Amy wants to fence off a rectangular area that is 24 feet squared in size for a vegetable garden.
She is considering three garden lengths of 6 ft, 8 ft, and 12 ft. She wants to determine which garden would require the least amount of fencing.
Determine the dimensions of the garden that would require the least amount of fencing.

Length
12, 8, or 6ft
Width:
3, 4, or 2ft

Answer: 4

Step-by-step explanation: We can identify the number of significant digits by counting all the values starting from the 1st non-zero digit located on the left. For example, 12.45 has four significant digits.

The require answers are,

Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350

Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x

Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of the digital images and the permission = $125

“one time” charges = $3.25

Part a: The equation for the total cost of the calendars

THere are 100 calendars printed.

So, “one time” charge = 3.25*100

So, the total cost of the calendars C is given as,

C = 125 + 3.25*100

C = 125 + 325 = 450

Thus, the equation for the total cost of the calendars is given as,

C = 125 + 3.25*100 = 450

Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed

Let there are x calendars printed

Total “one time” charges = 3.25x

So, Average cost is given as,

A = 125 + 3.25x

this is the model that gives the average cost A per calendar

Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar

Now from the graph it must be seen that the average cost drops to $ 5 per calender at 70.

Thus, number of calendars that must be sold before the average cost drops to $5 per calendar = 70

Thus, the require answers are,

Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350

Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x

Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.

At present, the age of the woman is 29 years, while the age of her daughter is 6 years.

In the question, we are given two characters, a woman and her daughter, and told to find their present age. We are also given some clues as to how we will arrive at the answer. Let's consider the first one.

In the first sentence, we are told that 5 years ago, the woman was 4 times as old as her daughter. We don't know the woman's age or her daughter's, so let's call the woman's present age x and her daughter's present age y for now. To know the age of the woman 5 years ago, we will subtract 5 from her current age, which will give us x - 5. Also, the woman was 4 times as old as her daughter 5 years ago, hence:

                                    x - 5 = 4y

If we rearrange that;      x = 4y + 5 (let's call this equation 1)

Now, on to the second clue.

In the second sentence, we are told that in four years time, the woman will be two and a half times as old as her daughter. The woman's age in 4 years time is x + 4, hence:

                                 x + 4 = 2[tex]\frac{1}{2}[/tex]y

                                 x + 4 = 5y/2

                                 2x + 8 = 5y (let's call this equation 2)

Next, we will find the value of y (the daughter's present age) by substituting equation 1 into equation 2, that is, putting '4y + 5' in place of x in equation 2, thus:

                            2(4y + 5) + 8 = 5y

                            8y + 10 + 8 = 5y

                            8y - 5y = 18

                             3y = 18

                              y = 6

Therefore, at present, the daughter is 6 years old. To find the mother's age, we will substitute the daughter's age in place of y in equation 1:

                        x = 4y + 5

                        x = 4(6) + 5 = 29

Hence, the woman is 29 years old, and her daughter is 6 years old.

An equation of a line in slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept.

Given two points passed through by the line, you can use them to write the equation of the line in slope-intercept form.

1. Find the slope of the line using the two given points.

let Point 1(4 , 0) and Point 2(-3 , -7)

slope = m = (y2 - y1) / (x2 -x1)

m = (-7 - 0) / (-3 - 4)

m = -7/-7

m = 1

2. Use the value of the slope and one of the points to find the value of the y-intercept, b. Plug in these values in the formula for slope-intercept form.

y = mx+ b

y = 1x + b

Using Point 1,

Any of the basic arithmetic operations—addition, subtraction, multiplication, division, raising to the power of a whole number, and taking roots (fractional power)—is considered an algebraic operation. These procedures could be applied to numerical data, in which case they are frequently referred to as arithmetic operations. Similar operations can be carried out on variables, algebraic expressions, and, more generally, on components of algebraic structures like groups and fields. Another way to describe an algebraic operation is as a function from the Cartesian power of a set to the same set.

The given expression is 12(3/4)x - (1/2)y - 6(1/2)x - (3/4)y.

We have x = 2 and y = -2 as per the question.

To evaluate the expression, first we need to simplify the given expression and then we can substitute the given value of  x and y in simplified expression.

The given expression can be simplified as,

   12(3/4)x - (1/2)y - 6(1/2)x - (3/4)y

⇒ 9x - (1/2)y - 3x - (3/4)y
