Answer:
91
Step-by-step explanation:
90.5 needs to be a whole number, and if it ends in 5 you round it up
"Undefined" slope means the line on the graph is vertical, and that
tells the whole story right there. The 'x' coordinate is the same for
every point on the line. If (6, -1) is a point on the line, then you know
that the x-value of EVERY point on it is 6 .
It's a vertical line that intersects the x-axis at x=6, and the equation
of the line is x=6 .
27 cubes are needed because you'd need a 3x3x3 cube
P = 2l + 2w
p-2w = 2l
p-2w/2 = l
Substitute the perimeter and you should be able to work it out
Use the equation to help determine the total cost.
r is given as 8, r=8
C=2.5(8)+15
C=20+15
C=35
Nina’s total cost will be $35
