Answer:
10 quarts of 5% with 20 quarts of 2% buttermilk
Step-by-step explanation:
x + y = 30 where x = volume of 5% and y = volume of 3%
0.05x + 0.02x = 0.03(x + y)
0.02x - 0.01y = 0 Multiply through by 100
2x - y = 0
Add the above equation to the first equation:-
3x = 30
x = 10
so y = 30-10 = 20
Answer:
The slope of an equation perpendicular to this one would be 2/3.
Step-by-step explanation:
In order to find this, we need to first find the slope of this line. We do this by solving for y.
-2y = 3x + 7
y = -3/2x - 7/2
Now we know the slope is -3/2. In order to find the perpendicular slope, we first flip the equation. So -3/2 becomes -2/3. Then we change the sign. So -2/3 becomes 2/3. This will be the new slope.
Answer:
10.2
Step-by-step explanation:
Using Pythagoreans theorem, i did A^2 + B^2 = C^2
in this case,
4^2 + x^2 = 11^2
16 + x^2 = 121
x^2 = 105
square root both sides
you get 10.2469508
or 10.2
