How much cream that is 30% butterfat must be mixed with milk that is 3% butterfat to make 45 gal of cream that is 12% butterfat?

pochemuha

Answer:

15 gallons

Step-by-step explanation:

If x is the gallons of 30% butterfat cream, and y is the gallons of 3% butterfat milk, then:

x + y = 45

0.30 x + 0.03 y = 0.12 (45)

Solve the system of equations with substitution or elimination. Using substitution:

0.30 x + 0.03 (45 − x) = 0.12 (45)

0.30 x + 1.35 − 0.03 x = 5.4

0.27 x = 4.05

x = 15

You need 15 gallons of 30% butterfat cream.

Answer:

sin(B) = 2/3

Step-by-step explanation:

The law of sines tells you the sine of an angle is proportional to the length of the opposite side.

sin(B)/b = sin(A)/a

sin(B)/8 = sin(30°)/6 . . . . fill in the given values

sin(B) = 8(1/2)/6 . . . . . . . .multiply by 8

sin(B) = 2/3

A Chef prepares and evenly divides s ounces of beef stock into 3 smaller pans. The chef uses 8 ounces of beef stock form one of

saw5 [17]

Answer:

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

The total number of ounces of beef stock = 126

Step-by-step explanation:

Given:

Total ounces of beef stock = $s$

The chef divided the beef stock evenly into 3 smaller pans.

The chef then uses 8 ounces from one of the smaller pans.

Ounces of beef stock left in the smaller pan = 34

Solution:

Total ounces of beef stock = $s$

Ounces of beef stock in each smaller pan = $\frac{s}{3}$

Ounces of beef stock used by the chef from the smaller pan = 8.

The ounces of beef stock left in the smaller pan will be given as:

⇒ $\frac{s}{3}-8$

Ounces of beef stock remaining in smaller pan = 34

Thus, the equation hat correctly represents the number of ounces of beef stock, $s$ , that the chef initially prepares.

⇒ $\frac{s}{3}-8=34$

Solving for $s$ .

Adding 8 both sides.

⇒ $\frac{s}{3}-8+8=34+8$

⇒ $\frac{s}{3}=42$

Multiplying both sides by 3.

⇒ $3\times \frac{s}{3}=42(3)$

∴ $s=126$

Thus, total number of ounces of beef stock = 126
