Answer:each class would buy 35 rolls.
Step-by-step explanation:
Let x represent the number of rows of either floral sheeting or vinyl glasses that each class would buy.
The freshmen have already spent $307 on their float, plus they need to buy floral sheeting that costs $69 per roll. This means that the total cost of buying x floral sheetings would be
307 + 69x
The sophomores, who have spent $342 so far on theirs, still need to purchase vinyl grass at $68 per roll. This means that the total cost of buying x vinyl grass would be
342 + 68x
Since they are buying the same number of rolls to cover the same area, then
307 + 69x = 342 + 68x
69x - 68x = 342 - 307
x = 35
Answer:
Permeabilidad
Step-by-step explanation:
La permeabilidad es la medida de la capacidad o facilidad con la que un medio o material poroso permite el paso o la penetración de un fluido (líquido o gas) a través de él.
Un material altamente permeable como la grava permite que el fluido fluya a través de él fácilmente con poca restricción, de modo que prácticamente todo el fluido tiene el potencial de fluir a través de una columna de grava.
Un material poco permeable como la arcilla impide o restringe el flujo de fluido a través de él.
La permeabilidad se mide en un laboratorio utilizando muestras centrales de un material.
La unidad de permeabilidad es m²

Answer:
C The center is located at (-4, 3), and the radius is 6.
Step-by-step explanation:
The formula for a circle is
(x - h)² + (y - h)² = r²
(h, k) is the center
r is the radius
--------------------------
(x + 4)² + (y - 3)2 = 36
(h, k) = (-4, 3)
r = √36 = 6
Therefor
C The center is located at (-4, 3), and the radius is 6.
