Alex Ar [27]

Answer:

Nancy gastó 8,58 dólares.

Step-by-step explanation:

Para calcular cuánto dinero gastó Nancy, debemos hallar la relación entre Nancy y María, tal como sigue:

M = 3N    (1)

En donde M es por María y N por Nancy

En la relación de la equación (1) tenemos que el dinero que gastó María es 3 veces lo que gastó Nancy, tal como dice el enunciado.

Entonces, podemos hallar ahora cuánto gastó Nancy:

N = \frac{M}{3} = \frac{25,75}{3} = 8,58

Por lo tanto, Nancy gastó 8,58 dólares.  

Espero que te sea de utilidad!

What does complumentary mean in geometry?
Bumek [7]
If you have a right triangle and one angle in the triangle is 45 degrees, the other would have to be complementary (an angle that adds up to another to form a right angle) so the other angle would have to be 45 degrees to make that a right angle 90 degrees. So complementary angles are two angles that add up to equal 90 degrees.

Find the volume of a pyramid with a square base, where the perimeter of the
lianna [129]

Answer:

42.7\,\,cubic\,\, meters

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = 4(side\,\,of\,\,a\,\,square)

side of a square = \frac{12.8}{4}=3.2\,\,m

Area of a square (A) = (side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = \frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters
