Answer:
80 minutes
Step-by-step explanation:
1. Determine the volume of the tank
volume = length x width x height
100 cm = 1 meter
80cm /100 = 0.8m
1.2 x 1 x 0.8 = 0.96m³
2. convert litre to meter
1 liter = 0.001 m
2 litres = 0.002m
3. determine the time it would take to fill 0.96m
(0.96x 10) / 0.002 = 4800 seconds
4. convert seconds to minutes
60 seconds = 1 minute
4800 seconds / 60 = 80 minutes
2l = 0.0
Answer:
x would be equal to 70 grades
Step-by-step explanation:
The angle QRS is equal to 180 - 130 = 50 grades.
We add up that with the other 60 grades on the left, and we encounter ourselves with a simple equation:
60 + x + 50 = 180
x = 70

Answer: the employee worked for 41 hours
Step-by-step explanation:
Let x represent the total number of hours that the employee worked. An employee earns $7.00 an hour for the first 35 hours worked in a week and $10.50 for any hour over 35. Let y represent the amount earned for x hours. Therefore
y = 7×35 + 10.5(x - 35)
y = 245 + 10.5x - 367.5
One week's paycheck (before deduction) was for $308.00. This means that y = $308.00. Therefore,
308 =245 + 10.5x - 367.5
308 = 10.5x - 122.5
10.5x = 308 + 122.5 = 430.5
x = 430.5/10.5
x = 41
I believe it is f(x)=5|x|
I suggest you get a second opinion, though
