1. En la tienda A hay una promoción que consiste en rebajar en 40% el valor del segundo producto que se compre. Mientras en la tienda B, por la compra de 4 productos, solo pagas tres y en la tienda C se aplica
un 15% de descuento en total de la compra:
A. Una persona debe comprar 4 productos iguales, cuyo valor unitario es de $12500, ¿cuánto debe
pagar en tienda A?
B. Una persona debe comprar 4 productos iguales, cuyo valor unitario es de $12500, si decide comprar
esos 4 productos en la tienda B, ¿cuánto debe pagar?
C. ¿Cuánto pagará si dicha compra la realiza en la tienda C?
D. Si Pedro debe comprar 3 artículos de $5000 cada uno, más 6 productos de $7000 cada uno, ¿qué
tienda le resulta más conveniente? Justifica tu respuesta.

in 4 days he will run   12/14

step-by-step explanation:

2500

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
