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).

They will rest after they hike `2` miles. Then they will hike the remaining `1.75` miles to the lookout. The trail the hikers wi
Lyrx [107]

Answer:

1.75 gallons

Step-by-step explanation:

First, we need to calculate how far the hike is going up the trail. They first hike 2 miles and then another 1.75 miles after resting so...

2 + 1.75 = 3.75 miles

The trail is 3.75 miles long, the question states that the return path is 0.5 miles shorter, therefore...

3.75 - 0.5 = 3.25 miles

Leaving us with a total hiking distance of

3.75 + 3.25 = 7 miles.

Since each hiker will carry 0.25 gallons for each mile we simply need to multiply this amount by the total number of miles in the hike.

7 * 0.25 = 1.75 gallons

Finally, we can see that each hiker will carry a total of 1.75 gallons of water for the entire hike.
