1.	consider a proper fraction such that the numerator is 2 less than the denominator. if the numerator and denominator are each increased by 1, then the ratio of the numerator and denominator of the new fraction is 4:5. determine the original fraction
Answer» Answer:- LET the fraction be x/y. Given: Numerator is 2 less than the denominator. ⟶ Numerator = denominator - 2 ⟶ x = y - 2 -- equation (1) And, If numerator and denominator are increased by 1 , the RATIO of numerator and denominator is 4 : 5. According to the above condition, $\longrightarrow \sf \: \dfrac{x + 1}{y + 1} = \dfrac{4}{5}$ Substitute the VALUE of x from equation (1). $\longrightarrow \sf \: \frac{y - 2 + 1}{y + 1} = \frac{4}{5} \\ \\ \longrightarrow \sf \:5(y - 1) = 4(y + 1) \\ \\ \longrightarrow \sf \:5y - 5 = 4y + 4 \\ \\ \longrightarrow \sf \:5y - 4y = 4 + 5 \\ \\ \longrightarrow \boxed{ \sf \:y = 9}$ Substitute the value of y in equation (1) ⟶ x = y - 2 ⟶ x = 9 - 2 ⟶ x = 7 ∴ The original fraction x/y is 7/9

consider a proper fraction such that the numerator is 2 less than the denominator. if the numerator and denominator are each increased by 1, then the ratio of the numerator and denominator of the new fraction is 4:5. determine the original fraction

Answer»

Answer:-

LET the fraction be x/y.

Given:

Numerator is 2 less than the denominator.

⟶ Numerator = denominator - 2

⟶ x = y - 2 -- equation (1)

And,

If numerator and denominator are increased by 1 , the RATIO of numerator and denominator is 4 : 5.

According to the above condition,

$\longrightarrow \sf \: \dfrac{x + 1}{y + 1} = \dfrac{4}{5}$

Substitute the VALUE of x from equation (1).

$\longrightarrow \sf \: \frac{y - 2 + 1}{y + 1} = \frac{4}{5} \\ \\ \longrightarrow \sf \:5(y - 1) = 4(y + 1) \\ \\ \longrightarrow \sf \:5y - 5 = 4y + 4 \\ \\ \longrightarrow \sf \:5y - 4y = 4 + 5 \\ \\ \longrightarrow \boxed{ \sf \:y = 9}$

Substitute the value of y in equation (1)

⟶ x = y - 2

⟶ x = 9 - 2

⟶ x = 7

∴ The original fraction x/y is 7/9

Answer»

Answer:

in RHOMBUS,

opposite ANGLES are equal

therefore,

angleH=angleM

angleH=120°

angleM=3w-30

3w-30=120°

3w= 120-30

3w=90

w=90/3

w=30°

option B)=30° is the CORRECT ANSWER

Step-by-step explanation:

I can't FIND the symbol of ANGLE so instead of using symbol I WROTE ANGLE

13.

1. If sine725find the values of coso and tano.

Answer»

Answer:

CORRECT Question:

If SinA = 7/25 , FIND Values of COSA & TanA

Solution:

$: { \implies{ \sf{SinA = \frac{7}{25} = \frac{opp}{hyp} }}} \\$

For finding CosA and TanA, We have to find ADJACENT Side by using Pythagoras theorm.

$\boxed{ \sf{Pythagoras \: theorm : Hyp² = Opp² + Adj² }}$

$:{ \implies{ \sf{Hyp² = Adj² + Opp²}}} \\ \\ : { \implies{ \sf{ {25}^{2} =Adj² + {7}^{2} }}} \\ \\ : { \implies{ \sf{ {25}^{2} - {7}^{2} = Adj²}}} \\ \\ : { \implies{ \sf{Adj² = 625 - 49}}} \\ \\ : { \implies{ \sf{Adj² = 576}}} \\ \\ : { \implies{ \sf{Adjacent \: side = 24cm}}}$

So, Adjacent Side = 24 Cm

$\to{ \sf{CosA = \frac{adjacent} {hypotenuse} = \frac{24}{25} }} \\$

$\to{ \sf{TanA = \frac{opposite}{adjacent} = \frac{7}{24} }} \\$

Answer» Answer: Given: MEAN of numbers is 8 The numbers are:7,9,x,13,6 To calculate mean we have FORMULATION, =(Sum of total numbers)/(COUNT of total given numbers) So the Mean is given that is 8 therefore, 8=(7+9+x+13+6)/(5) 8*5=35+x 40=35+x X=40–35 [X=5] The value of X is 5.

The mean of 8, 13, 6, 4, x ,7 ,9 ,16, 12 is (x + 3). Find the value of mean and median.

Answer»

Answer:

Given: MEAN of numbers is 8

The numbers are:7,9,x,13,6

To calculate mean we have FORMULATION,

=(Sum of total numbers)/(COUNT of total given numbers)

So the Mean is given that is 8 therefore,

8=(7+9+x+13+6)/(5)

8*5=35+x

40=35+x

X=40–35

[X=5]

The value of X is 5.

47.	Check wheather 101 is term of ap 12,15, 18
Answer» Solution - We have, A.P = 12, 15, 18, ... ⠀ Here, FIRST TERM (a) = 12 Common difference (d) = 3 ⠀ Now, we have to check whether 101 is a term of the GIVEN A.P. or not. For this, we let aₙ = 101 ⠀ We know that, ⠀ ⠀⠀⠀⠀★ aₙ = a + (n - 1)d ⠀ ➝ aₙ = 101 ➝ a + (n - 1)d = 101 ➝ 12 + (n - 1) × 3 = 101 ➝ (n - 1)3 = 101 - 12 ➝ (n - 1)3 = 99 ➝ n - 1 = 99/3 ➝ n - 1 = 33 ➝ n = 33 + 1 ➝ n = 34 ⠀ Therefore, 34th term of the given A.P. is 101. Hence, 101 is a term of A.P.

47.

Check wheather 101 is term of ap 12,15, 18

Answer»

Solution -

We have,

A.P = 12, 15, 18, ...

⠀

Here,

FIRST TERM (a) = 12
Common difference (d) = 3

⠀

Now, we have to check whether 101 is a term of the GIVEN A.P. or not. For this, we let

aₙ = 101

⠀

We know that,

⠀ ⠀⠀⠀⠀★ aₙ = a + (n - 1)d

⠀

➝ aₙ = 101

➝ a + (n - 1)d = 101

➝ 12 + (n - 1) × 3 = 101

➝ (n - 1)3 = 101 - 12

➝ (n - 1)3 = 99

➝ n - 1 = 99/3

➝ n - 1 = 33

➝ n = 33 + 1

➝ n = 34

⠀

Therefore, 34th term of the given A.P. is 101.

Hence, 101 is a term of A.P.
