Answer:
Total Bill = 4006 dollars
Step-by-step explanation:
A cell phone company charges a flat fee of 20 dollars plus 3 cents a call.
If there was a total of 200 calls for the month, the total charge by the cell phone company will be.
Let me convert all to cent first
100 cent = 1 dollar
20 dollar =20 *100
29 dollar = 2000 cent
Charge by the company for a call is 2003 cent
Let me put down the equation.
1 call = 2003 cent
200 calls =( 200 calls* 2003cent)/1 call
200 calls = 200 * 2003cent
200 calls = 400600 cent
Let's convert back to dollar
100 cent = 1 dollar
400600 cent = 400600/100
400600 cent = 4006 dollars
Answer:
6 liters
Step-by-step explanation:
Let x represent the amount of pure concentrate used to make the punch. Then the total amount of concentrate in the punch is ...
0.20·10 +1.00x = 0.50(10+x)
x +2 = 0.5x +5 . . . . . eliminate parentheses
0.5x = 3 . . . . . . . . . . .subtract 2+0.5x
x = 6 . . . . . . . . . . . . . multiply by 2
6 liters of pure concentrate must be added to make a 50% punch.
C = 2 pi r
C = 2 x 3.14 x 5
C = 31.4 yd
A = pi r^2
A = 3.14 x 5^2
A = 3.14 x 25
A = 78.5 yd^2
