Answer:

9 feet

Step-by-step explanation:

The height of the ball in feet is given by the polynomial:

h(t) = -16t^2+50t+3

where t is the time in seconds.

After 3 seconds, t = 3:

h(3) = -16(3)^2 + 50(3) + 3 \\\\h = -144 + 150 + 3 = 9 feet

The height of the ball after 3 seconds is 9 feet.

Last month you purchased 6 individual songs and 1 albums for a total of $21.99.
Annette [7]

Answer:

Song =$1.50 Album =$12.99

Step-by-step explanation:

Lets assume Individual songs = x

albums=y

6x + y = 21.99-------- y= 21.99- 6x

4x + 3y= 44.97

Replace y in the second equation

4x+ 3(21.99-6x) = 44.97

4x +65.97- 18x = 44.97

14x= 21

x = 1.50

y= 21.99- (6*1.50)

= 12.99

725 tickets were sold for a game for a total of $1,487.50. If adult tickets sold for $2.50 and children's tickets sold for $1.50
weqwewe [10]

Answer:

  • 400 adult tickets
  • 325 children's tickets

Step-by-step explanation:

Let x represent the number of adult tickets sold. Then 725-x is the number of children's tickets sold, and the total revenue is ...

  2.50x +1.50(725 -x) = 1487.50

  1.00x + 1087.50 = 1487.50 . . . . . eliminate parentheses

  x = 400 . . . . . . . . . . . . . . . . . . . . . subtract 1087.50

There were 400 adult tickets and 325 children's tickets sold.
