Is 14 a factor of 42 and 112? is 14 a factor of (112+42) and (112-43)​

Answer»

14 is a factor of (112+42) but it is not a factor of (112-43)

Find the probablity of getting 52 sundays in a leap year no silly answersfast pls

Answer»

There are 365 days in a year but we have 366 days in a leap year.

There are 365 days in a year but we have 366 days in a leap year.There are 7 days in a week.

There are 365 days in a year but we have 366 days in a leap year.There are 7 days in a week.If we multiply the weeks by the days we have 52x7 which equals to 364. This means that there are 2 extra days in a leap year which will make it 366.

There are 365 days in a year but we have 366 days in a leap year.There are 7 days in a week.If we multiply the weeks by the days we have 52x7 which equals to 364. This means that there are 2 extra days in a leap year which will make it 366.The probability of having 52 SUNDAYS in a leap year is thus: the remaining two days can be any of this formation:

This means that there are 2 extra days in a leap year which will make it 366.The probability of having 52 Sundays in a leap year is thus: the remaining two days can be any of this formation:Sunday-Monday, Monday-Tuesday, Tuesday-Wednesday, Wednesday-Thursday, Thursday-Friday, Friday-Saturday, Saturday-Sunday.

Therefore, out of the 7 COMBINATIONS above, that can be only realized 5 out of 7 times. The connection "Sunday-Monday and Saturday-Sunday" most be scraped off.

Two men, Ralph and Sean, take up a typing job requiring 100 pages to be typed. Each of them types 50pages. Sean charges $20 per hour while Ralph (being 1.5 times as fast as Sean) charges $30 per hour. Whatis the average hourly wage they earn?​

Answer»

Answer:

average hourly wage they earn = 24 $

Step-by-step explanation:

Two men, Ralph and Sean, take up a typing JOB requiring 100 pages to be TYPED. Each of them types 50

pages. Sean charges $20 PER hour while Ralph (being 1.5 times as fast as Sean) charges $30 per hour

Let say Sean  speed X pages per hr

Sean type 50 pages

NUMBER of hrs taken = 50/X  hr

Charges = 20 * 50/X  = 1000/X   $

Ralph speed  1.5X  pages per hr

Ralph type 50 pages

Number of hrs taken = 50/(1.5X)  =  100/3X hr

Charges = 30 * 50/(1.5X)X  = 1000/X  $

Total Charges = 1000/X  + 1000/X   = 2000/X  $

Total Hrs = 50/X   + 100/3X  = (150 + 100)/3X  = 250/3X

average hourly wage = Total Charges /Total Hrs

= (2000/X)/(250/3X)

= 24

average hourly wage they earn = 24 $

Let A and B be two fixed points, find the locus of the point for which angleAPB is a right angled.

Answer»

SOLUTION

Let AB= 2a and P(X,y) be a VARIABLE point

A=A(-a,0), B=(a,0)

Given, Angle 90°

Then,

AP^2 +PB^2 = AB^2

=  > (x + a) {}^{2}  +  {y}^{2}  + (x - a) {}^{2}  +  {y}^{2}  = (2a) {}^{2}  \\  =  > 2 {x}^{2}  + 2 {y}^{2}  + 2 {a}^{2}  = 4 {a}^{2} \\  =  >  {x}^{2}  +  {y}^{2}  =  {a}^{2}

Answer»

INCOMPLETE QUESTION MATE.......^_^

50.

A and B are the two points (3,4) and (5,-2). Find the point P such that PA=PB and area of triangle PAB =10 square units.

Answer»

SOLUTION

Here, P=P(X,y) be the required point.

Then,

=) PA= PB= PA^2= PB^2

=  > (x - 3) {}^{2}  + (y - 4) {}^{2}  =  {( x - <klux>5</klux>)}^{2}  +  {(y + 2)}^{2}

=) x-3y-1= 0.............(1)

Again,

Area of PAB=10

=)1/2[x(4+2)+3(-2-y)+5(y-4)]=10

=) 3x+y-23=0.............(2)

On solving (1) &(2), we get

=) x= 7 and y= 2

Hence, the required POINTS (7,2).

hope it helps ✔️
