Answer:
Charlie has used his phone in a month for at least 1404 minutes
Step-by-step explanation:
In order to solve this problem, we must first determine what will our variable be and what it will represent.
Let's say our variable is x and it will represent the number of minutes Charlie has used his phone.
After we set our variable up, we can set our equation up. The problem states that Charlie will pay a monthly fee of $18 and additional $0.06 per minute of use. The $18 is what is called a fixed cost and the $0.06 is the variable cost, which will depend on our variable x (the number of minutes spent). Taking this into account we can build an inequality that will represent the amount of money spent in a month, which will look like this:
so now we can solve that inequality for x, we can start by subtracting 18 from both sides, so we get.
Next, we can divide both sides of the inequality by 0.06 so we get:
so that's where the answer came from. Charly has used an amount of at least 1404 minutes
Answer: ! which is PEA
Step-by-step explanation:
The entire length of the line, AE, is 38. We are asked to find the length from point C to point E.
AB and BC are both 5 units in length. The length from point B to point D is 17. So, if we subtract 5 from 17, we get 12.
The length between point C and point D is 12. DE appears to be of the same distance. So, DE is also 12.
12 + 12 = 24
So, CE = 24.
Step-by-step explanation:
Dividing the shape into two:
The area of the rectangle is
A= 13.5*4.8= 64.8km2
the area of the triangle
A = [( 5.7-4.8) *13.5 ]/ 2= 6.075km2
Therefore the total area is
At = 64.8 + 6.075 = 70.875km2
