Answer: = 62.8 pounds of CO₂

Step-by-step explanation:

1 kilowatt per hour produces 0.99 pounds of C02.

The total wattage in hours used was;

= 7,043 * 9 hours

= ‭63,387‬ watts

In kilowatts;

= ‭63,387‬/1000

= 63.387 kilowatts

CO2 produced;

= 63.387 * 0.99

= ‭62.75313‬

= 62.8 pounds of CO2

A TV screen is 41 cm long and 31 cm high. The length of the diagonal is closest to: A) 49 cm Eliminate B) 51 cm C) 54 cm D) 48 c
GuDViN [60]

Answer:

The length of the diagonal is closest to 51 cm.

Step-by-step explanation:

Given:

TV screen is 41 cm long and 31 cm high.

Now, to find the length of the diagonal.

By using pythagorean theorem:

leg 1 = 41 cm, leg 2 = 31 cm.

Let the hypotenuse be x.

(leg 1)² + (leg 2)² = hypotenuse²

41^{2} +31^{2}=x^{2}

⇒1681+961=x^{2}

⇒2642=x^{2}

<em>Using square root on both sides we get:</em>

⇒51.40=x

<u><em>So, the length of the diagonal = 51.40 cm. </em></u>

<u><em>By rounding off of 51.40cm it becomes 51 cm.</em></u>

Therefore, the length of the diagonal is closest to 51 cm.
