2.	A flask contained 4 times as much water as a jug at first. After 1.05L of water were poured from the flask into jug, both containers had the same amount of water.How many litres of water are there in the jug now?
Answer» Answer: The water there in the jug now are 1,75 L. Step-by-step explanation: IMAGINE: Flask = F Jug = J F = 4J F - 1,05 = J + 1,05 Substitution: F - 1,05 = J + 1,05 4J - 1,05 = J + 1,05 4J - J = 1,05 + 1,05 3J = 2,10 J = 2,10/3 J = 0,70 L F = 4J F = 4 X 0,7 F = 2,80 L Jug now: 0,70 L + 1,05 L = 1,75 L

2.

A flask contained 4 times as much water as a jug at first. After 1.05L of water were poured from the flask into jug, both containers had the same amount of water.How many litres of water are there in the jug now?

Answer»

Answer:

The water there in the jug now are 1,75 L.

Step-by-step explanation:

IMAGINE:

Flask = F

Jug = J

F = 4J

F - 1,05 = J + 1,05

Substitution:

F - 1,05 = J + 1,05

4J - 1,05 = J + 1,05

4J - J = 1,05 + 1,05

3J = 2,10

J = 2,10/3

J = 0,70 L

F = 4J

F = 4 X 0,7

F = 2,80 L

Jug now:

0,70 L + 1,05 L = 1,75 L

7.	Solve the equation: 1+4+7+10+...+x=2871+4+7+10+...+x=287
Answer» Answer: Here, a = 1, and d = 4 - 1 = 2, S(N) = n Let n be the number of terms. We know that, S(n) = n/2[2a + (n - 1)d] Putting all the values, we get ⇒ 287 = n/2[2 × 1 + (n - 1) (3)] ⇒ 287 = n/2[2 + (n - 1)3] ⇒ 574 = 3n² - n ⇒ 3n² - n - 574 = 0 ⇒ 3n² - 42n + 41n - 574 = 0 ⇒ 3n(n - 14) + 41(n - 14) = 0 ⇒ n = 14, - 41/3 (As n can't be negative) ⇒ n = 14 We know that, a + (n - 1)d = x ⇒ 1 + (14 - 1) (3) = 3 ⇒ 1 + 13 (3) = 3 ⇒ x = 40.

7.

Solve the equation: 1+4+7+10+...+x=2871+4+7+10+...+x=287

Answer»

Answer:

Here, a = 1,

and d = 4 - 1 = 2,

S(N) = n

Let n be the number of terms.

We know that,

S(n) = n/2[2a + (n - 1)d]

Putting all the values, we get

⇒ 287 = n/2[2 × 1 + (n - 1) (3)]

⇒ 287 = n/2[2 + (n - 1)3]

⇒ 574 = 3n² - n

⇒ 3n² - n - 574 = 0

⇒ 3n² - 42n + 41n - 574 = 0

⇒ 3n(n - 14) + 41(n - 14) = 0

⇒ n = 14, - 41/3 (As n can't be negative)

⇒ n = 14

We know that,

a + (n - 1)d = x

⇒ 1 + (14 - 1) (3) = 3

⇒ 1 + 13 (3) = 3

⇒ x = 40.

given that ABC and BED are straight lines,find the values of the unknowns in each of the following figures

Answer»

Step-by-step EXPLANATION:

GIVEN: Given that ABC and BED are straight lines,FIND the values of the unknowns.

To find:a° and b°

Solution:

ABC is straight line.

$\angle \: ABE + \angle \: EBC = 180° \\ \\ \angle \: EBC = 180° - 115° \\ \\ \angle \: EBC = 65° \\ \\$

To find: a°

In ∆BCE, since angle BCE= 90°

apply angle SUM property of triangle

$\angle \: EBC + \angle \: BCE + \angle \: a = 180° \\ \\ 65° + 90° + \angle \: a = 180° \\ \\ \angle \: a = 180° - 155° \\ \\ \angle \: a = 25° \\ \\$

To find b°:

Since BED is a straight line

$\angle \: a + \angle \: FEG + \angle \: b = 180° \: \: \: ...eq1 \\ \\ (angles \: on \: straight \: line) \\ \\$

To find b, first we have to find angle FEG in ∆FEG

Apply angle sum property of triangle

$\angle \: FEG +\angle \: EFG +\angle \: FGE = 180° \\ \\ \angle \: FEG + 90° + 32° = 180° \\ \\ \angle \: FEG = 180° - 122° \\ \\ \angle \: FEG = 58° \\ \\$

Put this value to eq1

$25° +58° + \angle \: b = 180° \\ \\ \angle \: b = 180° - 83° \\ \\ \angle \: b = 97° \\ \\$

Thus,

a°= 25

b°= 97°

Hope it helps you.

Answer:

Total number of Ways = 9! * 4! if 4 particular books must always be TOGETHER. & 10! * 2 ways if 2 particular books must occupy the FIRST position and the last position.

Step-by-step explanation:

Total Books = 12

(a) 4 particular books must always be together.

Take 4 books as 1 & remaining books = 8

Total Books = 9

9 books can be ARRANGED in 9 ! ways

4 books as 1 can be arranged in 4! ways

Total number of Ways = 9! * 4!

(b) 2 particular books must occupy the first position and the last position.

2 Books can be arranged in 2! = 2 ways

Remaining 10 books can be arranged in 10! Ways

Total number of Ways = 10! * 2

32.	Find the amount and the compound intrest on Rs 10000 at 8 percent per annum and in 1 year; intrest being compounded half-yearly
Answer» Answer: Given, Principal, P =Rs.10000, Rate, R = 8% per annum compounded half yearly for 1 year. Now, There are two half years in a year. THEREFORE compounding has to be 2 TIMES. And rate = half of 10% = 5% half yearly. Therefore, the required amount = 10000(1+\frac{4}{100})^{2} = Rs. 10816 And Compound INTEREST, C.I. = Amount - Principal = Rs. (10816 - 10000) = Rs. 816.

Find the amount and the compound intrest on Rs 10000 at 8 percent per annum and in 1 year; intrest being compounded half-yearly

Answer»

Answer:

Given,

Principal, P =Rs.10000, Rate, R = 8% per annum compounded half yearly for 1 year.

Now, There are two half years in a year. THEREFORE compounding has to be 2 TIMES.

And rate = half of 10% = 5% half yearly.

Therefore, the required amount = 10000(1+\frac{4}{100})^{2} = Rs. 10816

And Compound INTEREST, C.I. = Amount - Principal = Rs. (10816 - 10000) = Rs. 816.

Given Sin A =1/3 find Cos A and Tan A

Answer»

$\bf\huge\blue{\underline{\underline{ Question : }}}$

Sin A =1/3 find Cos A and TAN A.

$\bf\huge\blue{\underline{\underline{ Solution : }}}$

★ GIVEN that,

sin A = 1/3

★ To find,

cos A
tan A

★ LET,

We know that,

$\tt\:\rightarrow \sin\:A = \cfrac{Opposite}{Hypotenuse} = \cfrac{1}{3}$

★ Now,

Opposite = 1
Hypotenuse = 3
Adjacent = ?

By using Pythagoras theorem,

$\tt\:(Hypotenuse)^{2} = (Opposite)^{2} + (Adjacent)^{2}$

$\sf\:\implies (AC)^{2} = (AB)^{2} + (BC)^{2}$

$\sf\:\implies (3)^{2} = (AB)^{2} + (1)^{2}$

$\sf\:\implies 9 = (AB)^{2} + 1$

$\sf\:\implies 9 - 1= (AB)^{2}$

$\sf\:\implies (AB)^{2} = 8$

$\sf\:\implies (AB) = \sqrt{8}$

$\sf\:\implies (AB) =2 \sqrt{2}$

★ Now,

$\sf\:\implies \cos\:A = \cfrac{Adjacent}{Hypotenuse}$

$\sf\:\implies \cos\:A = \cfrac{2\sqrt{2}}{3}$

$\sf\:\implies \tan\:A = \cfrac{Opposite}{Adjacent}$

$\sf\:\implies \tan\:A = \cfrac{1}{2\sqrt{2}}$

$\underline{\boxed{\bf{\purple{\therefore \cos\:A = \cfrac{2\sqrt{2}}{3} \: ; \: \tan\:A = \cfrac{1}{2\sqrt{2}}}}}}\:\orange{\bigstar}$
