Answer:
A.) About 90
Step-by-step explanation:
From the given table, the biologist tagged 150 trout. Also, he recaptured a total of 100 trouts of which 60 were recaptured with tags.
Thus, let the trout population in the lake be represented by x,
= 
Cross multiply to have;
100 × x = 60 × 150
100x = 9000
Divide both sides by 100,
x = 
= 90
Therefore, the trout population is about 90 in the lake.
Let x be the amount of apples that Kevin bought.
It says that john buys three more than twice the amount of apples that kevin buys, so 3 + 2x apples.
They bought 21 apples total, so x + 3 + 2x=21
Collecting like terms gives 3x+3=21
Subtracting 3 from both sides gives 3x=18 and then dividing both sides by 3 gives x=6
x is the amount of apples kevin bought, so kevin bought 6 apples
Point slope:
y-(-2)=-1/3(x-9)
slope intercept:
solve the point slope form
y+2 = -1/3x+3
y=-1/3x+1
Answer:
C
Step-by-step explanation:
"25%" means "0.25"
"of" means "times"
You said 11 members = 0.25 x (the club)
Divide each side by 0.25 : The club = (11 / 0.25) =<em> 44 members
