1.	abcd is a trapezium such that ab is parallel to cd. ef is parallel to ab and cd such that ef divides trapezium in two equal areas. find ef
Answer» Answer: ABCD is trapezium in which AB∥DC. EF is PARALLEL to side DC. Then we have AB∥DC∥EF. Hence we have also trapezium ABFE and trapezium EFCD. Let AP be the PERPENDICULAR to DC and this INTERSECTS EF at Q. AQ will be perpendicular to EF. For △APD and △AQE we have EAAD=AQAP=2 This gives AP=2AQ i.e, AQ=QP Consider the area we have area ABCD= area ABFE+ area EFCD (21)AP×(AB+DC)=(21)AQ×(AB+EF)+(21)QP×(EF+DC) ⇒AP(AB+DC)=AP×2AB+AP×2EF+AP×2EF+AP×2DC ⇒AP×2AB

1.

abcd is a trapezium such that ab is parallel to cd. ef is parallel to ab and cd such that ef divides trapezium in two equal areas. find ef

Answer»

Answer:

ABCD is trapezium in which AB∥DC.

EF is PARALLEL to side DC.

Then we have AB∥DC∥EF.

Hence we have also trapezium ABFE and trapezium EFCD.

Let AP be the PERPENDICULAR to DC and this INTERSECTS EF at Q.

AQ will be perpendicular to EF.

For △APD and △AQE we have EAAD=AQAP=2

This gives AP=2AQ

i.e, AQ=QP

Consider the area we have area ABCD= area ABFE+ area EFCD

(21)AP×(AB+DC)=(21)AQ×(AB+EF)+(21)QP×(EF+DC)

⇒AP(AB+DC)=AP×2AB+AP×2EF+AP×2EF+AP×2DC

⇒AP×2AB

13.	The area of a rectangular pool is at most 1260 ft². What could be the possible dimensions of the pool, if one side of the pool is 48 ft more than three times the other side?
Answer» Let : Larger SIDE of pool = x Smaller side of pool = y Given : Area of rectangular pool = 1260 ft² Larger side is 48 ft more than three TIMES the snaller side To find : Sides of pool Formula used : 1) Area of rectangle = length× breadth { Here Area of rectangular pool = larger side × smaller side } $\sf 2) \: a {y}^{2} + bx + c = 0 \\ \\ \sf \implies \: x \: = \: \dfrac{ - b \: \pm \: \sqrt{ {b}^{2} - 4ac } }{2a}$ Solution : We , know that Larger side is 48 ft more than three times the snaller side ➝ x = 48 + (3y) .... equation 1 _______________________________________________ Also , given that area of rectangular pool = 1260 ft² ➝ xy = 1260 .... equation 2 _______________________________________________ Putting value of x from equation 1 into equation 2, we get; ➝ (48 +3y) y = 1260 ➝ 3y² + 48y = 1260 Dividing both side by 3 , we get; ➝ y² + 16y = 420 ➝ y² + 16y - 420 = 0..... equation 3 _______________________________________________ Comparing equation 3 , with general FORM of quadratic equations { ay² + by + c = 0}, we get a = 1 b = 16 c = -420 Using quadratic formula , and solving for y $\sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: \sqrt{ {16}^{2} - 4 \times 1 \times ( - 420) } }{2 \times 1} \\ \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: \sqrt{ 256 + 1680} }{2 } \\ \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: \sqrt{ 1936} }{2 } \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: 44}{2 } \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 }{2} \: \pm \: \dfrac{44}{2} \\ \\ \sf \implies \: y \: = \: - 8 \: \pm \: 22$ This give , EITHER , y = -8 + 22 ......or .....y = -8 -22 either , y = 14 ........or........ y = -30 { as side cannot be negative , y ≠ -30 } Therefore, y = 14ft _______________________________________________ Putting value of y in equation 1 we get, ➝ x = 48 + 3(14) ➝ x = 48 + 42 ➝ x = 90 ft _______________________________________________ ANSWER : Larger side = 90 ft Smaller side = 14 ft

13.

The area of a rectangular pool is at most 1260 ft². What could be the possible dimensions of the pool, if one side of the pool is 48 ft more than three times the other side?

Answer»

Let :

Larger SIDE of pool = x
Smaller side of pool = y

Given :

Area of rectangular pool = 1260 ft²
Larger side is 48 ft more than three TIMES the snaller side

To find :

Sides of pool

Formula used :

1) Area of rectangle = length× breadth

{ Here Area of rectangular pool = larger side × smaller side }

$\sf 2) \: a {y}^{2} + bx + c = 0 \\ \\ \sf \implies \: x \: = \: \dfrac{ - b \: \pm \: \sqrt{ {b}^{2} - 4ac } }{2a}$

Solution :

We , know that Larger side is 48 ft more than three times the snaller side

➝ x = 48 + (3y) .... equation 1

_______________________________________________

Also , given that area of rectangular pool = 1260 ft²

➝ xy = 1260 .... equation 2

_______________________________________________

Putting value of x from equation 1 into equation 2, we get;

➝ (48 +3y) y = 1260

➝ 3y² + 48y = 1260

Dividing both side by 3 , we get;

➝ y² + 16y = 420

➝ y² + 16y - 420 = 0..... equation 3

_______________________________________________

Comparing equation 3 , with general FORM of quadratic equations { ay² + by + c = 0}, we get

a = 1
b = 16
c = -420

Using quadratic formula , and solving for y

$\sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: \sqrt{ {16}^{2} - 4 \times 1 \times ( - 420) } }{2 \times 1} \\ \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: \sqrt{ 256 + 1680} }{2 } \\ \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: \sqrt{ 1936} }{2 } \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 \: \pm \: 44}{2 } \\ \\ \sf \implies \: y \: = \: \dfrac{ -16 }{2} \: \pm \: \dfrac{44}{2} \\ \\ \sf \implies \: y \: = \: - 8 \: \pm \: 22$

This give ,

EITHER , y = -8 + 22 ......or .....y = -8 -22

either , y = 14 ........or........ y = -30

{ as side cannot be negative , y ≠ -30 }

Therefore, y = 14ft

_______________________________________________

Putting value of y in equation 1 we get,

➝ x = 48 + 3(14)

➝ x = 48 + 42

➝ x = 90 ft

_______________________________________________

ANSWER :

Larger side = 90 ft
Smaller side = 14 ft

To change the ratio from 4:3 to 2:4, how . need to be added in semixture?045556535

Answer»

Answer:

45

Step-by-step explanation:

to find the real quantities

4:3 will be considered as 4x+3x =105 (let x be the constant)

7x= 105

x=15, so MILK is 60 LITRES and water is 45 litres

now to make it into 2:4 all we need to do is add some extra quantity

105 + y = 2z+4z

105+y = 6z

now from the given options check that what Value can be added to 105 so that it is divisible by 6

i.e 45

by adding 45

105+45 = 6z

150= 6z

z=25

the new quantities are 50 milk: 100 water i.e 2:4
