Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the squares share one side with the rectangle. The total area of the constructed figure is 120 cm2. What is the perimeter of the rectangle?

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Probability is measured as

[tex]\frac{favourableoutcome}{count}[/tex]

The favourable outcome is obtaining roll > 4, that is a 5 or 6

P( > 4 ) = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

Answer:

A = 75°

B = 90°

C = 15°

Step-by-step explanation:

The diagram tells us that C = 15°.

The diagram places a square in the angle of B, showing you the angle is a 90° right angle.

You can solve for A because all angles of a triangle must equal 180°. 180° - 90° (B) = 90°. 90° - 15° (C) = 75°, the measure of A.

Answer:   There are two points of intersection (2, 4) and (-4, -2)

Step-by-step explanation:

x - y + 2 = 0     →       x = y - 2

Use Substitution Method:

x² + y² = 20

(y - 2)² + y² = 20              replaced x with (y - 2)

y² - 4y + 4 + y² = 20        expanded (y - 2)²

2y² - 4y + 4 = 20             added like terms

2y² - 4y - 16 = 0               subtracted 20 from both sides

y² - 2y - 8 = 0                  divided both sides by 2

(y - 4)(y + 2) = 0               factored

y - 4 = 0    and      y + 2 = 0       applied Zero Product Property

y = 4        and       y = -2

Input the y-values into x = y - 2 to solve for x.

y = 4;   x = 4 - 2                      y = -2;    x = -2 - 2

           x = 2                                         x = -4

      (2, 4)                                         (-4, -2)

Answer:

g(f(0)) = 6

Step-by-step explanation:

Evaluate f(0 ) and substitute this value into g(x)

f(0) = 0² = 0 and

g(0) = 0 + 6 = 6

⇒ g(f(0)) = 6

The value of g(f(0)) is 6.

If two functions f(x), g(x) are present , then (f o g) of x is also known as a composite function and it is mathematically denoted as f(g(x)) or (f ∘ g)(x). It means that x = g(x) should be substituted in f(x). It is an operation that combines two functions to form another new function.

Given , f(x) = [tex]x^{2}[/tex]  and  g(x) = x + 6

We have to find g(f(0)).

To get the value of this composite function g(f(x)), we first have to find the value of f(x) at the given value x = 0 and then substitute the value of f(x) into g(x).

⇒ f(0) = 0.

∴ g(f(0)) = g(0) = 0 + 6 = 6.

Therefore we have the value of g(f(0)) as 6.

The query pertains to 'linear recurrence relations' in Mathematics, particularly concerning high school algebra and series expansions, such as the binomial theorem, and plotting data on a logarithmic scale.

The term linear recurrence relation refers to a sequence of numbers where each term is a linear combination of previous terms. The relationship is defined by two aspects: the number of terms that go into the combination (order of the relation), and the coefficients of each of those terms. A classic example of a linear recurrence relation is the Fibonacci sequence, where each term is the sum of the two preceding terms.

When addressing series expansions like the binomial theorem, it is an expression that allows us to expand polynomials raised to a power in a series format. The theorem is a key concept in algebra and is particularly useful for calculating powers of binomials and deriving coefficients of individual terms within expanded polynomials.

To plot data like the recurrence interval on a logarithmic scale, it is essential to understand that each increment on the axis represents a multiplication by a certain factor, rather than a linear addition. This type of representation is particularly useful when dealing with data that varies by orders of magnitude.

The volume of a hemisphere with a radius of 5 inches is calculated by first determining the volume of a full sphere using the formula V = (4/3)πr³, and then dividing that by 2. The final volume of the hemisphere is 261.7994 cubic inches.

Volume of a Hemisphere

The question involves finding the volume of a hemisphere, which is half of a sphere, with a given radius of 5 inches. First, we would calculate the volume of a full sphere using the formula V = (4/3)πr³, and then divide that by 2 to get the hemisphere volume. Therefore, for a sphere with a radius of 5 inches:

Volume of the sphere, V = (4/3)π × 5³.

Volume of the hemisphere = V/2.

After performing the calculations:

Volume of the sphere, V = (4/3)π × 125 = 523.5988 cubic inches.

Volume of the hemisphere = 261.7994 cubic inches.

To find the probability of not rolling factors of 6 on both six-sided dice, multiply the individual probabilities of rolling a 4 or 5 on each die. The probability is 1/9.

The factors of 6 are 1, 2, 3, and 6. Therefore, the outcomes that are not factors of 6 are 4 and 5.

Since each die has six faces, the total number of possible outcomes when rolling two dice is 6 x 6 = 36.

Of these 36 possible outcomes, we need to count how many do not involve factors of 6. For each die rolled independently, we have 2 outcomes that are not factors of 6: {4, 5}.

So, we need to calculate the product of these individual probabilities to find the probability of both dice showing a non-factor of 6.

For a single die, the probability of rolling a non-factor of 6 (either a 4 or a 5) is 2/6 or 1/3, since we have 2 favorable outcomes out of 6 possible ones.

To find the probability for both dice, we multiply these individual probabilities:

Probability of not rolling a factor of 6 on both dice = (1/3) x (1/3) = 1/9.

This is the product rule in probability, which tells us that the probability of two independent events both happening is the product of their individual probabilities.

Therefore, the probability of not rolling a factor of 6 on both dice is 1/9.

Using Boyle's law, which states volume and pressure of a gas at constant temperature are inversely proportional, we find that at a pressure of 30 pounds per square inch, the volume will be 12 cubic feet.

The concept behind your question involves Boyle's law, which states the volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured. This means as pressure increases, volume decreases and vice versa while maintaining the same temperature.

To solve this, we can use the mathematical expression for Boyle's law: P₁V₁ = P₂V₂.

Where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume. Applying these values: 24 pounds per square inch * 15 cubic feet = 30 pounds per square inch * V₂. By rearranging the equation and solving for V₂, we get: V₂ = (24 pounds per square inch * 15 cubic feet) / 30 pounds per square inch = 12 cubic feet.

Therefore, when the pressure is 30 pounds per square inch, the volume will be 12 cubic feet.

Answer:

A=54in²

Step-by-step explanation:

The area of the L-shaped figure formed is 225 square inches.

To find the area of the L-shaped figure formed after cutting corners, start by calculating the area of the square from which the corners were removed.

The larger square has sides of length 15 inches, so its area is 15 x 15 = 225

When you cut corners of 9 inches by 9 inches from each corner of the larger square, you effectively create a smaller square. Since each side of the smaller square is 9 inches shorter than the larger square, its side length is -

15 - 2 x 9

= - 3

However, a negative side length is not possible, so we adjust it to zero. This implies that there's no square left after cutting off such large corners.

The area of the L-shaped figure is the difference between the area of the larger square and the area of the smaller square:

Area of L-shaped figure=Area of larger square−Area of smaller square

= 225 - 0

= 225

Thus, the area of the L-shaped figure formed is 225 square inches.

Answer:  y = x

Step-by-step explanation:

First, find the point where 5x - 2y + 3 and 4x - 3y + 1 intersect using the Elimination Method.

5x - 2y + 3 = 0  →  3(5x - 2y + 3 = 0)  →  15x - 6y + 9 = 0

4x - 3y + 1 = 0   → -2(4x - 3y + 1 = 0)  →   -8x + 6y - 2 = 0

                                                                 7x         + 7 = 0

                                                                 7x               = -7

                                                                   x               = -1

5x - 2y + 3 = 0

5(-1) - 2y + 3 = 0

-5 - 2y + 3 = 0

    -2y  - 2 = 0

    -2y        = 2

        y        = -1

(-1, -1)

Next, find the point where x = y and x = 3y + 4 intersect using the Substitution Method.

x = y

x = 3y + 4    →    y = 3y + 4

                      -2y = 4

                         y = -2

x = y

x = -2

(-2, -2)

Now, find the line that passes through (-1, -1) and (-2, -2) using the Point-Slope formula.  (x₁, y₁) = (-1, -1)  and m = 1

y - y₁ = m(x - x₁)

y + 1 = 1(x + 1)

Answer:

each section will equal 2.5 miles

Step-by-step explanation:

if you divide 10 from 4 you get 2.5

To divide a 10-mile bike race into four equal sections, we calculate the length of one section by dividing 10 miles by 4, resulting in each section being 2.5 miles long.

The question pertains to the division of a 10-mile bike race into four equal sections. To find the length of each section, we divide the total distance of the race (10 miles) by the number of sections (4). This calculation will give us the length of one section.

10 miles \ 4 sections = 2.5 miles per section.

Thus, each section of the bike race would be 2.5 miles long. This application of division in real-world situations like races and marathons is a fundamental concept in mathematics, allowing participants and organizers to understand and manage distances more effectively.
