A box shaped like a right rectangular prism
measures 5 centimeters by 3 centimeters by
2 centimeters. What is the length of the interior
diagonal of the prism to the nearest hundredth?
Answer:
[tex]\sqrt{38}[/tex]
Step-by-step explanation:
Given that:
The 3 demensions of the right rectangular prism measures 5 centimeters by 3 centimeters by 2 centimeters.
Because we do not know which one is the height, the length and the width of the box, so we assume them (it does not affect the length of the interior
diagonal )
the height : 5 centimetersthe length : 3 centimeters the width : 2 centimetersTo find the length of the interior diagonal of the prism, we use the following formula:
d = [tex]\sqrt{l^{2} +w^{2} +h^{2} }[/tex] = [tex]\sqrt{5^{2} +3^{2} + 2^{2} } = \sqrt{38}[/tex]

Does it seem fair to you that a hit could be a home run at one stadium but not at others?Explain.
Answer:
No. If standards differ at different sports stadiums, that makes the game unfair for one team or the other. A win at one stadium could be a loss at another. To make the game fair, all facilities should be equal.
Step-by-step explanation:
The unique dimensions and characteristics of each baseball stadium, known as park factors, can impact whether a hit becomes a home run. Although it might seem unfair, it's the same for all teams and is part of the game's complexity. Not only the player's skill but also their knowledge of the park's attributes can influence the outcome of the game.
Explanation:The different sizes and features of baseball stadiums, known as park factors, can impact game dynamics, including whether a hit results in a home run. This is part of the sport's complexity and challenge, as players must adapt their strategies for different venues. It might seem unfair, but it's the same for all teams as they each host and visit various stadiums throughout the season.
In some parks, for example, the distance from home plate to the outfield wall is less, which could make it easier for a hit to become a home run. In contrast, larger parks or those at higher altitudes, where the air is thinner and ball travels further, might be tougher to score a home run.
All these make baseball a fascinating sport, where not only the player's skill but also nuanced aspects like knowledge of the park play an essential role in the outcome of the game. Thus, by definition, a home run is still a successful hit, but where that hit ends up can depend on numerous variables, including the park's attributes.

The case of 12 bottles of shampoo holds a total of 126 ounces. If each bottle of shampoo contains the same amount, which represents the total volume of shampoo in ounces, y, of any number of bottles, x?
Each bottle of shampoo contains 10.5 ounces. The formula for the total volume of shampoo (y) in terms of the number of bottles (x) is y = 10.5x.
Let's denote the amount of shampoo in each bottle as b (in ounces). Since there are 12 bottles of shampoo, the total volume of shampoo in ounces (y) is given by the product of the number of bottles (x) and the amount in each bottle (b). So, the equation is:
y = x * b
The problem states that the case of 12 bottles holds a total of 126 ounces. This can be expressed as:
126 = 12 * b
Now, we can solve for b by dividing both sides of the equation by 12:
b = 126 / 12
Simplifying:
b = 10.5
So, each bottle of shampoo contains 10.5 ounces.
Therefore, the formula for the total volume of shampoo (y) in terms of the number of bottles (x) is:
y = 10.5x

Amelia runs a catering business. Based on her records, her
weekly profit can be approximated by P = 2x2 - 44x – 150,
where x is the number of meals she caters and P is her profit.
When P is negative, Amelia has lost money.
1) What is the least number of meals Amelia needs to cater
in order to begin making a profit?
2) If she caters no meals one week, how much money does
she lose?
3) What is her profit for catering 50 meals?
Answer: (1) The least number of meals is 26 (2) She loses 150 if she caters no meal in one week. (3) Her profit would be 2,650 if she caters for 50 meals in one week
Step-by-step explanation: The weekly profit is given as a quadratic equation which is;
P = 2x² -44x - 150
We begin by solving for the value of x.
When 2x² -44x - 150 = 0
Divide all through by 2
x² - 22x - 150 = 0
By factorization,
(x - 25) (x + 3) = 0
(x -25) = 0 OR (x + 3) = 0
When x - 25 = 0
x = 25
When x + 3 = 0
x = -3
What this implies is that when Amelia caters for 25 meals in a week, her profit is calculated as follows
P = 2x² - 44x -150
P = 2(25)² - 44(25) - 150
P = 2(625) - 1100 - 150
P = 1250 - 1100 - 150
P = 0
(1) Therefore she must cater for at least 26 meals before she can begin to make any profit.
(2) She loses 150 if she caters no meal in one week.
This can be calculated as follows;
When x = 0,
P = 2x² - 44x - 150
P = 2(0)² - 44(0) - 150
P = 0 - 0 -150
P = -150
(3) When she caters 50 meals her profit becomes 2,650
P = 2x² - 44x - 150
P = 2(50)² - 44(50) - 150
P = 2(2500) - 2200 - 150
P = 5000 - 2200 - 150
P = 2650
1) The least number of meals Amelia needs to cater in order to begin making a profit is 25.
2) Amelia loses $150 if she caters no meals in a week.
3) For catering 50 meals, Amelia's profit is $2650.
Explanation:1) To find the least number of meals Amelia needs to cater in order to begin making a profit, we need to determine when her profit, P, becomes positive. In other words, we need to solve the quadratic equation 2x^2 - 44x - 150 = 0 for x. This equation can be factored as (2x + 6)(x - 25) = 0. Therefore, x = -3 or x = 25. Since the number of meals cannot be negative, the least number of meals Amelia needs to cater in order to begin making a profit is 25.
2) If Amelia caters no meals one week, the profit, P, is given by P = 2(0)^2 - 44(0) - 150. Simplifying this equation, we get P = -150. Therefore, Amelia loses $150 if she caters no meals in a week.
3) To find Amelia's profit for catering 50 meals, we substitute x = 50 into the profit equation P = 2x^2 - 44x - 150. Plugging in x = 50, we get P = 2(50)^2 - 44(50) - 150 = 5000 - 2200 - 150 = $2650.

The equation shows a number multiplied by 5. n x 5=? Which of these is true about the results?
Answer:
5n
Step-by-step explanation:
The result of n x 5 is equal to 5 times the value of n.
The equation 'n x 5' represents the product of a number n and 5. The result can be positive or negative based on the value and sign of n. Also, parenthesis placement in expressions greatly affects the outcome due to the order of operations.
Understanding the Multiplication of Numbers and Order of Operations
The equation n x 5 indicates that a number n is being multiplied by 5. The results of this product will depend on the value of n and whether n is positive, negative, or zero. For example, if n is positive, like 2, then the product is also positive: 2 x 5 = 10. If n is negative, like -3, the result is negative: (-3) x 5 = -15. It's important to remember that when two positive numbers multiply, the answer has a positive sign, and when two negative numbers multiply, the result is also positive. However, if the two numbers have opposite signs, the answer will have a negative sign.
Furthermore, the placement of parentheses can affect the result of mathematical expressions. For instance, 2 + (3 x 5) is not the same as (2 + 3) x 5 due to the order of operations. In the first expression, multiplication is performed first, resulting in 17, whereas the second expression results in 25.
Understanding the rules of multiplication, including the signs of the numbers involved and the order of operations, is essential for solving equations and expressions correctly.
What is the area in square millimeters of the triangle outlined
on the origami figure?
HELPPPPP
The area in square millimeters of the triangle outlined on the origami figure is 441 square millimeters.
In Mathematics and Geometry, the area of a triangle can be calculated by using the following mathematical equation (formula):
Area of triangle = 1/2 × b × h
Where:
b represent the base area.h represent the height.Conversion:
7 cm to mm = 7 × 10
7 cm to mm = 70 mm.
1.26 cm to mm = 1.26 × 10
1.26 cm to mm = 12.6
By substituting the given side lengths into the formula for the area of a triangle, we have the following;
Area of triangle = 1/2 × b × h
Area of triangle = 1/2 × 70 × 12.6
Area of triangle = 35 × 12.6

pumpkin to reach its maximum height? What is the pumpkin's
maximum height? Round to the nearest hundredth, if necessary.
Answer:
Time taken to reach maximum height=4.69 seconds
Maximum Height=371.56feet
Step-by-step explanation:
Given the height function of the pumpkin:
[Tex]h = -16t^2 + 150t + 20[/tex]
The pumpkin reaches it's maximum height at its axis of symmetry.
Therefore, we determine its equation of symmetry.
The equation of symmetry:
[Tex]t=-\frac{b}{2a}[/tex]
a=-16, b=150.
Therefore:
[Tex]t=-\frac{150}{2*-16}=4.6875[/tex]
The pumpkin reaches maximum height after 4.6875 seconds.
At t=4.6875
[Tex]h = -16(4.6875)^2 + 150(4.6875)+ 20\\=371.5625\approx 371.56 \:feet[/tex]
The pumpkin's maximum height is 371.56 feet.
How are (3x)^2 and 3x^2 different?
