Given:
1st week: caught 45 salamanders and put leg bands on them
2nd week: caught 50 salamanders and 3 have leg bands
3/50 = 0.06 of the salamander population have leg bands.
45 / 0.06 = 750 total number of salamanders
<span>45/750 = 0.06 or 6% </span>
The reasonable estimate of the number of salamanders by the pond is 750 salamanders.
Answer:
-39
Step-by-step explanation:
This sequence follows the pattern of subtracting 7 each time. We can prove this:
31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10
So if we were to continue to the 11th term, we would subtract 7 more times.
1. 10 - 7 = 3
2. 3 - 7 = -4
3. -4 - 7 = -11
4. -11 - 7 = -18
5. -18 - 7 = -25
6. -25 - 7 = -32
7. -32 - 7 = -39
The 11th term in the sequence would be -39.
18,19 and 20 are the integers.
Step-by-step explanation:
Given three integers are;
n, n+1, n+2
According to given statement;
n+(n+1)+(n+2)=57
n=18
n+1 = 18+1 = 19
n+2 = 18+2 = 20
18,19 and 20 are the integers.

Answer:
Mr.A walked a faster rate
Step-by-step explanation:
Mr. A walked a faster rate since he walked 1 3/4 miles in 30 minutes which is 17.14 minutes a mile when dividing 30/1.75. Mr Geiger walked a slower rate 2 miles in 3/4 hours, 45/2 = 22.5 minutes per mile.
