Answer:
266
Step-by-step explanation:
Let no. of main floor tickets = x
Balcony tickets = x + 100
4(x+100) + 12(x) = 3056
4x + 400 + 12x = 3056
16x = 3056-400
16x = 2656
x = 2656/16
x = 166
No. of Balcony tickets = x + 100 = 166 + 100 = 266
Answer:
3, 000
Step-by-step explanation:
+2, 500 rounds up
(y-k)²/a² + (x-h)²/b² = 1
Vertices being : A(0,1) & B(0, - 9), means that h=0
Let's calculate k: Af₁ + Af₂ = |2+8| = 2a = 10 → a=5 (f₁ and f₂ = focii)
1) a = 10 (WRONG) since a =5
2) h=3 (WRONG) since h =0
3) k =0 (WRONG) since k =5
4) b = 4 RIGHT; PROOF:
we know that : c² = a² - b²
c= 3 & a = 5 then → 3² = 5² - b²
9 = 25 - b²
b² = 25-9 = 16 and b = 4
