When you roast coffee, it loses 12% of its weight. how much fresh coffee do you need in order to get 14 2/25 lb of roasted coffe
Komok [63]

Answer:

16 lb of fresh coffee.

Step-by-step explanation:

Let  x pound be the  amount of fresh coffee needed.

100 - 12 = 88%  is equivalent to 14 2/25  of roasted coffee.

By proportion  x = 14 2/25  /  88/100

= 352 / 25 * 100/88

= 35200 / 25 * 88

= 16 lb  (answer).

Answer:

diagonal = = 12.8 inches (to the nearest tenth of an inch)

Step-by-step explanation:

As shown in the diagram attached to this solution:

Let the Length of the rectangular board = a

Let the width = b

Let the diagonal = d

where:

a = 10 inches

b = 8 inches

d = ?

Triangle ABC in the diagram is a right-angled triangle, therefore, applying Pythagoras theorem:

(hypotenuse)² = (Adjacent)² + (Opposite)²

d² = 10² + 8²

d² = 100 + 64

d² = 164

∴ d = √(164)

d = 12.806 inches

d = 12.8 inches (to the nearest tenth of an inch)

<em>N:B Rounding off to the nearest tenth of an inch is the same as rounding off to 1 decimal place.</em>
