Answer:
The answer is 18.2045
Step-by-step explanation:
In order to determine the rounded number, we have to know about the notation numbers. In any number, every digit has a unique notation depending on his place.
I have attached an image that shows some notation numbers. We can see that the hundred-thousandth place is the fifth digit after the decimal point.
Then we have to see the next digit. If the digit is greater or equal than 5, we have to increase in one unit the number in the place we want to round. If not, the number does not change.
In this case:
Fifth decimal number is 9
Sixth decimal number is 8, so we have to increase 9 by 1.
Finally the number is 18.2045

Answer:
120 pounds
Step-by-step explanation:
We can use systems of equations to solve this problem. Assuming j is Jim's weight and b is Bob's weight, the equations are:
j + b = 180
b - j = 1/2b
Let's get b - j = 1/2b into standard form (b, then j, then the equal sign, then the constant.)
Now we can solve using the process of elimination.
Now we know how much Bob weighs, for fun, let's find Jim's weight by substituting into the equation.
So Bob weighs 120 pounds and Jim weight 60 pounds.

Okay Bright, so the central angle is 36 degrees, so according to the formula you have on the top of the screen, we have to do 36/360, which is 1/10 or 0/1.
Then we multiply that by the radius squared. 12^2 = 144.
Finally, we multiply 144 by 0.1, which is 14.4. So our answer is H. 14.4
.
Notice that we don't multiply the radius squared by, since the answers are in terms of .
