Number of ways of picking a smaller number out of a bigger number is called combination.
Number of way of picking 3 stamps out of 4 is 4C3 (4 combination 3) = 4! / (3! x (4 - 3)!) = 4! / (3! x 1!) = (4 x 3 x 2 x 1) / (3 x 2 x 1 x 1) = 24 / 6 = 4 ways.
Answer:
the answer is 77.77777(repeating)
Step-by-step explanation:
77 and 7/10 approximately
just as the problem states, multiply the cost (18.10) by 0.15
18.10 * 0.15 = 2.72
the tip was $2.72
| -6x - 3 | > 15
This expression can be written as:
a) -6x - 3 > 15
b) -15 > - 6x - 3
Solving a part:
Solving b part:
or we can write:
x > 2
So the solution to given inequality is:

The second option correctly lists this solution.
Answer:
3 × 3 × 1.5
Step-by-step explanation:
Volume = base area × height
13.5 = s² × ½s
½s³ = 13.5
s³ = 27
s = 3
½s = 1.5
Dimensions:
3 × 3 × 1.5
