Can someone please help I tried to attempt it but it wasn’t working for me
kakasveta [241]

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."

Shawn has 186 feet of fencing and plans to make a pig pen that is 15 feet wide. How long will the pig pen be? Remember the formu
Nadusha1986 [10]

Answer:

The length of the pig pen for fencing the plans is 28 feet .

Step-by-step explanation:

Given as :

The measure of the fencing = 186 feet

The width of the pig pen = w = 15 feet

Let the length of the pig pen = l = x feet

Now, To find the measure of the fencing , we calculate the perimeter of the plans .

So, <u>From perimeter method</u>

I.e Perimeter = 2 × Length +  2 × Width

or, 186 feet = 2 × l +  2 × w

Or, 186 feet =  2 × l +  2 × 15

Or, 186 - 2 × 15 = 2 × l

or, 186 - 30 = 2 × l

Or, 2 × l = 156

∴  l = \frac{156}{2} = 78 feet

So, The length of pig pen = l = 28 feet

Hence The length of the pig pen for fencing the plans is 28 feet . Answer
