Given:

The expression is:

18\dfrac{2}{5}-4\dfrac{1}{10}

To find:

The difference.

Solution:

We have,

18\dfrac{2}{5}-4\dfrac{1}{10}

It can be rewritten as:

=\dfrac{90+2}{5}-\dfrac{40+1}{10}

=\dfrac{92}{5}-\dfrac{41}{10}

Taking LCM, we get

=\dfrac{184-41}{10}

=\dfrac{143}{10}

=\dfrac{140+3}{10}

=14\dfrac{3}{10}

Therefore, the value of the difference is 14\dfrac{3}{10}.

PLS HELP ME NOW ITS PYTHAGOREAN THEOREM
rusak2 [61]

Answer:

a =2.2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2+2^2 = 3^2

a^2 +4 = 9

a^2 = 9-4

a^2 = 5

Taking the square root of each side

sqrt(a^2) = sqrt(5)

a = sqrt(5)

a=2.236067977

To the nearest tenth

a =2.2
