Two shapes.. a circle and a rectangle. The width of the rectangle serves as the diameter of the circle.

Length = 140 m ; Width = 68 m

Circumference of a circle = 2 π r
circumference of a cirlce =  2 * 3.14 * (68m/2) = 2 * 3.14 * 34 m = 213.52

length = 2 * 140 m = 280 m

perimeter of the oval = 213.52 m + 280 m = 493.52 m

What is 1/2 plus 5/16
kompoz [17]
Convert the 1/2 to a number that has a 16 in the denominator
because you can only add or subtract numbers that have the same denominator
so 1/2 = 8/16

the 8 + 5 = 13
so  8/16 + 5/16 = 13/16

therefore your answer is 13/16

Certain day in Bogotá, the temperature in the morning was 10 C or 50 F. At noon, the temperature was 15 C or 59 F according to t
nikitadnepr [17]
Quick answer: 68oF <<<< 

A quick way to figure this out is to double the C temperature and add 30, just so you get an estimate. 
F ~ 2*20 + 30 ~ 70oF

Now let's use the actual formula
F = 9/5 * C + 32
F = 9/5 * 20 + 32
F = 180/5 + 32
F = 36 + 32
F = 68o

68oC <<<<< answer.
