The formula for the volume of a cone is ⅓ r2h cubic units, where r is the radius of the circular base and h is the height of the cone.The volume of any sphere is 2/3rd of the volume of any cylinder with equivalent radius and height equal to the diameter.The formula for the volume of a sphere is 4⁄3πr³. For a cylinder, the formula is πr²h. A cone is ⅓ the volume of a cylinder, or 1⁄3πr²h

Step-by-step explanation:

The formula for volume is: Volume = length x width x height

Answer:

Step-by-step explanation:

Volume of a sphere:  4/3 π r³

4/3 (3.14) (2.5)³ =

4/3 (3.14) (15.625) = 65.42 units³

Volume of a cylinder = π r² h

(3.14) (2.5)² (4)

(3.14) (6.25)(4) = 78.5 units²

Volume of a Cone = 1/3 π r² h

(1/3)(3.14)(2.5)²(4) =

(1/3)(3.14)(6.25)(4) = 26.17 units²

To get the inverse of a conditional, the hypothesis and the conclusion are negated, without interchanging them.

So, we have:

Inverse of a conditional ⇒ A new statement formed by negating both the hypothesis and the conclusion.

To get the contrapositive of a conditional, the hypothesis and the conclusion are negated, after interchanging them.

So, we have:

Contrapositive of a conditional ⇒ Formed by exchanging the hypothesis and the conclusion and negating both of them.

To get the converse of a conditional, we simply interchange the hypothesis and the conclusion, without negating them

So, we have:

Converse of a conditional ⇒ A statement formed by interchanging the hypothesis and the conclusion in a conditional statement.

Determine the most precise name for KLMN (parallelogram, rhombus, rectangle, or square). Explain how you determined your answer. You must support your answer using length or slope.

Answer:

The precise name for KLMN is either a square or a rhombus

Step-by-step explanation:

To find the length of the sides, when you have vertices (x₁, x₂)and (y₁, y₂) we use the formula

√(x₂-x₁)²-(y₂-y₁)²

K(-5, -1), L(-2, 4), M(3, 1), N(-2, 4)

Side/ Length KL = K(-5, -1), L(-2, 4)

= √(x₂-x₁)²-(y₂-y₁)²

= √(-2 -(- 5))² + (4 - (-1))²

= √3² + 5²

= √9 + 25

= √34

Side/ Length LM = L(-2, 4), M(3, 1),

= √(x₂-x₁)²-(y₂-y₁)²

= √(3 - (-2))² + ( 1 - 4)²

= √5² + -3²

= √25 + 9

= √34

Side/ Length MN = M(3, 1), N(-2, 4)

√(x₂-x₁)²-(y₂-y₁)²

= √(-2 - 3)² + (4 - 1)²

= √-5² + 3²

= √25 + 9

= √34

Side/ Length KN = K(-5, -1), N(-2, 4)

√(x₂-x₁)²-(y₂-y₁)²

= √(- 2 -(- 5)² + (4 - (-1))²

= √3² + 5²

= √9 + 25

= √34

From the above calculation, we can see that

KL = √34

LM = √34

MN = √34

KN = √34

This means Length KL = LM = MN = KN

This shape is a Square and a Rhombus. This reason is a square and a rhombus are Quadrilateral shapes whose sides are equal to each other.

As far as we are aware, a straight angle is defined as 180 degrees then the bi-conditional assertion is true.

It combines the conditions "if two line segments are congruent then they are of equal length" and "if two line segments are of equal length then they are congruent." Only when both conditionals are true does a biconditional hold. The symbol "or" is used to denote bi-conditionals.

A statement with two conditions is one that has the form "p if and only if q." In other words, if p, then q and if q, then p. "P iff q" or "p q" are other ways to express the biconditional "p if and only if q."

Since we have given that

1)  If and only if the angle's measurement is 90 degrees, it is a right angle : True.

As is common knowledge, one angle in a right-angled triangle must be 90 degrees.

2) If and only if an angle is obtuse, it measures 120 degrees : True

Obtuse angle is a term used to describe angles that are more than 90° but less than 180°.

And 90°<120°<180°

3) Only if the angle is a straight angle does it measure 180 degrees : True

As far as we are aware, a straight angle is defined as 180 degrees.

As a result, every bi-conditional assertion is true.

Answer:

Three sheets will be left over.

Step-by-step explanation:

Well, if you have 80 sheets of paper, and seven students need it, you would first divide the 80 sheets to the seven students using the equation 80 ÷ 7 = 11.4. You won't be giving fractions of paper to the students so you would round to 11. If each of the seven students gets 11 sheets of paper, 77 sheets will have been used. 80 - 77 = 3. So, there will be three sheets left over.

Answer:

48. 192

Step-by-step explanation:

In order to get from 3/4 to 3/16, one way would be to divide by 4. Another way is to multiply 3/4 by 1/4.

You can test whether multiplying by 4 works by multiplying 3/4 by 4 and 3 by 4.

When 3/4 is multiplied by 4, it would equal 12/3 which will simplify to 3. This can be done again with 3*4=12.

So the answer would be 12*4 = 48 and 48*4 = 192.

About 68% percent of light bulbs can last within one standard deviation of the mean, between 57.6 hours and 66.4 hours.

To determine the percentage of light bulbs that can last within one standard deviation of the mean, between 57.6 hours and 66.4 hours, you can follow these steps:

1. Identify the range of values:

In this case, the range is between 57.6 hours and 66.4 hours.

2. Recognize that this range represents one standard deviation from the mean.

In a normal distribution, approximately 68% of values fall within one standard deviation of the mean.

So, about 68% of light bulbs can last within one standard deviation of the mean, between 57.6 hours and 66.4 hours.

The difference quotient of f(x) = -5x² + 7x + 3 is equal to -5h - 10x + 7.

In Mathematics, the difference quotient of a given function can be calculated by using the following mathematical equation (formula);

\(Difference\; quotient = \frac{f(x+h)-f(x)}{(x+h)-h}=\frac{f(x+h)-f(x)}{h}\)

Based on the given function, we can logically deduce the following parameters that forms the components of the difference quotient;

f(x) = -5x² + 7x + 3

f(x + h) = -5(x + h)² + 7(x + h) + 3

f(x + h) = -5(h² + 2hx + x²) + 7x + 7h + 3

f(x + h) = -5h² - 10hx - 5x² + 7x + 7h + 3

By substituting the above parameters into the numerator of the difference quotient formula, we have the following:

f(x + h) - f(x) = -5h² - 10hx - 5x² + 7x + 7h + 3 - (-5x² + 7x + 3)

f(x + h) - f(x) = -5h² - 10hx - 5x² + 7x + 7h + 3 + 5x² - 7x - 3

f(x + h) - f(x) = -5h² - 10hx + 7h

By factorizing the function, we have;

f(x + h) - f(x) = -h(5h + 10x - 7)

\(Difference\; quotient = \frac{-h(5h + 10x - 7)}{h}\)

Difference quotient = -5h - 10x + 7

The relative frequency for students who scored a C is 0.47 (rounded to two decimal places).

Relative frequency is defined as the ratio of the number of times an event occurs in a given data set to the total number of trials in the data set.

It is represented as a fraction, decimal, or percentage. It assists in the evaluation of probability in statistics.

To solve this question, we need to add the scores of students who scored a C and divide it by the total number of students.

Given that 14 students scored an A, 30 students scored a B, 92 students scored a C, 38 students scored a D, and 26 students scored an F.

The total number of students who took the exam is:14 + 30 + 92 + 38 + 26 = 200

Thus, the relative frequency of students who scored a C is:92 / 200 = 0.46 (rounded to two decimal places) or 46% (percentage form).

George's friend Clarence, who is concerned about consumers, suggests implementing a price ceiling that is 50% lower than the monopoly price. With this price ceiling in place, the quantity demanded would increase to 65 units. However, the exact quantity supplied at this new price is not provided in your question.

George's friend Clarence is suggesting a price ceiling, which is a government-imposed limit on how high a price can be charged for a good or service. In this case, the price ceiling is set at 50% below the monopoly price. This means that the price charged for the good or service would be significantly lower than what the monopolistic supplier would typically charge.

At this lower price point, Clarence predicts that the quantity demanded would increase to 65 units, indicating that consumers would be more willing to purchase the product due to its lower price. However, it is unclear what the quantity supplied would be at this price point, as that information is missing from the question.
