Assume that one day's labor in Argentina can produce either 20 units of cloth or 2 units of wine, while in Chile one day's labor

11111nata11111 [884]

Answer:

cloth production increase is 16 units

wine production increase is 8 units

Step-by-step explanation:

Given data

Argentina produce cloth = 20 units

Argentina produce wine = 2 units

chile produce cloth = 24 units

chile produce wine = 12 units

to find out

increase in combined output

solution

we know according to question Argentina transfers 2 units of labor from wine to cloth and Chile transfers 1 unit of labor from cloth to wine

therefore cloth production increase = Argentina produced total cloth - before transfer chile produce cloth ...........1

we can say that Argentina produced total cloth is 2 × 20 = 40 units

so from equation 1

cloth production increase = 40 - 24 = 16 units

cloth production increase is 16 units

and we now can say wine production increase = chile produce wine - before transfer Argentina produce wine .............2

so Chile produced total wine is 1 × 12 = 12 units

and Argentina produce wine with 2 units of labor (2 × 2) = 4

so from equation 2

wine production increase = 12 - 4 = 8 units

wine production increase is 8 units

Paladinen [302]

Answer:

quarters are 20 in number.

Step-by-step explanation:

Let d represent dimes

Let q represent quarters

d + q = 35

q = d+5

d+d+5=35

2d=35-5

2d =30

d = 30/2

therefore dimes =15

Substitute d for 15 to solve for q;

q=15+5

therefore quarters are 20 in number.

A swimmer dives 10 feet below the surface of a lake

AlexFokin [52]

Answer:

She must swim 10 feet before she reaches the surface; from level -10 to level 0 (Equation: $-10+10=0$ )

Step-by-step explanation:

Based on the information provided, you can assume that the surface of the lake is at level 0.

You know that the swimmer dives 10 feet below the surface; this is the level -10 .

This means that she must swim 10 feet from the level -10 to the level 0 in order to reach the surface of the lake.

Therefore, to find how far she must swim before she reaches the surface, it is necessary to add levels -10 and +10 to get the level 0. This can be represented with the following equation:

$-10+10=0$
