These are the only numbers you can multiply to get to 18.
1x18
2x9
3x6
18x1
9x2
6x3
Number of 1/2-inch cubes length-wise = 8 1/2 ÷ 1/2 = 17
Number of 1/2-inch cubes width-wise = 5 1/2 ÷ 1/2 = 11
Number of 1/2-inch cubes height-wise = 2 1/2 ÷ 1/2 = 5
Number of 1/2-inch cubes = 17 x 11 x 5 = 935

Hey there! :)
Answer:
arc AB = 2.5π in (in terms of pi) or ≈7.85 in. (pi = 3.14)
Step-by-step explanation:
Begin by finding the circumference of the circle. Use the formula:
C = 2rπ
C = 2(9)π
C = 18π.
Since ∠AQB equals 50°, set up a ratio to find the length of arc AB:

Cross multiply:
50 · 18π = 360x
900π = 360x
Divide both sides by 360:
x = 2.5π in, or ≈7.85 in.
Answer:
Here, x represents the weekly sale
As per the statement:
A salesperson earns $320 per week plus 8% of her weekly sales.
"8% of her weekly sales" means 
then;
the expression which represents her earning = 
"At least" means 
then;
the sales necessary for the salesperson to earn at least $1000 in the one week
⇒
Subtract 320 from both sides we have;

Divide both sides by 0.08 we get:

Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e
