A right rectangular prism's edge lengths are 12 inches, 2 1/6 inches, and 4 inches. How many unit cubes with edge lengths of 2/3
zhenek [66]

Answer:

<h2>324 cubes</h2>

Step-by-step explanation:

We calculate how many cubes will fit along each edge:

12 in : 2/3 in = 12 · 3/2 = 18 cubes

2 1/6 in : 2/3 in = 13/6 · 3/2 = 39/12 = 13/4 = 3 1/4 → 3 cubes

4 in : 2/3 in = 4 · 3/2 = 6 cubes

(18)(3)(6) = 324

Which inequality is graphed in red
mina [271]

Answer:

y>x-2

Step-by-step explanation:

When we see an inequality on a coordinate plane, we first treat it like a linear equation. The red inequality, or the red line, clearly has a positive slope. One can assume that this slope is 1. This line is also 2 units down, making the inequality x-2. There you have it!

Furthermore, we can tell it is the 1st choice because the line is dashed. In inequalities, the line is only dashed when the inequality contains < or >. Also, the shading is "above" the line, meaning the y must be greater than the line.
