A builder purchases 600 bricks for a new residential construction. The dimensions of each brick are 5.1 cm by 10.2 cm by 20.3 cm

Blababa [14]

<h3>Answer:</h3>

1165.83 kg

<h3>Explanation:</h3>

The total mass is the product of volume of one brick, the number of bricks, and the density. For this problem, it is convenient to use dimensions in meters.

$(0.051\,m)(0.102\,m)(0.203\,m)(600)\dfrac{1840\,kg}{m^3}=(0.6336036\,m^3)\dfrac{1840\,kg}{m^3}\\\\=1165.83\,kg$

A farmer in Iowa owns 450 acres of land. He is going to plant each acre with wheat or corn. Each acre planted with wheat yields

Andrei [34K]

Answer:

each 200 acres.

Step-by-step explanation:

Here we are given 2000 profit for wheat per acre and 3000 profit per acre for corn.

Hence objective function to maximize is

$Z=3000W+2000C$

Where W is wheat cultivated and C, corn cultivated

Constraints are workers and acres

Total workers required = 3W+2C and total fertilizers = 2w+4c

$3W+2C\leq 1000\\2W+4C\leq 1200$

We solve and get corner points as

(W,C) = (333,0) (600,0) (0,500) (0,300)

Intersecting point is

by solving we get

2w = 400 or w =200 and c = 200

Thus feasible points are

(200,200) Or (333,0) or (0,300)

Z for I point = 1000000

Z for II point = 666000

Z for III point =900000

Maximum is when wheat and corn are 200 acres each planted.
