The Length is 5 inches and the Breadth is 15 inches

What is Perimeter?

A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter. There are various practical applications for calculating the perimeter.

Solution:

Perimeter of Rectangle = 2*(Length + Breadth)

According to the question

Breadth = 3*Length

Perimeter = 40

40 = 2*(Length + 3*Length)

20 = 4*Length

Length = 5 inch

Breadth = 15 inch

Answer:

27a + 72

Step-by-step explanation:

Open the brackets

9(3a) + 9(8)

27a +72

Answer:

27a + 72

Step-by-step explanation:

9(3a + 8)

Using the distributive property, we can multiply 9 by everything in parentheses, which now gives us: 27a + 72

We cannot simplify this further, as we have an unknown value in the variable a, thus we cannot apply 72 to 27a, or inverse.

Meaning that, the answer is 27a + 72

The total distance walked in each case is given below;

Jada's pet turtle walked 10 feet, and then half that length again

Total distance = 10 + (1/2 of 10)

= 10 + (1/2 × 10)

= 10 + 5

= 15 feet

Jada's pet baby brother walked 3 feet, and then half that length again

Total distance = 3 + (1/2 of 3)

= 3 + (1/2 × 3)

= 3 + 1.5

= 4.5 feet

Jada's pet hamster walked 4.5 feet, and then half that length again

Total distance = 4.5 + (1/2 × 4.5)

= 4.5 + 2.25

= 6.75 feet

Jada's pet robot walked 1 foot, and then half that length again

Total distance = 1 foot + (1/2 × 1)

= 1 + 0.5

= 1.5 feet

A person walked x feet, and then half that length again

Total distance = x + (1/2 × x)

= x + 1/2x

= 1.5x feet

In conclusion, the total distance is calculated by adding the initial distance and additional distance

For every prime power pn that divides the order of a finite group G, the Sylow theorems ensure the existence of a subgroup of G of order pn.

What is subgroup?

Sn1 is transitive because normal subgroups of primitive groups are, and as a result, pn1! A transitive group of degree p's centralizer now has order. Given that p is a prime number and n is a positive integer, let G be a finite group of order pn. Assume that H is an index-containing subgroup of G. Note that you can prove it for any boolean interval of rank 4 if you also know the normal subgroups of G. A homomorphism is produced by the left multiplication that G naturally performs on G/H.

Number of T-Shirts = y

Equation 1:

x + y = 84 -----------(i)

Equation 2:

25x + 9.5y = 1046 ----------(ii)

Multiplying Equation 1 by 25

25x + 25y = 2100 ---------(iii)

In solving the equation, the student did the division wrong, and 29.4/4.2 = 7 which is correct.

Multiplication is the opposite of division.

If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group.

Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

So, the equation is:

4.2p = 29.4

Let's solve as follows:

4.2p = 29.4

p = 29.4/4.2

p = 7

So, the value of p comes to 7.

Where in the image, the value of p is 123.48 which is wrong as the division is not done properly.

The value of t for the given triangle angle will be equal to 1.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given the three angles of the triangle are 111,34, and 35t. The value of t will be calculated as,

35t + 111 + 34 = 180

35t = 180 - 111 - 34

Answer:

To apply the distributive property using the greatest common factor (GCF) to write an equivalent expression for 0.3x - 2.7, we need to find the GCF of the coefficients of the terms in the expression. In this case, the GCF is 0.3, so we can write the expression as 0.3(x - 9). This is an equivalent expression to 0.3x - 2.7, because multiplying 0.3 by the difference of x and 9 produces the same result as subtracting 2.7 from 0.3x.

After solving the angles, the measure of angle x is 145°.

When two straight lines or rays intersect at a single endpoint, an angle is created.

The vertex of an angle is the location where two points come together.

The Latin word "angulus," which means "corner," is where the term "angle" originates.

The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.

A geometrical shape called an angle is created by connecting two rays at their termini.

In most cases, an angle is expressed in degrees.

(Refer to the image attached below)

We can see that ∠ABC is a straight angle.

∠ABC = ∠ABD + ∠DBC where ∠ABD is x.

Now, solve for x as follows:

∠ABD + ∠DBC = ∠ABC

x + 35 = 180

x = 180 - 35

x = 145°

Therefore, after solving the angles, the measure of angle x is 145°.

Answer:

To find the value of the quartiles, we need to first find the median of the data set. The median is the middle value of the data set, or the value that separates the lower half of the data from the upper half. In this data set, the median is 2.5, as it is the middle value when the data is arranged in ascending order.

Once we have the median, we can find the first and third quartiles. The first quartile, also known as Q1, is the median of the lower half of the data set, and the third quartile, also known as Q3, is the median of the upper half of the data set. In this data set, the lower half of the data is {1.3, 1.5, 1.7, 2, 2.5}, and the upper half of the data is {2.7, 2.9, 3, 3.1}. The median of the lower half is 1.7, and the median of the upper half is 2.9.
