Answer:
c =4 4/9 minutes
Step-by-step explanation:
The formula is
1/a + 1/b = 1/c where a and b is the time for each working alone and c is the time working together
1/8 + 1/10 = 1/c
Multiply by 40c to clear the fractions ( 40c is the least common multiple)
40c(1/8 + 1/10 = 1/c)
5c + 4c = 40)
9c = 40
Divide by 9
9c/9 = 40/9
c =4 4/9 minutes
Answer:
The correct representation of data on x-axis and y-axis is:
x-axis: minutes in increments of 5; y-axis: temperature in increments of 5
Step-by-step explanation:
The minutes will be plotted along the x-axis with increment of 5 minutes because the minutes represents here the independent variable
and the temperature will be plotted along the y-axis with the increment of 5 degrees Celsius because the temperature denotes the dependent variable.
