the values of each coin type are:
Dimes ( ) = $0.10
Quarters( ) = $0.25
Total Value = $7.70
Total Coins = 50
Now let us set up our system of equations as:
Eqn.(1)
Eqn.(2)
Lets take Eqn.(2) and rerrange it to solve for as:
Eqn.(3)
Now lets plug this, in Eqn.(1) so we get the value of as:
Plugging in 
back in Eqn.(3) we finally have:
Thus we conclude that in the jar the coins are:
Dimes ( ) 
Quarters( )

Answer:
120 degrees.
Step-by-step explanation:
If it is a regular 6 sided figure then each interior angle is 180 - (360/6)
= 120 DEGREES.
20+20=40*.1 (10%) =4
40-4=36
<span>Answer:
P=27
Q=10
TC=280
TC=FC+VC
FC=30
VC=280-30=250
TR=Q*P=10*27=270
Profit=TR-TC=270 - 280= -10
In short-tun Bob should continue mow lawns because he covers fixed costs (overvice instead of loss -10 he would had loss amounting fixed costs - 250)
In long-run he should close production.</span>
