M = 6w - 31
m + w < 11
6w - 31 + w < 11
7w - 31 < 11
7w < 11 + 31
7w < 42
w < 42/7
w < 6
oldest age warren can be is 5...but I do not see how that is possibly because if warren is 5, then marty is : 6(5) - 31= 30 - 31 = -1
unless u make warrens age 5 1/2....making warrens age 2...wait, that wont work because u need a whole number
Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_
18 = r * 130 * pi / 180
18 = 2.269 r
r = 7.93 cm to neraest hundredth
The answer is: [C]: " -16√10 " .

" -4√160" = -4 * √160 " ;
________________________________________________________
√160 = √16 *√10 = 4√10 ;
-4 * * 4√10 = -16√10 ;
which is: Answer choice: [C]: " -16√10 " .

In 4.75 the 7 makes it round up to 5
Increased enrollment =9%
Last enrollment=3900
Current enrollment=9%of3900+3900
=9×3900/100+3900
=351+3900
=4451
