By AA similarity Triangle PQR and TQS are similar.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.

Given:

As, PR || TS then

<RPQ = <TSQ (Alternate Interior Angle)

< <QTS = <QRP (Alternate Interior Angle)

So, Triangle PQR and TQS are similar by AA similarity criteria.

Step-by-step explanation:

For rectangle ABCD, the value of x is 6.44 inches

Consider the following diagram.

From this figure we can observe that the dimansions of the rectangle: length is given by expression (7x + 1) and width is given by expression 'x'

We know that tha formula for the perimeter of the rectangle,

P = 2 × (length + width)

Here, the perimeter of rectangle ABCD is 105 inches.

Using above formula of perimeter we get an expression,

P = 2 × ((7x + 1)+ x)

105 = 2 × (8x + 1)

We solve above equation for x.

105/2 = 8x + 1

52.5 - 1 = 8x

8x = 51.5

x = (51.5)/8

x = 6.44 inches

Answer:

MN ≈ 92.1

Step-by-step explanation:

given the figures are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{MN}{IJ}[/tex] = [tex]\frac{KL}{GH}[/tex] ( substitute values )

[tex]\frac{MN}{21}[/tex] = [tex]\frac{57}{13}[/tex] ( cross- multiply )

13 MN = 21 × 57 = 1197 ( divide both sides by 13 )

MN ≈ 92.1 ( to the nearest tenth )

Answer:

10+5v=70

Step-by-step explanation:

this is because you need to consider the outright monthly cost of $10 first. then you don't know how many visits you'll need so you have to fill in v and multiply it by the cost per visit. and it must equal 70 so that it is equal to the other membership.

The equation 70 = 10 + 5v is used to determine the number of visits per month needed for two membership types to cost the same. Solving the equation would provide that 12 visits a month will make both memberships cost the same.

The subject of this question is Mathematics, and it is related to the topic of linear equations. Given the problem, we know that there are two types of membership options:

Here, Y represents the total cost of the membership each month and v represents the number of visits to the water park per month. You can set these two equations equal to each other in order to find the number of visits (v) needed for the two membership types to cost the same amount:

70 = 10 + 5v

You solve the equation for v to get: v = (70 - 10) / 5 = 12

Therefore, it would take 12 visits per month for both memberships to cost the same.

Answer: To find the highest common factor (HCF) of two polynomials, we can use the Euclidean algorithm for polynomials. The Euclidean algorithm involves dividing the larger polynomial by the smaller polynomial and continuing the division process until the remainder is zero. The last non-zero remainder is the HCF of the two polynomials.

In this case, we have:

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

= x^3 + x^2 - 3x

Now, we divide x^3 + x^2 - 3x by x^3 - x

x^3 + x^2 - 3x = x^3 - x * (1 + x - 3)

= x^3 - x * (x^2 - 2x + 3)

We cannot simplify this expression further, so the HCF of 2x^3 + x^2 - 3x and x^3 - x is x^3 - x.

The solution is, 35, lists of three elements can we make using the numbers 1, 2, 3, 4, and 5, if repetition is allowed.

In mathematics, a combination is a selection of items from a set that has distinct members, such that the order of selection does not matter.

here, we have,

Given data:

{1 ,2, 3 ,4, 5}

Formula for combinations is used since the order does not matter and repetition is allowed.

nCr = (n + r -1) /(r! * (n-1)!)

where n is the total number of items and r is the items to be picked

now, we get,

5C3 = (5 + 3 - 1)! /(3! * (5 -1)!

5C3 = 7!/(3! *4!) Simplifying the factorials)

5C3 = 5040/(6*24)

5C3 =5040/144

According to the question, the depth of the water is 11 feet.

The depth of something refers to how deep or far down it goes. It can refer to physical measurements such as the depth of a lake or ocean or the depth of a hole, or to metaphorical measurements such as the depth of knowledge or the depth of emotions. In terms of physical measurements, depth is usually referred to in terms of length or distance.

Let x be the depth of the water

The reed is 11 feet tall (10 feet in the water + 1 foot above the water)

The circumference of the pool is 10π feet

The volume of water in the pool = (circumference x depth) = 10πx

The volume of the reed = (area of base x height) = π(5²) x 11 = 275π

The total volume of the pool and reed = 10πx + 275π

10πx + 275π = 10π(11)

10πx = 110π

x = 11

Therefore, the depth of the water is 11 feet.

Answer: This question can be solved using exponential growth formula:

N = N0 * e^(rt)

Where N is the number of smartphones, N0 is the initial number, r is the growth rate, t is the number of years and e is the base of the natural logarithm (approximately equal to 2.718).

First, we need to find the growth rate:

r = (ln(N/N0)) / t

Using the data from 2010 and 2011:

r = (ln(72.9/39.99)) / 1

Next, we can find the year when the number of smartphones sold exceed 200 million:

N = 200 million

N0 = 39.99 million

t = (ln(N/N0)) / r

t = (ln(200/39.99)) / r

To find the year, we need to add t to the initial year 2010.

The number of smartphones the brand sold exceeded 200 million in the year 2023.

Step-by-step explanation:

The value of "n" is approximately 2.6666667.

Exponent is a mathematical operation that represents repeated multiplication of the same number.

We can start by simplifying the left side of the equation:

(2^(2n))^4 * (2^n)^2 = 2^16 - 1

Using the exponent rules:

a^m * a^n = a^(m + n)

We can simplify the left side of the equation further:

2^(4n + 2n) = 2^16 - 1

Combining the exponents:

2^(6n) = 2^16 - 1

Now we can use the fact that if a^m = a^n, then m = n to solve for "n":

6n = 16

Dividing both sides by 6:

n = 16/6 = 8/3

Therefore, The value of "n" is approximately 2.6666667.

A time series is a set of observations collected over a period of time, and it can be decomposed into various components, including trend, cyclical, seasonal, and random variation.

The trend component represents the overall pattern of the time series, such as an upward or downward trend. The cyclical component represents the repeating patterns that are not related to the regular seasons or calendar years. The seasonal component represents the regular variations that occur at specific times of the year, such as the summer months in this example. The random variation represents the unpredictable fluctuations in the time series.

Answer:

each lower base angle is supplementary to the upper base angle on the same side.

∠ A + 42° = 180° ( subtract 42° from both sides )

∠ A = 138°

∠ B + ∠ C = 180 , that is

12x - 3 + 9x - 6 = 180

21x - 9 = 180 ( add 9 to both sides )

21x = 189 ( divide both sides by 21 )
