2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using -32 as the denominator :

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

3.1 When a fraction equals zero

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

992-f

————— • 32 = 0 • 32

Now, on the left hand side, the 32 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

Solving a Single Variable Equation:

3.2 Solve : -f+992 = 0

Subtract 992 from both sides of the equation :

-f = -992

Multiply both sides of the equation by (-1) :

f = 992

Answer:

83 degrees

Step-by-step explanation:

In order to find the angle x, you need to find all the angles inside the triangle.

You have already been given the angle 43 degrees, which is inside the triangle, but you dont know the other angle inside the triangle.

However, you have been given the angle 126 degrees, which is outside the triangle.

You can see that the base of the triangle consists of a straight line. And the angles on a straight line add up to 180 degrees.

So to find the missing internal angle of the triangle:

180 - 126 = 54 degrees.

Now you have 2 internal angles, but you are missing one, which is x.

all the angles in a triangle add up to 180 degrees.

T

herefore to find x, you add the two internal angles of the triangle and then subtract it from 180 degrees:

180 - (54 + 43) = 83 degrees

Sorry for the longwinded explanation, but I hope it helps.

Which conclusion is correct about the population of State A and State B?

a. The original population of State B was half of the original population of State A.
b. The original population of State A was half of the original population of State B.
c. The original population of State B was one-fourth of the original population of State
d. The original population of State A was one-fourth of the original population of State

Answers

-- State-B . . . Population = 2 · (1.08)ˣ

' x ' = number of years after the original population

At the beginning, x=0.

Any quantity raised to the zero power = 1.

At the beginning, when x=0, the original populations were

What is the standard form of the polynomial

Writing the polynomial according to the decreasing value of the exponents, the polynomial in standard form is given by:

[tex]p(x) = -6x^4 + 14x^2 + 7x - 125[/tex]

In a standard form polynomial, the terms with the highest exponents always come first.

In this problem, the exponents are, in order, 1, 0, 4 and 2. Thus, first should come the term with exponent 4, then the term with exponent 2, then exponent 1 and finally the term with exponent 0. Thus, the polynomial in standard form is given by:

Quadratic Equation:

All quadratic equations can be stated as ax²+bx+c=0, where can not be equal to 0, but can.

Following are solutions to given equation:

[tex]\to[/tex] x² – 5x + 3 = 0

Comparing the value with the standard equation:

Appling the value into the Shreedhara Acharya's formula:

Step-by-step explanation:

Let us rearrange this equation by dividing both sides by (-3):

Slope of the line  -3y = 12x + 6 is -4.

What is slope intercept - form of line?

The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as:

y = mx + b.

Given,

Equation of the straight line

-3y = 12x + 6

Dividing by -3 on both side

y = 12x/-3 + 6/-3

y = - 4x - 2

Comparing the above equation with slope - intercept form equation of line

y = mx + b

where m is slope and b is vertical intercept.

Slope of the given line

m = -4

Hence, - 4 is the slope of the line -3y = 12x + 6 .

tan theta = -1

we know tan = opposite/ adjacent

So opposite/adjacent = -1

Multiply by adjacent on each side

opposite = - adjacent

We also know from pythagorean theorem that

opposite ^2 + adjacent ^2 = hypotenuse ^2

Substituting in for adjacent

opposite ^2 + (-opposite ) ^2 = hypotenuse ^2

opposite ^2 + opposite ^2 = hypotenuse ^2

2 opposite ^2 = hypotenuse ^2

Taking the square root on each side

sqrt(2 opposite ^2)   =  sqrt(hypotenuse ^2)

sqrt(2) opposite = hypotenuse

We are now set to find the sec

              = sqrt(2) opposite/ adjacent

Replace the opposite = -adjacent

Step-by-step explanation:

Rest cost she owed: 4400 - 440 = 3960

The perimeter of the rectangle is 34 cm. The perimeter of the triangle is 30 cm. Find the value of m.

a. 5 cm
b. 6 cm
c. 7 cm
d. 8 cm


Please select the best answer from the choices provided​

Answers

Answer:

a. 5cm

Step-by-step explanation:

r. m+m+n+n= 34

t. m+n+n+1=30

r. 2m + 2n =34

t. m + 2n + 1 = 30

after multiple by negative t row

t. -m -2n -1 = -30

and combine the 2 rows

2m -m +2n - 2n -1 = 34 - 30

m - 1 = 4

and we add one to each side of the operation

m - 1 + 1 = 4 + 1

m = 5

The value of m is 5 cm. Therefore, option A is the correct answer.

What is the perimeter?

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

Given that, the perimeter of the rectangle is 34 cm.

We know that, the formula to find the perimeter of rectangle is 2(Length+Width)

From the figure, 2(m+n)=34

m+n=17 -------(I)

The perimeter of the triangle is 30 cm.

From the figure, m+n+n+1=30

m+2n=29 -------(II)

From equation (I), we have m=17-n

Put m=17-n in equation (II), we get

17-n+2n=29

n=12 cm

Substitute n=12 in equation (I), we get

m=5 cm

The value of m is 5 cm. Therefore, option A is the correct answer.

In a bag, there are six white balls and four black balls. I take out two balls at random, one at a time, without replacement. What is the probability that the second ball I take is black

Answers

Answer:

[tex]Probability = 0.4[/tex]

Step-by-step explanation:

Given

[tex]White = 6[/tex]

[tex]Black = 4[/tex]

Required

Probability that second is black

This selection can be represented as:

(Black and Black) or (White and Black)

The probability of Black and Black is:

[tex]P(Black\ Only) = \frac{Black}{Total} * \frac{Black - 1}{Total - 1}[/tex]

1 is subtracted from the second fraction because it is probability without replacement

[tex]P(Black\ Only) = \frac{4}{10} * \frac{4- 1}{10 - 1}[/tex]

[tex]P(Black\ Only) = \frac{4}{10} * \frac{3}{9}[/tex]

[tex]P(Black\ Only) = \frac{2}{5} * \frac{1}{3}[/tex]

[tex]P(Black\ Only) = \frac{2}{15}[/tex]

The probability of White and Black is:

[tex]P(Black\ and\ White) = \frac{Black}{Total} * \frac{White}{Total - 1}[/tex]

1 is subtracted from the second fraction because it is probability without replacement

[tex]P(Black\ and\ White) = \frac{4}{10} * \frac{6}{10- 1}[/tex]

[tex]P(Black\ and\ White) = \frac{4}{10} * \frac{6}{9}[/tex]

[tex]P(Black\ and\ White) = \frac{2}{5} * \frac{2}{3}[/tex]

[tex]P(Black\ and\ White) = \frac{4}{15}[/tex]

So, the required probability is:

[tex]Probability = P(Black\ Only) + P(Black\ and\ White)[/tex]

[tex]Probability = \frac{2}{15} + \frac{4}{15}[/tex]

[tex]Probability = \frac{2+4}{15}[/tex]

[tex]Probability = \frac{6}{15}[/tex]
