How to get the lateral area of a rectangular prism? Plz Explain

Keith_Richards [23]

If by lateral area you mean the total surface of the rectangle :

each side appears twice so the total area A will be

A=2(length*width+width*height+height*length)=16*8+8*4+4*16
A=224

If you meant lateral area as in the total area minus the top and bottom base:
A=2(width*height+height*length)=8*4+4*16=96

Elsa took out a $6000 loan for 5 months and was charged simple interest. The total interest she paid on the loan was $195. As a

vivado [14]

Answer:

the annual rate of interest is 7.8%

Step-by-step explanation:

The computation of the annual rate of interest is as follows:

As we know that

Simple interest = Principal × rate × time

$195 = $6,000 × rate × 5 months ÷ 12 months

$195 = 25 × rate

Rate = $195 ÷ 25

= 7.8%

Hence, the annual rate of interest is 7.8%

We simply applied the above formula so that the correct value could come

And, the same is to be considered

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.
