What can you say about the relationship between the volume of a rectangular prism and a pyramid?
When a prism and pyramid have the same base and height, their volumes are inversely proportional: the volume of the pyramid is one-third that of the prism.
A pyramid is a three-dimensional object that has faces made of triangles and a base made of polygons. The base is the bottom, while the faces are the sides.
A prism is a three-dimensional object having two identically shaped and sized polygonal bases and rectangular sides. In the actual world, a cardboard box serves as an illustration of a prism.
When a pyramid and a prism have bases and heights that are equivalent, the pyramid can fit inside the prism.
In reality, when this is the case, the pyramid occupies precisely one-third of the prism's volume. When a prism and pyramid have the same base and height, their volumes are inversely proportional: the volume of the pyramid is one-third that of the prism.

determine the average rate of change in concentration of b from t=0 s to t=212 s.
The average rate of change in concentration of b from t= 0 s to t = 212 s as calculated from the data given above is 0.004811 m/s.
The average rate of change is given by the formula ,
concentration change / time change.
First we will calculate the rate of change for A
rate change = 0.140 - 0.650 = -0.510 M
time difference = 212 s − 0 s = 212 s
Rate of concentration change = -0.510 M / 212 s = -0.002405 M/s
The - sign indicates that the [A] is decreasing with time.
In order to calculate the concentration rate of B we will write it in the form of stoichiometry
B = 2 x 0.002405 = +0.004811 m /s

Is negative and positive infinity the same?
No, negative infinity and positive infinity are not the same. Negative infinity is a amount of number that is less than any other number, while positive infinity is a number that is greater than any other number.
Negative infinity is a number that is less than any other number. It is represented by a negative sign followed by an infinity symbol, and it is usually written as "-∞". Negative infinity is the opposite of positive infinity, which is a number that is greater than any other number. Positive infinity is usually written as "+∞". Negative infinity is used in mathematics to signify the smallest possible number or the lower limit of a range, while positive infinity is used to signify the largest possible number or the upper limit of a range. The two numbers are not the same, as they represent opposite extremes of a range. Negative infinity is the lowest possible number and positive infinity is the highest possible number.

Find 375g as a percentage of 15kg.
Answer:
[tex] \sf \: 375g \: is \: 2.5\% \: of \: 15kg[/tex]
Step-by-step explanation:
Conversion of 15 kg into grams,
→ 1 kg = 1000 g
→ 15 kg = 15000 g
Let's find the percentage,
→ (375g ÷ 15kg) × 100
→ (375/15000) × 100
→ 0.025 × 100
→ 2.5%
Hence, the answer is 2.5%.

In quadrilateral pqrs, the coordinates are p(0, 0), q(a + c, 0), r(2a + c, b), and s(a, b). How can you use coordinate geometry to show that the diagonals are perpendicular?.
Find the slopes and their product should be - 1 for the diagonals to be perpendicular.
The points p and q have zero y-coordinate, so they are on the y-axis.
The points r and s have same y-coordinate b, so they are on the parallel line to the y-axis.
The points p and r are opposite to each-other, similarly points s and q are opposite points. So the diagonals are pr and qs. This is also known from the order of vertices in the name of the quadrilateral.
Slopes are:
m(pr) = (b - 0)/(2a + c - 0) = b / (2a + c)m(qs) = (b - 0) / (a - a - c) = - b/cThe product of slopes:
b / (2a + c) × ( - b / c) = - b² / (2ac + c²)The diagonals are perpendicular if:

How to solve time and work problems?Knowing the formulas can immediately lead you to a solution upon reading the question. Therefore, knowing the formula for any topic in numerical ability simplifies the solution and associated calculations.
Here are a few of these essential time and work formulas for your reference.
Work Performed = Time Required Rate of Work
Work Rate = 1 / Time Taken
Duration = 1 / Rate of Work
If a piece of work is completed in x number of days, then the amount of work completed in one day is equal to 1/x. Total Work Completed = Number of Days Efficiency.
Time and Productivity are inversely proportional to one another X:
if y is the ratio of the number of men needed to complete a piece of work, then y:x is the ratio of the time required by those men to complete the work.
If x number of people can complete W1 work in D1 days while working T1 hours per day, and y number of people can complete W2 work in D2 days while working T2 hours per day, then the relationship between them is Time and Work Formula i..e;
[tex]\frac{M1.D1.T1}{W1} =\frac{M2.D2.T2}{W2}[/tex]
Calculation:Monica can do the work in 9 hours so she does a work of 1/9 in an hour.
The same work done by Monica and James takes 6 hours so they both can do a 1/6 th of work in an hour.
Developing the relation:
[tex]\frac{1}{9}+\frac{1}{x}=\frac{1}{6}[/tex]
here, the speed of Monica is 1/9 and the speed of James in completing the work is 1/x and the speed of them both is 1/6

What is subtraction and division Properties of Inequality?The subtraction property of inequality is applied when an inequality holds the addition operator previously, i.e
x + a < b => x + a - a < b - a
=> x< b - a.
The division property of inequality is mainly applied to the shift coefficient of the variable to another side of the inequality, i.e
2x< b => 2x/2<b/2
⇒ x< b/2.
We have, ryan is going to rent a truck for one day. There are two companies say company A and company B, in which ryan have to choose one for rent a truck for one day.
Let , Total cost charged by company A = $a
Total cost charged by company B = b
The number of miles driven = m miles
For Company A, initail fee = $40 and
Additional charge = .80 cents/mile driven
so, a = 40 + 0.8m --(1)
For Company B, initail fee = $53 and
Additional charge = .60 cents/mile driven
so, b = 53 + 0.6m --(2)
We want to know the mileage at which company A charges less than B i.e a < b
Now, using equation (1) and (2) ,
40 + 0.8m < 53 + 0.6m
Simplify the above Inequality,
=> 40 + 0.8 m - 40 < 53 - 40 + 0.6 m
=> 0.8 m < 13 + 0.6 m
=> 0.8 m - 0.6 m < 13 + 0.6 m - 0.6 m
=> 0.2 m < 13
=> m < 13/0.2

What is the value of k for which the roots of the equation 3x 2 )+ KX 3 0 are equal?
The equation 3x2 + Kx - 30 has equal roots when the discriminant (D) of the equation is equal to zero.
The discriminant of a quadratic equation is given by the formula D = b2 - 4ac, where a = 3, b = K, and c = -30.
Substituting these values into the formula, we get:
D = K2 - 4(3)(-30)
D = K2 + 360
Therefore, K2 = -360, and K = √(-360) = 6√(-5)

Answer: I think it's 13
Step-by-step explanation: So we need to fill in the distance formula. It's d=√((x_2-x_1)²+(y_2-y_1)²).
-6=x_1
-3=y_1
6=x_2
2=y_2
Now you plug in your coordinates to the formula, so you get d=√((6--6)²+(2--3²)
(6-(-6)²=144
(2-(-3²)=-7
So now 144+25=169
The square root of 169 is 13, so d=13. That should be your answer! Let me know if it's right

The ratio of the error is; 0.3333
The Percent error of the given problem is; 33.33%
How to find the percentage error?We are given;
Amount spent by John on shopping = $75
Amount expected to spend = $100
Since this is what was given then it means we will have the following;
The approximate value to be spent = 100 dollars
Exact Value spent = 75 dollars
Therefore, the error made is;
Error = Approximate value - Exact value
Error = 100 - 75
Error = 25 dollars
Thus, the error when it is absolute is;
Absolute Error = ±25 dollars
Now, the ratio will be;
Ratio(e) = Error/exact value spent
e = 25/75 = 0.3333
Percent Error = error * 100%
Percent error = 0.3333 * 100%

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Let x represent the number of child tickets that were sold
Let y represent the number of adult tickets that were sold

The number of adult tickets sold was three times greater than the number of child tickets,
y= 3x
Substitute 3x for y in the equation,
5.40x + 9.40y= 974.40
5.40x + 9.40(3x)= 974.40
