A tub is filled with 18000 cm3 of water. It loses one-tenth of its water every 12 hours. What volume of water would be remaining
Lina20 [59]

Answer:

0 cm³

Step-by-step explanation:

the lost of water =

(5×24)/12 x 1/10 × 18000

= 10/10 × 18000 = 18,000 cm³

so, the remaining water in the tub=

18,000 - 18,000 = 0 cm³

(the tub is empty)

Please help. I’ll mark you as brainliest if correct!
tatyana61 [14]

Answer:

Dave worked 60 hours.

Step-by-step explanation:

Let's assume that Dave worked a total of x hours.

Since Kate worked 5 hours less than Dave: x-5

And Sarah worked 10 more hours than Dave: x+10

Combined, the three siblings worked 185 hours.

(x)+(x+10)+(x-5) = 185\\x+x+10+x-5 = 185\\3x + 5 =185\\3x = 185 - 5\\3x = 180\\x = 180 \div 3\\x = 60

Dave worked 60 hours,

Kate worked 55 hours and Sarah worked 70 hours.

To check:

55 + 60 + 70 = 185 hours

This is number the 2
Andru [333]

Answer:

Step-by-step explanation:

I can see why you are having a little bit of trouble with this. The equation is not very well explained. I take it that y is the number of blooms total that each rose bush has. The "y intercept" is 4 which means that the bush has 4 blooms. In order to have just 4 blooms it means that x = 0 -- she hasn't added any fertilizer.
