Answer:
Poli (muchas) edro (caras) luego sería muchas caras lo que representas las figuras poliédricas.
Step-by-step explanation:
La palabra poliedro viene del griego clásico πολύεδρον (polyedron), de la raíz πολύς (polys), «muchas» y de ἕδρα (hedra), «base», «asiento», «cara».
Answer:
- length: 32 in
- width: 21 in
Step-by-step explanation:
If the width of the original piece of sheet metal is x, then the length is 2x-10. Subtracting a 5" square from each corner makes the bottom of the box have dimensions (x-10) and (2x-20). The volume of the box is then ...
5(x -10)(2x -20) = 1210 . . . . . . volume is the product of the dimensions
10(x -10)² = 1210 = 10(11²) . . . . factor the equation
(x -10)² = 11² . . . . . . . . divide by 10
x = 11 + 10 = 21 . . . . . .take the square root, add 10
The length and width of the original piece of sheet metal were 32 inches and 21 inches, respectively.
Hello from MrBillDoesMath!
Answer: line EF
Discussion: Two lines, L1 and L2, with slopes m1 and m2 are perpendicular if
m1 * m2 = -1. In our case m1 = -1/3 so the slope of the perpendicular line is 3.
( 3 * (-1/3) = -1). The line with slope 3 is rising as x gets larger. The only line shown fitting this is line EF. Note that line AB is "falling" as x increases so it can not possibly be the answer.
