No, it is .2 less than 5.7
210/360 = 7/12, meaning the shaded area is 7/12 of the entire circle.
The circle has radius 12 in, so its total area is π (12 in)^2 = 144π in^2.
Then the area of the shaded region is 7/12 of this, or
7/12 * (144 π in^2) = 84π in^2 ≈ 263.89 in^2
Answer:
and 
Step-by-step explanation:
The number of people is
and the number of hours they are present in the space is
.
Per person entry cost is $8.
Per hour cost of rent is $40.
They plan to earn a minimum of $600.
Donations by all the people entering the space is 
Total cost of renting the space is
which will be subtracted from the total amount of donations.
The inequality that represents the situation is
and
.
The answer is TX. The sides of each triangle are correspondent, so RS is congruent to TX.
Answer:
700 -1 -200
75 1 5000
Step-by-step explanation:
1. the rule for the required matrix is:
![\left[\begin{array}{ccc}x_1;y_1;a\\x_2;y_2;b\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx_1%3By_1%3Ba%5C%5Cx_2%3By_2%3Bb%5Cend%7Barray%7D%5Cright%5D)
2. if to re-write the given equations, then:
700x-y= -200 and 75x+y=5000.
3. Finally, the answer is:
column№1 | column№2 | column№3
==============+===========+=============
row№1 700 | -1 | -200
row№2 75 | 1 | 5000
