Hey!!The wheels of a car are of diameter 80 cm each. How many complete revolutions does each wheel make in 10 minutes when the car is travelling at a speed of 66 km per hour?​

Answer»

GIVEN :

  • Diameter of a wheel of a car = 80 cm
  • The speed of the car = 66 km/HR
  • Time in which the car covers a particular distance at a speed of 66 km/hr = 10 minutes

To find :

  • Number of complete revolutions the car MAKES in 10 minutes

Concept Used :

Formula to calculate distance :-

\boxed{ \sf{ \pmb{ \blue{Distance  =  Speed \times Time}}}} \quad \star

Formula to calculate radius :-

\boxed{ \sf{ \pmb{ \blue{Radius   = \dfrac{Diameter}{2} }}}} \quad \star

Formula to calculate circumference of circle :-

\boxed{ \sf{ \pmb{ \blue{Circumference   = 2\pi r}}}} \quad \star

where,

  • Take π = 22/7
  • r = radius

Solution :

Firstly, we will calculate the distance travelled by the car in 10 minutes.

For that we will convert the time from 10 minutes into hrs first.

As we KNOW,

  • 1 min = 1/60 hr

Divide the value by 60 to convert it from minutes into hr.

→ Time = 10 min = 10/60 hr

Using formula,

\\ \dashrightarrow \quad \sf Distance  =  Speed \times Time

Substituting the given VALUES,

\\ \dashrightarrow \quad \sf Distance  =  66 \times \dfrac{10}{60}

\\ \dashrightarrow \quad \sf Distance  =   66 \times \dfrac{1 \not0}{ 6 \not0}

\\ \dashrightarrow \quad \sf Distance  =    \not66 \times \dfrac{1}{ \not6}

\\ \dashrightarrow \quad \sf Distance  =    11

\\ \dashrightarrow \quad \sf  \red{Distance  =    11 \: km}

Now,

Convert the distance covered by the car in 10 minutes from km into cm.

For that, multiply the value by 100000 cm.

→ Distance = 11 km = 11 × 100000 = 1100000 cm.

Now, Calculate the circumference of the wheel. For that firstly, find the radius.

Using formula,

\\   \dashrightarrow \quad\sf Radius   = \dfrac{Diameter}{2}

Substituting the given values,

\\   \dashrightarrow \quad\sf Radius   = \dfrac{80}{2}

\\   \dashrightarrow \quad\sf Radius   = \dfrac{ \not80}{ \not2}

\\   \dashrightarrow \quad\sf Radius   = 40

\\   \dashrightarrow \quad\sf  \red{Radius  \:  \: of \:  \: the \:  \: wheel  = 40 \: cm}

Using formula,

\\ \dashrightarrow \quad  \sf Circumference   = 2\pi r

Substituting the given values,

\\ \dashrightarrow \quad  \sf Circumference   = 2 \times  \dfrac{22}{7}  \times 40

\\ \dashrightarrow \quad  \sf Circumference   =  \dfrac{1760}{7} cm \: or \: 251.43 \: cm

Number of revolutions × Circumference = Distance travelled in 10 minutes

\\ \dashrightarrow \quad  \sf  No.  \:  \: of  \:  \: revolutions \times  \dfrac{1760}{7}  =  11

\\ \dashrightarrow \quad  \sf  No.  \:  \: of  \:  \: revolutions  =  1100000 \times  \dfrac{7}{1760}

\\ \dashrightarrow \quad  \sf  No.  \:  \: of  \:  \: revolutions  = 110000 \not0  \times  \dfrac{7}{176 \not0}

\\ \dashrightarrow \quad  \sf  No.  \:  \: of  \:  \: revolutions  = 110000  \times  \dfrac{7}{176}

\\ \dashrightarrow \quad  \sf  No.  \:  \: of  \:  \: revolutions  = 4375

\\ \star \quad  \sf   \blue{No.  \:  \: of  \:  \: revolutions   \:  \: that \:  \: the \:  \: car \:  \: makes \:  \: in \: 10 \: minutes \: = 4375}

Answer»

Answer:

HELLO mate!

Step-by-step explanation:

1st Question isn't clear

2.)The measure of each angles,

1 angle = x.

the other and the larger angle is 4 times the smaller.

so, 4x.

x° + 4x° = 90°

5x° = 90°, x= 90/5°, x= 18°

smallest Angle measures = 18°

Largest angle measures = (4×18)°= 72°

C.)Kindly, Upload the figure.

d.)The perimeter of a square= 4S = 20m

1 SIDE,/ Measure of its LENGTH = 20/4.

1 side =5m.

then, area of The square = S²= 5²= 25m².

E.)The first 7 whole Numbers, = 0, 1, 2, 3, 4, 5, 6.

hence,

The arithemtic mean= sum of Total Numbers / Total Number.

(0+1+2+3+4+5+6)/7= 21/7= 3.

F.)Mode of the Given Number Series,

4,6,8,4,10,4,6,12,6,10.

10=2; 6=3; 4=3; 8=1; 12=1;.

Mode of this series is,

6 and 4.

G.)25m² is the area of the Traingle,

traingle Area's = 1/2×Base×Height.

1/2×Base=20m× (H)m.

20Hm²/2= 25m². (20H)m²=25m²×2

20H = 50, H= 50/20. H=5/2m.

Height of the Triangle = 5/2m

H.)as it is already in ascending order,

I don't need to arrange it.

4,8,12, (16,20), 24,28,32.

Median = (16+20)/2= 36/2= 18.

Thank you mate!

Have a great day ahead!

Answer»

Answer:

p.folow me

Step-by-step explanation:

When a polynomial p(x) is divided by (x−a) , the remainder is p(a) .”

Also, when a polynomial p(x) is divided by another polynomial q(x) ,the degree of the remainder is at most 1 less than the degree of q(x) .

USING the remainder THEOREM, we can write:

p(1)=3;p(3)=5

p(x) can be written as:

Dividend=(Divisor×Quotient)+Remainder

p(x)=(x−1)(x−3)Q(x)+r(x)

r(x) is the remainder polynomial and Q(x) is the Quotient polynomial. Since r(x) is linear, r(x)=Ax+B , where A and B are ARBITRARY constants.

⟹p(x)=(x−1)(x−3)Q(x)+Ax+B

Now,

p(1)=A+B=3⟹A+B=3

p(3)=3A+B=5⟹3A+B=5

Solving the 2 EQUATIONS, we get A=1 and B=2 .

Therefore, r(x)=Ax+B=x+2

r(−2)=−2+2=0

Hence, r(−2)=0

Find the indicated terms of the sequence whose nth terms are: An = (n - 1)(2-n)(3-n); a1,a2,a3​

Answer»

ANSWER:

  1. a_{1} = 0
  2. a_{2} =0
  3. a_{<klux>3</klux>} = 0

Explanation:

GIVEN:

  • The nth term of an A.P. = a_{n} = (n - 1)(2-n)(3-n)

To find:

a1, a2 & a3​

Proof:

a_{n} = (n - 1) (2-n) (3-n)

  1. Putting n= 1 we get:

      = a_{1} = (1-1) (2-1) (3-1)

      ⇒ a_{1} = (0) (1) (2)

      ⇒ a_{1} = 0

HENCE, first term = a_{1} = 0

     2. Putting n= 2 we get:

     = a_{2} = (2-1) (2-2) (3-2)

     ⇒  a_{2} = ( 1 ) (0) (1)

     ⇒ a_{2} =0

Hence, second term = a_{2} =0

     3. Putting n= 3 we get:

     = a_{3} = ( 3-1) (2-3) (3-3)

     ⇒ a_{3} =  (2) (-1) (0)

     ⇒ a_{3} = 0

Hence, THIRD term = a_{3} = 0

  • Thus, the indicated terms of the sequence are respectively:
  1. a_{1} = 0
  2. a_{2} =0
  3. a_{3} = 0

Hope you got that.

Thank You.

If the mth term of an AP is 1/n and the nth term is 1/m,show that the sum of mn terms is 1/2(mn+1).​

Answer»

Given:-

  • mth term of an AP is 1/n.
  • the nth term is 1/m.

To prove:-

  • the sum of mn terms is 1/2(mn+1).

step-by-step SOLUTION:-

Let mth term of AP be ‘Am’ and nth term of AP be ‘An’

Therefore,

  • Am = a+ (m-1)d=1/n ----------(i)

  • An = a+(n-1)d=1/m ------------(ii)

Subtracting equation (ii) from (i)

  • d[(m - 1) - (n - 1)] = 1/n - 1/m,

  • d(m - n) = (m - n)/mn,

  • d = 1/mn --------(III)

Substituting equation (iii) in (i)

  • a + (m - 1)/mn = 1/n,

  • a = 1/n[1 - (m - 1)/m],

  • a = 1/mn --------(iv)

Now AMN i.e the mnth term of AP = a + (mn - 1)d,

Substitute equation (iii) and (iv) in Amn,

  • 1/mn + (mn - 1)/mn

  • = 1/mn[1 + (mn - 1)]

  • = mn/mn = 1,

then the mn term = 1

Sum of MN term:- :-

Amn = mn/2 ( 2/mn + (mn-1)1/mn)

  • = 1 + (mn)/2 - 1/2

  • = mn /2 + 1/2

  • = 1/2 (mn + 1)

10-if the mean of 16, 14, X, 23, 20 is 18. Find thevalue of x.a. 17b-16​

Answer»

Answer :-

  • Option a is correct.

  • The value of X is 17.

Given :-

  • The mean of 16, 14, x, 23 and 20 is 18.

To FIND :-

  • The value of x.

Step-by-step EXPLANATION :-

We know that :-

\underline{ \boxed{ \sf Mean =  \dfrac{Sum  \: of  \: observations}{Number  \: of \:  observations}}}

Here,

  • Sum of observations = 16 + 14 + x + 23 + 20.

  • Number of observations = 5.

  • Mean = 18.

-----------------

\underline{\underline{\mathfrak{Substituting  \: these  \: values \:  in  \: the \:  formula,}}}

\boxed{\sf \dfrac{16 + 14 + x + 23 + 20}{5}  = 18}

Adding all the numbers,

\implies\boxed{ \sf\dfrac{73 + x}{5}  = 18}

Transposing 5 from LHS to RHS, changing it's sign,

\implies\boxed{ \sf73 +x = 18 \times 5}

On multiplying 18 by 5,

\implies \boxed {\sf73 + x = 90}

Transposing 73 from LHS to RHS, changing it's sign,

\implies\boxed{ \sf x = 90 - 73}

Subtracting 73 from 90,

\implies \overline{\boxed{\sf x = 17.}}

-----------------------------------------------------------

  • Hence, the value of x is 17.
