  18.3 m

Step-by-step explanation:

The Pythagorean theorem is helpful here. It tells you the sum of the squares of the sides of the triangle is equal to the square of the hypotenuse.

  h^2 + 31^2 = 36^2

  h^2 = 36^2 -31^2 = 1296 -961 = 335

  h = √335 ≈ 18.303

Rounded to the nearest tenth, the height of the building is 18.3 m.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
