Angle sum theorem y=? Degrees

Answer:

False

Step-by-step explanation:

a+(-a)=a-a = 0 which means irrational numbers are not closed under addition or subtraction.

False. Irrational numbers are not closed under subtraction.

Given data:

Closure under subtraction means that if you subtract two irrational numbers, the result will always be another irrational number.

However, this is not true for irrational numbers.

For example, consider the irrational numbers √2 and √2 + √2. Both of these numbers are irrational. However, when we subtract √2 from √2 + √2, we get:

(√2 + √2) - √2 = √2

The result, √2, is still an irrational number. But if we subtract two irrational numbers like √2 from √2, we get:

√2 - √2 = 0

The result, 0, is a rational number, not an irrational number.

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "/-32" was replaced by "/(-32)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

f/(-32)-(-31)=0

Step by step solution :

Rewriting the whole as an Equivalent Fraction

2.1 Subtracting a whole from a fraction

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

-31 -31 • -32

-31 = ——— = —————————

1 -32

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

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

f • -1 - (-31 • 32) 992 - f

When a fraction equals zero

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

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 :

992-f = 0

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

the answer is f = 992

16xb=144

b=9

perimeter=2(l+b)

=2(16+9)

=50 cm

Answer: 50cm squared

Step-by-step explanation:

First we need to find the side lengths,

In order to find the area you do,

A = Length x height

we know that the area is 144 and the length is 16.

144=16 x height

144 = 16 x ?

So know we need to find the height, so we do 144/16= 9

so the height 9 cm.

The question is not asking for the height, but the peremeter.

Peremeter = (Length x 2) + (height x 2)

peremeter= 16 x 2 + 9 x 2

peremeter = 32+18

peremeter = 50 cm squared

so the peremeter is 50 cm squared.

As terms help compensate for a quadratic equation. It can indeed be solved in several ways, and the calculation of the equation can be defined as follows:

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:

[tex]\to[/tex] ax² +bx +c = 0

[tex]\to[/tex] a= 1

[tex]\to[/tex] b=-5

[tex]\to[/tex] c=3

Appling the value into the Shreedhara Acharya's formula:

[tex]\to x = \frac {- b \pm \sqrt{ b^2 - 4ac } } { 2a}\\\\\to x = \frac {- (-5) \pm \sqrt{ (-5)^2 - 4\times 1 \times 3 } } { 2\times 1}\\\\\to x = \frac {+5 \pm \sqrt{ 25 - 12} } { 2}\\\\\to x = \frac {5 \pm \sqrt{ 13} } { 2}\\\\\to x = \frac {5 \pm 3.6} { 2}\\\\\to x = \frac {5 + 3.6 } { 2} \ \ \ \ \ \ OR \ \ \ \ \ \ \ x = \frac {5 - 3.6} { 2}\\\\\to x = \frac {8.6 } { 2} \ \ \ \ \ \ OR \ \ \ \ \ \ \ x = \frac {1.4} { 2}\\\\\to x = 4.3 \ \ \ \ \ \ OR \ \ \ \ \ \ \ x =0.7\\\\[/tex]

Therefore, the value of x is "4.3, 0.7".

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]

[tex]Probability = 0.4[/tex]

Answer:

Option A : 29 is the correct answer.

Step-by-step explanation:

Given that:

Number of trees planted by Tim = 86

Percent of trees with white flowers = 34%

Number of trees = 34% of 86

Number of trees = [tex]\frac{34}{100}*86[/tex]

Number of trees = 0.34 * 86

Number of trees = 29.24

Rounding to nearest whole number

Number of trees = 29

Hence,

Option A : 29 is the correct answer.

the decay factor for the given decay rate is 0.999

Given :

In recent years, Japan's population has been declining at a rate of 0.1% per year.

we need to find the decay factor for the given exponential rate.

The rate of decay is 0.1%. To remove percentage we divide by 100

so , [tex]\frac{0.1}{100}=0.001[/tex]

The decay rate is 0.001

To find out decay factor , we subtract decay rate from 1

decay factor is 1- decay rate

Decay factor is 1-0.001=0.999

So the decay factor for the given decay rate is 0.999

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.

Answer:

a) $96     b) 4.85%

Step-by-step explanation:

Cash cost: 4400

10% down: 4400 * 10% = 440

Rest cost she owed: 4400 - 440 = 3960

6 month paid: 676 * 6 = 4056

Finance interest paid: 4056 - 3960 = 96

calculate by simple interest rate (r: annual rate): 3960 * r * t     ( t = 6 month = 1/2 year)

3960 * r * 6/12 = 96

r = 0.0485   (4.85%)

check: 3960 * ( 1 + 4.85% * 6/12) = 4056 = 676 * 6
