A student said he cannot subtract 1.97 from 20 because 1.97 has two decimal digits and 20 has none. Do you agree with this state

MariettaO [177]

Answer:

No.

Step-by-step explanation:

You can still subtract 1.97 from 20 because 20 is a whole number. .97 is not a whole number, and you can subtract it from 20.00.

1)Find the cost of fencing a rectangular park of length 175m and breadth 125m at the rate of 12/Rs per metre.

CaHeK987 [17]

Step-by-step explanation:

Length of rectangular park = 175 m

Breadth of rectangular park = 150 m

Perimeter of park = 2 x (length + breadth)

= 2 x (175 + 150)

= 2 x 325 = 650 m

Since, cost of fencing park per meter = = Rs. 12

Therefore, cost of fencing park of 600 m = 12 x 650 = Rs. 7,800

Square park=250m

Perimeter of the square park x 4

=250x4

=1000m

So, the cost of the fencing at the park would have a rate of 20 per m = 1000x20

=20000

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left. Then net force acting on the box IS 65N

<h3>What is net force?</h3>

Net force is final force acting on any object .

Here given that

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left

So we can see it in diagram that force in upper direction and lower direction is same 100N so this force will be cancelled out

Now force in right side is 75N and in left side force is 10N

So net force = (75-10)=65N in right side

A box sits on a table. A short arrow labeled F subscript N = 100 N points up. A short arrow labeled F subscript g = 100 N points down. A long arrow labeled F subscript P = 75 N points right. A short arrow labeled F subscript f = 10 N points left. Then net force acting on the box IS 65N
