A cirlce containing 360 degrees it would do this twice 2 x 360 would be 720 degrees. Please explain to me how it would only traverse 45 degrees I really dont see how that is correct.

>> micxj: let:
x=father's age at present
y= son's age at present
two times the father's age is '8 more than 6 times his son's age' would be represented by this equation:
2x=8+6y
'Ten years ago, the sum of their ages was 44':
(x-10)+(y-10)= 44
x+y-20=44
x+y=44+20
x+y=64
yung age ng son ang tinatanong so, we need to find the value of x in order to get the value of y (son's age)
if,
2x=8+6y
then,
x=4+3y
since x+y=64 and x=4+3y:
x+y=64
(4+3y)+y=64
4y+4=64
4y=64-4
4y=60
y=60/4
y=15
so the son's age is 15
Two times the father's age is 8 more than six time |
>> micxj: let:
x=man's age at present
y=son's age at present
x=41
x+7=48
48=4(y+7)
48=4y+28
48-28=4y
20=4y
y=5

if the angle would be more than 360 degrees in a circle then that wouldn't be referred to as rotation anymore right?, it's revolution. in two hours, the minute hand does two revolutions thus covering an angle of 720 degrees, but i don't think that's the answer were looking for

let the two nos be represented by x and y.
xy=1400
x=1400/y
y=1400/x
(x-3)(y-3)=1175
xy-3y-3x+9=1175
(i used y. since y=1400/x; and xy=1400.....)
xy-3y-3x+9=1175
1400-3(1400/x)-3x=1175-9
1400-3(1400/x)-3x=1166
-3(1400/x)-3x=1166-1400
-3(1400/x)-3x=-234
(1400/x)+x=78
1400/x=78-x
78x-x^2=1400
-x^2+78-1400=0
or
x^2-78x+1400=0
(x-50)(x-28)=0
x=50;x=28

>> micxj: i was confident that the correct answer must be 36.
uhm,. here's my solution, please tell me if there's an error here:
let the ten's digit be 'x'
and the unit's digit be 'y'
the number would be (10x+y)
'the unit's digit is 3 greater than the ten's digit'
y=x+3
'the number is 4 times as large as the sum of its digits'
10x+y=4(x+y)
if,
y=x+3 and 10x+y=4(x+y)
then,
10x+x+3=4(x+x+3)
11x+3=4(2x+3)
11x+3=8x+12
11x-8x=12-3
3x=9
x=3
y=x+3
y=3+3
y=6
no.=xy
x=3
y=6
no.=36
so the correct ans would be 36 right?

>> micxj: suppose that the population mentioned there was the population in the year 2007.
on 2008(the 1st year), the population would be 105% of the population during 2007
on 2009(2nd yr), it'll be 110.25%(1.1025) because
1.05+(1.05x.05)=1.1025
on the 3rd year:
1.1025+(1.1025x.05)=1.157625
the asked value is the percentage it will increase after three years.
after three year, the population would be 115.7625% or 1.1576% of the original population
115.76%-100%=15.76%
The population of the country increases 5% each ye |
>> micxj: correction:(i omitted the % sign after 1.1576)
the asked value is the percentage it will increase after three years.
after three year, the population would be 115.7625% or 1.1576 of the original population
115.76%-100%=15.76%
The population of the country increases 5% each ye |
>> micxj: or:
the problem follows the growth formula N(subscript t=P(1+r)^t
where t=time
P=original value
r=rate of increase
t= 3 years
r=5% or .05
P(1+.05)^3
P(1.05)^3
P(1.157625)
1+r=1.157625
r=1.157625-1
r=.157625 or 15.76%

>> Guest: bez, it's jacky. let x be the rate of Oscar. y be the rate of james.
if they are to meet after 32 seconds of running in opposite direction, that mins that the sum of the distances they've covered is equal to the circumference of the track. try to imagine it..
so, the working equation would be 32x + 32y =440.
rate=distance/time.
thus, the r of Oscar is 440/60. that is 22/3.
so, we now have,
32(22/3) + 32y = 440
we multiply the equation ol thruout by 3 for simplification.
so, we now have,
704+96y=1320
y=6.4166.. seconds
that is the r of James. but wat is asked hir is the time it will take james to go around the track.
so,the formula is t=d/r
ryt?
t=440/6.4166..
that's around 68. 57 seconds..
got it? :)

algebraically,
n+n=2n
where

"two of the boys are replaced by two other girls"

>> Guest: Here is my solution.
Kindly verify.
x = amount of time needed by Peter to finish a job
y = amount of time needed by Paul to finish a job
3 = amount of time needed by Peter and Paul working together to finish a job.
this means that in an hour,
1/x = amount of work finished by Peter
also,
8/x = amount of work finished by peter in 8 hours
and in an hour,
1/y = amount of work finished by Paul
and in an hour,
1/3 = amount of work finished by Peter and Paul working together
"Peter and Paul can do a certain job in 3 hours."
(1/x)+(1/y) = 1/3
"They worked together for 1 hour" means
(1/x)+(1/y)
"they worked together for 1 hour then Paul left and Peter finishes the rest of the work in 8 more hours."
(1/x)+(1/y)+(8/x)=1
our two equations would be
(1/x)+(1/y)=1/3
(1/x)+(1/y)+(8/x)=1
substitution, we have
y=4
x=12
Kindly validate my formula.

by substitution method
(eq.1 to eq.2)
3y = 3 + 2(11-y)
3y = 3 + 22 - 2y
3y+2y = 25
5y = 25
5y/5 = 25/5
y = 5
substitute the y value to eq.1
x = 11 - y
x = 11 - 5
x = 6
since, y=5 and x=6 then the numbers must be the reciprocal of the value solved...
therefore: the numbers are 1/6 & 1/5
The sum of the reciprocals of two numbers is 11. |

1/b+ 1/c = 1/31
1/a + 1/c= 1/20

1/2a+1/2b+1/2c= 1/42+1/31+1/20

other number is 5 less than the other so it is "x-5"
according to the question the sum of the two number is 135

2x=140
2x/2=140/2

>> dhax12: Min hand over takes hr hand after the 15min mark w/c is after 3o'clock
let x be the total time from 3o'clock to point the min hand over takes hr hand.
in eqn form:
x=(x/12)+15
x/12 is the length of time the min hand over takes hr hand.
solve for x
x-(x/12)=15
(12x-x)/12=15
11x/12=15
x=(15)(12)/11
x=180/11=16 4/11
this proves 14/12 is wrong.

How many minutes after 3:00PM will the minute hand |
>> dhax12: Solution is:
in 1hr=60 min,
therefore,
2hrs=120min
convert 120min to degrees
180 degrees=30min
120min x (180 degrees/30min)
=720 degrees
therefore, the contributor shall go back to nursery. LOL

>> dhax12: Tama na answer oi!
Let r be the rate of copier,
r=no. of copies/time
given no. of copies=13 and time=10sec
then, r=13/10=1.3 copies per second
now naa kta rate=1.3 copies/second, hanap ta no. of copies in 1hr.
1hr=3600sec.
no. of copies=rate x time
time=1 hr=3600 sec.
no. of copies=1.3 x 3600
no. of copies=4680 copies
A certain copier produces 13 copies every 10 secon |
>> dhax12: Mr. Rice can finish the wash in 15 min, his son paul takes twice as long doing the same wash that is 15 x 2 = 30min.
one hint here is take the rate of each in one job and add their individual rate.
Let x be the time to finish the wash.
For mr. Rice his rate is 1/15, 1 indicates that that he can do 15 min to finish a "single" wash w/c is 1.
For paul it is 1/30,
the equation shall be,
(1/15)x+(1/30)x=1
why equals to 1?
It is said that they can finish washing (single job) if they work together.
Solve for x,
that will give you,
x=10 min.
