Answer:
$3.05
Step-by-step explanation:
Backpack=$18.70
6 note books=x
Sales tax=6%
Total cost=$39.22
18.70+x+0.06(18.70+x)=39.22
18.70+x+1.122+0.06x=39.22
19.822+1.06x=39.22
1.06x=39.22-19.822
1.06x=19.398
x=19.398/1.06
=18.3
x=$18.3
6 books=$18.3
Each book cost=18.3/6
=$3.05
Answer:
. r=9 inches is the answer.
Answer:
The answer to your question is A = 200.96 u²
Step-by-step explanation:
Data
Radius A = 6
Radius B = 2
π = 3.14
Area = ?
Formula
Area = πr²
Process
1.- Calculate the radius of the large circle
Radius = radius of circle A + radius of circle B
Radius = 6 + 2
Radius = 8
2.- Substitute in the formula
Area = (3.14)(8)²
Area = 3.14(64)
Area = 200.96 u²

Answer: 48 tickets
Step-by-step explanation:
Since the expression that gives the number of tickets a player wins if he shoots the ball in the hoop t times is expressed as 3t.
Therefore, the number of tickets that a player wins if he shoots the ball in the hoop 16 times will be:
= 3t
where,
t = 16
Therefore, 3t = 3 × 16 = 48
The player wins 48 tickets.
