Find how many quarts of 6% butterfat milk and 1% butterfat milk should be mixed to yield 75 quarts of 3% butterfat milk.

IgorC [24]

Answer:

30 gallons of 6% milk, and 45 gallons of 1% milk.

Step-by-step explanation:

x=quarts of 6% butterfat

<h2>First, write an equation.</h2>

0.06x+0.01(75-x)=0.03*75

<h2>Multiply both sides by 100.</h2>

0.06x*100+0.01*100(75-x)=100*0.03*75

<h2>Simplify</h2>

6x+75-x=3*75

6x+75-x=225

<h2>Solve</h2>

5x=225-75=150

5x=150

x=30

75-30=45

So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.

F(x)=4x-3<br> G(x)=x^3+2x<br> Find (f-g)(x)

dexar [7]

You gotta remember that $(f-g)(x)$ means $f(x) - g(x)$ .

So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3

PLS ANSWER ASAP FIRST ONE TO DO SO GETS BRAINLIEST

Answer:

Carmen can make $10\frac{5}{16}$ full servings.

Step-by-step explanation:

Given : Carmen mixes $3\frac{1}{2}$ cups of water with $3\frac{3}{8}$ cups of juice to make punch.

Total quantity of punch Carmen made = total cup of water + cup of juice she mixes

Total quantity of punch Carmen made = $3\frac{1}{2}+3\frac{3}{8}$

Solving , we get,

Total quantity of punch Carmen made = $\frac{7}{2}+\frac{27}{8}$

taking LCM(2,8) = 8 , we get,

Total quantity of punch Carmen made = $\frac{28+27}{8}=\frac{55}{8}$

Also, given She pours $\frac{2}{3}$ cup servings of punch.

Thus, $\frac{2}{3}$ cup of mixture makes 1 serving cup.

Using unitary method,

In unitary method we first find the value of a single quantity and then multiply it with the desired quantity.

1 cup of mixture makes $\frac{3}{2}$ serving cup.

$\frac{55}{8}$ cup makes = $\frac{3}{2}\times\frac{55}{8}$

$\frac{55}{8}$ cup makes = $\frac{165}{16}=10\frac{5}{16}$

Thus, She can make $10\frac{5}{16}$ full servings.
