Bo would drive 893 miles on 38 gallons of fuel.The number of miles driven by Bo is directly proportional to the number of gallons of fuel he has used.

This means that if we know how many miles Bo has driven for a certain number of gallons of fuel, we can calculate how many miles he would drive with a different number of gallons of fuel. To calculate this, we need to first determine the ratio of miles driven per gallon of fuel used. To do this, we can use the data given in the problem: Bo has driven 188 miles on 8 gallons of fuel, and 799 miles on 34 gallons of fuel.

We can calculate the ratio of miles driven per gallon of fuel used by dividing the number of miles driven by the number of gallons used. In this case, the ratio is 188/8 = 23.5 miles per gallon. We can then use this ratio to calculate the number of miles Bo would drive on 38 gallons of fuel. To do this, we simply multiply the ratio by the number of gallons used, which in this case is 38. This gives us 38 x 23.5 = 893 miles.

Therefore, Bo would drive 893 miles on 38 gallons of fuel.

The total area is 36 cm squared.

a. q-p = 11-3 = 8, which is an even number. b. p+q = 3+11 = 14, which is an even number.

In mathematics, a prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other words, a prime number is a number that can only be divided evenly by 1 and itself.

There are various methods for finding prime numbers, such as the Sieve of Eratosthenes, which is a simple algorithm for generating all prime numbers up to a given limit. However, as the numbers get larger, it becomes increasingly difficult to find prime numbers, and there is no known formula for generating all prime numbers.

a. One possible example is:

p = 3

q = 11

Here, q-p = 11-3 = 8, which is an even number. However, if we add 1 to it, we get 9, which is odd but not prime (since it is divisible by 3).

b. One possible example is:

p = 3

q = 11

Here, p+q = 3+11 = 14, which is an even number. However, if we add 1 to it, we get 15, which is odd but not prime (since it is divisible by 3 and 5).

The statement "two proofs are required to establish the provable equivalence of two sentences of tfl" is false.

Only one proof is required to establish the provable equivalence of two sentences of TFL.

What is TFL? TFL (Truth-Functional Logic) is a form of propositional logic in which the only logical expressions are truth functions. Truth functions are built from a fixed set of truth-functional connectives or operators, each of which operates on one or more sentences to create a compound sentence. TFL's operators are all truth-functional; that is, the truth or falsity of a sentence depends solely on the truth or falsity of its atomic components and how they are combined by the operators.

Here are the five standard truth-functional operators in TFL:

Conjunction: AND (•)

Disjunction: OR (+)

Negation: NOT (~)

Conditional: IF...THEN (→)

Biconditional: IF AND ONLY IF (↔)

Proofs are used to demonstrate the validity of sentences in TFL. It is important to note that a sentence's validity is a property of the sentence itself, not the sentence's meaning. To demonstrate the validity of a sentence in TFL, proofs are created.In TFL, two sentences are provably equivalent if and only if they are logically equivalent. The provable equivalence of two sentences in TFL only requires one proof. Thus, the statement, "Two proofs are required to establish the provable equivalence of two sentences of TFL," is false.

To solve the quadratic function -3x² + 5x + 9 = 0, the formula that should be used is Option C: x = (-5 ± √133) / -6.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The quadratic formula is used to solve quadratic equations in the form of ax² + bx + c = 0, where a, b, and c are constants.

To use the quadratic formula to solve the equation -3x² + 5x + 9 = 0, we need to identify the values of a, b, and c.

In this case, a = -3, b = 5, and c = 9.

Therefore, we can use these values to plug into the quadratic formula -

x = (-b ± √(b² - 4ac)) / 2a

So the answer that can be used to find the solutions to the equation using the quadratic formula is -

x = (-5 ± √(5² - 4 × (-3) × 9)) / 2 × (-3)

Solving this equation we get -

x = (-5 ± √(25 + 108)) / -6

x = (-5 ± √133) / -6

Therefore, the solution is obtained by the equation x = (-5 ± √133) / -6.

Answer:

x = 5 , ML = 18

Step-by-step explanation:

the midsegment NP of the trapezoid is half the sum of the bases, that is

NP = [tex]\frac{JK+ML}{2}[/tex]

25 = [tex]\frac{4x-2+6x+2}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

50 = 10x ( divide both sides by 10 )

5 = x

Then

ML = 4x - 2 = 4(5) - 2 = 20 - 2 = 18

Answer:

To find the area of the isosceles trapezoid, we can use the formula:

Area = ((upper base + lower base) / 2) x height

First, we need to find the height of the trapezoid. We can use the Pythagorean theorem to find the height, since the legs of the trapezoid form a right triangle with the height as the hypotenuse.

Using the Pythagorean theorem:

height^2 = leg^2 - ((lower base - upper base) / 2)^2

= 5^2 - ((16 - 8) / 2)^2

= 25 - 4^2

= 9

height = 3 cm

Now that we have the height, we can use the area formula:

Area = ((8 + 16) / 2) x 3

= 12 x 3

= 36 cm^2

Therefore, the area of the isosceles trapezoid is 36 square centimeters.

The volume of the cylinder is 6π (18.84) cubic inches.

What is volume in mensuration ?

In mensuration, volume is the measure of the amount of space occupied by a three-dimensional object or a region in space. It is a measure of the capacity of an object and is usually expressed in cubic units, such as cubic meters, cubic centimeters, or cubic inches.

To understand the concept of volume in more detail, we can visualize the cylinder as a three-dimensional object with circular bases and curved sides. The height of the cylinder represents the distance between the circular bases, and the radius represents the distance from the center of the circular bases to their edges. The volume of the cylinder represents the amount of space inside the cylinder, and can be thought of as the product of the area of the circular base and the height of the cylinder.

To find the volume of a cylinder, we use the formula:

V = πr²h

where V is the volume, r is the radius, and h is the height of the cylinder. Since the diameter of the cylinder is given as 2 inches, we can find the radius as:

radius = diameter / 2 = 2 / 2 = 1 inch

Now, we can substitute the values of the radius and height into the formula to find the volume:

V = π(1)²(6) = 6π

Therefore, the volume of the cylinder is 6π cubic inches.

In practical applications, the concept of volume is used in many areas, such as manufacturing, engineering, architecture, and physics. For example, the volume of a cylinder can be used to calculate the amount of liquid it can hold, the amount of material needed to fill it, or the amount of air it can displace.
