Why do some merchants, particularly smaller businesses, set a minimum purchase of $10 for any credit card transaction, or simply

amm1812

Because accepting credit cards cost the business small transaction fees. These businesses already have a paper thin profit margin, meaning if you buy less than $10 and use credit card, their profit is little to non-existent.

LA BASE DE UN RECTANGULO ES 8 M MAYOR QUE LA ALTURA, EL AREA MIDE 65 METROS CUADRADOS ¿CUANTO MIDEN LA BASE Y ALTURA?

sp2606 [1]

Answer:

23 m and 15 m

Step-by-step explanation:

THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?

Let the height of the rectangle is h.

Base = 8+h

Area of the rectangle, A = 65 m²

We need to find the base and height of the rectangle. The area of a rectangle is given by :

A = bh

So,

$65=(8+h)\times h\\\\65=8h+h^2\\\\h^2+8h-65=0\\\\(h-5)(h+13)=0\\\\h=5\ m\ \text{and}\ x=-13\ m$

Neglecting negative value, h = 15 m

Base = 8+15 = 23 m

So, the base and height of the rectangle is 23 m and 15 m respectively.
