The answer is A, 8.94 seconds.
Since Gary ran 0.93 seconds faster than Brian, his time will have 0.93 seconds more than Brian's. To figure out Brian's time you have to subtract these 0.93 seconds from Gary's time.
9.87 - 0.93 = 8.94
I hope this helps!

Step-by-step explanation:
Answer:
25/64
Step-by-step explanation:
C=πd
find diameter:
small= 15 x 15= 225
large= 24 x 24= 576
multiply:
225 x 3.14= 706.5
576 x 3.14= 1808.64
ratio:
706.5/1808.64
reduce:
25/64
In the triangle...the length of the longer side is tan 60 multiply by the shorter leg. Tan 60 = sq root 3...thus
Longer side = sq root 3 times the length of the shorter leg
Answer:
D 60
Step-by-step explanation:
Fist we can determine y
7y+5y = 180 since it is a straight line
12y = 180
Divide each side by 12
12y/12 =180/12
y = 15
We also know that 5y+3y +x = 180 since the angles of a triangle add to 180
8y +x = 180
8*15 +x = 180
120+x = 180
Subtract 120 from each side
120-120+x = 180-120
x = 60
