Answer»

ANSWER:

can understand what are you trying to say

Step-by-step explanation:

Given equation is 10÷10+10−10×10=10

On INTERCHANGING the symbols as suggested in option (I), the equation becomes;

10÷10−10+10×10=10

LHS = 10÷10−10+10×10=1−10+100=91



=10

So, this option does not hold GOOD.

2. Given equation is 10÷10+10−10×10=10

On interchanging the symbols as suggested in option (2), the equation becomes;

10+10÷10−10×10=10

LHS = 10+10÷10−10×10=10+1−100=−89

=10

So, this option also does not hold good.

3. Given equation is 10÷10+10−10×10=10

On interchanging the symbols as suggested in option (3), the equation becomes;

10÷10×10−10+10=10

LHS = 10÷10×10−10+10=1×10=10 = RHS.

This is correct.

4. Given equation is 10÷10+10−10×10=10.

On interchanging the symbols as suggested in option (4), the equation becomes;

10×10+10−10÷10=10

The height of equilateral triangle is 6 cm then what is the measures of its side

Answer»

$\sf\huge\underline{Answer:}$

Given, HEIGHT of equilateral TRIANGLE = 6 cm

side of the equilateral triangle be 'a'

$h = \frac{ \sqrt{3} }{2} a$

$6 = \frac{ \sqrt{3} }{2} a$

$a = \frac{12}{ \sqrt{3} } = \frac{3 \times 4}{ \sqrt{3} }$

$a = 4 \sqrt{3} \: cm$

27.

123. What is the smallest number which must be added to 1000 to make it divisibleby 300

Answer»

Answer:

900,600

Step-by-step EXPLANATION:

the SMALLEST number provide you mean integer divison is 300-1000mod 300 where mod means the modulo operation which gives the remainder of the integer division of 1000 by 300

1000 mod 300=100

300-100=200

the smallest number is then 200

as 1000 is divisible by300 but on the NEGATIVE scale-100 can be added to 1000 as 900 is divisible by 300

and

300*(-2)+200 =-400

1000(-400)=600

600is divisible by 300

Answer» Answer: Given that Length of the metallic WIRE = 24 cm Total length = 24cm Perimeter = 24 cm 1.She can make an equilateral triangle We know that the Perimeter of an equilateral triangle with a UNITS is 3a units => 3a = 24 => a = 24 /3 => a = 8 cm So she can make an equilateral triangle of 8cm each. 2.She can make a square and Rhombus Perimeter of a square or rhombus of a units side = 4 a units => 4A = 24 => a =24/4 => a = 6cm She can make a square or rhombus of 6cm each side 3. She can make a hexagon Perimeter of a hexagon of a units = 6a units => 6a = 24 => a = 24/6 => a = 4 cm She can make a regular hexagon of 4cm each 4. She can make a regular OCTAGON Perimeter of a regular Octagon of a side a units = 8A units => 8a = 24 => a = 24/8 => a = 3 cm Manasa can make a regular Octagon of 3 cm each side. 5.She can make a bi-decagon of 12 sides perimeter of a 12 sided regular polygon = 12 a => 12 a = 24 => a = 24/12 => a = 2 cm Manasa can make a 12-sided regular polygon of 2cm each side. Answer:- She can make 5 type of polygons .They are 1.Equilateral triangle 2. Square or Rhombus 3.Hexagon 4.Octagon 5. Bi-decagon (12- Sided regular polygon) Step-by-step explanation:

5) Manasa has 24cm of metallic wire with her. She wanted to make some polygons with equalsides whose sides are integral without milling into pieces values. Find how many such polygonsshe can make with the length of 24cm metallic wire?answer fastly step by step explanation

Answer»

Answer:

Given that

Length of the metallic WIRE = 24 cm

Total length = 24cm

Perimeter = 24 cm

1.She can make an equilateral triangle

We know that the Perimeter of an equilateral triangle with a UNITS is 3a units

=> 3a = 24

=> a = 24 /3

=> a = 8 cm

So she can make an equilateral triangle of 8cm each.

2.She can make a square and Rhombus

Perimeter of a square or rhombus of a units side = 4 a units

=> 4A = 24

=> a =24/4

=> a = 6cm

She can make a square or rhombus of 6cm each side

3. She can make a hexagon

Perimeter of a hexagon of a units = 6a units

=> 6a = 24

=> a = 24/6

=> a = 4 cm

She can make a regular hexagon of 4cm each

4. She can make a regular OCTAGON

Perimeter of a regular Octagon of a side a units = 8A units

=> 8a = 24

=> a = 24/8

=> a = 3 cm

Manasa can make a regular Octagon of 3 cm each side.

5.She can make a bi-decagon of 12 sides

perimeter of a 12 sided regular polygon = 12 a

=> 12 a = 24

=> a = 24/12

=> a = 2 cm

Manasa can make a 12-sided regular polygon of 2cm each side.

Answer:-

She can make 5 type of polygons .They are

1.Equilateral triangle

2. Square or Rhombus

3.Hexagon

4.Octagon

5. Bi-decagon (12- Sided regular polygon)
