Nelly owns farm land that has an area of 4.2 × 102 acres. Each year, the farm produces 6.72 × 104 bushels of corn. What is the a

juin [17]

The average amount of corn produced per acre represented in scientific notation can be found using the below formula:

$The \;average\; amount\; of\; corn\; per\; acre=\frac{Bushels \; of\; corn\; produced\; in\; farm}{Area\; of\; farm\; in\; acres}$

We are given:

$Area \; of\; FARM\; land= 4.2 \times 10^2 \; acres\\ \\ Amount \; of\; corn\; produced=6.72\; \times \; 10^4 \; bushels$

Substituting the above information in the formula, we get...

$The \; Average\; amount\; of\; corn=\frac{6.72 \times 10^4}{4.2 \times 10^2} \\ \\ \frac{6.72}{4.2} \times \frac{10^4}{10^2}\; =\; 1.6 \times 10^{4-2}\; =\; 1.6 \times 10^2\\ \\$

Conclusion:

$The \; Average \; amount\; of \; corn \; is\; 1.6 \times 10^2 \; Bushes\; per\; corn$

The average amount of corn produced per acre represented in scientific notation is option B) $1.6 \times 10^2$ bushels per acre

the price for dinner in a resteraunt was $80. The customer paid an addition 7% meals tax and left a $15 tip. how much meals tax

Marrrta [24]

Multiply the price of the meal by the sales tax. Tips are added in after tax has been applied, so it would not be added in to calculate the tax.

Tax= Meal Cost * Tax %

=$80 * 7%
convert % to decimal (7% ÷ 100)

=80 * 0.07

=$5.60 sales tax paid

ANSWER: $5.60 was the sales tax the customer paid.

Four times the lesser of two consecutive even integers is 12 less than twice the greater number. Find the integers.

pashok25 [27]

Oh, this one lol. ok
you gotta read it like its a book.
4 x s(i picked that variable) which is 4s together

4s+12 (if they said'12 less than' then the 12 gotta be adding.)
then u have to divide it so its going to look like this:

4s+12= blah blah blah
'twice the greater number' means you gotta do this: 2(s+2)

so the problem is this: 4s+12=2(s+2)

now you solved it and the answer will beeeeee s=-4

Use calculus to find the largest possible area for a rectangular field that can be enclosed with a fence that is 400 meters long

Setler79 [48]

the largest rectangular area is actually a square.

so the side would be 400/4 = 100 feet

area of a square is S^2

100^2 = 10,000 square feet
