There are two costs involved:
1) the cost for lunch, which is given as a rate per student: $7.25/student
2) the cost for the trip which is $443.75 to be divided by the 25 students, so it is $443.75 / 25 = $17.75/student
Now, you can add up those two costs per student to have the total cost per student:
$7.25 + $17.75 = $25.00/student
Answer: $25.00
Answer:
Step-by-step explanation:
The rate of infection is jointly proportional to the number of infected troopers and the number of non-infected ones. It can be expressed as follows:
Rearranging and integrating
At the initial breakout (t=0) there was one trooper infected (I=1)
In two days (t=2) there were 5 troopers infected
Rearranging, we can model the number of infected troops (I) as
30/150 = 80/x
Reduce the fraction:
1/5 = 80/x
Cross multiply:
x = 5 x 80
x= 400
Answer: 400 zebras.
Answer:
No
Step-by-step explanation:
The set contains 2 different ranges for 1 domain. In this case, X = 1 returns 5 and -3, meaning it cannot be a function.
0.05 * 10 =0.5
If you want an equivalent expression as division simply divide both sides by either 0.05 or 10 and it'll be dividing:
10 = 0.5/0.05 OR 0.05 = 0.5/10
