The difference of 3/root6 |
|
Answer» ong>Step-by-step explanation: Explanation: First put change the words into an equation: √ 3 × √ 6
Now you can multiply them TOGETHER as you would NORMALLY multiply: √ 3 × √ 6 = √ 18
Now let's prime factor 18 and see if there are any squares that we can take out of it to simplify. All we have to see is if there are 2 numbers that are the same:
18
/ \
6 3
/ \
2 3
As you can see, we have a SQUARE: 3 × 3 = 9
So take √ 9 out of √ 18 . You should have: √ 9 √ 2
But since √ 9 = 3 we can simplify further to make: √ 9 √ 2 → 3 √ 2Explanation: First put change the words into an equation: √ 3 × √ 6

The angles of quadrilateral are in the ratio 1:2:3 and the sum of the smallest and the greatest angle is 180° find all angles of the quadrilateral |
|
Answer» ong>Answer: Dear Student, ● Answer - 45°, 90°, 90° and 135° ◆ Explanation - Given that 3 angles are in ratio 1:2:3. LET x be common multiple such that angles become x, 2x and 3x. We have, sum of SMALLEST angle and greatest angle is 180 degree. x + 3x = 180° 4x = 180° x = 180°/4 x = 45° These 3 angles become, x = 45° 2x = 2×45 = 90° 3x = 3×45 = 135° Sum of all angles of QUADRILATERAL is 360°. 45° + 90° + 135° + 4th angle = 360° 270° + 4th angle = 360° 4th angle = 360° - 270° 4th angle = 90° So four angles of quadrilateral are 45°, 90°, 90° and 135°.

Travelling at 80 kmph a person can reach his destination in a certain time. He covers 3 /4 of the journey in 4/ 5 of the total time. At what speed should he travel the remaining distance to reach his destination on time? |
|
Answer» ong>Answer: 100 km/h Step-by-step explanation: We can solve this in two ways, I will show you both ways, so here we GO......... Method 1 Let the Total Distance for the Journey be 'D' km and Total Time be 'T' hrs Thus, D/T = 80 km/h ---- 1 Now, According to the Question, He travelled 3/4 of the distance in 4/5 of time That is, (3/4)D in (4/5)T Now, distance left = D - (3/4)D = (4/4)D - (3/4)D = (1/4)D and time left = T - (4/5)T = (5/5)T - (4/5)T = (1/5)T Thus, we need to find the speed required to travel (1/4)D in (1/5)T Speed = Distance/Time = (1/4)D ÷ (1/5)T = D/4 × 5/T = 5/4(D/T) From eq.1 we get D/T = 80 km/h Speed = (5/4) × (80) Speed = 100 km/h Thus, he must travel with a speed of 100 km/h to reach his destination on time. Method 2 We know that, Total Distance covered ÷ Total time taken = 80km/h Let the certain time mentioned here be 'x' hrs Speed = Distance/Time then, Distance = Speed × Time Distance = 80 × x = 80x km Now, He covers 3/4 of the distance in 4/5 of the time so, Distance covered = 80x × (3/4) = 60X km and the time taken = x × (4/5) = (4/5)x Now the distance left = 80x - 60x = 20x km So, he has 20x km more to finish his journey Time left = x - (4/5)x = (5/5)x - (4/5)x = (1/5)x So, he has (1/5)x more to finish his journey Now, He has to complete 20x km in (1/5)x hrs then, Speed = 20x/(1/5)x = 20x ÷ (1/5)x = 20x × (5/x) = 20 × 5 = 100 km/h Thus, he must move with a speed of 100 km/h to reach the destination on time. Hope it helped and you UNDERSTOOD it........All the best |

That varies emesand00436. A part of monthly expenditure of a family is constant and the remainingvaries with the price of wheat. When the price of wheat is 800 perquintal, the total monthly expenditures is 5400 and when it is ? 1000per quintal, the total monthly expenditure ? 6000. Find the total monthlyexpenditure of the family when the cost of wheat is 950 per quintal |
|
Answer» ong>Answer: The total monthly expenditure of the family when the cost of wheat is 950 per quintal is Rs. 5850 Step-by-step EXPLANATION: Let the constant monthly expenditure be Rs.'x' and the amount of wheat they buy be 'y' Quintal We KNOW that, Monthly expense (constant) + (Rate × amount of wheat) = Total monthly expenditure Now, ACCORDING to the Question, Case 1 x + 800y = 5400 ----- 1 Case 2 x + 1000y = 6000 ------ 2 Let's Subtract eq.1 from eq.2, we get, x + 1000y = 6000 – x + 800y = 5400 ———————————— 0 + 200y = 600 ———————————— y = 600/200 = 3 Putting y = 3 in eq.2 we get, x + 1000(3) = 6000 x = 6000 - 3000 = 3000 Thus, the family has a monthly expense of Rs.3000 and then buy's additional 3 Quintals of wheat Now, If the rate of wheat comes to Rs.950 per Quintal then the family's total monthly expenditure = 3000 + 950(3) = 3000 + 2850 = Rs. 5850 Thus, the total monthly expenditure of the family when the cost of wheat is 950 per quintal is Rs. 5850 Hope it helped and you understood it........All the best |
