Ten years ago the father was six times as old as his daughter. After ten years, he will be twice as old as his father . Determine their present age ..
Let
10years ago
Daughter's age=xFather's age=6x10years after
Daughter's age=x+20Father's age=6x+20ATQ
[tex]\\ \tt\hookrightarrow 6x+20=2(x+20)[/tex]
[tex]\\ \tt\hookrightarrow 6x+20=2x+40[/tex]
[tex]\\ \tt\hookrightarrow 4x=20[/tex]
[tex]\\ \tt\hookrightarrow x=5[/tex]
Father's present age=6x+10=6(5)+10=30+10=40yrsDaughter's present age=x+10=5+10=15yrs▪︎If ten years ago , the age of daughter was x years , then , ten years ago the age of her father was 6x years ▪︎
Present age of father = ( 6x + 10 ) years Present age of the daughter = ( x + 10 ) yearsTen years after ,
Father's age = ( 6x + 10 + 10 ) years => ( 6x + 20 ) years Daughter's age = ( x + 10 + 10 ) years => ( x + 20 ) yearsAccording to the question,
▪︎6x + 20 = 2 ( x + 20 )
6x + 20 =! 2x + 40 6x - 2x = 40 - 40 4x = 20 x = 5Therefore , Present age of the Father = 6x + 10 = 6 × 5 + 10 = 40 years and present age of the daughter,
x + 10 = 5 + 10 = 15 yearshence , the age of his daughter is 15 years

Solution:
The rationalisation factor for [tex] \frac{1}{ a - \sqrt{b} }[/tex] is [tex]a + \sqrt{b} [/tex]
So, let us apply it here.
[tex] \frac{1}{5 - \sqrt{2} } [/tex]
The rationalising factor for 5 - √2 is 5 + √2.
Therefore, multiplying and dividing by 5 + √2, we have
[tex] = \frac{1}{5 - \sqrt{2} } \times \frac{5 + \sqrt{2} }{5 + \sqrt{2} } \\ = \frac{5 + \sqrt{2} }{(5 - \sqrt{2})(5 + \sqrt{2} ) } \\ = \frac{5 + \sqrt{2} }{ {(5)}^{2} - ( \sqrt{2})^{2} } \\ = \frac{5 + \sqrt{2} }{25 - 2} \\ = \frac{5 + \sqrt{2} }{23} [/tex]
Answer:
[tex] \frac{5 + \sqrt{2} }{23} [/tex]
Hope you could understand.
If you have any query, feel free to ask.
Answer:
[tex]\frac{5+\sqrt{2} }{23}[/tex]
Step-by-step explanation:
To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.
the conjugate of 5 - [tex]\sqrt{2}[/tex] is 5 + [tex]\sqrt{2}[/tex] , then
= [tex]\frac{1(5+\sqrt{2}) }{(5-\sqrt{2})(5+\sqrt{2}) }[/tex] ← expand denominator using aFOIL
= [tex]\frac{5+\sqrt{2} }{25-2}[/tex]
= [tex]\frac{5+\sqrt{2} }{23}[/tex]

A = 6 - 35 B = 3x + 53
Solve for x then find the measure of A.
Answer:
A = 73°
Step-by-step explanation:
A + B = 180 because of alternating interior angles
Substitute each angle
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
Substitute A
A = 6x - 35
A = 108 - 35
A = 73

a sound is sent at the bottom of a pond if echo is heard after 6 seconds calculate the depth of the pond .the speed of sound I'm water is 1498m/s
Answer:
Depth of the pond: 4494 m
Explanation:
if echo is heard after 6 seconds, it takes 3 seconds to reach to bottom of pondso time will be 3 seconds and speed given 1498 m/sSteps:
distance = speed * timedistance = 1498 * 3distance = 4494 mBrad bought a total of 9 CD's and tapes. The CD's cost $7 each and the tapes cost $6 each. He paid a total of $58. How many of each did he buy?
I ONLY NEED THE EQUATION...I can get the numbers of cans and peas I just need the equations to find the numbers
This is Algebra....please help me!!
Answer:
Step-by-step explanation:
Let the number of CD's = c
Let the number of tapes = t
Total number of CD's and tapes = 9
c + t = 9 --------------- (i)
Cost of 'c' CD's = 7*c = 7c
Cost of 't' tapes = 6*t = 6t
Total cost = $ 68
7c + 6t = 58 -----------------(ii)
Multiply the first equation by (-6) and then add the equations.
(i)* (-6) -6c - 6t = - 54
(ii) 7c + 6t = 58 {Now add. here t will be cancelled}
c = 4
Number of CD's = 4
Plugin c = 4 in equation (i)
4 + t = 9
t = 9 - 4
t = 5
Number of tapes = 5

1) A car moves with a speed of 40 km/h for 15 mins and then with a speed of 60 km/h for next 15 mins . The total distance covered by the car is : _________
(a) 100km. (b) 25km
(c) 15km. (d) 10km
• Don't spam
• Need Genuine Answer with Explanation .
Answer:
25 km
Explanation:
Distance = speed * time
We have change time which are given in minutes to hour. As the speed is mentioned in kilometre per hour.
For part A:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance = 40 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 10[/tex] km
For part B:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance =60 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 15[/tex] km
Total distance covered:
part A + part B
10 km + 15 km
25 km
25 km
Solution :-Speed of the car in first 15 mins ,
The car is moving in the speed of 40 km/h for 15 mins.
Distance covered = speed × Time taken Distance covered = 240 × 15/60 = 10 kmSpeed of car in next 15 mins ,
again ,
distance covered = 60 × 15/60 = 15kmnow , total distance covered = ( 10 + 15 ) km = 25 km
