Answer:
Remembering the properties of numbers is important because you use them consistently in pre-calculus. The properties aren't often used by name in pre-calculus, but you're supposed to know when you need to utilize them.
Answer:
76(10) + (-114)10 = (-38)10
Step-by-step explanation:
To express -114 in two complement
First convert to binary = 0000 0000 0000 0000 0000 0000 0111 0010
Change 1 to 0 and o to 1 = 1111 1111 1111 1111 1111 1111 1000 1101
add 1 to = 1111 1111 1111 1111 1111 1111 1000 1110
(76)10 complement = 0000 0000 0000 0000 0000 0000 0100 1100
Adding the two = 1111 1111 1111 1111 1111 1111 1101 1010 (-38)
0(10) in 16 -bit binary =
0000 0000 0000 0000
Answer:
$21.29 per dancer
Step-by-step explanation:
The materials cost $373.78 for all 22 dancers, so the cost per dancer is ...
$373.78 / 22 = $16.99
Adding the $4.30 cost of gloves to that brings the total for each dancer to ...
$16.99 +4.30 = $21.29 . . . . for each dancer
The perimeter of a shape is the distance around it, or all of the lengths of its sides added together. So the perimeter can be represented by s + (s + 4) + 3s.
