Given:

Total forest area = 43,000

Old growth trees forest = 0.2%

To find:

The area of the old growth trees.

Solution:

We have,

Total forest area = 43,000

Old growth trees forest = 0.2%

Area of the old growth trees = 0.2% of 43,000

                                               = \(\dfrac{0.2}{100}\times 43000\)

                                               = \(86\)

Therefore, the area of the old growth trees is 86 acres.

Answer:

Step-by-step explanation:

what i said above

The required maximum area of the rectangle is 17.5m

Given,

The perimeter of a rectangle is = 70m.

We have to find ,

The maximum area of rectangle .

A rectangle will have the maximum possible area for a given perimeter when all the sides are the same length. Since every rectangle has four sides, if you know the perimeter, divide it by four.

Then,

To find the length of each side. Then find the area by multiplying the length times the width.

Length is = 70m

Maximum area of rectangle is = \(\frac{perimeter}{4}\)

                                                    =  \(\frac{70}{4}\)

                                                    = 17.5

The required value of maximum area of the rectangle is 17.5m.

Answer:

The maximum area of one square plot is 144 \(m^2\)

Step-by-step explanation:

Start by looking at what are the greater common factor of both provided dimensions (840 and 396) to find what the numbers are they both can be divided by evenly:

\(840=2^3\,*\,3\,*\.5\,*\,7\\396=2^2\,*\,3^2\,*\,11\)

therefore, both numbers can be divided by \(2^2\,*\,3=12\)

Which then gives:

\(\frac{840}{12} =70\\\frac{396}{12} =33\)

Then, one can divide the longest side (840 m) into 70 sections of 12 meters each, and the shortest side of the piece of land (396 m) into 33 sections of 12 meters each.

Then we can have a total of 33 * 70 = 2310 smaller lots of 12 m by 12 m

That is smaller plots of a total area 144 square meters

ANSWER IS 12X-6

The stadium's profit margin will be $490,000 if it signs both acts to one-week deals.

Since each major circus act will perform for seven consecutive days, the stadium will have a total of 14 performance days (7 days for each act). Each performance provides a profit margin of $35,000 for the stadium. To calculate the stadium's profit margin if it signs both acts, we need to multiply the profit margin per performance by the total number of performances.

Profit per performance = $35,000

Total number of performances = 14 (7 days for each act)

To find the stadium's profit margin, we multiply the profit per performance by the total number of performances:

Profit margin = $35,000 * 14 = $490,000

Therefore, the stadium's profit margin will be $490,000 if it signs both acts to one-week deals. The correct answer is option C: $490,000.

The purpose of a variable is to hold and represent a value Option C.

The purpose of a variable in programming or mathematics is to hold and represent a value that can be assigned, changed, and used in various operations or calculations. Variables are fundamental components of programming languages and mathematical equations, enabling flexibility and dynamic behavior in computational tasks.

Option (c) "to hold a value" is the most accurate answer, as variables are used to store data or information in memory locations. This value can be of different types, such as integers, floating-point numbers, characters, or even more complex data structures like arrays or objects.

Variables allow programmers to work with and manipulate data efficiently. By assigning values to variables, we can reference and modify them throughout the program, making it easier to manage and organize information.

Variables also play a crucial role in performing calculations, as mentioned in option (b). We can use variables in mathematical expressions and algorithms to perform arithmetic operations, comparisons, and other computations. By storing values in variables, we can reuse them in multiple calculations and update them as needed.

While option (a) "to assign values" is a specific use case of variables, it is not the sole purpose. Variables not only store values but also facilitate data manipulation, control flow, and the implementation of algorithms and logic.

Option (d) "to hold a constant value" is incorrect because variables, by definition, can hold varying values. Constants, on the other hand, are fixed values that do not change during the execution of a program. Option C is correct.

Hello!

Lets go through each choice, and determine if it is correct.

So, the symbol ≤, means less than or equal to. So our answer must be less than -75 or -75 on the dot.

A: y = 75

Okay, so we can tell this one is wrong off the bat. 75 is much more than -75. (Make sure you notice the symbol!) So it cannot be equal to said answer. A is wrong.

B: y =-74

Another trick question! When you are in the negatives, less is more! So -74 is actually greater than -75. This is also incorrect!

C: y > -75

This one is straight forward. Our equation up top strictly says less than or equal too, while C says greater than. Incorrect!

D: y = -75

The last answer! We see that the symbol in our equation up top says less than or equal too, and y = -75 is equal. This is the correct answer.

Our correct answer is D: y = -75

Hope it was helpful.

It will take approximately 27 years to accumulate $100,000 in the savings account.

To calculate the time required, we can use the future value of an ordinary annuity formula. In this case, the annuity is the annual savings of $1,300, the interest rate is 5%, and the desired future value is $100,000. By plugging these values into the formula, we can solve for the number of periods (years) it will take to reach the target amount.

The formula is:

FV = P * ((1 + r)^n - 1) / r

Where FV is the future value, P is the annual payment, r is the interest rate, and n is the number of periods. Rearranging the formula to solve for n, we have:

n = log((FV * r / P) + 1) / log(1 + r)

Substituting the given values, we get:

n = log((100000 * 0.05 / 1300) + 1) / log(1 + 0.05)

Evaluating this expression, we find that n is approximately equal to 27. Therefore, it will take approximately 27 years to accumulate $100,000 in the savings account by saving $1,300 annually at an interest rate of 5%.

a) The regular expression "+" represents the language of one or more occurrences of the symbol "+". To construct a grammar that represents the same language but is not regular, we can use the following production rule:

S -> "+" S | "+".

This grammar generates strings with one or more "+" symbols.

b) The regular expression "+c" represents the language of one or more occurrences of the symbol "+" followed by the symbol "c". To construct a non-regular grammar for this language, we can use the following production rules:

S -> "+" S | "c".

This grammar generates strings with one or more "+" symbols followed by a "c". Since the language represented by the regular expression is regular, it can be recognized by a finite automaton. However, the grammar we constructed is not regular because it uses a recursive production rule.
