Pierre uses 30 grams of chocolate to make
Travka [436]

Pierre can make 3 liters of chocolate sauce from 450 grams of chocolate.

Step-by-step explanation:

Given,

Chocolate used to make 200 ml of chocolate sauce = 30 grams

Ratio of chocolate to milliliters of chocolate sauce = 30:200

Let,

x be the milliliters of sauce made from 450 grams of chocolate

Ratio of chocolate to ml of sauce = x:450

Using proportion;

Ratio of chocolate to ml of sauce:: ratio of chocolate to ml of sauce

30:200::450:x

Product of extreme = Product of mean

30*x=200*450\\30x=90000

Dividing both sides by 30

\frac{30x}{30}=\frac{90000}{30}\\x=3000

450 grams of chocolate will make 3000 milliliters of chocolate sauce.

We will convert this in liters.

1 liter = 1000 ml

3000 ml = \frac{3000}{1000} = 3 liters

Pierre can make 3 liters of chocolate sauce from 450 grams of chocolate.

small town whose population was 18,395 ten years ago, has lost 270 inhabitants each year since then. what is the present populat
sergiy2304 [10]

Answer:

15965

Step-by-step explanation:

a=18395

d= -270 (lost inhabitants every year)

n=10

tn=?

We know that,

tn= a+(n-1)×d

=18395+(10-1)×(-270)

=18395+9×(-270)

= 18395 -2430

=15965

Hence,the present population of small town is 15965.
