Answer:
Step-by-step explanation:
m is number of miles
A: 45+0.21m (45 is the initial cost)
B: 28+0.38m (28 is the initial cost)
To know how in many miles the cost will be equal,
45+0.21m=28+0.38m
0.38m-0.21m=45-28
0.17m=17
m=17/0.17 = 100
So, at 100 miles the cost will be same for company A and B.
The delivery driver has to make deliveries at 5 locations <span>among the 6 locations. </span>This means the order of the probability is important because the route he will take from A to B is different with A to C.
So, you need to use permutation for this problem. The calculation would be:
6P5= 6!/ (6-5)!= 720 different routes

Answer:
-58
Step-by-step explanation:
6 (10 - 23) + 20
=6 x (10 - 23) + 20
= 6 x (- 13) + 20
= -78 + 20
= -58
Answer:
6:41
Step-by-step explanation:
We know that the number of students going on the field trip is 6.
To find the total number of students, add the number of students going on the trip and the number of students staying at the school: 6 + 35 = 41
So the ratio of the number of students going on the field trip to the total number of students is 6:41
