40.82 kg beacause one kg is 2.20462 pounds so if you add all that together it all adds up to that.

1 kg = 2.2 lb
to set up your proportion
- put your given over one
90lb / 1
then multiply that by you conversion factor which is 1 kg = 2.2 lb
90lb/1 x 1kg/2.2lb
since you have lb on both the top and bottom that unit would cancel out leaving you with kg
if you multiply straight across you get 90 x 1 = 90 and 1 x 2.2 = 2.2
now you just divide the top number by the bottom number 90 ÷ 2.2 = 40.91 kg

Identify whether the series sigma notation infinity i=1 15(4)^i-1 is a convergent or divergent geometric series and find the sum

const2013 [10]

Answer: The correct option is

(d) This is a divergent geometric series. The sum cannot be found.

Step-by-step explanation: The given infinite geometric series is

$S=\sum_{i=1}^{\infty}15(4)^{i-1}.$

We are to identify whether the given geometric series is convergent or divergent. If convergent, we are to find the sum of the series.

We have the D' Alembert's ratio test, states as follows:

Let, $\sum_{i=1}^{\infty}a_i$ is an infinite series, with complex coefficients $a_i$ and we consider the following limit:

$L=\lim_{i\rightarrow \infty}\dfrac{a_{i+1}}{a_i}.$

Then, the series will be convergent if L < 1 and divergent if L > 1.

For the given series, we have

$a_i=15(4)^{i-1},\\\\a_{i+1}=15(4)^i.$

So, the limit is given by

$L\\\\\\=\lim_{i\rightarrow \infty}\dfrac{a_{i+1}}{a_i}\\\\\\=\lim_{i\rightarrow \infty}\dfrac{15(4)^i}{15(4)^{i-1}}\\\\\\=\lim_{i\rightarrow \infty}\dfrac{15(4)^i}{15(4)^{i}4^{-1}}\\\\\\=\dfrac{1}{4^{-1}}\\\\=4>1.$

Therefore, L >1, and so the given series is divergent and hence we cannot find the sum.

Thuds, (d) is the correct option.

A chemist is using 342 milliliters of a solution of acid and water. If 14.4% of the solution is acid, how many milliliters of ac

Irina-Kira [14]

Answer:

47.88milliliters

Step-by-step explanation:

Given data

Total amount of the solution= 342 milliliters

14% is acid

Hence the amount of acid

=14/100* 342

=0.14* 342

=47.88milliliters

Therefore there are 47.88milliliters of acid
