Aderyn is making a vegetable stew for = 6 people.

A recipe indicates that 5 ounces of finally diced onions are needed for = 2 people

1 ounce = 28 grams.

So for 1 people onions are needed = 5/2 = 2.5 ounces or 70 grams.

Therefore, finally diced onion are needed for 6 people = 70 × 6 = 420 grams.

What is 4.45 repeating as a fraction.

KiRa [710]

This would be so easy for you to solve, in about 3 minutes with a calculator.

A fraction means division ... (the top number) divided by (the bottom number).

Take the fraction part of each choice, do the division for each one,
and see which one gives you 0.4545... repeating.

A). 227/500 = 0.454 That's not 0.45 repeating.

B). 9/20 = 0.45 That's not 0.45 repeating.

C). 5/11 = 0.4545... THAT's 0.4545... repeating !

D). 9/2 = 4.5 That's not 0.45 repeating.

How many ways are there to select 12 countries in the United Nations to serve on a council if 5 are selected from a block of 45,

melomori [17]

Answer:

There are 436937109262510348800 ways to selected 12 countries.

Step-by-step explanation:

Let $x_1, x_2, x_3, x_4,x_5$ the countries selected from the block of 45. For $x_1$ there are 45 options of countries to select. For $x_2$ there are 44 options of countries to select because there can be no repeated countries. With the same reasoning, for $x_3$ there are 43 options, for $x_4$ there are 42 options and for $x_5$ there are 41 options.

Let $x_6, x_7, x_8, x_9$ the countries selected from the block of 57 countries. For $x_6$ there are 57 options of countries to select. For $x_7$ there are 56 options of countries to select because there can be no repeated countries. With the same reasoning, for $x_8$ there are 55 options and for $x_9$ there are 54 options.

Let $x_{10}, x_{11}, x_{12}$ the countries selected from the block of 69 remain countries. For $x_{10}$ there are 69 options of countries to select. For $x_{11}$ there are 68 options of countries to select because there can be no repeated countries and for $x_{12}$ there are 67 options.

For find the total of options o ways to select 12 countries we multiply the above options.

$45*44*43*42*41*57*56*55*54*69*68*67= 436937109262510348800$
