Nikitich [7]

Answer:

z (min ) = 0.4167 $

x = 8,33 oz

y = 0

Step-by-step explanation:

Table:

Vitamin A Vitamin B Cost $/oz

Wheat (x) 10.5 2.4 0.05

Oats (y) 6 1.8 0.10

Requirements 48 (mg) 20 (mg)

Requirements 1,693 (oz) 0,7054 (oz)

The problem is minimized z subject to two constraint

z = 0.05*x + 0.1*y to minimize

Subject to:

Requirement of Vitamin A

10.5*x + 6 * y ≥ 48

Requirement of Vitamin B

2.4*x + 1.8*y ≥ 20

x≥0 y≥0

Using the on-line solver AtomZmaths and after 3 iterations the solution is:

z (min ) = 0.4167 $

x = 8,33 oz

y = 0

You paint 1313 of a wall in 1414 hour. At that rate, how long will it take you to paint one wall?

Serhud [2]

<span>You paint 1313 of a wall in 1414 hour.
Now we need to find the rate in order you to paint one wall.

1313 : 1414 = 1 : X
1414 = 1313 X
X = 1.08

So the rate per one wall is 1.08 hours.</span>

The price of a cup coffee was 2.40 yesterday. Today, the price fell to 2.15 find the percentage decrease. Round the answer to th

irakobra [83]

ANSWER

The percentage decrease is 10.4%.

EXPLANATION

To calculate percentage decrease, use the formula,

Percentage decrease

$= \frac{new \: price - old \: price}{old \: price} \times 100\%$

Yesterday the price of coffee was 2.40. This is the old price.

Today the price is 2.15. This is the new price.

$= \frac{2.15 - 2.40}{2.40} \times 100\%$

$= \frac{ - 0.25}{2.40} \times 100\%$

$= - 0. 10416667 \times 100\%$

$= - 10.416667\%$

To the nearest tenth, we have:

$- 10.4\%$

Therefore the percentage decrease is 10.4%.
