a ruby throated hummingbird beats its wing 159 times in 3 seconds.how many times does the ruby throated humming beat its wings per second

Answers

159 divided by 3 will give you the answer of 53.
159 divided by 3 because you have to find out how many times the bird flaps his wings in a second so by dividing that you will get your answer here look 159 divided by 3 will equal 53 and that is the answer the work to show how you got the answer is just dividing 159 by 3 :)

Does a polygon have more sides or angles?

Answers


I think you're asking:  "Which does a polygon have more of ... sides or angles ?"

This is a perfect example of where you spent more time and effort
posting your question on the internet than what it would take you
to answer it for yourself.

Can you draw a picture of a triangle ? 
You'll see it has 3 sides and 3 angles.

Can you draw a picture of a square ? 
You'll see it has 4 sides and 4 angles.

Can you draw a picture of a shape with 5 sides ? 
You'll see that it has 5 angles.

Can you draw a shape with 6 sides (like s STOP sign) ?
You'll see that it has 6 angles.

By now, you would be getting the crazy hunch that maybe the
sides and angles of a polygon always happen in the same number. 
THEN you would get on Brainly and ask: "I have been working
with some polygons, and I noticed that every polygon I tried had
the same number of angles as it had sides.  Is this always true
for any polygon ?"

If I saw that question, I would jump on it with joy, because it feels
so good to help someone who doesn't mind putting some of his
own time and effort into a question.

I would answer "YES !", and then find 15 other characters to fill the minimum.
 
quadrilateral, triangle, hexagon, pentagon, etc are polygons
it depends on what kind of shapes like how many sides
but ex : rectangle has more sides than triangles so some of them yes, and some of them, no

A tank holding 600 liters of milk is leaking. Each week it loses 60 liters of milk. Let M be the liters of milk remaining in the tank after leaking for t weeks.Is M a linear function or an exponential function?

Why?

Answers

linear, because the tank will eventually be empty. In about 10 weeks

Final answer:

The liters of milk remaining in the tank after leaking for t weeks is represented by an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent.

Explanation:

The function that represents the liters of milk remaining in the tank after leaking for t weeks is an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent. In this case, the liters of milk lost each week is constant, so the amount of milk remaining in the tank is decreasing exponentially over time.

Formula for exponential decay: M = P * (1 - r)^t, where M is the amount of milk remaining, P is the initial amount of milk, r is the rate of decay, and t is the number of weeks.

In this case, the initial amount of milk, P, is 600 liters and the rate of decay, r, is 60/600 = 0.1 (10%). So the exponential function that represents the liters of milk remaining after t weeks is M = 600 * (1 - 0.1)^t.

The polynomial 2x3 − 5x2 + 4x − 10 is split into two groups, 2x3 + 4x and −5x2 − 10. The GCFs of each group is then factored out. What is the common binomial factor between the two groups after their GCFs have been factored out?

a)2x + 5
b)2x − 5
c)x2 − 2
d)x2 + 2

Answers

2x³ - 5x² + 4x - 10

(2x³ + 4x) + (-5x² - 10)

2x(x² + 2) - 5(x² + 2) = Answer is Choice D. x² + 2

The common binomial factor between the two groups after their GFCs factored out 2x + 5.

The correct option is (A)

What  is GCF?

The greatest commonfactor (GCF) of a set of numbers is the largest factor that all the numbers share.

Given: 2x³ - 5x² + 4x - 10, splits into (2x³ + 4x) + (-5x² - 10)

So, to find the GCF factorise each term

= (2x³ + 4x) + (-5x² - 10)

= 2*x*x*x+2*2*x-5*x*x-2*5

= 2x(x²+2)-5(x²+2)

= (2x-5) (x²+2)

Hence, the  common binomial factor between the two groups (2x-5).

Twenty-four blue socks and twenty-four red socks are lying in a drawer in a dark room. What is the minimum number of socks you need to pull out of the drawer so that you are sure to have at least two blue socks

Answers

Answer:

26 socks

Step-by-step explanation:

There are a total of 48 socks here. Let us assume you pulled out 24 socks at a go and all are red. Now, you would have exhausted the number of red socks here. You would be left with only blue socks which you can pull one after the other to give a total of  26 socks pulled out to have 2 blue socks at least.
