With a 10 percent tax, you have 90 percent left. 75*.9=$67.50
-10 and 2
-10 x 2 = -20
-10 + 2 = -8
Answer:I am a little confused by your wording but I am assuming the question is 12 times what is 26 greater than 6
The answer would be 2.66666666667 which sound incorrect but multiply by 12 and you get 32 and 6 + 26= 32
Step-by-step explanation:
Answer:
It takes at least 7 months for the cat to be at least 6 kg lighter than the original weight.
Step-by-step explanation:
Use exponential decay formula:
A = P (1-r)t
A = amount decreased to
P = original amount
r = rate of decrease
t = time
6 ≥ 12 (1-0.10)t divide both sides by 12
0.5 ≥ (0.9)t take log of both sides
log (0.5) ≥ log (0.9)t power rule of logs lets the exponent t drop to front of log to become a factor
log (0.5) ≥ t log(0.9) divide both sides by log(0.9) which is negative so reverse the inequality sign
log (0.5) / log (0.9) ≤ t use calculator
6.57 ≤ t
It takes at least 7 months for the cat to be at least 6 kg lighter that original weight.
check:
12 (0.9)7≈ 5.73
12 (0.9)6 ≈ 6.37
