A​ long-distance telephone company charges a rate of cents per minute or a ​-cent minimum charge per completed​ call, whichever
LiRa [457]

Answer: 50 cents

Step-by-step explanation:

Company charges 8 cents per call and the call in question is 3 minutes. Cost is;

= 3 * 8

= 24 cents

Company however stipulates that a call is 8 cents per minute or a 50​-cent minimum charge per completed​ call, whichever is greater.

<em>50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.</em>

For what value of a is the volume of the tetrahedron formed by the coordinate planes and the plane (x/a) (y/10) (z/6)
kotykmax [81]

This question is incomplete, the complete question is;

For what value of a is the volume of the tetrahedron formed by the coordinate planes and the plane (x/a) + (y/10) + (z/6) = 1 equal to 10?

Answer: the value of a is 1

Step-by-step explanation:

Given that;

Volume of tetrahedron bounded by plane (x/a) + (y/10) + (z/6) = 1

and coordinate plane is; V = 1/6|abc|

(x/a) + (y/10) + (z/6) = 1

volume = 10

so

10 = 1/6 | a × 10 × 6 |

60 = a × 10 × 6

60 = 60a

a = 60 / 60

a = 1

Therefore the value of a is 1

On a map, the length of a nature trail is 7.2 centimeters. If the scale is 1 centimeter to 25 kilometers, what is the actual len
Lisa [10]
A:b=c:d
7.2:x=1:25. If u see two ratios equal each other, the product of a and d is equal to the product of b and c. This means that (7.2 times 25) is equal to x. This equals 180=x. The actual distance of the trail of 180 km. Hope this helps!
