3/5x=52 is the answer 120 or 130
postnew [5]
The direct answer to your question is: "No".
because in that equation, 'x' is not 120 or130.

Let's find out what 'x' actually is:

<u>3/5 x  =  52</u>

Multiply each side by  5 :      3x  =  260

Divide each side by  3 :       <em>  x  =  86 and 2/3 </em>

Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a 15% alcohol solut
Inessa05 [86]

The equation is 0.1x + 0.15(50-x)=1.20(50)

Step-by-step explanation:

Here you need 50ml of 12% alcohol solution.

You have 10% and 15% alcohol solutions.

Take volume of 10% alcohol solution to be x ml

Take volume of 15% alcohol solution to be y ml

Form equations;

x+y=50 ml--------------------------equation 1

0.1x +0.15 y= 12% of 50

0.1x+0.15y=6-----------------------equation 2

Now you have simultaneous equations, use a graph tool to solve for values of x and y as attached.

or use the mixture equation the get value of x

0.1x + 0.15(50-x)=1.20(50)

The values of x and y are ;

(x,y) (30,20) which means;

y is 20 ml of 15% alcohol

x is 30 ml of 10% alcohol

Manuel incorrectly claimed that the surface area of the cylinder shown is about 190.0 in.2. Use a formula to find the surface ar
Kitty [74]

Answer:

25.9%

Step-by-step explanation:

Note: you did not provide any attached image detailing the dimension of the cylinder however, let us arrange some dimension for explanation purpose

let the dimension of the cylinder be

radius= 3in

height= 5 in

Step two

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr2

substitute

T. S. A. =2*3.142*3*5+2*3.142*3^2

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

%error= actual -expected/expected*100

%error= 190 -150.816/150.816*100

%error= 39.184/150.816*100

%error= 0.259*100

%error= 25.9%

Now, you can use the dimension you have for the cylinder to calculate the total surface area, from there, you can solve for the error by following the steps above
