The temperature of Bangalore on a sunny day was 20°C in the morning. The temperature increased by 19°C by noon. It at that temperature for 5 hours & then decreased by 15°C. What would be the temperature of the city at 8 pmPlease answer this question I will mark them as brainlilist |
Answer» Solution :-At 12 noon, the temperature = 10° C above zero The temperature is decreasing at 2° C per hour 8° C below zero = - 8° C So, total fall in temperature from 10° C to 0° C and from 0° C to - 8° C = 18° C Since the temperature falls 2° C in EVERY one hour. Therefore, to decrease 18° C, time TAKEN = 18/2 = 9 hours Present time is 12 noon so, the time when the temperature is - 8° C = 12 noon + 9 hours So, The time at which the temperature will be - 8° C = 9 PM At 9 PM, the temperature is - 8° C, the temperature at 12 MIDNIGHT will be = (- 8° C) + (- 2° C × 3 hours) = (- 8° C) + (- 6° C) = - 14° C So, at 12 midnight the temperature will be - 14° C. |

Write the arithmetic sequence got by adding 3 to multiples of 7 ?Write the algebraic expression of this sequence? Is 2000 a term of this sequence ? |
|
Answer» Answer: Multiple of 7 = 7 , 14 , 21 ........ 3 added = 10 , 17 , 24 ........ an = a + (n - 1) d an = 10 + (n - 1) 7 an = 10 + 7n - 7 an = 7n + 3 Let 2000 be nth term of A.P. an = a + (n - 1) d 2000 = 10 + (n - 1) 7 2000 = 10 + 7n - 7 2000 = 7n + 3 7n = 1997 n = 1997/7 (n ≠ whole number) Hence, 2000 is not a term of A.P.

|
Answer» Answer: Given : T is a point on QR such that QT : TR = 3 : 5. U is a point on PR such that PU : UR = 3 : 5, To Find : VALUE of UT in terms of PQ Solution: QT : TR = 3 : 5 => QT/TR = 3/5 => QT/TR + 1 = 3/5 + 1 => (QT + TR)/TR = (3 + 5)/5 => QR/TR = 8/5 PU : UR = 3 : 5 => PU/UR = 3/5 => PU/UR + 1 = 3/5 + 1 => PR/UR = 8/5 Comparing Δ UTR & ΔPQR QR/TR = PR/UR = 8/5 ∠R is common Hence Δ UTR ≈ ΔPQR ( SAS CRITERIA ) => UT/PQ = UR/PR => UT/PQ = 5/8 => UT = (5/8) PQ |
