The estimate would be 1200.
We will set up a proportion for this. 10 out of 60 of the sample were tagged, so that is the first ratio. The 200 that were tagged would be in the numerator of the second ratio (10 was the portion tagged, and 200 is the portion tagged, so they both go on top). We do not know the total number so we use a variable:
10/60 = x/200
Cross multiply:
10*x = 60*200
10x = 12000
Divide both sides by 10:
10x/10 = 12000/10
x = 1200
S < 20 , -5x > -100 , etc
Answer:
4; y-5=2(x+3)
Step-by-step explanation:
Question 1: 8y-18=14
8y=32
y=4
Question 2: y-5=2(x-(-3)
y-5=2(x+3)
C=p(t+30)
Let’s substitute in our values...
c=2(245+30)
Get the sum of what we have in parentheses...
c=2(275)
And finally
c=550
160 times 1.75 gives you 280 which means that it takes 160 secs to move a total of 280 feet
