Ahat [919]

Answer:

<h2>A = 37 cm²</h2>

Step-by-step explanation:

Look at the picture.

We have two rectangles:

15cm × 2cm and 7cm × 1cm.

Calculate the areas:

A₁ = 15 · 2 = 30 cm²

A₂ = 7 · 1 = 7 cm²

The area of the figure:

A = A₁ + A₂ → A = 30 cm² + 7 cm² = 37 cm²

18 cajas de manzanas y peras fueron llevadas a la escuela. Las peras trajeron 210 kg en 6 cajas. ¿Cuántos kilos de manzanas fuer
Katyanochek1 [597]

Answer:

504 kilos de manzanas fueron llevados a la escuela.

Step-by-step explanation:

Sean x, y la cantidad de cajas de manzanas y peras, respectivamente. De acuerdo con el enunciado, tenemos el siguiente sistema de ecuaciones:

Total de cajas

x+y = 18 (1)

Masa de cada caja de peras

y\cdot m_{P} = 210 (2)

y = 6 (3)

Masa de caja de manzanas

m_{M} = m_{P}+7 (4)

De (2) en (3), tenemos que la masa de cada caja de peras es:

m_{P} = 35\,kg

Por (4), encontramos que la masa de cada caja de manzanas es:

m_{M} = 35\,kg+7\,kg

m_{M} = 42\,kg

Finalmente, de (1) tenemos la cantidad de cajas de manzana:

x = 18-y

x = 12

La cantidad de kilos de manzanas llevada a la escuela se obtiene al multiplicar la cantidad de cajas de manzana por la masa de cada caja:

M = (12)\cdot (42\,kg)

M = 504\,kg

504 kilos de manzanas fueron llevados a la escuela.

AnnyKZ [126]

Answer:

50 pens

Step-by-step explanation:

x= 25 percent of 200

25/100 times X/200

Cross multiply them and you get

100x=5000

X=5000/100

X=50

25 percent of 200 is 50.

Which means they have away 50 pens
