Given that amount of first acid solution = 4 liters

Let concentration of the first acid solution = x

then effective amount of first solution = 4x


Given that amount of second  acid solution = 10 liters

Givn that concentration of the second acid solution = 40% = 0.4

then effective amount of second solution = 0.4(10)


Then amount of resulting acid solution = (4+10) liters

Givn that concentration of the resulting acid solution = 30% = 0.3

then effective amount of resulting solution = 0.3(4+10)


Combining all those results gives equation

4x +0.4(10) = 0.3(4+10)

4x +4 = 0.3(14)

4x +4 = 4.2

4x = 0.2

x=0.05


Hence final answer is 0.05 or you can say 5%.

Using the following image, solve the problems below given that B is the midpoint of AC.
ladessa [460]

Answer:

AB = 4

BC = 4

AC = 8

Step-by-step explanation:

Given, B is the midpoint of AC which means it divided the AC into two equal parts. Using this information we can write the following equation:

5x - 6 = 2x add 6 to both sides

5x = 2x + 6 subtract 2x from both sides

3x = 6 divide both sides by 3

x = 2 to find the length of AB, AC, and BC replace x with 2

AB = 5*2 - 6

BC = 2*2

AC = 8 (sum of AB and BC)

Which set of transformations is needed to graph f(x) = -0.1cos(x) - 4 from the parent cosine function?
Ostrovityanka [42]

Answer:

The correct option is;

Reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down

Step-by-step explanation:

The given function is f(x) = -0.1·cos(x) - 4

The parent cosine function is cos(x)

Therefore, f(x) = -0.1·cos(x) - 4 can be obtained from the parent cosine function as follows;

The negative sign in the function gives a reflection across the x-axis

The 0.1 factor of the cosine function gives a compression of 0.1

The constant -4, gives a vertical translation 4 units down

Therefore, the correct option is a reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down.
