The width of the rectangular will be x+4.

What is a rectangle?

Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. Various definitions include an equiangular quadrilateral, A closed, four-sided rectangle is a two-dimensional shape. A rectangle's opposite sides are equal and parallel to one another, and all of its angles are exactly 90 degrees. Quadrilaterals are typically four-sided closed shapes, and there are numerous varieties of them. Square, rectangle, rhombus, kite, and trapezoid are the most typical shapes. Four closed sides make up a quadrilateral. Quadrilaterals are the following figures: a four-sided figure. The form features a single set of parallel sides and no right angles.

Area of the rectangle is A = a*b

Given Length is = x+7

And  the area is x² +11x+28

So the width is = x² +11x+28 / x+7

x² +7x+4x+28/x+7

=(x+7)(x+4)/x+7

=x+4

Hence the width of the rectangular will be x+4.

Answer:

E

Step-by-step explanation:

The sum of a and b is obtained as follows:

a + b = 5.

The function for this problem is defined as follows:

f(x) = ax/[bx - 4]

f(1) = -2 means that when x = 1, y = -2, hence:

-2 = a/(b - 4)

a = -2b + 8

f(2) = 2 means that when x = 2, y = 2, hence:

2 = 2a/(2b - 4)

2a = 4b - 8

a = 2b - 4.

Equaling the two equations, the value of b is obtained as follows:

-2b + 8 = 2b - 4

4b = 12

b = 3.

Hence the value of a is ob:

a = 2b - 4

a = 2(3) - 4

a = 2.

Hence the sum is of:

a + b = 2 + 3

a + b = 5.

What is geometric progression?

A geometric progression often referred to as a geometric sequence, is a series of non-zero values where each term following the first is obtained by multiplying the preceding value by a constant, non-zero number known as the common ratio.

Here, we have

Given:  3rd term is 27 and whose 6th term is 8​

Let the GP terms are a, ar, ar², ar³, ar⁴ and ar⁵,

Given ar² = 27 and ar⁵ = 8

Take the ratio of the sixth term to the third term:

ar⁵ / ar² = 8/27 => r³ = (2/3)³

r = 2/3

We know that

ar² = a(2/3)² = 27

=> a(4/9) = 27

=> a = 27*9/4 = 243/4

So, the terms are 243/4, 243/4*(2/3), 243/4*(4/9), 243/4*(8/27), 243/4*(16/81), 243/4*(32/243)

= 243/4 + 27

= 60.75 + 27

= 87.75

Hence, the sum of the 1st and three-term of the GP is 87.75.

Probability that Erin selects a bulb for a yellow flower or a dahlia is 52.8%.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Given, by the table

Total number of flowers = 5+4+3+3+1+2+2+5+6+0+1+4 = 36

Number of yellow flowers = 4 + 1 + 5 + 1 = 11

Number of Dahlia flowers = 5 + 4 + 3 = 12

Number of yellow Dahlia = 4

Probability of selecting bulb for a yellow flower P(y)= 11/36

Probability of selecting bulb for dahlia P(d) = 12/36

Probability of selecting bulb for yellow Dahlia P(y and d) = 4/36

Probability of selecting bulb for yellow flower or dahlia

= P(y) + P(d) - P(y and d)

= 11/36 + 12/36 - 4/36

= (11 + 12 - 4)/36

= 19/36

= 0.528

= 52.8%

Hence, 52.8% is probability that she selects a bulb for a yellow flower or a dahlia.

The process of converting individual raw scores in a distribution to a set of scores for which we know the percentiles is known as "normalizing the data" or "standardizing the data."

The steps for standardizing the data are as follows:

Order the raw scores in the distribution from smallest to largest.

Assign each score a percentile rank. This is the percentage of scores in the distribution that are equal to or lower than the score. For example, if a score has a percentile rank of 75, it means that 75% of the scores in the distribution are equal to or lower than that score.

Convert the raw scores to standardized scores (also known as z-scores). This is done by subtracting the mean of the distribution from each score and then dividing by the standard deviation of the distribution. The resulting standardized score represents the number of standard deviations above or below the mean that the raw score falls.

The process of standardizing the data helps to put the raw scores into a common context, which makes it easier to compare scores from different distributions and to draw meaningful conclusions about the data. Additionally, standardized scores can be used to determine the probability of a score falling within a particular range.

Step-by-step explanation:

2(4.25y+7.5y-7.5+8)

2(11.75y+0.5)

2(11.75y) + 2(0.5)

23.50y + 1

Let's start by setting up a system of equations to represent the given information:

3r = m - 7

9r = m + 11

where r is the cost of one rose, and m is the total amount of money that Masha has.

We can solve this system of equations using the elimination method:

Multiplying the first equation by 3, we get:

9r = 3m - 21

Subtracting the second equation from this, we get:

0 = -4m - 32

Simplifying, we get:

m = -8

Therefore, Masha has $-8, which means she owes money. This indicates that there may be an error in the problem statement or data provided.

Answer:

Masha has 16 dollars.

Step-by-step explanation:

3x + 7 = Masha's total money

9x = Masha's total money + 11 (after borrowing)

We can use the first equation to find the value of 3x, which is Masha's total money if she buys three roses:

3x + 7 = Masha's total money

3x + 7 = Masha's total money

3x = Masha's total money - 7

We can substitute the second equation to solve for Masha's total money:

9x = Masha's total money + 11

9x = (3x + 7) + 11

9x = 3x + 18

6x = 18

x = 3

Now we know that one rose costs 3 dollars. We can use the first equation to find Masha's total money if she buys three roses:

3x + 7 = Masha's total money

3(3) + 7 = Masha's total money

9 + 7 = Masha's total money

Masha's total money = 16

The ratio of the CosA will be 12 / 37 for the right-angle triangle.

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 that there is a right angle triangle having the Hypotenuse = 37, Base = 12, and Height = 35.

The value of CosA will be calculated as:-

Answer: Given that a, b, and c form an arithmetic sequence, so they are equally spaced, meaning the difference between each of them is constant. Let's denote the common difference between a, b, and c as d.

So, we have:

a = b - d

c = b + d

Using these two equations, we can prove that 2^a, 2^b, and 2^c form a geometric sequence.

We have:

2^a = 2^b / 2^d

2^c = 2^b * 2^d

Since the product of two powers of the same base is equivalent to the power of the base with the sum of the exponents, we have:

2^a * 2^c = 2^b * 2^b * 2^d * 2^d = 2^(b+b+d+d) = 2^(2b+2d)

So, we have:

2^a * 2^c = 2^(2b+2d) = 2^(2b) * 2^(2d) = 2^b * 2^b * 2^d * 2^d = 2^b * 2^c

This means that 2^a, 2^b, and 2^c form a geometric sequence, with the common ratio of 2^d.
