Answer:
The percentage of fat in the mixture is 8%
Step-by-step explanation:
Let
x -----> the percentage of fat in the mixture
we know that
The volume of milk multiplied by its percentage of fat plus the volume of cream multiplied by its percentage of fat must be equal to the total volume of he mixture multiplied by the percentage of fat in the mixture
Remember that
15%=15/100=0.15
3%=3/100=0.03
so
Solve for x
Convert to percentage
Step-by-step explanation:
[Taking a common from each term]
Hence,
16y^3 + 9x^2y - 54x = 0
16*3y* dy/dx + 9x^2* dy/dx + 18xy - 54 = 0
dy/dx = = (54 - 18xy) / (48y + 9x^2)
I have to go I can do the second part later
23/30 can't be simplified any further because 23 is a prime number.
Answer:
x = 8
Step-by-step explanation:
Diagonals of a kite cross at right angles. That gives us a relation that can be solved for x.
<h3>Setup</h3>
The measure shown is equal to the angle measure of 90°.
14x -22 = 90
<h3>Solution</h3>
We can solve this 2-step linear equation in the usual way.
14x = 112 . . . . . . step 1, add the opposite of the constant to get x alone
x = 112/14 = 8 . . . step 2, divide by the coefficient of x
The value of x is 8.
