113,115,117 if you add them up you should get 345
Answer: 48.84
Step-by-step explanation:
First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)
Answer:
It will take the penguin 26.95 sec to walk 45 feet.
Step-by-step explanation:
Step-by-step explanation: Given. Distance = d = 10 feet. Time = t = 6 sec. First of all we have to calculate speed . Let s be the speed, then. Now, How far does the penguin walk in 45 seconds? Here we know the speed and the time . So, s=1.67 ft per sec. t = 45 sec
Answer:
and
respectively.
Step-by-step explanation:
The given trigonometric equation is
We divide both sides by 
to get,
This implies that,
We take the inverse tangent of both sides to get,
Since the tangent ratio has a period of 
, another solution is
to the nearest degree.
