The number of tennis ball that will fill the room is <u>1,371 tennis balls.</u>
<em><u>Given</u></em>:
Diameter of ball (d) : 2 inch
Radius (r) = half of diameter = 1 inch
Dimension of room = 20ft by 16ft by 18ft
Number of balls that will fill the room = Volume of each ball/volume of the room
Volume of the ball = volume of a sphere = 
Where,
r = 1
let 
<em>Substitute</em>:
Volume of the room = 
Therefore:
number of tennis balls that will fill the room = 
Therefore, the number of tennis ball that will fil the room will be <u>approximately 1,371.</u>

Answer: $29.10
Step-by-step explanation:
Shoes:
10% of 24 is 2.4
The shoes cost 21.60 with the 10% discount and before tax.
Belt:
25% of 10 is 2.5
The belt cost $7.50 with the 25% discount and before tax.
Total:
You still owe 29.10 for the belt and shoes before tax.
You saved $2.4 on the shoes and $2.5 on the belt (total of $4.90)
So 11 and a half day so count up how the hours in a day so 24 hr and multiply it by 11 and 0.5 ( bc 0.5 is 1/2)
That’s the first part Ik how to do
1+7 and 7+1 equal the same amount. It doesn't matter which position the number is in. The sum will be 8 either ways. Hope that helps :)
Answer:
where 
Step-by-step explanation:
This is an arithmetic sequence with the first term is 
= -2.7 and has a common difference of 
.
Arithmetic Sequence: 
is the nth term and 
is the common difference.
The common difference: -2.7, -8.3, -13.9...
Subtract: -2.7- (-8.3) = -5.6, -13.9 - (-8.3) = -5.6
Common difference: 
Recursive rule:
