Answer:
yes, the meal costs 25.60
Step-by-step explanation:
I used a slightly different method but B (Yes. They have enough to pay their bill: 21 dollars times 1.06 = 22 dollars and 26 cents and 22 dollars and 26 cents times 1.15 = 25 dollars and 60 cents.) is correct.
21*0.06=1.26
1.26+21=22.26
22.26*0.15=3.34
22.26+3.34=25.60
5)7÷0.002 = 35006)0.718÷0.2 = 3.59
7)0.0141÷0.003 = 4.7
8)0.24÷0.012 =20
9)1.625÷0.0013 = 1250
10)47.1÷0.15 =314
Initial population of rainbow smelt: 227.
Initial population of bloater fish: 1,052.
t - number of the years;
The equation is:
227 - 19.76 t = 1,052 - 92.57 t
92.57 t - 19.76 t = 1,052 - 227
72.81 t = 825
t = 825 : 72.81
t = 11.33 years = 11 1/3 years = 11 years 4 months
Answer: After 11 years and 4 months.
Answer:
The answer is d.
Draw the ray from 12 downward
p=3h + 3u subtract 3u from both sides
p-3u=3h now divide both sides by 3
h = p/3 - u
