(0,2) (4.5,0) distance formula

The distance between them = 4.93

Step-by-step explanation:

The distance between two points (x1, y1) amd (x2, y2) is

Now putting the values of (0,2) and (4.5, 0) we get,

= = 4.93 (approx)

d=sqrt(97)/2

Step-by-step explanation:

A(0,2) x1=0,y1=2

B(4.5,0) x2=4.5, y2=0

d=sqrt((x2-x1)^2 +(y2-y1)^2)

d=sqrt((4,5-0)^2+(0-2)^2)

d=sqrt((4,5)^2 +(-2)^2)

d=sqrt ((9/2)^2 +4)

d=sqrt (81/4+16/4)

d=sqrt(97/4)

d=sqrt(97)/2

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
