Answer:

234.85

Step-by-step explanation:

This was easy!!!

(The gardener comes 4 times a month... so divide 85.40 by 4 and you will get 21.35. Each time he comes, he gets 21.35 and by the end of the month, he has 85.40. It says he already came 11 times. So 4 + 4 = 8 + another 4 that equals 12. He came only two months and a few weeks. This means multiply 85.40 by 2 so you would get 170.8. It said he came 11 times so substract 11 from 8 and you would get 3. So multiply 21.35 by 3 and get a total of 64.05. Add 170.8 and 64.05 to get 234.85!!! The answer is 234.85 or C!!!!

6 children need to share 5 breakfast bars Divide bars into correct numbers of equal parts then tell the fraction each kid will g

tigry1 [53]

-- Carefully cut <em>each bar into 6 equal pieces</em>.
   There are (5 x 6) = 30 pieces all together.
   Each piece is 1/6 of a bar.

-- Each child gets 5 of the pieces.
   That's the same as <em>5/6 of a whole bar</em>.
   (6 children) x (5 pieces) = 30 pieces. It works out. yay !

What is a8 for the geometric sequence 6,561;−2,187;729;−243;…6,561;−2,187;729;−243;….

VMariaS [17]

Consider a geometric sequence $(u_n)$

let $u_1=a$ and the common ratio be r, then the sequence is constructed as follows:

$u_1, u_2, u_3..... = a, ar, a r^{2}, a r^{3}, ...$

we can observe that each term of the sequence is its previous term * r.

In the given sequence, to find the common ratio we divide 6,561 by −2,187 and get -3. This means that $r= -\frac{1}{3}$

Let the first term $u_1=a=6,561$ ,

then the eighth term is

$u_8=a* r^{7}= 6,561 (- \frac{1}{3} )^{7}= -6,561*( \frac{1}{3} )^{7}= \frac{-6,561}{2187} =-3$

Answer: -3
