A and b can do a piece of work in 12 days. If a alone have to finish the job among b and c so

A and b=12
A (24 days alone without b)

So if b and c 15 days and c 20 days. If a have to do all I would add 24 and 15 and 20 which would be 59 days

Two other ways to write 0.632
larisa86 [58]
Two other ways to write 0.632 is to turn it into a percent. To turn 0.632 into a percent just multiply it by 100. You can do this simply by moving the decimal point to the right twice and adding the percent sign: 63.2%
Another way is by fraction form. To put in in fraction form just look at the decimal and see which is the last place. The last placement it a thousandth. So your denominator is automatically 1000. Then, you look at the decimal and write the decimal and disregard the zero. The fraction you get is 632/1000. Hope this answer helps and mark as brainliest!

The vertical asymptote is x = ?<br>y=a/x-h +k​
gtnhenbr [62]

Answer:

x=a/(y-k)+h

Step-by-step explanation:

y-k=a/(x-h)

(y-k)(x-h)=a

xy-hy-kx+kh=a

xy-kx=a+hy-hk

x(y-k)=a+h(y-k)

x=a/(y-k)+h

artcher [175]

Answer:

BC= 2√5

CD= 2√10

DE= 2√5

BE= 2√10

slope of BC = 2

slope of CD = 1/3

slope of DE = 2

slope of BE = 1/3

Step-by-step explanation:

formula for distance = √(x2-x1)²+(y2-y1)²

formula for slope = (y2-y1)/(x2-x1)
