Answer:
280000lb
Step-by-step explanation:
In this question, we shall be calculating the amount of carbon iv oxide prevented from entering the atmosphere.
Generally we know that 1kwh produces 1.37 lbs of Carbon iv oxide in the atmosphere
Now, using a 100 watt light bulb daily for 8 hours, for a year, the amount of Carbon iv oxide produced will be;
100 * 1.37 * 8 * 365 = 40040 lb
Using a 30 watt CFL for 8hrs/ day for a year, we have;
30 * 1.37 * 8 * 365 = 120012 lb
Now calculating the amount of CO2 prevented, we have 40040 - 120012 = 280028 lb = 280000 after rounding up
Step-by-step explanation:
D.the set of all possible output values.
The answer is A) 6 inches.
First I punch square root 13 in the calculator and got 3.6055... then I square the number since the formula has square root on it and got 13. Now the equation look something like this: 13 + b^2 = 49. 49 because 7^2 is 49. Then i subtract 49 by 13 and got 36. Now the equation look like this: b^2 = 36. After I square both side, I get b=6 in.
Answer:
The length of the inclined plane AC = x = 8.6 ft
Step-by-step explanation:
Height = AB = 5 ft
BC = 7 ft
Now length of inclined plane AC = x
Apply pythagores theorem for ΔABC
x = 8.6 ft
Therefore the length of the inclined plane AC = x = 8.6 ft
Let x be the number Henry is thinking of.
The number is doubled and got an answer of 4.
That means:
2 · x = 4
or
2x = 4
This is the equation when Henry doubled the number and got 4 as an answer.
Solve it by dividing both sides by 2.
2x ÷ 2 = 4 ÷ 2
x = 2
The original number Henry was thinking was 2.
Cheers!
