Area of a quarter circle = 1/4 * pi * r^2
= 1/4 * pi * 4^2 = 12.6 m to 3 sig figs.
perimeter = 4 + 4 + 1/4 * 2 pi * 4 = 14.3 to 3 sig figs.
It’s the second one , im pretty sure .
To find the mean absolute deviation, u have to find the mean of the data set first. after u find the mean, u subtract to find the numbers distance from the mean. after u do that, u then add up all the new numbers and then divide by how many numbers there are in the data set, and whatever ur answer ends up being is the mean absolute deviation of ur data set.
Your neighbor will let you take water from the well on his claim,
charging you $.05 a quart.
If 'x' is the number of quarts you take from his well on Tuesday, then
'y' is the amount of money you owe him before the sun goes down.
D. (5/9v - 5/9)
<u>Step-by-step explanation:</u>
(2/9v)- (-1/3v+ 5/9)
Since it is subtraction, we have to change the sign of the second expression that is after the (-) sign.
= (2/9v + 1/3v - 5/9)
Since we have different denominators, we have to take LCM of 3 and 9 as 3, so the expression becomes,
= (2/9v + 3/9v - 5/9)
= (5/9v - 5/9)
