18.

If 5 tanA = 4, then find the value of (5 sinA – 3 cosA)/(5 sinA + 2 cosA)

Answer»

Step-by-step explanation:

5tan = 4

tanA=4/5

p=4 b=5

h=

$\sqrt{ {5 }^{2} + {4 }^{2} }$

$\sqrt{25 + 16}$

$\sqrt{41}$

SinA=

$4 \div \sqrt{41}$

cosA=

$5 \div \sqrt{41}$

5sinA-3cosA/5sinA+2cosA

$5 \times 4 \div \sqrt{41 } - 3 \times 5 \div \sqrt{41} \div 5 \times 4 \div \sqrt{41} + 2 \times 5 \div \sqrt{41}$

$20 \div \sqrt{41} - 15 \div \sqrt{41 } \div 20 \div \sqrt{41} + 10 \div \sqrt{41}$

$5 \div \sqrt{41} \times \sqrt{41} \div 30$

Answer»

Answer:

x = 20, y = 60

Step-by-step explanation:

2x+3x+4x = 180 (ASP)

9x = 180

x = 20

ACD = 2x (AB//CD)

4x+2x+y = 180 (STRAIGHT LINE)

4*20+2*20+y = 180

80+40+y = 180

y = 180-120

y = 60

27.	A two digit number is 3 more than 4 times the sum of its digits. If 18 is added to the number, the digit is reversed. Find the fraction
Answer» Answer: Step-by-step explanation: Given :- Two digit NUMBER is 3 more than 4 times the sum of its digits. If 18 is added to the number, the digit is reversed. To Find :- The Number. Solution :- Let the TENS number be x And the units digits be y Number = (10x + y) 1st Equation. ⇒ 10x + y = 4(x + y) + 3 ⇒ 10x + y = 4x + 4y + 3 ⇒ 6x – 3y = 3 ⇒ 2x –y = 1 ……….(i) 2ND Equation. 10x + y + 18 = 10y + x ⇒ 9x – 9y = -18 ⇒ x – y = -2 ……..(ii) On SUBTRACTING (ii) from (i) x = 3 Putting x value in Eq (i) ⇒ 2x –y = 1 ⇒ 2 × 3 –y = 1 ⇒ y = 6 – 1 ⇒ y = 5 Number = (10x + y) = 10 × 3 + 5 = 30 + 5 = 35 Hence, the number is 35.

A two digit number is 3 more than 4 times the sum of its digits. If 18 is added to the number, the digit is reversed. Find the fraction

Answer»

Answer:

Step-by-step explanation:

Given :-

Two digit NUMBER is 3 more than 4 times the sum of its digits. If 18 is added to the number, the digit is reversed.

To Find :-

The Number.

Solution :-

Let the TENS number be x

And the units digits be y

Number = (10x + y)

1st Equation.

⇒ 10x + y = 4(x + y) + 3

⇒ 10x + y = 4x + 4y + 3

⇒ 6x – 3y = 3

⇒ 2x –y = 1 ……….(i)

2ND Equation.

10x + y + 18 = 10y + x

⇒ 9x – 9y = -18

⇒ x – y = -2 ……..(ii)

On SUBTRACTING (ii) from (i)

x = 3

Putting x value in Eq (i)

⇒ 2x –y = 1

⇒ 2 × 3 –y = 1

⇒ y = 6 – 1

⇒ y = 5

Number = (10x + y)

= 10 × 3 + 5

= 30 + 5

= 35

Hence, the number is 35.

43.	The jogging track at Rahul's school is mile long. Yesterday Rahul completed two laps on the track. If he ran of the distance and walked the remainder of the way, how far did he walk?
Answer» The jogging track is $\dfrac{3}{4}$ miles long, and Rahul completed two laps around the track, so to find how FAR he has completed you would multiply only the numerator of $\dfrac{3}{4}$ by 2 (because if you multiplied both the numerator and the denominator by 2, it would just be an equivalent fraction of $\dfrac{3}{4}$ ). $\dfrac{3}{4} \times \dfrac{2}{1} = \dfrac{6}{4}$ , so Rahul has completed $\dfrac{6}{4}$ miles ( $1\dfrac{1}{2}$ ). Rahul RAN $\dfrac{1}{3}$ of the distance, so divide $\dfrac{6}{4}$ by 3 to find out how much is one-third of the total distance he has completed. $\dfrac{6}{4} \div 3$ → $\dfrac{6}{4} \times \dfrac{1}{3}$ (multiplying by the reciprocal is the same thing as dividing) $\dfrac{6}{4} \times \dfrac{1}{3}$ = $\dfrac{6}{12}$ , or $\dfrac{1}{2}$ Subtract one-third of the total distance, which we just found is $\dfrac{1}{2}$ miles, from the total distance Rahul completed, $\dfrac{6}{4}$ miles. $\dfrac{6}{4} - \dfrac{1}{2}$ Multiply $\dfrac{1}{2}$ by $\dfrac{2}{2}$ to make both fractions have common DENOMINATORS. Your new subtraction PROBLEM should look like: $\dfrac{6}{4} - \dfrac{2}{4} = \dfrac{4}{4}$ , which is equivalent to 1, so this means that Rahul walked 1 mile.

The jogging track at Rahul's school is mile long. Yesterday Rahul completed two laps on the track. If he ran of the distance and walked the remainder of the way, how far did he walk?

Answer»

The jogging track is $\dfrac{3}{4}$ miles long, and Rahul completed two laps around the track, so to find how FAR he has completed you would multiply only the numerator of $\dfrac{3}{4}$ by 2 (because if you multiplied both the numerator and the denominator by 2, it would just be an equivalent fraction of $\dfrac{3}{4}$ ).

$\dfrac{3}{4} \times \dfrac{2}{1} = \dfrac{6}{4}$ , so Rahul has completed $\dfrac{6}{4}$ miles ( $1\dfrac{1}{2}$ ).

Rahul RAN $\dfrac{1}{3}$ of the distance, so divide $\dfrac{6}{4}$ by 3 to find out how much is one-third of the total distance he has completed.

$\dfrac{6}{4} \div 3$ → $\dfrac{6}{4} \times \dfrac{1}{3}$ (multiplying by the reciprocal is the same thing as dividing)

$\dfrac{6}{4} \times \dfrac{1}{3}$ = $\dfrac{6}{12}$ , or $\dfrac{1}{2}$

Subtract one-third of the total distance, which we just found is $\dfrac{1}{2}$ miles, from the total distance Rahul completed, $\dfrac{6}{4}$ miles.

$\dfrac{6}{4} - \dfrac{1}{2}$

Multiply $\dfrac{1}{2}$ by $\dfrac{2}{2}$ to make both fractions have common DENOMINATORS. Your new subtraction PROBLEM should look like:

$\dfrac{6}{4} - \dfrac{2}{4} = \dfrac{4}{4}$ , which is equivalent to 1, so this means that Rahul walked 1 mile.

If x is equal to 7 + 4 square root 3 then find the value of x square + 1 by x square

Answer»

ANSWER: 364 / 363

Step-by-step explanation:

X = 7+4√3

= 11√3

x^2+1 / x^2

=(11√3)^2 + 1 / (11√3)^2

=121*√9 +1 / 121*√9

=121*3 +1 / 121*3

=363+1 / 363

= 364 / 363

Answer» Answer: Reflection about the line SEGMENT across y axis Step-by-step EXPLANATION: SINCE we can see that the y coordinate remains the same after reflection and the x coordinate reverse it SIGN after reflection , it should be the reflection about the y axis Reflection about y axis= before (x,y) after (-x,y) about x axis = before (x,y) after(x,-y) about y=x = before(x,y) after (y,x) about y=-x before(x,y) after(-y,-x)

Answer»

Answer:

Reflection about the line SEGMENT across y axis

Step-by-step EXPLANATION:

SINCE we can see that the y coordinate remains the same after reflection and the x coordinate reverse it SIGN after reflection , it should be the reflection about the y axis

Reflection about y axis= before (x,y) after (-x,y)

about x axis = before (x,y) after(x,-y)

about y=x = before(x,y) after (y,x)

about y=-x before(x,y) after(-y,-x)
