It is definitly a they become extinct
So he knows there are definitely 66 trouts as he caught and tagged them.
The next day he caught 52, but 13 of them were already tagged, so were part of the number of trout he caught before.
So he can expect that:
66+(52-13)= 105 trout are in the lake
Answer:
Step-by-step explanation:
<u>Perimeter is</u>
<em>P = 2(l+w), where l= length, w = width</em>
<u>Substitute values to find the value of w:</u>
- 88 = 2(w + 16 + w)
- 2w + 16 = 44
- 2w = 28
- w = 14
Then
Dimensions are 14 ft and 30 ft
Answer:
x+63 = 90
x = 27
Step-by-step explanation:
The two angles are complementary, so they add to 90 degrees
x+63 = 90
Subtract 63 from each side
x+63-63 = 90-63
x = 27
-4x+4x +5y +6y = 17-6
11y=11
divide both side by 11 to isolate y
y=1
4x+6(1) = -6
subtract 6 on both sides
4x=-12
divide 4 on both sides
x=-3
