Answer:
2/3
Step-by-step explanation:
Distance MS = √[(6-(-3))²+(3-3)²]= 9
Distance M'S' = √[(4-(-2))²+(2-2)²] =6
scale factor = |M'S'| /|MS|= 6/9 = 2/3
There would be 256 bacteria after one day.
There are 24 hours in a day, and the amount of bacteria doubles every 3 hours, so it will double:
24 / 3 = 8 times.
To find the current amount we could use an equation such as:
1 * 2^8 = x
Finally, solve for the number of bacteria:
1 * 2^8 = x
1 * (2 * 2 * 2 * 2 * 2 * 2 * 2 * 2) = x
1 * (4 * 4 * 4 * 4) = x
1 * (16 * 16) = x
1 * 256 = x
x = 256
Answer:
0.945p
Step-by-step explanation:
Let the original price be p.
Increased price due to inflation = 5% of p
= 0.05 p
Price after increased 5% = p + 0.05p = 1.05p
Reduced price for a sale = 10% of (1.05p)
= 0.1 × 1.05p
= 0.105p
Price after reduction 10% = 1.05p – 0.105p = 0.945p
Hence the final price is 0.945p.
