There are 400 balcony seats in the concert hall.
<u>Step-by-step explanation</u>:
Step 1 :
- The number of lower seats = 450 seats
Total seats = Lower seats + balcony seats
Step 2 :
- Tickets sold = 170 tickets
- Total tickets = x
Tickets sold = 1/5 of total tickets.
⇒ 170 = (1/5)x
⇒ x = 5
170
⇒ x = 850 tickets
∴ Total seats in the concert hall is 850.
Step 3 :
Total seats = 450 + balcony seats
850 - 450 = balcony seats
∴ balcony seats = 400
Answer:
Step-by-step explanation:
<u>Function given:</u>
Evaluate the function for an input value of 3
<u>Input value is x = 3, output value is:</u>
- f(3) = -4(3²) – 3(3) – 5 = -4(9) - 9 - 5 = -36 - 14 = -50
- f(3) = -50
Answer:
1. 1/4+1/4=2/4=1/2
2. Yes
3. i don't know
4. Yes
Step-by-step explanation:
1. 1+1=2 therefore you get 2/4 or 1/2
2. 2/3 is the reduced form of 4/6
3. i honestly dont know
4. 3/4 is the reduced form of 9/12
Convert 2/5 to a decimal and you get .4, or 40%. 40% of the band members also sing, so yes, the band has the same number of string instrument players and singers.
Usaully if you add a larger number with a smaller negative number you will get your answer is 8 + -4+4
