3.	The number increases by 15 gives 60 find the number
Answer» ong>Answer: Think about the definition of percent. 15% is just 15/100. If a number is DECREASED by 15%, that’s 1–15/100, which is 85/100. Therefore, x85/100=60. To isolate the x variable, you need to MULTIPLY both sides by the reciprocal of 85/100, which is 100/85. Then you GET the equation x=60100/85, which is the same as x=6000/85, which is approximately 70.59. You can CHECK your answer by substituting 70.59 into your original equation, which gives you 70.59–15/10070.59=60. 15/10070.59 is approximately equal to 10.59. Then, substituting 10.59 in for 15/100*70.59 in your original equation gives you 70.59–10.59=60, which is true. Therefore, the answer to your question is 70.59.

ong>Answer:

Think about the definition of percent. 15% is just 15/100. If a number is DECREASED by 15%, that’s 1–15/100, which is 85/100. Therefore, x*85/100=60.

Answer»

$\large\underline{\sf{Solution-}}$

CONSIDER,

$\rm :\longmapsto\:cos\bigg(\theta + \dfrac{2\pi}{3} \bigg) - cos\bigg( \theta + \dfrac{\pi}{3}\bigg)$

We know,

$\boxed{ \sf \: cosx - cosy = - \: 2sin\bigg( \dfrac{x + y}{2} \bigg)sin\bigg( \dfrac{x - y}{2} \bigg)}$

So, using this identity, we get

$\: \: = \sf \: - \: 2 \: sin\bigg( \dfrac{\theta + \dfrac{2\pi}{3} + \theta + \dfrac{\pi}{3}}{2} \bigg)sin\bigg( \dfrac{\theta + \dfrac{2\pi}{3} - \theta - \dfrac{\pi}{3}}{2} \bigg)$

$\: \: = \sf \: - \: 2 \: sin\bigg( \dfrac{\pi}{2} + \theta \bigg)sin\bigg( \dfrac{\pi}{6} \bigg)$

$\: \: \sf \: = \: - \: 2 \: cos\theta \: \times \dfrac{1}{2} \: \: \: \: \: \: \: \{ \because \:sin\bigg( \dfrac{\pi}{2} + \theta\bigg) = cos\theta \}$

$\: \: = \sf \: - cos\theta$

$\bf\implies \: \boxed{ \sf \: cos\bigg(\theta + \dfrac{2\pi}{3} \bigg) - cos\bigg( \theta + \dfrac{\pi}{3}\bigg) = - cos\theta} - - (1)$

Now, Consider,

$\rm :\longmapsto\:sin\bigg(\theta + \dfrac{2\pi}{3} \bigg) - sin\bigg( \theta + \dfrac{\pi}{3}\bigg)$

We know that

$\boxed{ \sf \: sinx - siny = 2 \: cos\bigg( \dfrac{x + y}{2} \bigg)sin\bigg( \dfrac{x - y}{2} \bigg)}$

So, using this identity, we get

$\: \: \sf \: = \:2 \: cos\bigg( \dfrac{\theta + \dfrac{2\pi}{3} + \theta + \dfrac{\pi}{3}}{2} \bigg)sin\bigg( \dfrac{\theta + \dfrac{2\pi}{3} - \theta - \dfrac{\pi}{3}}{2} \bigg)$

$\: \: = \sf \: \: 2 \: cos\bigg( \dfrac{\pi}{2} + \theta \bigg)sin\bigg( \dfrac{\pi}{6} \bigg)$

$\: \: = \sf \: - \: 2 \: sin\theta \times \dfrac{1}{2}$

$\: \: = \sf \: - \: sin\theta$

$\rm :\implies\: \boxed{ \sf \: sin\bigg(\theta + \dfrac{2\pi}{3} \bigg) - sin\bigg( \theta + \dfrac{\pi}{3}\bigg) = - sin\theta } - - (2)$

Now,

We know,

Distance between two points is given by Distance Formula.

$\: \: \: \boxed{\sf\ \:AB = \sqrt{ {(x_2-x_1)}^{2} + {(y_2-y_1)}^{2} }}$

$\sf \: where \: coordinates \: of \: A \: and \: <klux>B</klux> \: are \: (x_1,y_1) \: and \: (x_2,y_2)$

Here,

we have to find Distance between

$\rm :\longmapsto\: \sf \:A \: \bigg[a \: cos\bigg( \dfrac{2\pi}{3} + \theta\bigg), \: a \: sin\bigg(\dfrac{2\pi}{3} + \theta \bigg)\bigg]$

and

$\rm :\longmapsto\: \sf \: B \: \bigg[a \: cos\bigg(\dfrac{\pi}{3} + \theta\bigg), \: sin\bigg(\dfrac{\pi}{3} + \theta\bigg)\bigg]$

So, Distance between A and B is given by

$\sf \: AB = \sqrt{ { {a}^{2} \bigg( cos\bigg(\theta + \dfrac{2\pi}{3} \bigg) - cos\bigg( \theta + \dfrac{\pi}{3}\bigg) \bigg) }^{2} + {a}^{2} {\bigg( sin\bigg(\theta + \dfrac{2\pi}{3} \bigg) - sin\bigg( \theta + \dfrac{\pi}{3}\bigg) \bigg) }^{2}}$

$\: \: = \sf \: \sqrt{ {a}^{2} {( - cos\theta)}^{2} + {a}^{2} {( - sin\theta)}^{2}}$

$\: \: = \sf \: \sqrt{ {a}^{2} {cos}^{2}\theta + {a}^{2} {sin}^{2}\theta }$

$\: \: = \sf \: \sqrt{ {a}^{2} \bigg( {sin}^{2}\theta + {cos}^{2}\theta\bigg) }$

$\: \: = \sf \: a$

Sum to Product Formula

sin x + sin y = 2 sin [(x+y)/2] cos [(x-y)/2]

sin x – sin y = 2 cos [(x+y)/2] sin [(x-y)/2]

cos x + cos y = 2 cos [(x+y)/2] cos [(x-y)/2]

cos x – cos y = -2 sin [(x+y)/2] sin [(x-y)/2]

cot(A-B) = [(cot A cot B + 1)/(cot B – cot A)]

cos(A+B) cos(A–B)=cos^2A–sin^2B=cos^2B–sin^2A

sin(A+B) sin(A–B) = sin^2A–sin^2B=cos^2B–cos^2A

Quiz: Logic Explain that, three colinear points cannot be on a circle.

Answer»

wer Keys.

Colinear Points

Three points are colinear, so all of them are on a line.

If three are colinear, there are three cases.

There are no points in common.
There are TWO points in common.
All of them are in common.

Number of Intersections

We know that the maximum number of intersections, that a circle and a line can have is two.

Definition of Circle

A circle is a figure that the radius is equal.

Solution.

For cases 2 and 3, let's exclude them.

We know the maximum number of intersections is 2. Based on that, let's find the TOTAL number of ways.

Location of the center?
The pair of intersections?

There are three ways to choose the pair of points and two ways to choose a center. Total of 6 different circles.

Now there are two general cases.

ONE point is outside the circle. (4 circles)
One point is inside the circle. (2 circles)

In either way, the circles cannot go through one point because the distance is different from the two points.

More information.

If one point is outside the circle, the distance from the circle is greater than the radius.

If one point is inside the circle, the distance from the circle is less than the radius.

Find the length and breadth of rectangle having breadth x+yand 3x-2y and length x+7 and x+8

Answer»

ong>Step-by-step explanation:

length = 15 units and breadth = 12.5 units

Step-by-step explanation:

I think these are the dimensions of sides as shown in the attachment.

So, we know that rectangle has length and breadth

i.e.

\BEGIN{gathered}x + 7 = 3x - 2y \\ \\ x - 3x + 2y = - 7 \\ \\ - 2x + 2y = - 7 \\ \\ 2x - 2y = 7...eq1 \\ \\ \END{gathered}

x+7=3x−2y

x−3x+2y=−7

−2x+2y=−7

2x−2y=7...eq1

and

\begin{gathered}x + y = y + 8 \\ \\ x + y - y = 8 \\ \\ x = 8 \\ \\ \end{gathered}

x+y=y+8

x+y−y=8

x=8

So,

\begin{gathered}2(8) - 2y = 7 \\ \\ - 2y = 7 - 16 \\ \\ 2y = 9 \\ \\ y = 4.5 \\ \\ \end{gathered}

2(8)−2y=7

−2y=7−16

2y=9

y=4.5

Now, length of rectangle is

\begin{gathered}x + 7 \\ \\ = 8 + 7 = 15 \: unit \\ \\ 3x - 2y = 24 - 9 = 15 \: unit \\ \\ \end{gathered}

x+7

=8+7=15unit

3x−2y=24−9=15unit

Breadth

\begin{gathered}x + y = 8 + 4.5 = 12.5 \\ \\ y + 8 = 4.5 + 8 = 12.5 \: units \\ \\ \end{gathered}

x+y=8+4.5=12.5

y+8=4.5+8=12.5units

Hope it HELPS you.

★ 103×107

= (100+3)(100+7)

= 100 ² + (3+7)(100) +3 × 7

= 10000 + 1000 + 21 = 11021

★ 95×96

= (90+5) (90+6)

= 90 ²+ ( 5+6 )( 90) + 5 × 6

= 8100 + 990 + 30 = 9120

★ 104 × 96

= (100 + 4 ) + (100 - 4 )

= (100 ² ) - 4²

= 10000 - 16 = 9984

Open in ANSWR app

Step 1: Draw a line segment AB of 11cm

XY+YZ+ZX=11cm

Step 2: USING a protractor mark 30∘ at A, i.e ∠PAB and ∠QBA as 90∘

Step 3: Bisect 30∘ at A, i.e ∠PAB and ∠QBA at point X.

Step 4: Join XZ and make XZ perpendicular to AB.

Step 5: Draw perpendicular BISECTOR of AX i.e ST.

Step 6: Mark the point Y where ST and AB intersect. Join XY

∴ We get △XYZ
