Answer:
1/4 ft
Step-by-step explanation:
Area is equal to length times width
A = lw
1/2 = 2*w
Divide each side by 2
1/2 ÷2 = 2w/2
1/4 = w
6 for 2 refills. Since its less money and you still get refills.

Answer:
y = -3x +6
Step-by-step explanation:
The perpendicular line will have the coefficients of x and y swapped (and one of them negated), and will have a constant appropriate to the point the line needs to go through.
The equation will look like ...
x -3y = 3 . . . . . . . . . . . . . given line
3x +y = constant . . . . . . perpendicular line
where "constant" can be found by substituting for x and y.
3x +y = 3(5) +(-9)
3x +y = 6 . . . . equation in standard form
To put this in slope-intercept form subtract 3x:
y = -3x +6
Answer:
The surface area is 10.26 feet.
Step-by-step explanation:
A=lw+l(w
2)2+h2+w(l
2)2+h2=0.8·0.8+0.8·(0.8
2)2+62+0.8·(0.8
2)2+62≈10.26131
