Since it's 45% OF 210.5 ft we know it will be multiplication because of means to multiply.
[tex]210.5 \times 0.45[/tex]
It would look like this becuase a percentage is a decimal answer. we'd find that by moving the decimal place two places to the left.
94.725 would be the result if 45% of 210.5
We will still to to subtract but first let me show you how to do it with ratios.
To do this we set it up like so.
[tex] \frac{45}{100} = \frac{?}{210.5} [/tex]
We know that the percentage 45 is out of 100 percent. we also know that 210.5 is the whole number we are trying to find the fraction of. Therefore 210.5 would be equivalent to the 100 because 210.5 is the entire number (210.5/210.5).
First we divide 210.5 by 100 to figure out how much to multiply the numerator by to find the number (or numerator) over 210.5.
We come up with the number 2.105
We then multiply that number by 45 to find the numerator of the fraction of 210.5
45 × 2.105 = 94.725
Now to find the remainder of fencing left we subtract 94.725 from 210.5 since we only found out what 45% of 210.5 is not how much is left over.
We come up with an answer of 115.775 ft which we round to 115.78 ft of fencing.

In each of the equations or inequalities below, find all the integer values of x that make the equation or the pair of inequalities true. Explain reasoning for each part.
Part A: |x|=17
Value Of X:
Part B: |x+9|=15
Value Of X:
Part C: |x-10| ≤ 13 and |x-10| ≥ 9
(Find the values of x that make both inequalities true)
Values of X:
Answers
Part A: if the absolute value of X was 17, then X could equal -17 or 17.
Part B: |x+9|=15. We know that 6+9=15, so X could equal -6 or 6.
Part C: |x-10| ≤ 13. We know that 23-10 is 13. So 23 would be the greatest value of X. Then, for the smallest value of X, if we insert -3 in the equation to take the place of the variable, we get |-3-10|=13. So -3 would be the smallest value of the equation. X≤ 23 and X≥-3.
In a six-sided dice game, a prize is won if the arithmetic mean of number rolled is 3.25-3.75. In a second game, a prize is won if the arithmetic mean is more than 4.5. In which game would you rather roll the dice 20 times or 200 times
Answers
For rolling the dice 200 times, the same logic applies. Regardless of the number of rolls, the game with the higher probability of winning, which is the second game, is preferred.
To determine which game is more favorable for rolling the dice, we need to calculate the expected value for each game. The expected value represents the average outcome of rolling the dice.
For the first game, the possible outcomes are integers between 1 and 6. The arithmetic mean should be between 3.25 and 3.75 to win a prize. So, we need to find the probability of rolling numbers that satisfy this condition.
Let's denote [tex]\( p_1 \)[/tex] as the probability of winning the first game. To find [tex]\( p_1 \)[/tex], we calculate the probability of rolling numbers between 13 and 18 (inclusive) since the sum of these numbers falls within the range of 3.25 to 3.75.
[tex]\[ p_1 = \frac{6}{6^2} = \frac{1}{6} \][/tex]
For the second game, we need the arithmetic mean to be more than 4.5. This means the sum of the numbers should be more than [tex]\( 4.5 \times 6 = 27 \)[/tex]. Since the maximum sum of rolling six dice is 36, all outcomes satisfy this condition.
Let's denote [tex]\( p_2 \)[/tex] as the probability of winning the second game. Since all outcomes are favorable, [tex]\( p_2 = 1 \)[/tex].
Now, we calculate the expected values for each game:
[tex]\[ E_1 = p_1 \times \text{Prize amount for game 1} \][/tex]
[tex]\[ E_2 = p_2 \times \text{Prize amount for game 2} \][/tex]
Given that the prize amount is the same for both games, we can compare the expected values directly.
For rolling the dice 20 times:
[tex]\[ E_1 = \frac{1}{6} \times \text{Prize amount} \][/tex]
[tex]\[ E_2 = 1 \times \text{Prize amount} \][/tex]
Since [tex]\( \frac{1}{6} \)[/tex] is less than 1, it's better to choose the game with the higher probability, which is the second game.
For rolling the dice 200 times, the same logic applies. Regardless of the number of rolls, the game with the higher probability of winning, which is the second game, is preferred.
The complete question is:
In a six-sided dice game, a prize is won if the arithmetic mean of number rolled is 3.25-3.75. In a second game, a prize is won if the arithmetic mean is more than 4.5. In which game would you rather roll the dice 20 times or 200 times
A figure is made up of 5 identical squares, the area of the figure is 405 squares inches, what is the perimeter
Answers
# # #
# # . . . . . . . . will have a perimeter of 90 inches
# # # # # . . . will have a perimeter of 108 inches⊕
To find the perimeter of a figure made up of 5 identical squares with a total area of 405 square inches, you would calculate the side length of one square as 9 inches and then consider the shared sides. The perimeter would be 180 inches.
The question describes a figure made up of 5 identical squares with a total area of 405 square inches. To find the area of one square, we divide the total area by the number of squares, resulting in 405 ÷ 5 = 81 square inches per square. Knowing that the area of a square is given by the formula A = side length × side length (or A = a²), we can determine that each side of the square is
The square root of 81, which is 9 inches. Since there are 5 squares, the figure will have overlapping sides when the squares are combined. To calculate the perimeter, we need to consider that each square shares a side with another, except for the starting and ending squares in the arrangement. Therefore, the perimeter of the entire figure will be 9 inches times 4 for the first or outer square, plus 9 inches times 3 for each of the remaining squares (as one side is shared). This gives us a total perimeter of 4 × 9 + (4 × 9 × (5-1)) inches.
When calculating the perimeter of the entire figure, the formula for the perimeter is P = 4×side + 4×(number of squares - 1) × side, resulting in a final computation of P = 4×9 + 4×4 × 9, which equals 180 inches.

Since the end time is 10:30 and the activity was started 3/4 an hour earlier, we need to subtract 3/4 an hour from 10:30 to get the starting time.
3/4 hour = 45 min
10:30 - 45 min = 9:45
So, the starting time is 9:45.
Hope this helps!
1 hour=60 minutes
3/4 hour=45 minutes
Then, we subtract 45 minutes from 10:30 to get the starting time:
10:30-45 minutes

The change in the scale factor from the old scale to the new scale is option A; 3 to 1.
What is Scale?The ratio used to depict the relationship between the dimensions of a model or scaled figure and the corresponding dimensions of the real figure or object is called the scale. On the other hand, a scale factor is a value that is used to multiply all of an object's parts in order to produce an expanded or decreased figure.
Given, A scale drawing of a house addition shows a scale factor of 1 in. = 3.3 ft.
Since Josh decides to make the house addition smaller,
he changes the scale of the drawing to 1 in. = 1.1 ft.

What are two different ways of factoring –3x – 9? Select all that apply. A. –3(x + 3) B. 3(x + 3) C. 3(–x – 3) D. –3(x – 3)
Answers
Answer:
A and C
Step-by-step explanation:
Two different ways of factoring -3x - 9 are:
A. -3(x + 3)
C. 3(-x - 3)
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.
To factor -3x - 9, we can rewrite it as -3(x + 3) or 3(-x - 3).
Both of these expressions are in the form of a product of a constant and a binomial (a polynomial with two terms).
Option A, -3(x + 3), can be obtained by applying the distributive property, which states that we can multiply a constant by each term in a binomial to obtain the product.
In this case, we have -3 × x + -3 × 3 = -3x - 9.
Option C, 3(-x - 3), can also be obtained using the distributive property. In this case, we have 3 × -x + 3 ×-3 = -3x - 9.
Option B, 3(x + 3), is incorrect because the coefficient of the x term is positive, whereas in the original expression it is negative.
Option D, -3(x - 3), is also incorrect because the coefficient of the x term is negative, whereas in the original expression it is positive.
