the amount of mil available per child in a day care centrr is given by the function m(x) =25/x, where x is the number of childre
Lubov Fominskaja [6]

Answer:

0.5 liters of milk are available per child.

Step-by-step explanation:

Amount of milk available per children:

The amount of milk, in liters, available for x children is given by:

m(x) = \frac{25}{x}

50 children are present on a day

This means that x = 50

How much milk is available per child?

This is m(50). So

m(50) = \frac{25}{50} = 0.5

0.5 liters of milk are available per child.

I Need The Answer Plz!!! Geometry Is Hard!!!
Scorpion4ik [409]

Answer:

B. 10

Step-by-step explanation:

First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)

Let's first label the leg of the second triangle as y.

Then, we can set up this equation

\frac{21}{y} =\frac{y}{4}

Cross multiplying gives us

84=y^2

So, y=sqrt(84) or 2 sqrt(21).

Now, using the pythagorean theorem, we get

4^2+2sqrt(21)^2=x^2

100=x^2

x=10

An author published a book which was being sold online. The first month the author sold 21000 books, but the sales were declinin
Wittaler [7]

Answer:  119,616

You may have to erase the comma when inputting the answer.

=======================================================

Explanation:

The author sells 21,000 books in the first month.

Then they sell 21,000*(1-0.12) = 21,000*(0.88) = 18,480 in the second month.

Then they sell 18,480*(1-0.12) = 18,480*(0.88) = 16,262.4 = 16,262 in the third month.

And so on. These values follow a geometric sequence with first term a = 21,000 and common ratio r = 0.88

We can think of the 0.88 as 88% of the original value (since losing 12%, we keep the remaining 88%)

-------------

Use the formula below to sum the first 9 terms of the geometric sequence

Plug in a = 21000 and r = 0.88

S_n = a*\frac{1-r^n}{1-r}\\\\S_9 = 21000*\frac{1-0.88^9}{1-0.88}\\\\S_9 \approx 21000*\frac{0.6835216}{0.12}\\\\S_9 \approx 21000*5.6960133\\\\S_9 \approx 119,616.2793\\\\S_9 \approx 119,616\\\\

The author sold about 119,616 books over the course of the first nine months.
