Identify whether the series summation of 8 open parentheses 5 over 6 close parentheses to the i minus 1 power from 1 to infinity

Leto [7]

$\displaystyle\sum_{i=1}^\infty\8\left(\dfrac56\right)^{i-1}$

This is a geometric series with a common ratio between successive terms that is less than 1 in absolute value. This means the series will converge. The value of the sum is $\dfrac8{1-\frac56}=48$ .

Given that the two triangles are similar, solve for x if AU = 20x + 108, UB = 273, BC = 703, UV = 444, AV = 372 and AC = 589.

777dan777 [17]

If two triangles are similar then the corresponding sides are in proportion. Thus,

AB / AU = BC / UV = AC / AV

AB / (20x+108) = 703 / 444

Where AB is equivalent to:

AB = AU + UB

AB = 20x + 108 + 273

AB = 20x + 381

Therefore going back to the first equation:

(20x + 381) / (20x + 108) = 703/444

444 (20x + 381) = 703 (20x + 108)

8880x + 169164 = 14060x + 75924

14060x - 8880x = 169164 – 75924

5180 x = 93240

x = 93240 / 5180

x = 18 (ANSWER)

Lavita finally got her beautiful painting done it was a total of 1 2/3 meters. She was able to finish 3/8 each week. how many we

Paul [167]

Answer:

4 weeks

Explanation:

Length of Lavita’s painting = $1 \frac{2}{3} m=\frac{5}{3} m$

Length she was able to finish each week= $\frac{3}{8}m$

Now,

If she is able to finish $\frac{3}{8}m$ in 1 week

Then

$\frac{3}{8}m$ = 1 week

1 m = $\frac{8}{3}m$ week

Therefore

$\frac{5}{3} m=\frac{8}{3} \times \frac{5}{3} \text { week }$

= $\frac{40}{9}$ week

=4.44 week

= 4 weeks (approx.)
