Answer: It doesn't really matter
Step-by-step explanation: This is more of an opinion question, but failing math tests doesn't mean you aren't good at math, some people have different reasons why they don't try at math. Math tests don't define how good or bad you really are in math. You can fail a math test and be good at math, but not passing math tests might also create a lot of issues in the careers you're trying to persuade in because math is one of the most useful subjects. If colleges see your math scores and how badly you performed in them, they won't pick you, which is why is always nice to try no matter how easy or hard it is.
The elementary school in your town wants to replace its current playground. The space used for the new playground will be similar to that of the current playground. The current space is rectangular and has a length of 35 feet and a width of 45 feet. The length of the new space is 42 feet. Find the perimeter of the space used for the new playground. Perimeter: feet
By answering the above question, we may infer that Thus, the 159 feet that make up the perimeter of the area used for the new playground.
What is perimeter?A limit is a closed path that encircles, separates, or encompasses a one-dimensional length, a two-dimensional shape. A circle's or an ellipse's perimeter refers to its outermost region. Many practical uses may be made of the perimeter calculation. The radius of an edge is used to calculate a shape's perimeter. Get the circle's radius by multiplying the lengths of the sides of irregular shapes. Every form's perimeter may be determined by multiplying its side lengths. The area around an object is called its perimeter. Your home's walled garden serves as a wonderful example of this. A thing's perimeter is the area surrounding it. A 200 foot barrier will be needed to contain a 50 by 50 foot yard.
Current playground size is 1,575 square feet, or 35 feet by 45 feet.
The difference between the old and new playgrounds is 1,575 square feet.
New playground length = 1,575 square feet / 42 feet 37.5 feet, where new playground width equals new playground area.
We can calculate the perimeter now that we know the new playground's width is around 37.5 feet:
The new playground's perimeter is equal to 2 (length + width).
The new playground's perimeter is 2 (42 feet plus 37.5 feet).
2 is the new playground's perimeter (79.5 feet)
The new playground's perimeter is 159 feet.
Thus, the 159 feet that make up the perimeter of the area used for the new playground.

Use the drawing tools to form the correct answ
Plot function / on the graph.
h(x)= {-4, x<-3
x+5, >-3
Answer:
I do not have access to drawing tools. However, I can describe how to plot the function on a graph.
To plot the function h(x) = {-4, x < -3 and x+5, x > -3, you would start by drawing the x-y axes on a coordinate plane. Then, you would mark a point at x=-3 on the x-axis. At this point, the value of h(x) changes from -4 to x+5. So, you would draw a solid dot at (-3, 2) on the graph.
Next, you would draw a horizontal line at y=-4 to the left of x=-3, indicating that h(x) is always equal to -4 for x values less than -3.
Finally, you would draw a diagonal line starting from the dot at (-3, 2) and continuing to the right. This line represents the equation x+5 for x values greater than -3.
The resulting graph should have a horizontal line at y=-4 to the left of x=-3, a solid dot at (-3, 2), and a diagonal line extending to the right from the dot.

A mean ogre stole 20
of your muffins 5/8 of all of them how many are left?
Answer:
Let's start by finding out how many muffins were there in total before the ogre stole 20 of them. Let's call that number "x".
If 5/8 of them were left after the ogre stole 20, then 3/8 of them were taken.
So we can set up an equation:
x - 20 = 3/8x
To solve for x, we can start by multiplying both sides by 8 to get rid of the fraction:
8(x - 20) = 3x
8x - 160 = 3x
Now we can solve for x by subtracting 3x from both sides:
5x - 160 = 0
5x = 160
x = 32
So there were originally 32 muffins.
Now we can find out how many are left:
5/8 of 32 = 20
So there are 20 muffins left.

Suppose C(t) is the cost, in thousands of dollars, of producing t tons of white paper. If
C'(10) = 380,
estimate the cost of producing an additional 500 lb of paper once 10 tons have been produced.
It is estimated that producing an additional 500 lb of paper once 10 tons have been produced would cost approximately $95,000.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To estimate the cost of producing an additional 500 lb of paper, we need to first convert 500 lb to tons.
1 lb = 0.0005 tons
So, 500 lb = 0.25 tons
Now, we can use the marginal cost formula:
MC = C'(t)
where MC is the marginal cost and C'(t) is the derivative of the cost function with respect to t.
We are given that C'(10) = 380, which means that the marginal cost of producing the 10th ton of paper is $380,000.
To estimate the cost of producing an additional 500 lb of paper once 10 tons have been produced, we need to find the marginal cost at t = 10.
Therefore, the estimated cost of producing an additional 500 lb of paper is:
MC(10) ≈ C'(10) ≈ $380,000 per ton
0.25 tons x $380,000 per ton = $95,000
Hence, it is estimated that producing an additional 500 lb of paper once 10 tons have been produced would cost approximately $95,000.

Explain why 200,000 square kilometers is a good estimate forthe area of South Dakota.
Answer:
Step-by-step explanation:
200,000 square kilometers is a good estimate for the area of South Dakota because the actual area of South Dakota is approximately 199,729 square kilometers according to the United States Geological Survey (USGS).
This means that the estimate is only off by about 0.1% of the actual area. This level of accuracy is generally considered to be very good for an estimate, especially when dealing with large areas like states or countries.
Additionally, 200,000 square kilometers is a round number and easy to remember, making it a useful estimate in contexts where a precise value is not necessary. It also allows for quick comparisons with other areas or states that may be roughly similar in size.
Overall, 200,000 square kilometers is a good estimate for the area of South Dakota because it is reasonably close to the actual value, easy to remember, and useful for rough comparisons with other areas.
ALSO:
South Dakota is approximately 383 miles long (east to west) and 237 miles wide (north to south).
It has the approximate shape of a rectangle, its Area = (Base x Height)= (383 x 237)= 90,771.00 miles ^2 which are 235,095.81 Km^2. So by this geometric reasoning we can have a correct approximation of the area of South Dakota.

Gene owns 1,200 shares of XYX Corporation. The company instated a 1 for 10 reverse stock split on November 7. The pre split market price per share was $1.20.
Answer:
After the reverse stock split, Gene will own 120 shares of XYX Corporation.
To calculate the post-split market price per share, we can start by finding the total value of Gene's shares before the split:
Total value before split = 1,200 shares * $1.20 per share = $1,440
Since the reverse stock split is 1 for 10, the total number of shares outstanding will be reduced by a factor of 10, and the price per share will be increased by a factor of 10:
Total value after split = 120 shares * $12.00 per share = $1,440
Therefore, the post-split market price per share is $12.00.

Describe Algebraic Expression?Algebraic expressions are used to represent mathematical relationships and formulas, and can be used to solve equations and manipulate equations in order to isolate variables or solve for unknown quantities. They are used extensively in algebra, calculus, and other branches of mathematics.
We are given that the time for one swing is given by the formula:
t = 2√(L/32.2)
where L is the length of the rope swing in feet, and 32.2 is the acceleration due to gravity in feet per second squared.
We are also given that one swing takes 3.5 seconds, so we can write:
3.5 = 2√(L/32.2)
Squaring both sides, we get:
12.25 = 4(L/32.2)
Multiplying both sides by 32.2/4, we get:
L = 32.2 × 12.25/4
L ≈ 98.9 feet

you find sneakers for $79.95. In the paper you see they will be on sale for 63.96 next week what is the percent discount that they will be offering?
The percent discount being offered is 20%.
What is percentage ?
Percentage is a way of expressing a number as a fraction of 100. It is often denoted by the symbol %, which means "per cent" or "out of 100". Percentages are used to compare two quantities and express the relationship between them in terms of the fraction of one quantity that the other quantity represents.
To find the percent discount, we need to first calculate the amount of discount that is being offered. We can do this by subtracting the sale price from the original price:
Discount = Original Price - Sale Price
Discount = $79.95 - $63.96
Discount = $15.99
Next, we can calculate the percentage discount by dividing the discount by the original price and then multiplying by 100:
Percent Discount = (Discount / Original Price) x 100
Percent Discount = ($15.99 / $79.95) x 100
Percent Discount = 20%
Therefore, the percent discount being offered is 20%.

g(x).
Answer:
The formula for the function g(x) obtained when the graph of f(x) = √x is shifted up 1 unit and to the left 6 units is g(x) = √(x + 6) + 1.
Step-by-step explanation:
To obtain the formula for the function g(x) when the graph of f(x) = √x is shifted up 1 unit and to the left 6 units, we can use the following transformations:
A vertical shift up by 1 unit is represented by adding 1 to the function: f(x) + 1
A horizontal shift to the left by 6 units is represented by replacing x with (x + 6): f(x + 6)
Therefore, the formula for the function g(x) is:
g(x) = f(x + 6) + 1
Substituting the expression for f(x), we get:
g(x) = √(x + 6) + 1
So, the formula for the function g(x) obtained when the graph of f(x) = √x is shifted up 1 unit and to the left 6 units is g(x) = √(x + 6) + 1.

what is 7x [6+10(1+1)]=4 x 5
Answer:
The solution to the equation 7x [6+10(1+1)] = 4 x 5 is x = 10/91.
Step-by-step explanation:
o solve the equation 7x [6+10(1+1)] = 4 x 5, we can use the order of operations, which tells us to first perform the operations inside the parentheses, then the multiplication and finally the multiplication by 7x.
So, we have:
7x [6+10(1+1)] = 4 x 5
7x [6+10(2)] = 20
7x [6+20] = 20
7x [26] = 20
182x = 20
To solve for x, we can divide both sides by 182:
182x/182 = 20/182
x = 20/182
Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, we get:
x = 10/91
Therefore, the solution to the equation 7x [6+10(1+1)] = 4 x 5 is x = 10/91.

The average annual interest rate r (in decimal form) of a savings account is
V₂
represented by the formula r =
1, where Vo is the initial investment
Vo
and V₂ is the balance of the account after 2 years. Find the average annual
interest rate r of a savings account with an initial investment of $400 and a
balance of $422 after 2 years.
The interest rate of the saving account is 2.71%
What is simple interest?Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.
Given, the interest rate of a savings account is represented by the formula such that:
r = [tex]\sqrt{\frac{V_2}{V_0} } - 1[/tex]
Where V₀ is the initial investment,
and V₂ is the balance of the account after 2 years.
In our case,
V₂ = 422
V₀ = 400
So the interest rate,
r = [tex]\sqrt{\frac{422}{400} } - 1[/tex]
r = 1.0271 - 1
r = 0.0271
therefore, the interest rate of the saving account is 2.71%
