Hey can you please help? I am struggling a lot don’t know how to solve this

64.8

Step-by-step explanation:

Pythagoreon Theroem

a^2 + b^2 = c^2  in  this situation it would actually be the opposite, seeing where the "x" is (on a leg) c^2 - b^2 = a^2. First  take the square of 67 and 17

67 squared is 4489 and 17 squared is 289 then  subtract both results

4489-289 = 4200 take the square root of this number

64.8074  (Round to the tenths 64.8)

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.
