Let 
be the number of liters of the 10% solution she needs to use. She'd end up with a 6% solution with a volume of 
liters. The starting solution contains 0.04*9 = 0.36 liter of salt. Each liter of the 10% solution contributes 0.1 liter of salt, so that
Solve for :
so Mayra needs to add 4.5 liters of the 10% solution.
Answer:
Angle 1 = 41°
Step-by-step explanation:
Since they are both vertical angles
(6x+11)° = (10x-9)°
6x - 10x = -9 - 11
-4x = -20
4x = 20
x= 5.
Therefore,
Angle 1 = 6(5) + 11
Angle 1 = 30 + 11
Angle 1 = 41°
Answer:
(-5,24)
Step-by-step explanation:
2f+3g-h
first we substitute in the numbers
2(-3)+3(1)-2
-6+3-2
-3-2
-5
Then again
2(5)+3(4)-(-2)
10+12+2
22+2
24
hope this helps!:)
Answer:
C) x = 8√3 ; y = 4√3
Step-by-step explanation:
In this figure, the triangle is 30°-60° right triangle.
So x/12= 2/√3, y/12 = 1/√3
