Answer:

12%

Step-by-step explanation:

First, find how much salt is in each solution by multiplying the total amount by the percent of salt:

10(0.15)

= 1.5

15(0.1)

= 1.5

Added together, there are 3 pints of salt. There is a total of 25 pints, since 10 pints and 15 pints were mixed.

Find the concentration of salt by dividing 3 by 25

3/25

= 0.12

So, the concentration of salt in the solution is 12%

Geometry please help. What is the perimeter of XYZ

Morgarella [4.7K]

Answer:

Step-by-step explanation:

Angle AQC, AQB and BQC are 120deg. (360/3=120). Therefore, Angle BZC, CXA and AYB are 60deg. Because, angle BZC is half of angle BQC. same for the other three angles. As, all 3 angles are 60deg, it is an equilateral triangle. So, YZ is 13 therefore as all 3 sides are equal its 13*3=39.
