Step-by-step explanation:
......................
Area of wetlands lost per year = 60,000 acres per year
Number of years observed = 4 years
In 4 years:
Area of wetlands lost = 60,000 acres per year X 4 years
Total area of wetlands lost after 4 years = 240,000 acres
b. It depends on the value you assume for the power line voltage. If you assume it is 120 volts, then the ratio to battery voltage is
... (120 volts)/(1.2 volts) = 100
Power line voltage is 100 times as large as battery voltage.
_____
Please be aware of some difficulties in this question.
1. Power line voltage, even if it is "120 volts" varies over time from -170 V to +170 V, so is not really comparable to a battery's voltage, which is steady at 1.2 V.
2. The terminology "times larger" is ambiguous. When we answer the question, "how much larger is <em>a</em> than <em>b</em>," we give the response in terms of the difference a-b. Thus, if <em>a</em> is 2 times <em>larger</em> than <em>b</em>, we might be talking about the <em>difference</em> being twice the value of <em>b</em>. It is preferable to say "times as large as."
Options:
(12,0) (0,12) (3,-1) (0,-4/3)
Answer:
(12,0)
, (3,-1) and (0,-4/3)
Step-by-step explanation:
Given
Required
Which option is true?
A coordinate point is of the form; 
So, we have to substitute the x and y values in the given equation.
A. For (12,0)
and 
becomes
<em>This is true</em>
B. For (0,12)
and 
becomes
<em>This is false</em>
C. For (3,-1)
and 
becomes
<em></em>
<em></em>
<em>This is true</em>
D. For (0,-4/3)
and 
becomes
<em></em>
<em>This is true</em>
<em></em>
<em>Hence, (12,0)
, (3,-1) and (0,-4/3) are true values of the equation</em>
The answer would be7,500,000
