What is the scale factor from Figure A to Figure B?

bearhunter [10]

Answer:

Step-by-step explanation:

To find the Scale factor we use this formula:

Scale factor / K = Dimension of the new shape ÷ Dimension of the original shape

Substitute any 2 corresponding sides into the formula:

I took 1 and 4:

K = 1 / 4

K = 0.25

I'm not sure which form the question is so I will leave it here.

Hope this helped. Brainliest please?

Klaus was replacing the roof on his house. He used 420 nails to attach all the pieces of wood. Each piece of wood needed 7 nails

jeyben [28]

Multiply 40x7 then subtract that total you got from multiplying 40x7 with 420

40x7=160

420-160=260

260 pieces of wood were left.

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.
