Answer:
Step-by-step explanation:
C = 0.42b + 25
C = what ur gonna be charged
b = number of bricks
since b is the number of bricks, this equation is saying that each brick cost 42 cents. So that takes care of the bricks, but this equation also includes a delivery fee........the 25.....so they are charging a $ 25 delivery fee per load
The average rate of your heart beat is about 80 times per minute.
Therefore 80 x 1440(minutes per day) = is 115,200
Therefore you heart beats about 115,200 per day.
Answer:
Table C
Step-by-step explanation:
Given
Table A to D
Required
Which shows a proportional relationship
To do this, we make use of:
Where k is the constant of proportionality.
In table (A)
x = 2, y = 4
x = 4, y = 9
Both values of k are different. Hence, no proportional relationship
In table (B)
x = 3, y = 4
x = 9, y = 16
Both values of k are different. Hence, no proportional relationship
In table (C):
x = 4, y = 12
x = 5, y = 15
x = 6, y = 18
This shows a proportional relationship because all values of k are the same for this table
