Answer:

Therefore the third container contains $\frac{735}{17}\%$ = 43.23 % acid.

Step-by-step explanation:

Given that, One container is filled with the mixture that 25% acid. 55% acid is contain by second container.

Let the volume of first container be x cubic unit.

Since the volume of second container is 55% larger than the first.

Then the volume of the second container is

$= (V\times \frac{100+55}{100})$ cubic unit.

$=\frac{155}{100}V$ cubic unit.

The amount of acid in first container is

$=V\times \frac{25}{100}$ cubic unit.

$=\frac{25}{100}V$ cubic unit.

The amount of acid in second container is

$=(\frac{155}{100}V \times \frac{55}{100})$ cubic unit.

$=\frac{8525}{10000}V$ cubic unit.

Total amount of acid $=(\frac{25}{100}V+\frac{8525}{10000}V)$ cubic unit.

$=(\frac{2500+8525}{10000}V)$ cubic unit.

$=(\frac{11025}{10000}V)$ cubic unit.

Total volume of mixture $=(V+\frac{155}{100}V)$ cubic unit.

$=\frac{100+155}{100}V$ cubic unit.

$=\frac{255}{100}V$ cubic unit.

The amount of acid in the mixture is

$=\frac{\textrm{The volume of acid}}{\textrm{The amount of mixture}}\times 100 \%$

$=\frac {\frac{11025}{10000}V}{\frac{255}{100}V}\times 100\%$

$=\frac{735}{17}\%$

Therefore the third container contains $\frac{735}{17}\%$ acid.

The width of a rectangle is equal to m cm, but it’s length is five times greater than the width. Find the area of the rectangle.

Irina18 [472]

Area of rectangle is $5m^{2}\ cm^{2}$

Step-by-step explanation:

Given,

Width of rectangle = m cm

As length is 5 times more than width;

Length of rectangle = 5m cm

Area of rectangle = Length x Width

$Area\ of\ rectangle = 5m*m\\Area\ of\ rectangle = 5m^{2} \\As\ length\ and\ width\ both\ are\ in\ cm\,\ therefore\\Area\ of\ rectangle = 5m^{2}\ cm^{2}$

Area of rectangle is $5m^{2}\ cm^{2}$

F(x)=2x^2+7x-5+g(x)=-8x^2-3x+5<br><br> what is g(x) + f(x)

Licemer1 [7]

F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5

g(x) + f(x)
-8x² - 3x + 5 + 2x² + 7x - 5
-8x² + 2x² - 3x + 7x + 5 - 5
-6x² + 4x + 0
