The total cost when Q = 10 is $150
Step-by-step explanation:
Th equation y = mx + b represents any linear function, where
- m is the unit rate
- b is the fixed amount
∵ The fixed costs are $100
∵ The variable costs are $5 per unit
∵ There are Q units
- Represent the total cost by the function c(Q)
∴ c(Q) = 5 Q + 100, where c(Q) is the total cost of Q units
∵ c(Q) = 5 Q + 100
∵ Q = 10
- Substitute Q by 10
∴ c(10) = 5(10) + 100
∴ c(10) = 50 + 100
∴ c(10) = 150
The total cost when Q = 10 is $150

1/50 of a mile is the distance the snail goes in 50 minutes. To get an hour, the snail must move for another 10 minutes (60-50=10).
Dividing 1/50 mile by 5 gives us 0.2/50 mile, which would be what the snail travels in 10 mins.
This can be added to 1/50 to give 1.2/50 mile as the answer
OR
You can take 0.2 and times it by 6 (to get 60 minutes from 10 minutes) to give the same answer as above.
Either way, the snail has gone 1.2 miles after the hour has passed.
Given:
Number of red marbles = 5
Number of blue marbles = 4
Number of yellow marbles = 3
To find:
The probability of pulling a red marble, then pulling a blue marble, without replacement.
Solution:
Probability formula:
We have,
Number of red marbles = 5
Total number of marbles is:
Probability of getting a red marble is:
After selecting one red marble, the remaining number of marbles is 11 and the number of blue marbles is 3. So,
Now, the probability of pulling a red marble, then pulling a blue marble, without replacement is:
Therefore, the correct option is B.
