Answer:
There are 60 permutations that can be formed from the first five letters of the alphabet.
Step-by-step explanation:
The number of three letter permutations that can be formed from the first five letters of the alphabet is
.


= 60
Hence, there are 60 permutations that can be formed from the first five letters of the alphabet.
Answer:
$48.00
Step-by-step explanation:
$3.00 / 6.5 oz = [unknown $] / 104 oz
unknown $ = 104 oz * $3.00 / 6.5 oz
unknown $ = 16 * $3.00 ((oz/oz cancels out))
unknown $ = $48.00
You'd simply have to find 20% of $40. To find the percent of a number, you would change the percent into an actual decimal/number, and then multiply them both. So the percent would become 0.20.
40 × 0.20 = 8
So now you would subtract 8 from the cost of 40.
40 - 8 = 32.
The shirt costs $32.
Answer:
72
Step-by-step explanation:
Use PEMDAS
Parentheses
Exponent
Multiplication and Division (if it contains both, just go from left to right)
Addition and Subtraction (if it contains both, just go from left to right)
8 + (5)(4) − (6 + 10/2) + 55
8 + 20 − (6 + 10/2) + 55
28 − (6 + 10/2) + 55
28 − (6 + 5) + 55
28 − 11 + 55
17 + 55
72
To solve it step by step with PEMDAS:
Solve within the parentheses
6 + 10/2
10/2 = 5
6 + 5 = 11
Multiply/Divide
(5)(4) = 20
Add/Subtract
8 + 20 - 11 + 55 = 72
