The power in C is correct. it is x / 37 So B,C and D all have the correct power. Now you must turn to the base. You are talking about a half life so what is raised to the the correct power must be 1/2

That eliminates D and C both. 

A is gone because it has the wrong power. 

B <<<< the first part of the question's answer.

Now we will answer the 6 days part.

y = 477 * (1/2) ^(x / 37)
x = 6
y = 477 * (1/2)^ (6/37)
y = 477 * (1/2)^ (0.162 [repeating] )
y = 477 * 0.8397
y = 426.2876 which is confirmed by the answer  given. <<<< second answer.

Paha777 [63]

Answer:

Ok, she walks 3 miles to and from the library.

So in total, she walks 3 miles two times, then in one week, she walks 2*3mi = 6miles.

She says that she walked about 300 miles in total.

We must see if 300 miles is a multiple of 6 miles.

300mi/6mi = 50.

This means that she would walk about 300 miles since she started counting if she went to the library and back home exactly 50 times (again, since she started counting).

And she does this once a week, then if she started counting 50 weeks ago, then it is possible,

The highest point in the mountains of Seattle is 5,833 meters above sea level. The lowest point in the valley is 57 meters below
lana [24]

Answer: 5890 meters

Step-by-step explanation:

Given: The highest point in the mountains of Seattle is 5,833 meters above sea level.

The lowest point in the valley is 57 meters below sea level.

in integers it is represented by -57 meters. [we use negative integer to represents "below"]

Difference between the highest and lowest point = Highest point - lowest point

=  5,833 meters -(-57) meters

= (5833 + 57) meters      [a-(-b)= a+b]

= 5890 meters

Hence, the required difference = 5890 meters
