Answer:
0.07
dollar per minute
Step-by-step explanation:
Given the charging formula :
C(n) = 13 +0.07n
n = number of minutes talked, and
C(n) = monthly charge, in dollars
The slope is the change in amount charged per change in the number of minutes talked.
Also, from The slope intercept equation :
y = mx + c
Comparing the equation :
0.07n = mx
m = 0.07
Since, The slope is the change in amount charged per change in the number of minutes talked.
Amount charged in dollars, talk time measured in minutes ;
Unit = dollar per minute

Answer:
5
Step-by-step explanation:
What we have to know is that when two triangles are similar their sides will always be proportional. So we will create a proportion that goes like this...
but since it doesn't tell us the exact value of triangle 1. We will have to add 3 and 12 to get 15 which is the base of the first triangle. Now we're ready to write the proportion.
Now we cross multiply and solve the equation...
So the value of x is 5.
she would need 166 boxes. there is a remainder of 1. one book wont fit in a box
