In answering the question above, the solution is If a/b = 1/4 and c/d = 1/3, fraction then ad + bc = (1/4)(bd/4) + (1/3)(bd/3) = bd/16 + bd/9, which doesn't work.

A whole can be represented by any number of equal parts, or fractions. The number of units of a particular size is expressed as a fraction in standard English. 8, 3/4. Fractions are included in wholes. Numbers are stated in mathematics as the ratio of the numerator to the denominator. In simple fractions, each of these is an integer. A complicated fraction contains a fraction in either the numerator or denominator. There is a difference between the numerators and denominators of true fractions. A sum that is a fraction of a whole is referred to as a fraction. You may assess it by dissecting the whole into smaller pieces. For example, 12 is used to represent one-half of a whole number or object.

The missing length the right triangle to the nearest tenth is 8.8 units.

The figure in the image is a right traingle.

To solve for the second leg of the right triangle given the first leg and hypotenuse, we can use the Pythagorean theorem.

It states that the sum of the squares of the two legs is equal to the square of the hypotenuse.

a² + b² = c²

Let's denote the second leg by 'b'. Then we have:

2² + b² = 9³

Simplifying the equation:

4 + b² = 81

Subtracting 4 from both sides:

4 - 4 + b² = 81 - 4

b² = 77

Taking the square root of both sides:

b = √77

b = 8.8 units

Therefore, the second leg of the right triangle is 8.8 unit.

Therefore, the combined volume of the two rectangular prisms is 132 cubic units.

2-D enclosed shapes with four sides, four corners, and four right angles are called rectangles. A rectangle has two equal and parallel opposite sides.

To determine the combined volume of the two rectangular prisms shown in the diagram, we need to find the sum of their individual volumes. The volume of a rectangular prism is given by the formula:

Volume = length x width x height

In the diagram, we can see that the first rectangular prism has a length of 5 units, a width of 3 units, and a height of 4 units. The second rectangular prism has a length of 6 units, a width of 4 units, and a height of 3 units.

To find the volume of the first rectangular prism, we can use the formula:

Volume of first prism = length x width x height

Volume of first prism = 5 units x 3 units x 4 units

Volume of first prism = 60 cubic units

To find the volume of the second rectangular prism, we can use the same formula:

Volume of second prism = length x width x height

Volume of second prism = 6 units x 4 units x 3 units

Volume of second prism = 72 cubic units

Finally, to find the combined volume of the two prisms, we just need to add their individual volumes:

Combined volume = Volume of first prism + Volume of second prism

Combined volume = 60 cubic units + 72 cubic units

Combined volume = 132 cubic units

Therefore, the combined volume of the two rectangular prisms is 132 cubic units.

The answer as a fraction in lowest terms is 4/81, and the denominator is 81.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

There are 4 green card, 2 red cards, 3 blue cards

Now,

If the first card drawn is red and is replaced before the second draw, then the probability of drawing a red card on the second draw is the same as the probability of drawing a red card on the first draw, which is 2/9 (since there are 2 red cards out of a total of 9 cards).

To find the probability of drawing two red cards, we need to multiply the probability of drawing a red card on the first draw (which we know is 2/9) by the probability of drawing a red card on the second draw, which is also 2/9 (since the first card is replaced).

So the probability of drawing two red cards with replacement is:

Answer:

The answer is 1/25

Step-by-step explanation:

We have a right triangle with sharp angles measuring 30 and 60 degrees, proving the assertion "Triangle with angles A= 30 degrees, B= 60 degrees, C= 90 degrees" to be true.

To assess whether the supplied angles may form a triangle, we can use the knowledge that the total of the angles in a triangle is always 180 degrees. Let's figure up the angles' total:

180 degrees is equal to A + B + C = 30 + 60 + 90.

The supplied angles can definitely form a triangle because the sum of the angles is 180 degrees. We can now utilise the data to identify the kind of triangle.

The angles indicate that a right triangle with a 90-degree angle (angle C) and acute angles of 30 degrees and 60 degrees (angles A and B) exists (angle B).

The measurements of angles A and B are compatible with the available information since the total of the acute angles in a right triangle is always 90 degrees.

Step-by-step explanation:  

The factored form of the polynomial  f(x) = x³ - 7x² + 9x - 63 is,

(x - 7)(x² + 9).

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A polynomial f(x) = x³ - 7x² + 9x - 63.

Now, If x = 7 is an x-intercept then one root(cuts the x-axis) is 7 and one factor is (x - 7).

Now, Factoring(long division) f(x) = x³ - 7x² + 9x - 63 by (x - 7) we have,

(x³ - 7x² + 9x - 63) = (x - 7)(x² + 9).

Answer: To solve the problem, we need to subtract the number of points scored on touchdowns from the total number of points to find out how many points were scored on field goals.

133 points - (number of touchdowns x 7 points per touchdown) = points scored on field goals

We don't know the number of touchdowns, but we can use the fact that each touchdown is worth 7 points to write:

133 points - 7x = points scored on field goals

Now we can divide the points scored on field goals by the value of each field goal to find the number of field goals:

(points scored on field goals) / (3 points per field goal) = number of field goals

Putting it all together:

133 points - 7x = points scored on field goals

(points scored on field goals) / (3 points per field goal) = number of field goals

We need to solve for x, the number of touchdowns. We can start by isolating points scored on field goals:

133 points - 7x = points scored on field goals

points scored on field goals = 133 points - 7x

Now we can substitute this expression into the second equation:

(133 points - 7x) / (3 points per field goal) = number of field goals

Simplifying:

44.33 - 2.33x = number of field goals

Since the number of field goals must be a whole number, we can try different values of x until we find an integer solution. For example, if we assume that the Bobcats scored 16 touchdowns, then:

133 points - 7(16) = 21 points scored on field goals

21 points scored on field goals / 3 points per field goal = 7 field goals

Therefore, the Bobcats kicked 7 field goals.

No, -(p « › q) and p «> -q are not logically equivalent.

When two logical assertions have the same truth value for all conceivable truth value assignments to their constituent propositions, the two statements are said to be logically equivalent. In other words, two assertions are comparable logically if and only if all feasible permutations of the truth values of their component propositions are equal.

First, let's rewrite the statements using the standard logical operators of negation, conjunction, and implication:

-(p « › q) is equivalent to ¬(p ∧ ¬q)

p «> -q is equivalent to ¬p → ¬¬q, which simplifies to p → q

Now, we can construct a truth table with columns for p, q, ¬(p ∧ ¬q), and p → q:

p |      q |   ¬(p ∧ ¬q)    |    p → q

We can see that the truth values of the two statements are not always the same.

Step-by-step explanation:

Using the roots of the given equation, x²+x-6=0, the value of the expression, 2β²-3α², is -19

From the question, we are to evaluate the given expression.

In order, to evaluate the expression, we will solve the given quadratic equation

To solve x²+x-6=0, we can use factoring method

Solving the equation

x² + x - 6 = 0

(x + 3)(x - 2) = 0

Setting each factor equal to zero, we get:

x + 3 = 0 or x - 2 = 0

Solving for x in each case, we get:

x = -3 or x = 2

So the solutions to the equation are x=-3 and x=2.

Since α<β

Thus,

α = -3 and β = 2

Then,

2β²-3α²

= 2(2)² -3(-3)²

= 2(4) -3(9)

= 8 - 27

= -19

Hence, the value is -9
