Step-by-step EXPLANATION:

₹400

ANSWER:

C is the CORRECT OPTION

EXPLANATION.

Graph of the equation.

⇒ 3X - y = 0.

As we know that,

PUT the value of x = 0 in equation, we get.

⇒ 3(0) - y = 0.

⇒ 0 - y = 0.

⇒ y = 0.

Their Co-ordinates = (0,0).

Put the value of y = 0 in equation, we get.

⇒ 3x - (0) = 0.

⇒ 3x = 0.

⇒ x = 0.

Their Co-ordinates = (0,0).

Answer:

Step-by-step explanation:

et WEIGHT of a apple be X

weight of 5 apple=5x

so weight 3 apple =3x-9.8 G

ANSWER:

The VALUE is 130

Step-by-step explanation:

20% of 650

20/100 X 650

2  x 65

=   130

ANSWER:

I don't KNOW this answer, but I HOPE ANYBODY HELP you

Its IMPOSSIBLE to do because when we ADD odd no. By odd times the sum also comes in odd but there is a method to do it USE 3!=6......X=3!Y=9Z=5Ans is 30

Since father and MOTHER are adults'
fee for father and mother = 2×9 = Rs. 18

RAGHAV and his BROTHER are both 14 years OLD. They are more than 12. So
fee for raghav and his brother = 2×9 = Rs. 18

Both his SISTERS are less than 12,
fee for his sisters = 2×4 = Rs. 8

Total charge = 18+18+8 = Rs.44

Angle DAB + angle DCB = 180      (sum of opposite sides of a CYCLIC QUADRILATERAL)
angleDCB +50 =180
angle DCB =130
.'. angle y= 130

'.' OA=OB                                    (radius of circle)
angle OAB = angle OBA = 50        (angles opposite to equal sides are equal)
angle OAB + angle OBA = angle BOD      (exterior angle property of triangle)
50 +50 =angle x
100 =angle x

M = LOG 20 

n = log 25

so 2LOG (x - 4) = 2m - n

⇒  log (x - 4)² = 2log20 - log25

⇒ log(x - 4)² = log (20² / 25)

cancelling log from both sides

(x - 4)² = 20² / 25 

⇒ x - 4 = 20 / 5

x = 4 + 4 = 8 ANSWER

log 144 to the base 12 is

12 to the POWER what is equal to 144

which is 12

12^12=144

Number of roses = 240
cost = RS. 10 PER dozen
number of dozens = 240/12 = 20 dozens
cost price = 20×10 = Rs. 200

he SOLD them at Rs. 1.50 each
selling price = 240×1.50 = 360

profit = 360 - 200 = Rs. 160

% profit = 

He earned 80% profit.

60:8sq is the COST FUNCTION

When a line segment JOINING the POINTS (x₁,y₁) and (x₂,y₂) is trisected at points P and Q, the coordinates of the points P and Q are given by:



If P(3,-2) lies on 2x-y+K=0;
2×3 - (-2) + k = 0
⇒ 6 + 2 + k = 0
⇒ k + 8 =0
⇒ k = -8

If Q(4,-5) lies on 2x-y+k=0;
2×4 - (-5) + k = 0
⇒ 8 + 5 + k = 0
⇒ k + 13 =0
⇒ k = -13

The time to fill TANK(together)=75/9 hr
if the SMALL tap WANTS x+10 hr
then big tap wants x hr

amount of water that fill in ONE hr by small tap=

this is a second degree EQUATION

1. A prism WHOSE base is POLYGON of "n" sides will have 
a. n+2 FACES - n lateral faces(rectangles), one top and one bottom
b. 3n EDGES - n on top, n on bottom, n on lateral surfaces
c. 2n vertices - n on top and n on bottom

2. A pyramid whose base is polygon of "n" sides will have 
a. n+1 faces - n lateral faces(triangles) and one bottom
b. 2n edges - n on bottom, n on lateral surfaces
c. n+1 vertices - 1 on top and n on bottom surface

Draw a line segment say AB
draw an ANGLE of 60 degree
draw an angle of 90 degree
bisect both the ANGLES 
:. the formed angle is 75 degree

Let principal = P
rate = R% 

for t=3 YEARS, A = 6500
A = P + PTR/100
⇒6500 = P + 3PR/100
⇒6500 = P + 0.03PR
⇒ R = (6500-P)/0.03P

for t=1.5 years, A = 5750
A = P + PTR/100
⇒5750 = P + 0.015PR
⇒ 5750 = P + 0.015P[(6500-P)/0.03P]
⇒ 5750 = P + (6500-P)/2
⇒ 5750 = P + 3250 - 0.5P
⇒ 5750 - 3250 = 0.5P 
⇒ 0.5P = 2500
⇒ P = 2500/0.5 = Rs. 5000

R = (6500-P)/0.03P = (6500-5000)/(0.03×5000) = 1500/150 = 10

Principal is Rs. 5000 and rate is 10%.

If we have to fill the 4 gaps by CHOOSING from the options given,

3 × 4 = A
or A = 12.

1 × 2 = B
or B = 2

now. A is a MULTIPLE of B.

An open box means it's TOP SURFACE is not there. So the TOTAL surface area is the SUM of lateral surface area and bottom surface area.

LSA = 2(lh+bh) = 2(1×0.5 + 0.8×0.5) = 2(0.5 + 0.4) = 1.8 m²
bottom surface area = 1×0.8 = 0.8m²

TSA = 1.8+0.8 = 2.6 m²

Sin X =sqrt5/3 which leads to x = 48.1 , now as u SAID sin is in 2nd quadrant so sin 180- x will be sin x so 180 - 48.1 GETS us x = 131.9
now TAN 131.9/2 = 2.24077

1)f(X)=5x-10
domain is (-∞,∞)
RANGE is (-∞,∞)

b)f(x)=15-√x
domain is [0,∞)
range is (-∞,15]

c)f(x)=2|x|+7
domain is (-∞,∞)
range is [7,∞)

d)f(x)=+100
domain is (-∞,∞)
range is (-∞,∞)

2×7×11×17×23+23
= (2×7×11×17 + 1) ×23
= (2618+1) × 23
= 2619×23

now factorize 2619
2619 = 3×3×3×97 = 3³ × 97
2619 × 23 = 3³ × 97 × 23 = 3³ × 23 × 97

So the PRIME factors are 3, 23 and 97.

Do the prime FACTORISATION of 35.
35 = 5×7

So the 2 PRIMES are 5 and 7.

The length of two SIDES CONTAINING angle A is 12cm and 5cm
So let AB = 12cm and AC = 5cm. BC is opposite to angle A, so BC is hypotenuse.
Using Pythagoras theorem,
BC² = AC² + AB²
⇒ BC² = 5² + 12²
⇒ BC² = 25+144
⇒ BC² = 169
⇒ BC = √169 = 13cm

Now from the centre of the circle O, draw perpendiculars to the three sides of the triangle. Note that OP=ON=OM = radius of circle = r. Now we can write that

Area of ΔABC = Area of ΔOAC + Area of ΔOAB + Area of ΔOBC
⇒ 0.5×AB×AC = 0.5×AC×ON + 0.5×AB×OP + 0.5×BC×OM
⇒ 0.5×12×5 = 0.5×( 5×r + 12×r + 13×r )
⇒ 12×5 = 5r + 12R + 13r
⇒ 60 = 30r
⇒ r = 60/30
⇒ r = 2cm

Thus the radius of the inscribed circle is 2cm.

No. of persons           No. of days           Money
        5                              20                      2480
        8                               x                        6944

RATIO of No. of persons = 5 : 8
Ratio of No. of days = 20 : x 
Ratio of Money = 2480 : 6944 = 155 : 434
No. of persons is INVERSELY proportionate to No. of days
No. of days is DIRECTLY proportionate to Money

Compound ratio of NO. of persons and Money = 8 : 5 :: 155 : 434 = (8×155):(5×434) =  1240 : 2170 = 124 : 217

Now,
20 : x = 124 : 217

124x = 20 × 217

x = 4340/124

x = 35

Let the roots of the equation x²-ax-4 = 0 be P and –p
Sum of the roots (p + (-p)) = -(-a)
THEREFORE, a = 0

The ANSWER is OPTION a

two  TICKETS for a to b=2x
three tickets for b to c=3y
2x+3y=11000
2x=11000-3y

It is not POSSIBLE because adding odd NUMBER by odd number TIMES is odd only ..its never even....for eg if we add 3 ,seven times aanswer is 21 which is odd number
