A balloon seller sells each balloon at a profit of rupees 2 and earns a total profit of rupees50. Express the situation as a linear equation.

Answer»

Answer:

C.P of 12 balloons = 10

C.P of 1 BALLOON = 10/12 = 5/6

S.P of 10 balloons = 12

S.P of 1 balloon = 12/10 = 6/5

Profit = S.P - C.P

= 6/5 - 5/6

= (36 - 25)/30

= 11/30

Profit % = ( Profit/C.P ) × 100

= {(11/30)/(5/6)} × 100

= (11/30) × (6/5) × 100

= 44%

The age of Ashwini's mother is 5years more Than twice of Ashwini's Age. After 10 years, her mother's age will be 08 years less than thrice her age. Find their present age

Answer»

Answers

✩ Present AGE of Ashiwini = 23  YEARS .

✩ Present age of Ashiwini's mother = 51 years.

SOLUTION

Let us Assume that the Present age of Ashiwini as 'x' years.

Case :- 1

The age of Ashwini's mother is 5years more Than twice of Ashwini's Age.

\implies

The Present age of Ashwini's mother = 2x + 5 \longrightarrow(1)

Case :- 2

After 10 years, her mother's age will be 08 years LESS than thrice her age.

\implies

Age of Ashwini's mother after 10 years = 3X - 8\longrightarrow(2)

We have found in (1) that the present age of Ashwini's mother is 2x + 5 , so after 10 years it will be

2x + 5 + 10 = 2x + 15 \longrightarrow(3)

Now, Let us equate Equations (2) and (3)

\implies

2x + 15 = 3x - 8

\implies

3x - 2x = 15 + 8

\implies

x = 23 years

Present age of  Ashiwini (x) = 23 years.

Now , we can FIND the present age of Ashwini's mother by substituting 'x' as 23 in Equation (1) .

\implies

The Present age of Ashwini's mother = 2 × 23 + 5

\implies

The Present age of Ashwini's mother = 46 + 5

\implies

The Present age of Ashwini's mother =  51 years.

a rectangle lawn 80 m * 60 m has two roads each 10 m wide running in the middle of it. one is parallel to the length and the other is parallel to the breath. find the cost of levelling them at 30 paise per sq. m.?

Answer»

Answer:

Answer

REF.Image

The COST of gravelling them at Rs. 1.20 per square meter = Rs . 1560

To find the area of roads :

It is given that

a rectangular LAWN 80 m × 60 m has two roads each 10 m WIDE running in the middle of it.

Dimension of two roads are 80×10 and 60×10

Area of two roads = 80×10+60×10−10×10

=800+600−100

= 1300 sq. meter

To find the cost for gravelling

It is given that

The cost of gravelling the at Rs. 1.20 per sq. meter.

Therefore total cost = total area × cost per sq. meter

=1300×1.20

=Rs.1560

∴ The cost of gravelling them at Rs. 1.20 per sq. meter = Rs. 1560

solution

In a circle of diameter 42cm,if an arc subtends an angle of 60˚ at the centre where π = 22/7, then what will be the length of arc.​

Answer»

Step-by-step explanation:

Given:-

In a circle of diameter 42cm,if an arc subtends an angle of 60˚ at the centre where π = 22/7.

To find:-

what will be the LENGTH of arc.

Solution:-

Diameter of a circle (d)=42 CM

=>RADIUS of the circle (r)=Diameter/2

=>r=42/2=21 cm

An angle subtends by the arc =(x)=60°

Length of the arc (l)=x°×2πr/360° units

=>60°×2×(22/7)×21/360°

=>(60°×2×22×21)/(7×360°)

=>2×22×3/6

=>22

Length=22 cm

Answer:-

Length of the arc for the given PROBLEM is 22 cm

Used formula:-

If the radius of the circle is" r "units and the angle subtended by the arc in the circle is x° then the length of the arc is (x°×2πr)/360

π=22/7

Simplify 15(y-4)+2(y-9)+(y+6)=0 Can anyone tell the answer​

Answer»

\sf\huge\bold{\underline{\underline{{Solution}}}}

15(y-4)+2(y-9)+(y+6)=0

Step 1: first we will expanding the terms

➠15×y-4×15+2×y-9×2+y+6=0

➠15y-60+2y-18+y+6=0

Now, terms are unarranged so ,we first arrange the term by placing like terms together means terms of same Variable together.

➠15y+2y+y-60-18+6=0

Solving CONSTANT term

Concept: plus minus =minus

minus minus =plus (but we PUT sign of -)

➠15y+2y+y -78+6=0

15y+2y+y -72=0

solving first term or Variable terms

➠18y-72=0

-72 is negative on the left side when we shifts it towards right side it's sign GETS changed.

➠18y=72

we KNOW 72 comes up in multiples of 18

➠y=72÷18=4

y=4

Check

15(y-4)+2(y-9)+(y+6)=0

=>15(4-4)+2(4-9)+(4+6)

=>15×0+2×-5+10

=>0-10+10=0+0=0
