Answer:
9 days
Step-by-step explanation:
8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)
(2) x 2:
10 x - 6y = 4.4 --------(2a)
(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73
There is 1 set of solution to it. (Answer C)
Answer:
<h2>69.124 yards of rope</h2>
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, circles.
given that the members of the community used rope as outline for the circular shape mural.
we can tell that the perimeter of the mural is same as the perimeter of the rope.
Hence the length of rope used is same as the perimeter of the circular mural.
we know that the perimeter of a circle is given as
substituting radius r= 11 yards
we have
I suppose the third term should say -10/3, not -103.
Notice that
-2 = -6/3
-4 = -12/3
so that, starting with the first term <em>a</em>(1) = -6/3, the every following term is obtained by subtracting 2/3.
-2 - 2/3 = -6/3 - 2/3 = -8/3
-8/3 - 2/3 = -10/3
-10/3 - 2/3 = -12/3 = -4
and so on.
So the recursive rule is
<em>a</em>(1) = -2,
<em>a</em>(<em>n</em> + 1) = <em>a</em>(<em>n</em>) - 2/3, for <em>n</em> ≥ 1
or C.
Less because l don't be yelling at me what's wrong wit you.
