Answer:
Step-by-step explanation:
The rate of change is a measure in which one variable is modified in relation to another. In this case we have the variables:
Temperature in
Time in
Now, to calculate the rate of change, we have to divide one variable by the other. In this case the change in temperature divided by the time variation
.
Hence, assuming the ambient temperature of the glass is and the elapsed time
we have:
Answer:
Grace jumps for 9 minutes.
Zoe jumps for 12 minutes.
Step-by-step explanation:
Let the time for which Grace jumps the rope = minutes
Let the time for which Zoe jumps the rope = minutes
As per question statement:
Number of times Grace jumps in one minute = 66
Number of times Zoe jumps in one minute = 56
Number of times Grace jumps in minutes = 66
Number of times Zoe jumps in minutes = 56
As per question statement:
Multiplying equation (1) with 66 and subtracting equation (2) from it:
By equation (1):
Therefore, the answer is:
Grace jumps for 9 minutes.
Zoe jumps for 12 minutes.
Answer:
Graph the line starting at the y intercept (-5), count up 1 and left 3 (because is negative). Once you have a few points draw the line to connect them.
