Given : Two numbers 30 & 42 is given to us .

To Find : The HCF of 30 & 42 .

Solution : HCF is the highest number which divides the given two or more numbers without leaving any remainder .

So , let's find HCF ( Highest common factor ) by Division method :

= 30 ) 42 ( 1

- 30

__________

12 ) 30 ( 2

- 24

___________

6 ) 12 ( 2

- 12

___________

0 .

The last divisor is 6 .

<u>Hence </u><u>the</u><u> </u><u>HCF</u><u> </u><u>is</u><u> </u><u>6</u><u>.</u>

given the two points (-24,7) and (30,25) a. What is an equation passing through the points? b. Is (51, 33) also on the same line
kicyunya [14]
Part 1) <span>Given the two points (-24,7) and (30,25) a. What is an equation passing through the points?

step 1
find the slope m
m=(y2-y1)/(x2-x1)----></span>m=(25-7)/(30+24)----> m=18/54----> m=1/3

step 2
wit m=1/3 and the point (30,25)
find the equation of the line
y-y1=m*(x-x1)-----> y-25=(1/3)*(x-30)--->y=(1/3)*x-10+25
y=(1/3)*x+15

the answer Part 1) is
y=(1/3)*x+15

Part 2) <span>Is (51, 33) also on the same line?
</span>if the point (51.33) is on the line y=(1/3)*x+15
then
for x=51 the value of y must be 33
for x=51
y=(1/3)*51+15----> y=17+15----> y=32
32 is not 33 
so
<span>the point does not belong to the given line
</span>
the answer Part 2) is
the point does not belong to the given line

see the attached figure

The retained earnings for the year is $205,000

The firm paid out $185,000 in cash dividend

It has total equity of$4.90 million

100,000 common shares are outstanding

Therefore the earnings per share van be calculated as follows

= 390,000/100,000

= 3.9

Hence the earnings per share is $3.9
