30 is your mystery answer :)
Answer:1/2b^2
Step-by-step explanation: The square is b^2?
Answer:
If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.
Step-by-step explanation:
Point B is located at (4, -2)
Answer:
x/3.5h = -$1.4
So, x = -$1.4 * 3.5h
= -$4.9
Step-by-step explanation:
Since your losing $1.4 every hour, the 1.4 is supposed to negative.
Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours
and get -$4.9.
