1 week = 7 days....so 1 week and 1/2 day = 7.5 days
2760 / 7.5 = 368 miles per day <==
question 1 is congruent. 2 is not congruent and 3 is congruent
Five out of ten or 1/2 depends if it is a 6-numbered die.
A nine can go into a 20 two whole times. After that, there's still
some room left in the 20, but it's only enough room for a 2.
13)
Circumference (C) = 2π·r
11π = 2π·r
11/2 = r
******************************
Area (A) = π·r²
= π·(11/2)²
= 121π/4
≈ 94.985 in²
14)
diameter = 2r
42 = 2r
21 = r
*******************
Area (A) = π·r²
= π·(21)²
= 441π
≈ 1384.74 in²
***************************
$280/1384.74 in²
x = $0.20
Answer: about 20 cents per square inch
