81÷s = 90÷100
s= 81 x 100 ÷ 90
s= 90
81 students is 90% of 90 students
The complete question in the attached figure
we have that
250°----------> belong to the third quadrant
if 2pi radians-------------> 360°
X-------------------------> 250°
X=250*2pi/360------------> 1.39 pi radians
then
<span>the radian measure of the central angle is 1.39pi
</span>
hence
the answer is
the option C) pi to 1.39pi radians
Answer:
12
Step-by-step explanation:
(10/y + 13) -3
Let y=5
(10/5 + 13) -3
PEMDAS says parentheses first
(2 +13) -3
15 -3
12
Let the smaller of the two numbers be x. Therefore the larger number is 1 bigger, x+1.

We can solve this equation for x, which will be one of our two numbers.



Now that we've found x, we can find x + 1. In this case,

.
Therefore, the two numbers are 29 and 30.
