14.

Hari has 5 1/2 of milk. he use 4/5 of the total milk and gives 1/3 of remaining to his friend. A) How much milk did he use?. B)how much milk was left with?

Answer»

Step-by-step EXPLANATION :

no of litres of milk hari had = 5 1/2 = 11/2

he used = 4/5

hence 11 / 2 - 4/5

take lcm for 2 & 5, is 10

55 - 8 / 10 = 47 / 10

the milk left with him after his usage = 47 / 10

he gave 1/3 of milk to his friend = 47/10 - 1/3

now lcm for 10 & 3, is 30

141 - 10 / 30 = 131 / 30

Answer» $\star\green\boxed{\bf ANSWER}}\star$ Given : Series : 11, 9, 7, 5, 3, 1 To Find : Tenth term of the series. Solution : Given series is in ARITHMETIC progression (AP) AP : 11, 9, 7, 5, 3, 1 Here, First term, a = 11 common DIFFERENCE, d = 9 - 11 = -2 n = 10 Let, tenth term be a10. nth term of an AP, an = a + (n - 1)d $\implies$ a10 = 11 + (10 - 1)-2 $\implies$ a10 = 11 - 18 $\implies$ a10 = -7 Therefore, 10th term = -7.

23.

What is the tenth term of 11 9 7 5 3 1

Answer»

$\star\green\boxed{\bf ANSWER}}\star$

Given :

Series : 11, 9, 7, 5, 3, 1

To Find :

Tenth term of the series.

Solution :

Given series is in ARITHMETIC progression (AP)

AP : 11, 9, 7, 5, 3, 1

Here,

First term, a = 11

common DIFFERENCE, d = 9 - 11 = -2

n = 10

Let, tenth term be a10.

nth term of an AP, an = a + (n - 1)d

$\implies$ a10 = 11 + (10 - 1)-2

$\implies$ a10 = 11 - 18

$\implies$ a10 = -7

Therefore, 10th term = -7.

Step-by-step EXPLANATION:

Let

$y = \sqrt{6 + \sqrt{6 + \sqrt{6 + ...... + \infty } } }$

$= > y = \sqrt{6 + y}$

$= > {y}^{2} = 6 + y$

$= > {y}^{2} - y - 6 = 0$

$= > {y}^{2} - 3y + 2y - 6 = 0$

$= > y(y - 3) + 2(y - 3) = 0$

$= > (y - 3)(y + 2) = 0$

$either \: \: y = 3 \: \: or \: \: y = - 2$

since, SQUARE ROOT is a POSITIVE QUANTITY,

so we have y=3

In figure 2.6, line p || line q andline 1 and line m are transversals.Measures of some angles are shown.Hence find the measures ofa, b, e, d.

Answer»

Answer:

Given line P ∥ line Q and line L and M are transversal.

To find: ∠ a, ∠ b, ∠ c∠ d.

Construction: extend G and E in answer diagram.

∠ a + ∠ e = 180° (linear pair angle) means that linear pair is a pair of adjacent, supplementary angle.

Adjacent means NEXT to each other, and supplementary means that measures of the TWO angles add up to equal 180°.

∠ a + 110° = 180° (given)

∠ a = 70°

∠ a ≅ ∠ g (vertically opposite angles formed are congruent

∠ a = 70° (prove above)

∠ 70° ≅ ∠ g

Line P || line Q and line L transversals (given)

∠ g = ∠ b (corresponding angles)

∠ b = 70°

Line P || line Q and line M is transversal (given)

∠ c ≅ ∠ F (corresponding angles) if two parallel line are CUT by a transversal, then the pairs of corresponding angle are congruent.

So, ∠ f = 115° (given)

Then, ∠ c = 115°

∠ d + ∠ f = 180° (linear pair angle)

∠ d + 115° = 180° (given)

∠ d = 180° -115°

∠ d = 65°

Given line P ∥ line Q and line L and M are transversal.

To find: ∠ a, ∠ b, ∠ c∠ d.

Construction: extend G and E in answer diagram.

∠ a + ∠ e = 180° (linear pair angle) means that linear pair is a pair of adjacent, supplementary angle.

Adjacent means NEXT to each other, and supplementary means that measures of the TWO angles add up to equal 180°.

∠ a + 110° = 180° (given)

∠ a = 70°

∠ a ≅ ∠ g (vertically opposite angles formed are congruent

∠ a = 70° (prove above)

∠ 70° ≅ ∠ g

Line P || line Q and line L transversals (given)

∠ g = ∠ b (corresponding angles)

∠ b = 70°

Line P || line Q and line M is transversal (given)

∠ c ≅ ∠ F (corresponding angles) if two parallel line are CUT by a transversal, then the pairs of corresponding angle are congruent.

So, ∠ f = 115° (given)

Then, ∠ c = 115°

∠ d + ∠ f = 180° (linear pair angle)

∠ d + 115° = 180° (given)

∠ d = 180° -115°

∠ d = 65°
