Answer:

1:4

Step-by-step explanation:

<u>Let it be:</u>

  • 30% solution = x
  • 5% solution  = y

then

  • 10% solution = x + y

----------

<u>Amount of acid:</u>

  • 0.3x + 0.05y = 0.1(x+y)
  • 0.3x + 0.05y = 0.1x + 0.1y
  • 0.2x = 0.05y
  • 20x = 5y
  • 4x = y
  • x/y = 1/4

So the ratio of 30% solution to the 5% solution is 1:4

Answer:

  1 : 4

Step-by-step explanation:

For a problem of this nature, a simple diagram makes the solution trivially easy. In the attached, the constituent concentrations are listed on the left, the solution concentration is in the middle, and the numbers on the right are the differences along the diagonals. These are the ratios of the respective solutions on the left.

That is, the ratio of 30% solution to 5% solution is 5 : 20 or 1 : 4.

Two vertical angles are expressed as (1/2)x+12 and (3/4)x+8. Find the value of x.
JulijaS [17]

Answer:

x = 16

Step-by-step explanation:

Since vertical angles are equal, we can set these two expressions equal to each other to solve for x:

(1/2)x + 12 = (3/4)x + 8

12 = 0.25x + 8

4 = 0.25x

16 = x

James will need 180 cubic feet of concrete. The concrete mix delivery truck driver wants the order in cubic yards. How many cubi
Lesechka [4]
We determine the number of cubic yards that James need to order by converting the unit of measurement given in feet to yards. Every yard is composed of 3 feet. Thus, the solution would be,
       (180 ft)³ x (1 yd/ 3ft)³ = 6.67 yd³
Thus, James will have to order 6.67 yd³.
