Answer:
The initial cash balance in bank is $46
Step-by-step explanation:
The equation given to determine b which is the initial money before she withdrew $60 is
b + (-60) = -14
Let's solve for the value of b which is the initial balance of the money in the bank.
b + (-60) = -14
b -60 = -14
b = -14+60
b = 60-14
b = 46
The initial money before she withdrew $60 was $46
Answer:
6.875° C
the mean of a set of data is calculated using
mean =
For the first 7 days the mean is 8 and the count = 7
8 = ( cross- multiply )
sum = 8 × 7 = 56
Add on the temperature on the 8 th day to the sum and divide by 8 for mean
sum = 56 - 1 = 55
mean = = 6.875° C
2nd question
Height of marble from the ground
An independent variable is the variable in an experiment that you change to see if it has an effect on the dependent variable. In this case, Jack wanted to see whether the position of the marble on the ramp (which would be the height) has an effect on the kinetic and potential energy of the marble, then the height would be the independent because it is what is being changed.
The dependent would be the kinetic and potential energy and the constant would be the type of marble.
The answer is 14.715 do the work on your own
Hey there!
63 = 13 + 2P subtract 13 from both sides
50 = 2P divide both sides by 2
25 = P
So the cost of one pass = $25
Hope this helps!
