I just know you can eliminate a which 18 degrees and c which is 61 degrees because m
-x>-7 is the answer the line
_
Answer:
Part A: Triangles GCB and PBE
Part B: They're similar because they have the same internal angles.
Part C:
250/400 = BE/450
112500/400 = BE
BE = 281.25 ft
250/400 = PE/350
87500/400 = PE
PE = 218.75 ft
Step-by-step explanation:
A/B=5/7 , B/C=6/12
Taking B=12×7=84, we get
A=12×5=60, C=7×6=42
Hence,
60:84:42. Answer
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
