Answer:

x= 119.4

Step-by-step explanation:

Let's solve your equation step-by-step.

x + 5.8= 125.2

Step 1: Subtract 5.8 from both sides.

x + 5.8 − 5.8 = 125.2 − 5.8

x = 119.4

It takes a hose 5 minutes to fill a rectangular aquarium 11 inches long, 13 inches wide, and 14 inches tall. how long will it ta

Karolina [17]

Volume of 1st aquarium = 11 * 13 * 14 = 2002
volume of 2nd aquarium = 21 * 14 * 30 = 8820

if 5 minutes = 2002
1 minute = 2002\5 = 400.4

minutes to fill the 2nd aquarium is 8820/400.4 = 22.028(approximately)

Find S^20 if the series 1 + 1.1 ..... is a (a) arithmetic (b) geometric

quester [9]

I'm guessing S^20 is actually referring to the 20th partial sum $S_{20}$ , with

$S_{20}=1+(1+1\times0.1)+(1+2\times0.1)+\cdots+(1+18\times0.1)+(1+19\times0.1)$

in the arithmetic case, and

$S_{20}=1+1.1+1.1^2+\cdots+1.1^{18}+1.1^{19}$

in the geometric case.

(a) Combining like terms, we have

$S_{20}=20+0.1(1+2+\cdots+18+19)$

and invoking the formula

$1+2+\cdots+(n-1)+n=\dfrac{n(n+1)}2$

we end up with

$S_{20}=20+0.1\dfrac{19\times20}2=39$

(b) Multiply $S_{20}$ by 1.1, then subtract this from $S_{20}$ :

$1.1S_{20}=1.1+1.1^2+1.1^3+\cdots+1.1^{19}+1.1^{20}$

$S_{20}-1.1S_{20}=-0.1S_{20}=1-1.1^{20}$
$\implies S_{20}=\dfrac{1.1^{20}-1}{0.1}\approx57.275$
