The student solved the equation and determined that the solution was -2. This is wrong as the solution is 0.

An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.

This will be illustrated as:

1.5x - 2 = -2

Collect like terms

1.5x = - 2 + 2

1.5x = 0

Divide

x = 0/1.5

x = 0.

As per the concept of unitary method, there are 180.8 ml of the 65% mixture will you need to add to obtain the desired solution

Unitary method:

Basically, the way of finding out the solution of a problem by initially finding out the value of a single unit, and then finding out the essential value by multiplying the single unit value.

Given,

You need a 35% alcohol solution. On hand, you have a 300 mL of a 20% alcohol mixture. You also have 65% alcohol mixture.

Here we need to find how much of the 65% mixture will you need to add to obtain the desired solution.

Let us consider x be the amount of the 65%  alcohol needed (in milliliters.

Here the amount of the resulting 65%  alcohol solution will be is (x+15) milliliters.

So, the amount of the "pure" alcohol in 300 mL of the 20% alcohol solution is written as,

=> 0.20 x 300 mL.

And the amount of the "pure" alcohol in x mL of the 65% alcohol solution is written as,

=> 0.65 * x mL.

Therefore, the total amount of the "pure" alcohol in ingredients is the sum  and it can be calculated as,

=> 0.20*300 + 0.65*x mL.

So, it should be equal to the amount of the "pure" alcohol in the mixture, which is written as,

=> 0.35 * (x+15) ml.

Therefore, your "pure alcohol" equation is

=> 0.65* x + 0.20 * 300 = 0.35*(x+15).

When we simplify this one then we get the value of x as,

=> 0.65* x + 0.20 * 300 = 0.35*(x+15).

=> 0.65x + 60 = 0.35x + 5.25

=> 0.3x + 54.25

=> x = 180.8

Step-by-step explanation:

Form of an exponential function is

[tex]y = a \times b {}^{x} [/tex]

where a is the initial value, and b is the rate of growth

We know that when x=2

[tex]100 = a \times b {}^{2} [/tex]

when x=4

[tex]2500 = a \times b {}^{4} [/tex]

If we divide these two quantities we would get

[tex]25 = b {}^{2} [/tex]

[tex]b = 5[/tex]

So our rate of common growth is 5,

so b=5

[tex]y = a \times 5 {}^{x} [/tex]

We need to find the initial value, this means we solve for a.

[tex]100 = a \times 5 {}^{2} [/tex]

[tex]100 = a \times 25[/tex]

[tex]4 = a[/tex]

So our equation is

[tex]y = 4(5) {}^{x} [/tex]

The linear equation that represents the number of words Nebi types per minutes after the timer is started is: w = 50m + 250.

Linear equation can be written in the slope-intercept form as y = kx + b. To write this, find the values of the slope = m, and the y-intercept of starting value = b.

From the equation given, find the unit rate/slope, which is the number of words typed in one minute.

Thus, we have:

Slope/unit rate (m) = 150/3

m = 50 words per minute.

The y-intercept (b) is 250, because it is the initial/starting value.

Let w represent the total number of words, and m represents the minutes after the starting time.

To write the linear equation, substitute k = 50 and b = 250 into w = km + b:

w = 50m + 250

The factors of (24x⁶ - 1029y³) are 3, (2x² - 7x), (4x⁴ +14x²y+49y²)  

When a polynomial is factored, its prime factorization is used to break it down into the product of two or more other polynomials. Polynomials may be easily simplified with the use of factoring.

When a polynomial is factored, its factors are expressed as the polynomial's product. Finding the zeros of the polynomial expression or the values of the variables in the supplied expression are both made possible by factoring polynomials.

Here we have

24x⁶ - 1029y³  

Take 3 as common

=> 3(8x⁶ - 343y³)  

As we know 8 = 2³ and 343 = 7³

=> 3[(2x²)³ - (7y)³]  

From the algebraic identities

Take a = 2x² , b = 7y and apply above formula

=> 3[(2x² - 7x)((2x²)²+(2x²)(7y)+(7y)²)]  

=> 3 [ (2x² - 7x) (4x⁴ +14x²y+49y²)]  

Therefore,

(24x⁶ - 1029y³) = 3 (2x² - 7x) (4x⁴ +14x²y+49y²)

In accordance with Pythagorean theorem, no point is 4 units away from point M.

In this problem we find the coordinates of points A, B, C, whose coordinates are (- 4, 2), (2, 7) and (8, - 6), respectively, and the location of point M, whose coordinates are (- 4, - 6), all set on Cartesian plane. We need to determine if at least one of those three points (A, B, C) are four units away from point M. This can be checked by means of Pythagorean theorem:

AM = √[(- 4 - 2)² + [- 6 - (- 4)]²]

AM = √[(- 6)² + (- 2)²]

AM = 2√10 = √40

BM = √[(- 4 - 2)² + (- 6 - 7)²]

BM = √[(- 6)² + (- 13)²]

BM = √205

CM = √[(- 6 - 8)² + [- 4 - (- 6)]²]

CM = √[(- 14)² + 2²]

CM = 10√2 = √200

1997 for age 65 or older

Bachelor's degree or higher: The yellow bar starts at 75% and ends at 100%

To find how much percent of people 65 or older had a bachelor's degree in 1997, you subtract...100-75 = 25%

College/associate degree: 75 - 54 = 21%

High school graduates: 54 - 22 = 32%

Less than a High school diploma: 22 - 0 = 22%

Total: 25+21+32+22 = 100%

2007 for age 65 or older

Bachelor's degree or higher: 100 - 69 = 31%

College/associate degree: 69 - 46 = 23%

As per the given angle of elevation, the height of the building is 368.5 ft.

Angle of elevation:

Basically, an angle between the horizontal plane and line of sight from the observer's eye to some object above is known as angle of elevation.

Given,

The angle of elevation to the top of a Building in New York is found to be 2 degrees from the ground at a distance of 2 miles from the base of the building.

Here we need to find the height of the building and round to the tenths.

Here we know that the angle of elevation of the building in New York is written as,

=> θ = 2°

And the distance of observation point from the building is given as,

=> l = 2 miles

Here we know that, 1 miles = 5280 feet

So, the value of l in feet is,

=> l = 2 x 5280

=> l = 10560

Now, it is required to calculate the height of the building. Use the concept of trigonometry to find the height,

So, the height is calculated as,

=> tan θ =h/l

Apply the values on the formula, then we get,

=> tan 2° = h/10560

=> 0.0349 = h/10560

=> h = 0.0349 x 10560

=> h = 368.5 feet.

Therefore, the height of the building is 368.5 ft.
