If a 4000 watt oven is on for 5 hours, then how many kilowatt-hours (kw-hrs) of energy are used?
Solution: We are given that the oven is 4000 watt and it is on for 5 hours.
We have to find the how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
We first need to convert watts into kilowatt's. We know that:
Therefore, 4000 Watts
Now, we can find how many kilowatt-hours (Kw-hrs) of energy are used by the oven.
Energy used by the oven Kw-hrs
Therefore, 20 kilowatt-hours (kw-hrs) of energy are used by the oven.

V=4/3πr³
the radius of the sphere will therefore be given by:
5000π=4/3πr³
solving for r we get:
r³=3750
hence
r=15.54 m
the area will therefore be:
A=4πr²
A=4π(15.54)²A=965.49π m²
Answer:
3,033.11 m²
Step-by-step explanation:
V=3/4πr³
5,000π= 4/3 πr³
5,000= 4/3 r³
3/4 x 5,000 = r³
3,750 = r³
r = 15.536
SA = 4πr²
SA = 4π(15.536)²
SA = 3,033.11 m²

The average amount of mercury in the population of large-mouth bass in this particular state
Step-by-step explanation:
Parameters are properties that describe entire populations rather than a sample. Therefore, since researchers are focused on the average mercury content of large-mouth bass, the correct parameter for the experiment would be the average amount of mercury in the population of large-mouth bass in this particular state.

Answer:
y = -7/5x - 6.7
Step-by-step
y = -7/5x + 6. A Line that is parallel will always have the same slope. The slope is m. m in this situation = -7/5x. A lines equation is y = mx + b. m = -7/5. y = -7/5x + b. Now to find b we can substitute the given point which goes through the new line, (2, -6). In this point x =2 and y = -6. Now substitute the x and y values into our equation. y = -7/5x + b is now -6 = -7/5(2) + b. -7/5(2) = -7/10. -6 = 7/10 + b. Subtract 7/10 from -6. Its -6 and 7/10 or -6.7 . -6.7 = b. b = -6.7. Now substitute the b value into the equation. y = -7/5x -6.7.
