Answer:
<h2>39 minutes</h2>
Step-by-step explanation:
In this problem we can see that there is a constant/flat rate charge of $4 on every first minute
we can model the cost for calls as

where x is the number of extra minutes spent
given that y = $13.75
We can simply substitute our given values into the equation 1 above and solve for x

Divide both sides by 0.25 to find x
Answer:
Circumference, C = 81.68 units
Step-by-step explanation:
Given that,
The radius of the circle, r = 13 units
We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :


C = 81.68 units
So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
Answer:
0.0723 cubic feet < 1 cubic foot.
Step-by-step explanation:
A cube-shaped salt lick is ordered by a rancher and the length of each salt lick is
foot.
Therefore, the side length of each salt lick of cube-shape is
foot.
So, the volume of each salt lick is
cubic feet.
Hence, this volume is less than 1 cubic foot. (Answer)
Answer:
14π cm
Step-by-step explanation:
Circumference of a circle given the diameter is :
πd
We simply substitute the value given in the image into our formula to find our answer:
πd = π×14 = 14π
Units will be cm as circumference is a length
This is our final answer as the question states to leave it in pi form .
