Answer:
9
Step-by-step explanation:
The number of darts that failed to hit the bulls eye is 40% of 15 subtracted from 15
Since 40% of the darts hit the bulls eye .
Therefore
40% of 15
40/100 x 15
0.4 x 15
6
This means that 6 darts hit the bulls eye.
Therefore,number of darts that did not hit the bulls eye is
15 - 6 = 9
9 darts failed to hit the bulls eye
Is that your test or homework
53.70 - 9.60 = 44.10. 44.10 / 2 = 22.05. Each friend paid (not including the tip) $22.05.
Let
x---------> the length side of rectangle
y---------> the width side of rectangle
we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2
28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m
the answer is
the length side of rectangle is 240 m
the width side of rectangle is 120 m
