(8) Water in a canal, 6 m wide and 1.5 m deep, is flowing with a speed of 1 0 km/h. How mucharea will it irrigate in 30 minutes, if 8 cm of standing water is needed? |
|
Answer» Speed of flowing of water from canal is 10km/h , means length of water flows in 1 hour = 5 km , so length of water flows in 30 minutes = 5km Now, volume of water flowing from canal = length of water flows in 30 minutes × breadth of canal × deep of canal = 5000m × 6m × 1.5m = 45000 m³ Let area of field = x m² Then, volume of water irrigates into the field = area of field × height of water during irrigation = x m² × 8× 10⁻² m = 0.08x m³ Now, volume of water flowing from canal = volume of water in field 45000 m³ = 0.08x m³ x = 562500 m² We know, 1 hectare = 10000 m² So, area of field in hectare = 562500/10000 = 56.25 hectares please like my answer if you find it useful |

Pramod bought 100 bunches of methigreens for 400. In a sudden downpour,30 of the bunches on his handcart gotspoilt. He sold the rest at the rate of5 each. Did he make a profit or a loss?How much? |
|
Answer» Cost price of 100 bunches of methi greens = Rs 400 Number of bunches of methi greens spoilt = 30 Number of bunches left = 100 - 30 = 70 Selling price of 1 bunch of methi greens = Rs 5 So, selling price of 70 bunches of methi greens = 5 x 70 = Rs 350 Since selling price is less than cost price, so there is a loss. Loss = Cost price - Selling price = 400 - 350 = Rs 50 Hence, Pramod suffered a loss of Rs 50 in this transaction. |

atbrc = 14 -Find a b c |
|
Answer» (a+b+c)^2 = a^2 + b^2 + c^2 + 2(ab + bc + ca) (a+b+c)^2 ≥ 0 for any real values of a, b, c Therefore,a^2 + b^2 + c^2 + 2(ab + bc + ca) ≥ 0 Given that a^2 + b^2 + c^2 = 1Therefore,1 + 2(ab + bc + ca) ≥ 0 ab + bc + ca ≥ -1/2 (a-b)^2 + (b-c)^2 + (c-a)^2 ≥ 02 [ a^2 + b^2 + c^2 - ab - bc - ca ] ≥ 02 [ 1 - (ab + bc + ca)] ≥ 0Therefore, 1 ≥ (ab + bc + ca) Hence the answer is [-1/2, 1] |
