Answer:
We can estimate a population of 500 birds.
Step-by-step explanation:
We can estimate the total bird population using a rule of three with the information given:
If we find 5 birds with the foot band among 100 birds captured, how many birds there are in total if inicially we put foot bands in 25 birds?
5 birds with foot band -> 100 birds captured
25 birds with foot band -> X total birds
X * 5 = 25 * 100
X = 25 * 100 / 5 = 500 birds
We can estimate a population of 500 birds.
14$ i think and good luck on ur test
<span>3x=4y=7z
so
GCF:
3 * 4 * 7 = 84
3x = 84
x = 28
4y = 84
y = 21
7z = 84
z = 12
</span><span>least possible value for
</span><span>x + y + z = 28 + 21 + 12 = 61
</span>
answer
(d) 61
Answer:
Step-by-step explanation: You need to find a the lowest number that the denominators can be timed by. In you're case. You can just times 5 by 2 = 10
So that both the denominators are 10. And the denominator that was once 5. The numerator of that fraction also needs to be timed by 2.
So then you have 7 18/10 - 6 15/10
Then you can convert them to to proper fractions 8 8/10 - 7 5/10
Then you can take away the fractions so it's
8 8/10 - 7 5/10 = 1 3/10
Answer:
the formula used gives surface area instead of volume
