Step-by-step explanation: Its D.
Circumference equals 2 * pi * radius. Your radius is 37 feet. So 2*2.14*37
and that equals 232.36
Answer:
a) t = -7
b) f = 12
c) k = -13
Step-by-step explanation:
a) t + 11 = 4
t = -7
b) f = 8+4
f = 12
c) 5 = 18 + k
-13 = k
Answer:
14.04 miles per hour
Step-by-step explanation:
The problem is asking for Izumi's speed. The formula of speed is:
- s = , where "s" means speed, "d" means distance and "t" means time.
The problem is also asking for the unit<u> miles per hou</u>r () so, this means that we have to know how many miles Izumi ran, given that the problem only mentioned<u> yards (110 yards).</u>
Let's convert 110 yards to miles, provided that he Izumi ran 1,760 yards in a mile.
- 110 yards ÷ 1760 = 0.0625 miles (this is the distance covered by Izumi in miles)
Let's go back again to the formula: s =
s = = 0.0039
Since, the we arrived at a miles per second unit, we have to convert it to miles per hour.
So, if a minute has 60 seconds, then an hour has 3,600 seconds.
Thus, 0.0039 × 3,600 = 14.04 miles per hour (the answer)
(13+14)+11= 13+(14+11)
