How do you make the number 9 with five 2s only?
You can make the number 9 using five 2s by adding them together like this: 2 + 2 + 2 + 2 + 2 = 10, then subtracting 2: 10 - 2 = 8, then dividing by the remaining 2: 8 ÷ 2 = 4, and finally adding two more 2s: 4 + 2 + 2 = 9.
-4 plus 3 plus 2s 15?
If you mean: -4+3+2s = 15 then s = 8
What is the range of numbers that can be encoded in 4 bits using 2s complement notation?
Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.
What percentage of 8 is 2?
Four 2s make 8, so 25% is your answer
If 2 sandwiches and 1 drink is 10.00 1 sandwich and 2 drinks is 8.00 How much is each sandwich?
This is easy. Make two equations, and represent the sandwiches with s and the drink with d. you get: 2s+d=10 s+2d=8 After simplifying and taking away a variable, you figure out that each sandwich costs 4 dollars and each drink costs 2 dollars. (Heres the step by step algebra) 2s +dy = 10 s + 2d = 8 2s + d = 10 2s + 4d = 16 3d = 6 d = 2 2s + d = 10 2s + 2 = 10 2s = 8 s = 4 So, Sandwich = £4 Drink = £2
How can you use 2s and 1s facts to find 3x8?
To find (3 \times 8) using 2s and 1s facts, you can break it down into simpler components. First, recognize that (8) can be expressed as (4 + 4), so (3 \times 8) can be rewritten as (3 \times (4 + 4)). This gives you (3 \times 4 + 3 \times 4). Since (3 \times 4 = 12), you can add (12 + 12) to get (24). Thus, (3 \times 8 = 24).
How many atoms of hydrogen are present in NH4 2S?
There are 8 atoms of hydrogen present in NH4 2S. This is because there are 4 hydrogen atoms in each ammonium ion (NH4+) and there are 2 ammonium ions in NH4 2S.
Can you make 24 by using 8 8 7 4?
(7 - (8 ÷ 8)) × 4 = 24

2, 4, 6, 8, 12, 14, 16
How can you make 24 using numbers 9 4 8 8?
8x(4-(9-8)=24
How do you make -9 using four 4's?
0-4=-4 -4-4=-8 8-4/4=-9
How do you make 24 by using 8 3 4 3?
