A coffee mixture contains beans that sell for $0.08 per pound and $0.32 per pound. If 110 pounds of beans create a mixture that

garik1379 [7]

Answer:

B = 87.08 pounds @ $0.32

A = 22.92 pounds @ $0.08

Step-by-step explanation:

given,

cost of beans (A)= $ 0.08/pound

and another beans cost (B) = $ 0.32 /pound

total weight of the pound = 110 pound

selling price of mixture = $ 0.27/pound

cost of each bean = ?

A + B = 110

A = 110 - B-------(1)

0.08 A + 0.32 B = 0.27 x 110

0.08 A + 0.32 B = 29.7

Putting value of A

0.08(110 - B) + 0.32 B = 29.7

8.8 - 0.08 B + 0.32 B = 29.7

0.24 B = 20.9

B = 87.08 pounds @ $0.32

A = 22.92 pounds @ $0.08

Proportion problems

An example is:

y is directly proportional to x such that: y=4 when x = 2;

Derive the equation

For direct proportions, we have:

$y\ \alpha\ x$

This gives:

$y = kx$

Make k the subject

$k = y/x$

So:

$k = 4/2 =2$

So, the equation is:

$y = kx$

$y = 2x$

Assume the above question is for inverse proportion

The variation will be:

$y\ \alpha\ \frac{1}{x}$

This gives:

$y\ = \frac{k}{x}$

Make k the subject

$k =x*y$

$k =2* 4 = 8$

So, the equation is:

$y\ = \frac{k}{x}$

$y = \frac{8}{x}$

Solve for L:<br> P=2L+2W

Korvikt [17]

Answer:

$L=\frac{1}{2}P-W$

Step-by-step explanation:

Let's solve for L.

$P=2L+2W$

Step 1: Flip the equation.

$2L+2W=P$

Step 2: Add $-2W$ to both sides.

$2L+2W+-2W=P+-2W$

$2L=P-2W$

Step 3: Divide both sides by $2$ .

$\frac{2L}{2}=\frac{P-2W}{2}$

$L=\frac{1}{2}P-W$

Answer:

$L=\frac{1}{2}P-W$
