Answer:
The answers should be A, E, and F.
Step-by-step explanation:
The rule for multiplying the same bases, but with different exponents, goes like this. Lets say you have four to the 5th power, and four to the 7th power. When you multiply them, the base will stay as four, but you will ADD the exponents! So, the answer to this would be four to the 12th power. This rule can even be applied when one, or even <em>both</em> of the exponents are negative! However, keep in mind that this can only be done when the base integers are the SAME.
We need to find the volume of a rectangular prism with dimensions 6 ft, 10 ft, and 12 ft:
• The volume of a rectangular prism is given by the product of its dimensions.
Thus, the volume V of the room is given by:
Therefore, that volume is 720 cubic feet.
Answer:
slope of line ax + by = c is -a/b
so, slope of 7x +2y =5 is -7/2
The population density is 73.54 people per square kilometer
<em><u>Solution:</u></em>
Given that,
Area of europe = square kilometers
Population =
<em><u>To find: population density</u></em>
<em><u>The formula for population density is given as:</u></em>
<em><u>Substituting the values in formula, we get</u></em>
On rounding to nearest hundreth (two decimal places ), we get 73.54
Thus the population density is 73.54 people per square kilometer
