<span>reater than 3 tens 6 ones" probably means greater than 36, so maybe it's 37, 38, 39, and so on, up to 51. "It has more than 6 ones" probably means that it's got 7 or more in the ones place. so 40, 41, up to 46, and 50 and 51 can't be it. So we're left with 37, 38, 39, 47, 48, or 49 as possibilities for what Ava picked.</span>
Answer:
Step-by-step explanation:
We need to first find the perimeter of this oddly-shaped rink. We have a rectangle for which we are enclosing 3 of its sides, and the fourth "side" is a half-circle. Let's find the perimeter (or circumference) of the circle, divide it in half because we have half a circle, then add in the remaining 3 sides from the rectangle, shall we?
C = πd. The diameter of the circle is the same as the shorter length in the rectangle, 26. Therefore,
C = (3.14)(26) so
C = 81.64 m for a whole circle, and for half of that circle, the circumference is
C = 40.82 m
Now we can find the perimeter of the rink:
40.82 + 61 + 26 + 61 = p so
p = 188.82 m
If the fencing costs $6.20 per meter and we have 188.82 m, then the total cost is
. The label "meter" cancels out, leaving us with
cost = $1170.82
10+5x=50
subtract ten from both sides
5x=40
divide five from both sides
x=8
