Answer:
323.2 revolutions (324 revolutions (rounded) )
Step-by-step explanation:
Savannah has to cover 1100 feet
Sarah has to cover 1100 feet
Now,
For Savannah:
diameter is 26 in, so radius will be 26/2 = 13 inches
Circumference (1 rev) = ![2 \pi r = 2 \pi (13) = 81.68](https://tex.z-dn.net/?f=2%20%5Cpi%20r%20%3D%202%20%5Cpi%20%2813%29%20%3D%2081.68)
There are 12 inches in 1 feet, so distance to be covered in inches:
1100 * 12 = 13,200 inches
Number of revolutions = 13,200/81.68 = <u>161.6 revolutions</u>
For Sarah, it is the same so:
161.6 revolutions
Together:
161.6 + 161.6 = 323.2 revolutions to cover the whole distance (both)
Rounded, it is About 324 revolutions
So
2/6 of 318=106
so 106-1/2 or 106/2=53
So he has 53 boxes left
Answer:
1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies
2) Now let's consider any real number a no matter positive or negative we will have that:
![a-a =0](https://tex.z-dn.net/?f=a-a%20%3D0)
Or in the other case:
![-a -(-a) =-a +a=0](https://tex.z-dn.net/?f=-a%20-%28-a%29%20%3D-a%20%2Ba%3D0)
So then we can conclude that the expression is a general rule and is true
Step-by-step explanation:
For this case we can verify if the following expression is true or false:
The sum of x and it’s opposite is always zero?
If we want to proof this we need to show that for any number is true.
1) Let's consider the first case with the number 0 the oppose is also 0 and we have that 0-0=0 so then applies
2) Now let's consider any real number a no matter positive or negative we will have that:

So then we can conclude that the expression is a general rule and is true
The tax would be A.
