Answer»

ANSWER:

Value \: of \:\frac{8^{\frac{1}{3}}\times (16)^{\frac{1}{3}}}{(32)^{\frac{-1}{3}}}=16

Step-by-step explanation:

\frac{8^{\frac{1}{3}}\times (16)^{\frac{1}{3}}}{(32)^{\frac{-1}{3}}}

=8^{\frac{1}{3}}\times (16)^{\frac{1}{3}}\times (32)^{\frac{-1}{3}}

/* By Exponential identity:

\boxed { \frac{1}{a^{-n}}=a^{n}}

=\SQRT[3]{8\times 16 \times 32}

=\sqrt[3]{2^{3}\times 2^{4}\times 2^{5}}

=\sqrt[3]{2^{3+4+5}}

=\sqrt[3]{2^{12}}

= 2^{\frac{12}{3}}

/* \boxed {(a^{m})^{n}=a^{mn}}*/

=2^{4}

=16

Therefore,

Value \: of \:\frac{8^{\frac{1}{3}}\times (16)^{\frac{1}{3}}}{(32)^{\frac{-1}{3}}}=16

Answer» Step-by-step explanation: Given If one NUMBER is selected from first 70 natural numbers, find the PROBABILITY that the number is a solution of x^2 + 2x > 4 Now probability is given by probability = number of FAVOURABLE outcomes / total number of possible outcomes. Now a number is selected at random from first natural numbers. So we get total number of outcomes will be 70 Favourable outcomes will be So x^2 + 2x > 4 Now TAKING 1 we get 1^2 + 2 (1) = 3 < 4 2^2 + 2(2) = 8 > 4 So all other numbers up to 70 will be greater than 4. So we have 70 – 1 = 69 So total number of favourable outcomes will be 69 Therefore probability will be 69 / 70 Reference link will be brainly.in/question/8619616

If one number is selected from first 70 natural numbers, find the probability that the number is a solution of x^2 + 2x > 4....Plz don't spam or I curse you for 13 Years of Badluck.

Answer»

Step-by-step explanation:

Given If one NUMBER is selected from first 70 natural numbers, find the PROBABILITY that the number is a solution of x^2 + 2x > 4

Now probability is given by probability = number of FAVOURABLE outcomes / total number of possible outcomes.
Now a number is selected at random from first natural numbers.
So we get total number of outcomes will be 70
Favourable outcomes will be
So x^2 + 2x > 4
Now TAKING 1 we get 1^2 + 2 (1) = 3 < 4
2^2 + 2(2) = 8 > 4
So all other numbers up to 70 will be greater than 4. So we have 70 – 1 = 69
So total number of favourable outcomes will be 69
Therefore probability will be 69 / 70

Connecting two nearby endpoints of the two chords (red line), and drawing its perpendicular bisector as well (red dashed line). The INTERSECTION of these two bisectors is the midpoint of the circle M.

3. The following real numbers have decimal expansions as given below. In each casedecide whether they are rational or not. If they are rational, and of the formyou say about the prime factors of q?(1) 43.123456789(ii) 0.120120012000120000...(1) 43.123456789

Answer»

Answer: 2^n × 5^m form

Step-by-step explanation: i ) Let X = p/q be a RATIONAL number , such

that the prime FACTORISATION of q is of the

form 2ⁿ × 5^m , where n and m are

non - negative integers . Then x has

a decimal expansion which terminates.

ii ) The number which is non - terminating and

non - repeating is called an

irrational number.

*******************************************

i ) x = 43.123456789

is a rational .

x = 43123456789/( 1000000000 )

= 43123456789/( 10^9 )

= 43123456789/( 2 × 5 )^9

= 43123456789/( 2^9 × 5^9 )

Here , q = 2^9 × 5^9 ( 2ⁿ × 5^m form )

43.123456789 is a terminating decimal.

ii ) 0.120120012000120000....

is non - terminating and non - repeating

decimal .

THEREFORE , it is an irrational number.

iii ) 43.123456789123456789....

is a non - terminating , repeating

decimal. So it is a rational number.

x = 43.123455789123456789....---( 1 )

10^9 x = 43123456789.123456789....--(2 )

subtracting ( 1 ) from ( 2 ) , we get

10^9 x = 43123456746

x = 43123456746/10^9

x = 43123456746/( 2 × 5 )^9

x = 43123456746/( 2^9 × 5^9 )

Therefore ,

q = 2^n × 5^m form

Given number is a rational .

I hope this helps you

48.	£510 is divided between Sarah, Gavyn & Alex so that Sarah gets twice as much as Gavyn, and Gavyn gets three times as much as Alex. How much does Gavyn get?
Answer» Given, Total money for distribution = £510 3 × Money of Alex = Gavyn's money 2× Money of Gavyn = Sarah's money For, CALCULATING the DISTRIBUTED amount of money among three of them,we have to take x (variable) as the amount of money recieved by Alex. So, Alex got = £ x Gavyn got = 3 × x = £ 3x Sarah got = 2 × 3x = £ 6x Now, the total money = (x+3x+6x) = £ 10x If we compare the value of total money given in the question,and the value of total money that we've CALCULATED,then we will get the following mathematical equation. 10x = 510 x = 51 Alex got = £ 51 Gavyn got = 3 ×51 = £ 153 Sarah got = 153 × 2 = £ 306 Hence, Alex received £51, Gavyn recieved £153 and Sarah recieved £ 306.

£510 is divided between Sarah, Gavyn & Alex so that Sarah gets twice as much as Gavyn, and Gavyn gets three times as much as Alex. How much does Gavyn get?

Answer»

Given,

Total money for distribution = £510

3 × Money of Alex = Gavyn's money

2× Money of Gavyn = Sarah's money

For, CALCULATING the DISTRIBUTED amount of money among three of them,we have to take x (variable) as the amount of money recieved by Alex.

So,

Alex got = £ x

Gavyn got = 3 × x = £ 3x

Sarah got = 2 × 3x = £ 6x

Now, the total money = (x+3x+6x) = £ 10x

If we compare the value of total money given in the question,and the value of total money that we've CALCULATED,then we will get the following mathematical equation.

10x = 510

x = 51

Alex got = £ 51

Gavyn got = 3 ×51 = £ 153

Sarah got = 153 × 2 = £ 306

Hence, Alex received £51, Gavyn recieved £153 and Sarah recieved £ 306.
