1) Study the equation m² - 5m + 3 = 0 and write the answers of the followingquestions.a) Is this a quadratic equation? Why?b) Can you solve this equation by factorization? Give reason.c) If 3 is added to left side of the given equation then can you solve the newequation by factorization. Give reason. |
Answer» Answer.a) Yes, it is. b) No, we can't. c) Yes, we can. Answer Keys.
An equation having the highest degree of 2.
Showing an expression as products. Solution.a) This equation has the highest degree of 2, because of b) We cannot solve it through factorization, because this will involve square roots[1]. c) The NEW equation is More information.[1] We can solve Methods of Solving Quadratic Equation
For the expression to be zero, each factor needs to be zero. However, this may not work for some equations.
This involves the concept of the square root. This method is not used because it uses a lot of time.
This is a more generalized method of complete the square method. This works where factorization doesn't work. |

Abus travelled from village A to village B at a speed of 40 km per hour. On thereturn journey its speed was 60 km per hour. What is the average speed of thebus during the entire journey?(1) 50 km/h (2) 48 km/h (3) 46 km/h (4) 45 km/h |
Answer» Given :• A bus travelled from village A to village B at a speed of 40 km per hour. • On the return journey its speed was 60 km per hour. To calculate :• Average speed during the entire journey. Calculation :Let the distance from A to B be d km. We know that, Firstly it travels from A to village B and then it returns from B to A. ➠ Distance from A to B = d ➠ Distance from B to A = d ➛ Total Distance = Distance from A to B + Distance from B to A ➛ Total Distance = ( d + d ) km ➛ Total Distance = 2d km As we know that, Time taken to COVER the distance from A to B (t₁): ➠ t₁ = Time taken to cover the distance from B to A (t₂): ➠ t₂ = ➛ Total time = t₁ + t₂ ➛ Total time = ➛ Total time = ➛ Total time = ➛ Total time =
Now, SUBSTITUTING the VALUES in the formula of average speed to find the average speed of the bus during the entire journey. ➛ Average speed = ➛ Average speed = ➛ Average speed = ➛ Average speed = 48 km/h Therefore, average speed of the bus during the entire journey is 48 km/h. Option ⑵ is correct. |

An oll tin contains 3x 3/4 litres of which 2x 1/2 litres of oil is usedHow much oil is left over ? |
|
Answer» Answer: An OIL tin contains 3 3/4 litres of oil of which 2 1/2 liters of oil is used. To find : How much oil is left over? Solution: AMOUNT of oil in a tin = 3 \frac{3}{4}3 4 3
Amount of oil in a tin = \frac{15}{4} 4 15
Amount of oil used =2 \frac{1}{2}2 2 1
Amount of oil used =\frac{5}{2}= 2 5
So, Amount of oil left = \frac{15}{4}-\frac{5}{2} 4 15
− 2 5
Amount of oil left = \frac{5}{4} 4 5
Amount of oil left =1 \frac{1}{4}=1 4 1
Hence1 \frac{1}{4}1 4 1
liters of oil is left |

.If selling an article for ₹820 causes 10% loss on the selling price,then find itsb costprice. |
Answer» Solution!!The concept of profit and LOSS has to be used here. The selling price (SP) and loss PERCENTAGE is given. We have to find the cost price (CP). Loss% = 10 Selling price (SP) = Rs 820 SP = CP × (100 - Loss%)/100 820 = CP × (100 - 10)/100 820 × 100 = CP × 90 82000 ÷ 90 = CP CP ≈ Rs 911.11 Hence, the cost price is Rs 911.11 More information:-If SP>CP, then it is profit. If CP>SP, then it is loss. Profit = SP - CP Loss = CP - SP Profit% = (Profit/CP) × 100 Loss% = (Loss/CP) × 100 CP → Cost Price SP → Selling Price |
