Answer:
$31.70
Step-by-step explanation:
In order to find the total monthly charge for the customer, you can set up an equation using two different variables and putting in the charges and number of calls for each.
Let 'x' = the number of in-state calls and 'y' = the number of out-of-state calls.
Equation: 0.03x + 0.11y + 10.75 = total
Since the customer made 350 minutes of in-state calls, x = 350 and 95 minutes of out-of-state calls, y = 95:
0.03(350) + 0.11(95) + 10.75 = total
$10.50 + $10.45 + $10.75 = $31.70
It’s 75 have a nice day :))))
Answer:
no solution
Step-by-step explanation:
- Therefore, there is actually no solution! No solution of x, when added to 1, can make negative 4. This is because the absolute sign (the symbol that looks like bars: |#|) automatically makes a number positive.
The surface area of a cylinder with circular bases of radius <em>r</em> and height <em>h</em> is equal to the sum of the areas of the two circular faces and the area of the rectangular lateral surface:
<em>A</em> = 2π<em>r</em>² + 2π<em>rh</em>
If you know the height <em>h</em>, then you can solve the quadratic equation for <em>r</em>.
