Answer:

i think 2.7

Step-by-step explanation:

Answer:

For the first group we have the pairs:

year           population

0                20

1                 80

2                320

3                 1,280

4                 5,120

5                 20,480

Here we can see that the population quadruples each year

(4*20 = 80, 80*4 = 320, 320*4 = 1,280, etc...)

then the population equation is:

P(0) = 20

P(1) = 20*4

P(2) = (20*4)*4 = 20*4^2

We already can see the pattern, then we can write this relationship as:

P(t) = A*(4)^(t)

Where:

t represents time in years, and A is the initial population, that we know it is 20, then:

P(t) = 20*(4)^t

This is the function that represents the table.

B) Now we have a group of 20 squirrels and the population triples each year, with the same reasoning than before we can write the equation that models this situation as:

Q(t) = 20*(3)^t

C) Now, if the initial population of the second group is 40, the equation becomes:

Q(t) = 40*(3)^t

The population by year 3 is given by replacing t by 3, then:

Q(3) = 40*(3)^3 = 1080

And the population of the other group in year 3 is seen in the table, it is 1,280, then the population of the first group is bigger by year 3, and it is greater by:

1,280 - 1,080 = 200

So the first group is larger by 200 squirrels.

Answer:

D. 211

Step-by-step explanation:

180-19=161

161+50=211

19+(211(x)-50)=180

211° is the value of x since if u substitute it u will get your answer note that angle on a straight line is 180°

Answer:

25.

Step-by-step explanation:

If the distance from Dunlap and Butte is 20 MI then the distance between Ferris and Butte  would be 25 because it wouldn’t reach from 20 all the way so it Hass to add more and 25 would be the only one .

A is not correct because 1 does not equal 1/4 +1/4.

B is correct because 1/4*1 does equal 1/5. (and all the other ones)

C is not correct because 1 does not equal 1/4*1/4

D is not correct because 1/4 does not equal 1-1/4

Please mark brainliest

Answer:

222 mL

Step-by-step explanation:

okay so lets multply them lets call the quantity of hydrocloric acid x

so 61x+ 21(277.5-x)= 53*277.5

61x+ 21*277.5-21x= 53*277.5

40x=(53-21)(277.5)

40x= (32)(277.5)

x= 222 mL

if my answer helps please mark as brainliest.

Answer:

[tex]\bold{-2x-20}[/tex]

Step-by-step explanation:

Hi there!

Let's clarify what the Distributive Property is.

It's a property that states

[tex]\bold{a(b+c)=ab+ac}[/tex]

So, we take a number a, multiply it by b and c, and add the products.

Now, let's use this property to simplify our expression:

[tex]\bold{-2(x+10)}[/tex]

[tex]\bold{-2x-20}[/tex]

Hope it helps! Enjoy your day!

Step-by-step explanation:

because look at the down the trigal and you will see that they pointing at the tree

Answer:

3

Step-by-step explanation:

P(1, 3) ⇒ P'(3, 9)

R(1, 1) ⇒ R'(3, 3)

Q(3, 1) ⇒ Q'(9, 3)

Looking at the points, it appears that the x and y coordinates are being multiplied by 3. Therefore, the scale factor is 3.

Answer:

15 total miles each hour

Step-by-step explanation:

for this situation and the information given in the question, all we have to do is divide the total amount by 3 (since its 1/3) to get the amount of total miles they drove at, wich is the speed they drove in this case

(sidenote: kinda slow if ya ask me but ok XD)

hope this helps you :D
