1.	Find the sum of odd numbers between 0 to 50 in AP
Answer» Answer: 625 Step-by-step explanation: sum = 1 + 3 + 5 + 7 + ......+49. this is an A.P, whose first term(a) = 1 and last term(TN) = 49. common difference(d) = 3-1 = 2 Total no. of odd number lie b/w 0 and 50 = n but, Tn = a + (n-1)d or, 49 = 1 + (n-1)2 or, n-1 = 48/2 =24 n = 25 hence sum = n/2(a + Tn) sum = 25(1 + 49)/2 sum = 25×50/2 = 25×25 sum = 625

1.

Find the sum of odd numbers between 0 to 50 in AP

Answer»

Answer:

625

Step-by-step explanation:

sum = 1 + 3 + 5 + 7 + ......+49.

this is an A.P, whose first term(a) = 1 and last term(TN) = 49.

common difference(d) = 3-1 = 2

Total no. of odd number lie b/w 0 and 50 = n

but,

Tn = a + (n-1)d

or, 49 = 1 + (n-1)2

or, n-1 = 48/2 =24

n = 25

hence

sum = n/2(a + Tn)

sum = 25(1 + 49)/2

sum = 25×50/2 = 25×25

sum = 625

Form a solid hemisphere a radius r, a sphere of maximum diameter is cut out. The volume of sphere is?

Answer»

A SPHERE ⚾ with maximum VOLUME can be cut from a solid hemisphere will be ONE whose

Diameter is equal to the the RADIUS of the hemisphere

let r be the radius of hemisphere

Then radius of sphere = r / 2

volume of hemisphere. = 2 / 3π r^3

volume of sphere = 4 / 3π (r/2) ^ 3

RATIO = VOL.OF HEMI,SPH / VOL,OF, SPH

= 2/3πr^3. / 4/3π((r/2))^3

= 4

Therefore. ratio = 4 : 1

Hope it helps!!

Answer»

32

Step-by-step explanation:

Given:

$\sqrt[5]{27 {}^{(x - 2)} } = \sqrt[3] { {9}^{(x - 5)} }$

To find:

The value of x

Solution:

#TABII ki SIZE yardımcı olacağım :)

This question is related to Laws of Indices.

So, We solve it by using the rules.

1st_Make the base exponent in smaller FORM i.e 25 = 5², 27 = 3³

2nd_ Splitting the variable and constant powers

i.e

${5}^{(x + 2)} = {5}^{x} . {5}^{2}$

Now,

$\sqrt[5]{27 {}^{(x - 2)} } = \sqrt[3] { {9}^{(x - 5)} } \\ \\ \sqrt[5]{ {3}^{3(x - 2)} } = \sqrt[3]{ {3}^{2(x - 5)} } \\ \\ \sqrt[5]{ {3}^{(3x - 6)} } = \sqrt[3]{ {3}^{(2x - 10)} } \\ \\ { 3}^{ \{(3x - 6). \frac{1}{5} \} } ={ 3}^{ \{(2x - 10). \frac{1}{3} \} } \\ \\ {3}^{ \frac{3x}{5} } . {3}^{ \frac{ - 6}{5} } = {3}^{ \frac{2x}{3} } . {3}^{ \frac{ - 10}{3} } \\ \\ \frac{ {3}^{ \frac{ - 6}{5} } }{ {3}^{ \frac{ - 10}{3} } } = \frac{ {3}^{ \frac{2x}{3} } }{ {3}^{ \frac{3x}{5} } } \\ \\ {3}^{( \frac{ - 6}{5} + \frac{ 10}{3}) } = {3}^{( \frac{2x}{3} - \frac{3x}{5}) } \\ \\ {3}^{ (\frac{ - 6.3 + 10.5}{15} )} = 3 {}^{( \frac{5.2x - 3x.3}{15}) } \\ \\ [\text{Eliminating the base from both sides}] \\ \\ \frac{ - 18 + 50}{15} = \frac{10x - 9x}{15} \\ \\ \frac{ 32}{\cancel{15}} = \frac{x}{ \cancel{15}} \\ \\ x = 32$

Therefore, the required answer is 32.

${\underline{\blue{\text{ Some Important Laws of Indices}}}}$

${a}^{n}.{a}^{m}={a}^{(n + m)}$

${a}^{-1}=\dfrac{1}{a}$

$\dfrac{{a}^{n}}{ {a}^{m}}={a}^{(n-m)}$

${({a}^{c})}^{b}={a}^{b\times c}={a}^{bc}$

${a}^{\frac{1}{x}}=\sqrt[x]{a}$

[Where all variables are real and GREATER than 0]

Answer» Answer: 5 books must be read in 1 month for the total charges from each club to be equal. Step-by-step explanation: Monthly Charges of ABC club = 40$ PER book read charges of ABC club = 2$ amount of book read = x Total charges of ABC club = 40 + 2x Monthly Charges of Easy book club = 40$ Per book read charges of Easy Book club = 3$ Total charges of Easy book club = 35 + 3x To calculate how MANY books must be read in 1 month for the total charges from each club to be equal, Total charges of ABC club = Total charges of Easy book club 40 + 2x = 35 + 3x 40 - 35 = 3x -2x 5 = x x = 5 Therefore, 5 books must be read in 1 month for the total charges from each club to be equal.

The ABC Book Club charges a $40 monthly fee, plus $2 per book read in that month. The Easy Book Club charges a $35 monthly fee, plus $3 per book read in that month. For each club, how many books must be read in 1 month for the total charges from each club to be equal?

Answer»

Answer:

5 books must be read in 1 month for the total charges from each club to be equal.

Step-by-step explanation:

Monthly Charges of ABC club = 40$

PER book read charges of ABC club = 2$

amount of book read = x

Total charges of ABC club = 40 + 2x

Monthly Charges of Easy book club = 40$

Per book read charges of Easy Book club = 3$

Total charges of Easy book club = 35 + 3x

To calculate how MANY books must be read in 1 month for the total charges from each club to be equal,

Total charges of ABC club = Total charges of Easy book club

40 + 2x = 35 + 3x

40 - 35 = 3x -2x

5 = x

x = 5

Therefore, 5 books must be read in 1 month for the total charges from each club to be equal.

45.

A driver applies brakes and slows down the velocity of the car from 50km per hour to 30 km per hour in 5 seconds. Calculate the acceleration

Answer»

Answer:

Step-by-step EXPLANATION:

INITIAL VELOCITY , U = 50 KM/H

FINAL VELOCITY ,V = 30 KM/H

TIME TAKEN ,T = 5 SEC

= 5/60*60

= 5/3600

= 0.0013 HRS

ACCORDING TO NEWTON'S FIRST LAWS OF MOTION:

V = U + A T

30 = 50+A*0.0013

-20 = A*0.0013

A = -20/0.0013

A = - 15,384.6 KM/H

DECELERATION = 15,384.6 KM /H².

HOPE THIS HELPS.
