Given hollow cubical box of side 0.30 m=3 dM
volume V=3^3=27 dm^3 = 27 L
Weight of box
= weight of (fresh) water (1 kg/L) displaced
= V/3 = 9 L of water = 9 kg
When water is filled so that the total weight of water equals the weight of volume of box, the top rim of the box will be at water level.
Remaining volume = 27-9=18L
height of 18L of water when water rushes in
= 18/(3^2) = 2 dm (=0.2m)
The answer to this is -5 because 2 negatives = a positive
Answer:
14 feet below the surface.
Step-by-step explanation:
2 + 19= 21-7=14
H = 2f / (m+1)
[multiply by (m+1)]
h(m+1) = 2f
[divide by 2]
f = (h (m + 1)) / 2
3b / (b+2) = 12 / (b+2)
[multiply by (b+2)]
3b = 12
[divide by 3]
b = 4
3 / (6x + 1) / 2 = 8 / (x + 4) / 3
[multiply both denominators to mike one denominator]
3 / 8(6x+1) = 8 / 3(x+4)
[expand brackets]
3 / (48x + 8) = 8 / (3x + 12)
[multiply by (48x + 8)]
3 = 8(48x + 8) / (3x+12)
[multiply by (3x+12)]
3(3x +12) = 4(48x + 8)
[simplify]
9x + 36 = 192x + 32
173x = 4
x = 4 / 173
Answer:
Step-by-step explanation:
58.6% of the total income is 17,000
let x represent the total income
58.6%(x) = 17,000...turn ur percent to a decimal
0.586x = 17,000
x = 17,000 / 0.586
x = 29010.238 rounds to 29,010.24 <== total yearly income
check...
58.6% of 29,010.24 = 17,000
0.586(29,010.24) = 17,000
17,000 = 17,000 (correct)
