Answer»

Correct Question :

  • The distance between the school and the students house is 1km 875m. EVERY day she WALKS both WAYS. FIND the total distance covered by her in six days.

GIVEN :

  • The distance between the school and the students house is 1km 875m. Every day she walks both ways.

TO FIND :

  • find the total distance covered by her in six days.

SOLUTION :

Distance between school and house :

➨ 1km + 875 m.

➨ 1000 m + 875 m (1 km = 1000 m)

➨ 1875 m

Distance covered each day :

➨ 1875 × 2

➨ 3750 m

Distance covered in 6 days :

➨ 3750 × 6

➨ 22500 m

Therefore, total distance covered in 6 days is 22,500 m.

Converting in kilometer :

➨ 1000 m = 1 km

➨ 1 m = 1/1000 km

➨ 22500 m = 22500/1000 km

➨ 22500 m = 22 km 500 m

Hence, the total distance is 22 km 500 m.

Each ofof the following usingEvaluteidentities :-991 x 982​

Answer»

Answer:

973162

Step-by-step explanation:

991 × 982 = (1000-9)(1000-18)

Using the IDENTITY (x+a)(x+b) = x²+(a+b)x+ab

Here x=1000, a=(-9), b=(-18)

(1000-9)(1000-18)= (1000)²+[-9+(-18)]1000+[(-9)(-18)]

                            = 1000000+(-27)1000+162

                            = 1000000+(-27000)+162

                            = 1000000-27000+162

                            = 973000+162

                            = 973162

Two supplimentry angles are such that one is two-third of another. find them

Answer»

Let x and y be the TWO ANGLES

They are supplement MEANS x+y=180

Now one angle is two third of another which

means x=2y/3

PUTTING in to equation

2y/3 +y=180

2y+3y/3=180

⇒5y=180×3

⇒y= 180×3/5

⇒y=108

y=108

x= 2y/3

=

2⋅108/3

=72

∴x=72 and y=108.

Answer»

Answer:

Step-by-step explanation:

1 APPLE for RUPEES 2.75

So 34 apples COST = 2.75×34

= 93.5 rupees

Now the increased cost

1 apple cost = 2.75 + .99

= 3.74 rupee

So now

3.74 rupees for 1 apple

1 rupee for 1/3.74

93.5 rupees = 1/3.74×93.5

= 25 apples (approx)

Show that each of the following numbers is a perfect square . in each case , find the number whose square is the given number1 12252 59263 8281​

Answer»

Step-by-step explanation:

A perfect square can always be expressed as a product of equal FACTORS.

(i)

Resolving into prime factors:

441=49×9=7×7×3×3=7×3×7×3=21×21=(21)2

Thus, 441 is a perfect square.

(II)

Resolving into prime factors:

576=64×9=8×8×3×3=2×2×2×2×2×2×3×3=24×24=(24)2

Thus, 576 is a perfect square.

(iii)

Resolving into prime factors:

11025=441×25=49×9×5×5=7×7×3×3×5×5=7×5×3×7×5×3=105×105=(105)2

Thus, 11025 is a perfect square.

(iv)

Resolving into prime factors:

1176=7×168=7×21×8=7×7×3×2×2×2

1176 cannot be expressed as a product of two equal NUMBERS. Thus, 1176 is not a perfect square.

(v)

Resolving into prime factors:

5625=225×25=9×25×25=3×3×5×5×5×5=3×5×5×3×5×5=75×75=(75)2

Thus, 5625 is a perfect square.

(vi)

Resolving into prime factors:

9075=25×363=5×5×3×11×11=55×55×3

9075 is not a product of two equal numbers. Thus, 9075 is not a perfect square.

(vii)

Resolving into prime factors:

4225=25×169=5×5×13×13=5×13×5×13=65×65=(65)2

Thus, 4225 is a perfect square.

(viii)

Resolving into prime factors:

1089=9×121=3×3×11×11=3×11×3×11=33×33=(33)

Answer:

The ANS. would be 25

Step-by-step explanation:

Vaibhav has MONEY to buy 34 APPLES at the rate 2.75

First FIND the money that have vaibhav so,

The money that have Vaibhav is 34×2.75=93.75

If the rate increase.99p the rate of per apple would be 2.75+.99 =3.74

So the money that have Vaibhav is 93.50

The rate of per apple = 3.74

Vaibhav buy apple =93.75/3.74=25

25 apple.

In right triangle ABC, right angled at C, M is the mid-point of hypotenuse AB. C is joined to M and produced to a point D such that DM = CM. Point D is joined to point B.Show that: (i) ΔAMC ≅ ΔBMD (ii) ∠DBC is a right angle. (iii) ΔDBC ≅ ΔACB (iv) CM = 1/2AB Please give me the answer,urgently needed

Answer»

Solution:-

(i) In ΔAMC and ΔBMD,

AM = BM (M is the mid-point of AB)

∠AMC = ∠BMD (Vertically opposite angles)

CM = DM (Given)

∴ ΔAMC ≅ ΔBMD (By SAS congruence RULE)

AC = BD (By CPCT)

And, ∠ACM = ∠BDM (By CPCT)

(ii) ∠ACM = ∠BDM

However, ∠ACM and ∠BDM are alternate interior angles.

Since alternate angles are equal,

It can be said that DB || AC

\Rightarrow ∠DBC + ∠ACB = 180º (Co-interior angles)

\Rightarrow ∠DBC + 90º = 180º

\Rightarrow ∠DBC = 90º

iii) In ΔDBC and ΔACB,

DB = AC (Already proved)

∠DBC = ∠ACB (Each 90)

BC = CB (Common)

∴ ΔDBC ≅ ΔACB (SAS congruence rule)

(iv) ΔDBC ≅ ΔACB

∴ AB = DC (By CPCT)

\Rightarrow AB = 2 CM

\sf{}  \because CM =\dfrac{1}{2}AB
