<span>The numbers (not counting 69) are all perfect squares. They are 7 squared, (what should be, possibly) 8 squared, 9 squared, and 10 squared. The next three numbers in the sequence would then be 121, 144, and 169.</span>
For this problem, let x be the number of children and y for adults. Formulate the equations: 1st equation, x + y = 3,200 and 2nd equation 5x + 9y = 24,000. Re-arrange 1st equation into x = 3200 - y. Then, substitute into 2nd equation, 5(3,200-y) + 9y = 24,000. Then, solve for y. The 16,000 - 5y + 9y = 24000. Final answer is, y = 2000 adults went to watch the movie.
Answer:
65
Step-by-step explanation:
C^2= A^2 + B^2
C^2 = (60)^2 + (25)^2
C^2 = 4225
Take the square root of C
C = 65
Angle 1&3 is 70° becuase 180-110= 70
Angle 4 is 110° becuase it is the alternate exterior angle to Angle 2, which equals 110°.
Hope this helps!
