How much salt is in a mixture containing 10 gallons of an 11% salt solution and 6 gallons of a 7% salt solution?
I think I can solve it but forming the equation is where I have problems.​

Answers

Answer 1

Answer:

Step-by-step explanation:

There really isn't an equation because there isn't an unknown. If we create a table, the "equation" that you are talking about will be come apparent. Let's call the 2 solutions Sol 1 and Sol 2:

                      Gallons of solution    *        % salt          =         Gallons of salt

Sol 1  

Sol 2

If we fill in this table according to the info we are given, we have 10 gallons of the 11% solution, and 6 gallons of the 7% solution, so

                     Gallons of solution       *       % salt         =        Gallons of salt

Sol 1                        10                                     .11            =        1.1 gallons of salt

Sol 2                        6                                     .07           =        .42 gallons of salt

We multiply the Gallons of solution by the % salt to get the gallons of salt. There are 1.1 gallons of salt in solution 1 and .42 gallons of salt in solution 2, so in the mixture (which is 16 gallons) there is 1.1 + .42 gallons of salt, which is 1.52 gallons of salt.

Given the triangle that has a base of five less than triple the height. The height is 2x+6.




Part A: Determine the expression that represents that area of the triangle.

Answers

Answer:

         A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78

Step-by-step explanation:

H = 2x+6          - the hight

3H = 3(2x+6)      - triple the hight

3H-5 = 3(2x+6) - 5    -  five less than triple the height

Area of triangle:  A = 0.5BH

B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13

H = 2x+6

So:

    A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78

    A = 6x² + 49x + 78

area of rectangle = l*b

                         =     (3x-y+4) ( X+7)

                       = 3x²-xy + 4x+21x-7y+28

                       = 3x²-xy +25x-7y +28

Area of square = l²

                        = (x-2)²= x²- 4x +4

area of shaded region=( 3x²-xy +25x-7y +28) -(x²- 4x +4)

                                     =2x²-xy +29x-7y+24

b²-4ac = (-23)²- 4×1×130 = 529 -520 = 9>0

if solutions (A=x₁, B=x₂) exist (b²-4ac≥0) then based on vieta's formula:

Answers

Answer:

1,700 MG

Step-by-step explanation:

1, 360 / 2 = 40% of the daily amount since 20% is taken from the beans.

1360 / 2 = 680

680 (40%) / 2 = 340, which is 20%.

The answer is D, -11 degrees.  

Step-by-step explanation:

Angle RQP is total sum of angles RQU, (96 + x) and UQP, (x + 57).  

Angle RQP = 131.  

(96 + x) + (x + 57) = 131

153 + 2x = 131

2x = -22

x = -11.  

Therefore, answer is -11 degrees.

Define the variables that you use to write the system.

Answers

Answer:

x = 2y --------(1)

75x + 250y = 800 ---------(2)

Step-by-step explanation:

Let the number of chicken wings be x

And the number of sliders be y

x = 2y --------(1)

75x + 250y = 800 ---------(2)

The system of equation is x = 2y and 75x + 250y = 800.

Important information:At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. here we assume the number of chicken wings be x and number of sliders be y
