Whenever it’s to the power of 0 the answer is 1 but idk if it’s negative use photomath
Answer is 280
First, find A = 35% (100% less the three known percents = 35
Second, find ratio of B
20% of x = 160
Divide 160/.20 to isolate x
X=800 (total biscuits)
Now take A percentage x 800 biscuits
800 x 35% = 280 people chose biscuit A
A. Gloria because Gloria isn't being showed something shes the one showing something to someone else.
A^2+b^2= c^2
48^2+b^2= 80^2
2304+b^2= 6400
Subtract 2304 from both sides.
b^2= 4096
Find the square root.
b= 64
I hope this helps!
