Answer:
56.52 in
Step-by-step explanation:
Circumference Formula: C = 2πr
Since we are given radius <em>r</em> = 9, simply plug it into the formula:
C = 2π(9)
C = 18π
C = 56.5487
Answer:
adding salt makes the water freeze slower and evaporate slower too.
Step-by-step explanation:
While pure water freezes at 0°C (32°F), salt water needs to be colder before it freezes and so it usually takes longer to freeze. The more salt in the water, the lower the freezing point.
Answer:
x = 6
Step-by-step explanation:
AD is a midline segment and divides EB and EC in the same proportion, that is
= 
Substituting in values gives
= 
= 
( cross- multiply )
5x + 2 = 32 ( subtract 2 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
I'm assuming by overlined you meant repeating as when there is a repeating number in a decimal, it has a line over it to represent such.
In the quotient of 4 divided by 7, there are zero numbers overlined. This is because the answer is .5714285714, no numbers are consecutively repeating for a long or the rest of the number.
Hope this helps!
