|
Answer» Step-by-step EXPLANATION: What is the DISADVANTAGE in comparing line segments by MERE observation? ... When we compare two line segments of ALMOST the same lengths, we cannot be sure about the line segment of greater LENGTH. Therefore, it is not an appropriate method to compare line segments having a slight difference between their lengths. |

Write an equation in slope-intercept form that goes through the points (5, 2) and (-3, -3). |
Answer» Answer:-Given points are (5 , 2) , ( - 3 , - 3). We know that, Equation of a LINE in slope intercept form is : y - y₁ = m(x - x₁)where m is slope of the line and (x₁ , y₁) is the first point. Slope of a line (m) = (y₂ - y₁) / (x₂ - x₁)Let ,
So, ⟹ m = ( - 3 - 2) / (- 3 - 5) ⟹ m = - 5 / - 8 ⟹ m = 5/8Now, REQUIRED equation of the line is : ⟹ y - 2 = (5/8) (x - ( - 3)) ⟹ (y - 2) × 8 = 5 (x + 3) ⟹ 8y - 5x - 16 - 15 = 0 ⟹ 8y - 5x - 31 = 0∴ The required equation of the line is 8y - 5x - 31 = 0. |

Is the triangle with length of itssides,a=7cm,b=24cm=and=25cm a right- angled triangle |
Answer» ☆ Solution ☆Given :-
Step-by-Step-Explaination :-As we know that :- In right triangle, the square of the hypotenuse length is equal to the sum the squares of BASE and perpendicular length . Hypotenuse² = Perpendicular² + Base² As givenA = 7cm B = 24cm C = 25cm a right angle triangle . As hypotenuse sides is ALWAYS greater length side i.e 25 cm . (25)² = (24)² + (7)² 625 = 576 + 49 625 = 625 THUS the square of the hypotenuse length is equal to the sum the squares of base and perpendicular length . Therefore,A = 7cm B = 24cm C = 25cm is a right angled triangle. |

3. solve for x and y , x-1 / x-2 + x-3 / x-4 = 10/3. |
Answer» To Solve:-Required Answer:-For SOLVING for x, we have to take the LCM i.e. (x - 2)(x -4). Then, ⇒ Cross multiplying for easier calculation: ⇒ Multiplying the terms inside the CURLY brackets: ⇒ OPENING the parentheses, ⇒ ⇒ Taking 2 as a common from both sides & cancelling it, we have, ⇒ Now shifting the terms to one SIDE of the equation: ⇒ ⇒ Now find the possible values of x by Middle term factorisation, ⇒ ⇒ ⇒ Equating to 0, We get ⇒ Hence:-

a 100 kg mixture of two different types of nuts costa $550. if type A costs $4 per kg and type B costs $7 per kg, how many of each type were used? |
Answer» Given:A 100 kg mixture of two different types of nuts costa $550. If type A costs $4 per kg and type B costs $7 per kg To find:How many of each type were used? Solution:Let's assume, "x" kg → represents the quantity of type A used "y" kg → represents the quantity of type B used The total quantity of the mixture of nuts used = 100 kg ∴ Type A costs $ 4 per kg, type B costs $ 7 per kg and the total cost of the mixture $ 550 ∴ On multiplying eq. (i) by 4, we get
On subtracting eq. (iii) from eq. (ii), we get - - - --------------------- ---------------------- ∴ On substituting the VALUE of y in eq. (i), we get
Thus, 50 kg of each type of nuts were used. ------------------------------------------------------------------------------------------- ALSO View:A nut mix contains almonds, cashews and macadamia nuts in the ratio of 20 : 10 : 2. If there are 640 nuts in the bag, how many macadamia nuts are there? There are 2 types of mixed nuts. Type a and type b. 1/3rd of type a nuts and 2/5th of type b nuts are peanuts. A mixture of 2 1/2kg of type a and 5 1/2 kg of type b are mixed together what fraction of this mixture is peanut two varieties of cashew nuts costing ₹650 and ₹900 kg are mixed in the ratio of 2 : 3 to create a NEW variety. if the mixed variety is sold at rupees 900 per kg, find the gain or loss per cent A trader mixes three varieties of groundnuts costing Rs. 50, Rs. 20 and Rs. 30 per kg in the ratio 2: 4: 3 in terms of weight, and sells the mixture at Rs. 33 per kg. What PERCENTAGE of profit does he make? |

If a transversal intersects two line such that the bisectors of corresponding angels are parallel,then prove that the tow line are parallel |
|
Answer» The transversal AD intersects the two lines PQ and RS at POINTS B and C RESPECTIVELY. BE is the bisector of ∠ABQ and CF is the bisector of ∠BCS. As, BE is the bisector of ∠ABQ, then, ∠ABE= 2/1∠ABQ In the same WAY, ∠BCF= 2/1 ∠BCS Since BE and CF are PARALLEL and AD is the transversal, therefore, by corresponding angle axiom, ∠ABE=∠BCF 2/1∠ABQ= 2/1∠BCS ∠ABQ=∠BCS Therefore, by the converse of corresponding angle axiom,PQ∥RS. |
