To do this, we first want to see how many participants there are in total by adding both males and females.

Now we know that there were 220 total participants, but only 121 were females.
This allows us to set up the fraction 121/220= the percent female.

or 55%
Answer:
s=21
Step-by-step explanation:
given ,
area=441cm^2
length (l)=s
we know,
or,l^2=441cm^2
or,l=√441cm^2
or,l=21cm
Answer:
17
Step-by-step explanation:
I believe the answer is 17.
Simplify
17
=17
Now,
Consider point O at zero on the number line.
Mark a point A such at number 4 such that OA= 4
Draw a perpendicular AB at point A of unit length.
Join AB
Taking radius of length AB draw an arc to intersect the number line at C.
Finally, OC=\sqrt{17}
Thus proving the answer is 17 or 
Answer:
C (Y = -5/8x - 10)
Step-by-step explanation:
first find the slope (y₂ - y₁) ÷ (x₂ - x₁)
(5 - (-20)) ÷ (-24 - 16)
-5/8 = slope (m)
now that we know the slope is -5/8 we can rule out A and B
now to find the y intercept just substitute a point in for x and y
5 = (-5/8)(-24) + b
multiply
5 = 15 + b
subtract 15 from both sides tp isolate b
-10 = b
