Answer:
w =< 70
(width is less or equal to 70 inches)
Step-by-step explanation:
Let l = length, w = width, h = height
Restrictions given in this question:
'sum of perimeter of the base and the height cannot exceed 130 inches'
perimeter of the base is 2 width and 2 length of the box
perimeter = 2w + 2l
Therefore, inequality involves here is
2w + 2l + h =< 130
(Note that =< here means less or equal)
Then a new condition given with
height, h = 60 in
and length is 2.5 times the width
l = 2.5w
Substitute this new condition into the equation will give us the following:
2w + 2(2.5w) + 60 =< 130
2w + 5w + 60 =< 130
7w + 60 =< 130
7w =< 130-60
7w =< 70
w =< 10
Answer:
1. C
2. C
Step-by-step explanation:
1. x =
, y = 4t +3
Solve for t:
t =
Plug in t:
y = 4(
) +3
y = 4
+3
2. x = 2t, y = t + 2
Solve for t:
t = x/2
Plug in t:
y = 1/2x + 2
Your answer is 7. I hope this helps you out.
