Ratio of the radii = sqrt16 / sqrt81 = 4/9
so radius of circle Q is found by solving 4/9 = 8/x where x = radius of Q
x = 2*9 = 18
radius of circle Q = 18.
Answer:
b + b + 7 = 23
2b + 7 = 23
Step-by-step explanation:
b = girls
b + 7 = boys
Answer:
x + 5y = 0
Step-by-step explanation:
y = mx + b
y = -1/5 x + b
1 = -1/5 (-5) + b
1 = 1 + b
b = 0
y = -1/5 x
5y = -x
x + 5y = 0
Since 11 out of 55 specials were salmon filet,
The percentage of specials that were salmon filet is 11/55 = 20/100 = 20%.
