if a smaller square of side 3 cm is cut out from a bigger square of side 9 cm to form a new shape ,What is the perimeter of the

Verdich [7]

Need to find:

Perimeter of new square formed?

$~$

Solution:

Side of smaller square = 3cm.
Side of Bigger square = 9cm

$~$

Using formula:

Perimeter of square = 4 × side

$~$

Perimeter of smaller square:

⟹ 4 × 3

⟹ 12 cm

$~$

Perimeter of Bigger square:

⟹ 4 × 9

⟹ 36cm

$~$

Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square

⟹ 36 - 12

⟹ 24 cm

$~$

∴ Perimeter of new square formed is 24 cm.

Para festeja su cumpleaños,Nancy compró 15 paquetes de pizzetas. Si cocinó 288 pizzetas, cuántos paquetes completos le quedaron?

Lorico [155]

Answer:

Nancy consumió 12 paquetes de pizzetas y le quedaron 3 paquetes completos.

Step-by-step explanation:

En primer lugar, debemos descomponer el número total de pizzas como una multiplicación de números primos. Al realizar la descomposición factorial tenemos que:

$288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3$

Entonces, los familia de divisores de 288 es el siguiente conjunto:

$D_{288} = \{2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144 \}$

Si tanto la cantidad de paquetes de pizzetas y la cantidad cocinada de pizzetas son números enteros y positivos, siendo la última mucho mayor. Entonces, la cantidad de pizzetas debe ser un número entero y la cantidad de paquetes gastados menor a la cantidad de paquetes comprados y el número entero más cercano a esa cantidad. Entonces, concluimos que Nancy se gastó 12 paquetes de pizzetas, quedándole 3 paquetes completos.

Karen gave an equal amount of m and m's to herself and four friends. Each person receives m and m's equivalent to the largest on

Mariana [72]

Answer:

Karen had 45 m and m's candy.

Step-by-step explanation:

Let the number of m and m's candy be 'x'.

Now given:

Karen gave an equal amount of m and m's to herself and four friends.

So we can say that;

Number of people m and m's candy distributed equally = 5

Also Given:

Each person receives m and m's equivalent to the largest one digit number.

Now we know that;

Largest one digit number is 9.

So we can say that;

Each person receives m and m's = 9

We need to find number of m and m's Karen have.

Solution:

So we can say that;

Total number of m and m's Karen have is equal to Number of people m and m's candy distributed equally multiplied by number of m and m's can each person receives.

framing in equation form we get;

Total number of m and m's Karen had = $9\times5 = 45$

Hence Karen had 45 m and m's candy.
