The speed of the snake is 8.95 miles per hour.
Step-by-step explanation:
Step 1:
The snake travels at a speed of 20 meters in 5 seconds.
We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.
The distance covered in 1 second 
So the snake is moving at a distance of 4 meters per second.
Step 2:
To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.
So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.
4 meters per second 
miles per hour.
Rounding this off, we get the speed of the snake as 8.95 miles per hour.
Answer:
B. -3 1/2y + 2
Step-by-step explanation:
Our expression is: 
.
Let's first distribute out that parentheses. Remember that distribution is simply taking the sum of the product of the outside term with each of the inside terms. Here, the outside term is 1/2 and the inside terms are 4 and -2y:
Now, we have:
We want to combine like terms, which means combining all the terms with y in them:
Remember that -7/2 can be written as the mixed number -3 1/2, so our final answer is:
-3 1/2y + 2
The answer is thus B.

+8 to each side:
9j=16+9j
-9j from each side:
0=16
Which is false.

Answer : 
Given expression is 
To make perfect square trinominal we use completing the square method
In completing the square method we add and subtract the half of square of coefficient of middle term
Here coefficient of middle term is -7
Half of -7 is 
Square of is 
=
So the expression becomes ![x^2 - 7x + [tex] \frac{49}{4}](https://tex.z-dn.net/?f=%20%20x%5E2%20-%207x%20%2B%20%20%5Btex%5D%20%5Cfrac%7B49%7D%7B4%7D%20%20)
that gives perfect square trinomial
Hence , the value of 'c' is
